Thanks Carl,
Thanks for stopping me going down a never ending rabbit hole.

Good to know, makes sense and confirms the whole input as a stream being the 
issue and why mxf wrapped media works and some mp4.
I will have to think about how I can most efficiently resolve this.

If I mount the S3 bucket using S3FS I can read the file as normal which works, 
but requires the server to run S3FS and so require bespoke set up - which I am 
trying to avoid.

Perhaps I could write some code to localise the file if the first attempt fails 
with the error message…
pipe:: Invalid data found when processing input
Cannot determine format of input stream 0:0 after EOF
Error marking filters as finished.
That would work as I would be able to stream source when possible and fall back 
when not possible,  but it's not very elegant as requires a fail first.

If the issue is missing information from the source, is there a way I can pass 
information into ffmpeg at start up that I have extracted using ffprobe that 
would resolve the issue maybe?

Thanks, I use -flags +global_header -movflags +faststart on mp4 files I create 
using ffmpeg, is that the same thing?
I add for that for instant playback in browsers.
but I need to be able to accept files for transcode from third party providers 
so cannot guarantee they will be formatted using the faststart flag.

The result is very similar, but qtfaststart takes an existing mov file and
only moves the index in front of the file, leaving everything else exactly
identical while ffmpeg -i input -movflags +faststart out.mov writes a
new file (with different properties) that has the index already moved
to the beginning of the file.

Thanks for confirming Carl.

I thought I was adding the correct flags to my mp4 files but after a lot of 
testing it seems that because I am output using the tee function the flags I am 
adding are ignored and the output inherits the flags of the source.
Tee is currently -f tee "[f=mp4:use_fifo=1]
I am hoping I can add flags too, I will have a look about I am sure I will find 
something online.

That will not resolve 3rd party files but at least I will be producing media 
encoded as intended :)

thanks
Adam

What's wrong with using qtfaststart on them (or on all files)?

The problem is that the platform running ffmpeg is a container that can 
accesses the source media stored in s3 object storage through the aws command 
line stream copy. This enables FFmpeg to start transcoding immediately from any 
S3 bucket it has the account details for.
I presumed that the qtfaststart running on the same platform would also run 
into the problem with the source only being accessible through the aws command 
line.

Testing using…

aws s3 cp s3://storage/source/abc-6a-test_mov_34_1588580170874.mov - --quiet | 
qt-faststart - /data/temporary/transcode_20200505-993-j7flu0/testqtfaststart.mov

was unsuccessful and resulted in -: No such file or directory.

So if I am going to need to localise the file to use qt-faststart I might as 
well go straight to ffmpeg transcode.
Thanks for your help, I have learnt about a new tool which looks really useful 
for batch fixing archive mp4 for example.

Thanks
Adam

[FFmpeg-user] Error while playing record audio from webcam

[Vijay Rakesh Munganda]

Hi All, 

I’m using below command to create video and audio files for real time streaming 
to the cloud.

ffmpeg -f alsa -channels 1 -thread_queue_size 1024 -i hw:1 -f video4linux2 -i 
/dev/video0 -c:a aac -ar 48k -t 0:10 -segment_time 00:00.08 -f stream_segment

When I use ffplay on video clips it is playing, but when I run audio clips I 
get different errors for different segmented output as follows, and some clips 
play for more than 13s when segment given as 80ms. 

Error:

[FFmpeg-user] Error decoding RTSP stream using h264_cuvid vcodec

[Nishant Trivedi via ffmpeg-user]

Hello,

I am trying to decode a RTSP video stream using ffmpeg while using
h264_cuvid vcodec to take advantage of hardware acceleration on a machine
with NVIDIA GPU. I am seeing an error with the message Unknown encoder
'h264_cuvid'. I've made sure that I compiled ffmpeg with cuvid enabled.
Here is the output of "ffmpeg -version" command:
$ ffmpeg -version

libswresample   3.  3.100 /  3.  3.100

To rule out problems with the stream, I checked it using ffplay and I'm
able to visualize it. But when I run the following command
ffmpeg -rtsp_transport tcp -hide_banner -loglevel debug -stimeout 100
-rtsp_flags prefer_tcp -allowed_media_types video -i
rtsp:///onvif/profile1/media.smp -vsync 0 -err_detect explode
-surfaces 8 -vcodec h264_cuvid output.avi
I consistently get the encoder error. Removing the vcodec argument works
but I lose out on hardware acceleration. I'm attaching the full debug
output of the ffmpeg command herewith.

I dug around for possible resolutions but didn't find anything meaningful.
Appreciate any help on this.

Thanks,
- Nishant.

[FFmpeg-user] Error Message: sps_id 1 out of range

[Simone Croci]

Hi All,

I am decoding an MVC H.264 video and I get a lot of error messages "sps_id
1 out of range". What is the problem? is it caused by the fact that ffmpeg
does not support MVC H.264?

Simon

When I cut the sample file down to 10 MB in size, it stops playing with 
ffplay and it's not reproducable. However, if I cut it down to 20 MB, 
the same error as previously described appears. According to 
https://www.ffmpeg.org/bugreports.html, you don't want samples larger 
than 10 MB.


The 10 MB sample gets stuck demuxing with:
[matroska,webm @ 0x7fab58c0] Read error

(Full, uncut output of ffplay: http://pastebin.com/ChEq2YZB)
(ffmpeg has the same output as before basically)

This is unsurprisng given than it's an HD (Bluray quality) file and 10 
MB isn't enough to seek. What this does suggest is that ffplay is 
somehow looking ahead into the second ten megabytes in order to 
determine the file parameters and FFplay isn't.


Should I make an exception and upload the 20 MB file instead?

To confim your assumption: Running ffmpeg and ffprobe with
"-analyzeduration 20M -probesize 20M" does seem to work:

  Duration: 00:01:30.05, start: 0.00, bitrate: 1819 kb/s
Stream #0:0(jpn): Video: h264 (High 10), yuv420p10le(tv, bt709), 1920x1080 
[SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc (default)

I get a read error after 5 seconds, probably because that's the length
you truncated the video to.

I opened ticket #4725, thank you for the sample!

The size limit of course assumes that the length 
is sufficient to reproduce the original issue, a 
10G sample was uploaded once because nobody knew 
how to reproduce with a smaller sample.

I'm not sure how that patch is related to your error message which is
about ffmpeg.c.  Anyway, I think your problem was fixed in this commit

I assume it was after 2.7.2.  Use the latest git head and you should not
get that error.

Could it be that you are including *.libs that are built with VS2013 or
earlier? They cannot be mixed.

This led to a similar error stating snprintf, vsprintf etc. are not

[FFmpeg-user] ERROR: opus not found using pkg-config

[Ashutosh Kumar]

Hi,
 I am getting error on ff-mpeg installing time.


ERROR: opus not found using pkg-config

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ff-mpeg-u...@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.

Which gets some (limited) support on Linux, but not on Windows.
(Why would a Windows user install a version of FFmpeg that is
known to contain more bugs and less features but for which he will
not get any support?)

they also claimed that ffmpeg is dead and the ffmpeg cli command is 
deprecated - the only reason why they claim something is because their 
fork failed and they pretend it is still vital

since there are no official binaries at all and on a typical windows

This indicates that either you don't feed the input data into the demuxer
or that your libavformat version is old.

Note that (as you can see from the console output you posted)
that your input is not mjpeg format.

[FFmpeg-user] Error Encoding AAC to HLS Using ffmpeg

[Ashish Jha]

I want to encode an AAC formatted audio file into multi bitrate HLS using 
ffmpeg:


fmpeg -re -i input.aac -b:a:0 128k -af volume=6dB -ar 48000 -hls_time 20 -vn 
-hls_list_size 0 -b:a:1 256k -af volume=6dB -ar 48000  -hls_time 20 -vn 
-hls_list_size 0 -map 0:a -map 0:a -f hls -var_stream_map 
"a:0,agroup:aud_low a:1,agroup:aud_high" -master_pl_name index.m3u8 
index_%v.m3u8

This lets me get 1 master manifest and 2 child manifests, which are playable on 
android. However, this does not play on desktop using chrome. I found these 2 
lines in master manifest that seem to cause the issue. When manually removed, 
it plays perfectly.


#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="group_aud_low",NAME="audio_0",DEFAULT=YES,URI="master0.m3u8"
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="group_aud_high",NAME="audio_1",DEFAULT=YES,URI="master1.m3u8"

Is there a way to encode audio in multibitrate that avoids this issue?

I couldn't find the file /etc but could locate the ffserver.conf in

I copied it from ~/ffmpeg_sources/ffmpeg/doc to /etc
But I am not sure if this was the right thing to do.

uhm read some manpages

you need to configure it for *your needs*
that's why it is a config file

That was definitely NOT the right thing to do. You should never use the root
privileges lightly.

The right thing to do is to read the documentation. FFserver's documentation
is available online:

http://ffmpeg.org/ffserver.html

And you also have a copy of the same documentation in the doc/ directory in
the compilation tree.

The documentation is quite long, but there is a nice table of contents in
the HTML version, and the title "3.3 How do I make it work?" looks
promising.

well, that is what the error message says in your first post

you don't want that file to be installed automatically
or do you wan't to get your config overwritten with updates

/etc is not a file
/etc is the folder with configurations on unix

~/ffmpeg_sources/ffmpeg/doc
I copied it from ~/ffmpeg_sources/ffmpeg/doc to /etc
But I am not sure if this was the right thing to do.

[FFmpeg-user] Error with parameterization using h264 with profiles

[S. John]

Hi everybody!

I'm struggling with a simple task. Converting an .avi containing a 
single cvid

video stream with rgb24 color model to a .mp4 with h264 encoding.

For some reason, ffmpeg won't let me use any other h264 profile other than
high444. With every other profile i use, the encoder still seems to use 
yuv444p

pixel format (which is only allowed in high444). Doing so /
 ffmpeg -i input.avi -vcodec libx264 -vprofile main -pix_fmt yuv420p 
out.mp4/

results in an error:

Output #0, mp4, to 'out.mp4':
Stream #0:0: Video: h264, yuv444p, 320x240, q=-1--1, 90k tbn, 15 tbc
Stream mapping:
  Stream #0:0 -> #0:0 (cinepak -> libx264)
/Error while opening encoder for output stream #0:0 - maybe incorrect
parameters such as bit_rate, rate, width o//r height/

I can circumvent the problem by manually specifying the correct pixel 
format:
/ffmpeg -i input.avi -vcodec libx264 -vprofile main -pix_fmt yuv420p 
out.mp4/


Is this an intended behavior? For what I read in the documentation, I 
expected
ffmpeg to automatically choose parameters in accordance to the selected 
profile.
Or is the profile selection more like an assert, just telling me 
whenever I'm not

in accordance with the constraints of a selected profile?

Thank you for any information on this topic!

I have run again the command after restarting the computer, and I haven't
seen any error message this time.

This is the error message I got the first time I run the command:

[h264 @ 0153dc5d4280] sps_id 1 out of range


Apparently, the problem has been solved by simply rebooting the PC. Btw, my
OS is Windows 10.

Does the error disappear if you don't use "-s" if you are using "filter_complex"
(as you have to)?

"-f mpegts" looks strange in this command line (but that may only be me).

[FFmpeg-user] ERROR: libvmaf >= 2.0.0 not found using pkg-config

[桃源老師]

Hello,

I experienced funny ffmpeg compille error "ERROR: libvmaf >= 2.0.0 not found 
using pkg-config".  The reason why I feel funny is that ffmpeg commit of 
"06a54a4ec73ea6eb8cec41b7af75367bafb075e0(Date: Sat Jan 22 10:32:34 2022 
+0100)" can configure and make correctly, but current git head can't configure. 
 I suppose something wrong was happened after 2022/01/22.

I'm trying to build ffmpeg on macOS 12.2.

The seems to error portion on config.log is:

/var/folders/1d/qk_hczkn68xfv_7gdbkmhwx4gn/T//ffconf.DmkkrFIx/test.c:3:44: 
error: use of undeclared identifier 'vmaf_init'
long check_vmaf_init(void) { return (long) vmaf_init; }
   ^
1 error generated.
ERROR: libvmaf >= 2.0.0 not found using pkg-config


Any help is appreciated...

The Chapter 5 file dts-hd-ma have certain delay. Thus you get with ffmpeg
first few frames in only dts core at 48kHz 16bit and later full dts-hd-ma
kicks in
with 192kHz and 32bit, but because filtering is not supporting changing of
sample rate and/or sample format at runtime all remaining frames are
filtered
back to 48kHz and 16bit. This is evident if you run ffmpeg with '-v debug'
flag.

Workaround is to force filtering at 192kHz and 32bit right at start with
this command:

ffmpeg -i Title1\ -\ Chapter\ 05.dts -af aformat=f=s32p:r=192000:cl=stereo
out.flac

Hardware playback of 24bit flac at 192000 Hz is not widely supported AFAIK.

Re: [FFmpeg-user] Error decoding DTS-HD MA audio files

[rfischer56]

Thanks, Paul
You are a genius. Your command worked with the two files I had sent you. I am 
now getting playback on the dCS Rossini from the beginning and (as far as I can 
hear) gapless playback between 4 and 5.
However, I still have an inkling that not all is well
I have attached the log of the two conversions that I did. Chapter 4 seems to 
convert ok with some messages but (as I see it) nothing serious. However 
Chapter 5 (the one that previously converted to 48kHz) has some serious error 
messages. Playback of the flac file seems ok.
The dts file was extracted from the BluRay using DVDAE and the 'direct stream 
demux' option.  Ffmpeg has more issues with some extracted "dts files than with 
others. Could it be that the issue is already at the stage of the 'direct 
stream demux' option?
As I am getting exactly the same results (same files extract @48kHz) using 
MakeMKV / MMH, there could be a problem at the ripping stage of the BluRay and 
not primarily with ffmpeg? What do you think?
Best regards
Rudi

I do not think it is ripping stage. It is how content was originally
produced.
I also noticed some strange error at end of chapter 5. So to be 100% sure
it is still ok, check for gapless between chapter 5 and 6 (if there is 6
chapter or whatever comes next).
There is very slight chance that there is no delay in any of dts files but
I doubt that because decoder follows specification 100% AFAIK.

Re: [FFmpeg-user] Error decoding DTS-HD MA audio files

[rfischer56]

I have now ripped the whole Vol 1 of the first BluRay (87 tracks) with the 
'direct stream demux' method and then converted to flac with ffmpeg using your 
command parameters. The resulting flac files play ok. Most transitions are 
perfectly gapless, but there are a few that have a slight click at the track 
change (amongst others between 5 and 6).

Next, I tested playback with my Oppo BDP93 via HDMI to an Onkyo AVR. 
Interesting result. Playback is @192kHz and gapless. However when I skip to 
tracks 5 and 6 (who both showed issues when converting to flac), the Oppo 
counter increments (showing playback in progress), but output stays silent. If 
I play tracks 4, 5 and 6 in one go without skipping forward, playback is ok and 
gapless. So there definitely seems to be a production issue on DG's side.

Your workaround is priceless, thank you. I will now get back to Deutsche 
Grammophon to see if I can get the 192kHz files as a download from them
Best regards
Rudi

[FFmpeg-user] Error with FFmpeg and Node Canvas for SubtitleO

[Suraj Kadam]

We have a subtitles automation tool, made on ReactJS on FE. and NestJS on
BE.

So the flow is that on the frontend first we show the user a preview of the
subtitles, and give him options to modify the styling, the position of the
subtitles or the subtitle container, and on the preview everything is done
using CSS and JS.

We are looking for a sync up between the values from the frontend to apply
accurately on the backend.

Our current approach is by generating PNG images using node-canvas and then
streaming them out on the video at particular timestamps using
overlay_filter.

The first concern is of the scaling or the dimensions, as on the frontend
we are using VideoJS, and of course for better view we are resizing the
container as per devices etc, so the video's width & height on the frontend
is less (mostly) than the actual dimensions of the video.

While using that dimensions, the subtitles are too short to be rendered on
the video (smaller) as the width and height of the canvas gets shorter.

And also for the position, we are using react-draggble library for making
the subtitles draggable and place them on video In the preview, still we
lack on syncing up both the positions on the backend.

We are just looking for a proper roadmap or solution for these blockers.

Would appreciate your help on this.

Thanks.

Here's the current implementation of the code:

wrapText(context, text, x, y, maxWidth, lineHeight) {
const words = text.split(' ');
let line = '';

for (let n = 0; n < words.length; n++) {
  const testLine = line + words[n] + ' ';
  const metrics = context.measureText(testLine);
  const testWidth = metrics.width;
  if (testWidth > maxWidth && n > 0) {
context.fillText(line, x, y);
line = words[n] + ' ';
y += lineHeight;
  } else {
line = testLine;
  }
}
context.fillText(line, x, y);
  }
  generateSubtitlePNG(transcription: any, outputPath: string, w, h) {
const canvas = createCanvas(720, 200);
const ctx = canvas.getContext('2d');

ctx.fillStyle = 'rgba(0, 0, 0, 0)';
ctx.fillRect(0, 0, canvas.width, canvas.height);

const fontSize = 41;
ctx.font = `bold ${fontSize}px Arial`;
ctx.fillStyle = 'white';
ctx.textAlign = 'center';

const maxWidth = canvas.width; // 20 pixels padding on each side
const lineHeight = fontSize * 1.4; // Adjust as needed
const x = canvas.width / 2;
const y = (canvas.height - lineHeight) / 2 + fontSize / 2; // Adjusted
for font height

this.wrapText(ctx, transcription.text, x, y, maxWidth, lineHeight);

const buffer = canvas.toBuffer('image/png');
fs.writeFileSync(outputPath, buffer);
  }

  const outputPath =

  this.generateSubtitlePNG(
transcriptions[i],
outputPath,
dimensions?.width,
dimensions?.height,
  );
  pngPaths.push(outputPath);
}
let filterComplex = '[0:v]';

I've built the latest Git build of aom with cmake and default settings. I don't 
know what's wrong. But from the looks of it, this might be a bug in libavcodec, 
since the corresponding function in libaom that's throwing the error takes 5 
arguments instead of 4.

I'd appreciate if somebody could help me with this.

hi all:
  I compile FFmpeg which support x265 by these steps:


sudo apt-get install mercurial cmake cmake-curses-gui build-essential

hg clone https://bitbucket.org/multicoreware/x265
cd x265
hg checkout 0.8
cd x265/build/linux

That's because no such encoder exists.

Have you tried "h264_nvenc"?

On this list, it's also always a good idea to use a recent version of
ffmpeg - preferred from latest git. That way, you can rule reporting
bugs or missing features which are no longer valid.

[Nishant Trivedi via ffmpeg-user]

Oh duh! Thanks @Moritz!

As a side note, I just wanted to mention that we mostly deal with RTMP
streams and we have been starting the ffmpeg process the way I described
for over a year and half now and it never complained. It's just now that we
started looking into supporting RTSP, ffmpeg complained about the option.
Obviously it's a bug on our end and we will fix the arg but I thought it
would be interesting to note the behaviour here. Thanks again!

Best,
- Nishant.

Hmm, I don't think an "h264_cuvid" encoder has ever existed - only a
decoder. (There was some cleanup recently in those aliases, but I
cannot identify such an encoder having being removed.) Perhaps you are
confusing the two?

No problem, as long as your encoding works again now.

Apologies, I didn't mean to say that the encoder existed. I was just
pointing out that ffmpeg didn't complain about the wrong argument. And when
I say ffmpeg, I actually mean ffmpeg-python which is what we use to
interact with ffmpeg. I also realize that ffmpeg-python may not fall in
your purview at all. Just making an observation.

Best,

Your ffmpeg configure line is blank. From subtitle filter documentation:

  "To enable compilation of this filter you need to configure FFmpeg
  with --enable-libass."

See:
http://ffmpeg.org/ffmpeg-filters.html#subtitles

The ass filter also depends on libass.

Dear Lou-2
Thanks  for the advice. I uninstalled ffmpeg and then reinstalled ffmpeg
following the instructions on
https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu  so that i can "configure
FFmpeg   with --enable-libass."  as you advised.  Unfortunately, I still
get the same message.

I can't figure out what changed during my reinstall of ubuntustudio and
ffmpeg that caused this problem.

If you had passed any arguments to ./configure when building, they
would be shown here, approximately as:

I believe you're still using the same ffmpeg binary as before.

Thanks Moritz.

I'd appreciate a tip where to find a suitable ffmpeg. I am using

If you compile ffmpeg, you may add libass to the binary. See this page 
on how to compile:


https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu

Hi Daniel, thanks for the reply. This is exactly what I did. But I still
get the error. I am beginning to suspect that it is not the binary but in a
saved configuration somewhere that I need to delete. Any tip how to do it?

The guide places the compiled ffmpeg binary in ~/bin. One reason
for this is to avoid interfering with system files, the repository
packages, and the package management system. ~/bin is automatically in
the vanilla Ubuntu PATH, but only if the directory already exists.

As the guide mentions, either log-off and log-in, or run ". ~/.profile"
for your shell to notice. You'll only need to do this once.

Alternatively, move the ffmpeg binary in your preferred location in
your PATH.

Thanks Lou. Yes, I did log out and logged in again. I followed the

it did not.

I don't know why it's not working for you, and I don't want to try to
debug every possibility, but perhaps you would find it easier to use a
PPA:

https://launchpad.net/~mc3man/+archive/trusty-media

Or you could upgrade your distro. FFmpeg returned to Ubuntu in 15.04
and it is available in the repository, and I assume it has libass
support.

[jun]

Sorry about that. I had to google what top posting is. I hope this is
better. Otherwise you have to patiently guide me through this top posting
bit

When I reinstalled ubuntustudio, I kept my old home directory, so I figure,
some of the changes that I did while installing other stuff could have
affected the behavior of ffmpeg.

I suspect that the problem lies not in ffmpeg, nor in ubuntu studio. It
maybe something that I installed or uninstalled along the way. I think I
will backup my data on another disk, then reinstall and have a clean home
directory...

I am new at this, but this old dog is ok with learning new tricks.

thanks for the patients, Lou and others

[FFmpeg-user] Error while generating images from video through network

[Gururaj Nayak]

Dear Team,
   I am using  ffmpeg.exe for  converting  video into images and   getting

times  images (frames)  getting  skipped while extracting  it from video (which 
is at network ) . The  same  is working  fine  wherever I am copying  the  
video on local machine and  then trying  to convert it  from  the  exe.  Please 
suggest at your  end.

Do you have the libass development package ("libass-dev" or
"libass-devel") installed? It would be the one providing the missing
libass.pc.

Your exact command line works fine here, please test the following:
$ ffmpeg -i /dev/video0 -pix_fmt yuv420p out.mov

Unrelated:
Note that "-r 30" in your command line looks like a bad idea, 
you should probably remove it and h264 in avi can lead to 
unexpected issues.
