Ancient and unsupported. See:

You did not include your actual command. Without that information it is
impossible to know what your did and therefore impossible to provide any

[FFmpeg-user] Comparing keyframes of videos for proper alignment

[Joel Lopez]

Hi,

I'm trying to verify that the keyframes of videos we are using are properly
aligned.  I've found ffprobe to extract the some info but I'm not sure what
data I should be comparing.

This is so that we can do some adaptive bitrate switching using an SMIL
file for RTMP, HLS and eventually MPEG-DASH.  I've been reading that they
keyframes should be a constant 3 seconds apart.  Hopefully someone has some
experience in this.

Re: [FFmpeg-user] Broken installation after OSX update

It's fixed.  My homebrew was also broken after the update.  I got that
working then reinstalled ffmpeg and all is well.

Thanks for the help.

-bash: ./usr/local/bin/ffmpeg: No such file or directory



But I decided to investigate

lrwxr-xr-x  1 jlopez  admin  31 Apr 18  2013 /usr/local/bin/ffmpeg ->
../Cellar/ffmpeg/1.2/bin/ffmpeg



When I look in Cellar ffmpeg isn't in there anymore.

jlo-MacBook-Pro:Cellar jlopez$ ls

openssl wget


I suspect I had a homebrew install and homebrew broke too.

Please do not reply to another user's thread with questions involving an
unrelated topic (I am assuming you are not also Joel Lopez). This is
called "thread hijacking" and causes confusion.

Also, try to avoid top-posting; it is discouraged here.

ffmpeg-php, or at least the iteration you are using, is a long dead
project. You will likely not get help for that anywhere.

You need to decide if you even need a PHP wrapper for ffmpeg. You could
possibly just execute the binary from your script. See:
http://trac.ffmpeg.org/wiki/PHP

I did not look at your PHP script because we do not provide support for
scripts here. We can only provide support for unscripted commands for
the various FFmpeg cli tools.

If you manually run your ffmpeg command in a console, and you have an
issue, we can probably help with that. If the ffmpeg cli command works,
and the problem is with your script we can't provide help for that and
you would need to go to a PHP help resource.

you write a lot of text with no content

[FFmpeg-user] Broken installation after OSX update

[Joel Lopez]

I seem to have broken my ffmpeg install on OSX after an update.  But I
can't remember if I compiled it or used homebrew to install it.  How can
uninstall and reinstall or repair it?  Does it matter how it's removed?


I now see this when I run the command:

jlo-MacBook-Pro:~ jlopez$ ffmpeg -i

-bash: ffmpeg: command not found


If I run a locate ffmpeg I see it's in there:

jlo-MacBook-Pro:~ jlopez$ locate ffmpeg

[FFmpeg-user] ffmpeg not working on server

[Waleed Afridi]

Hi

I am using ffmpeg for video conversion, i already configure it on my locale
server(WAMP) which work perfectly with shell_exec(escapeshellcmd(code));

For completed code PFA

When i online that on dedicated server(linux) with path (Path to the
binary: /usr/bin/ffmpeg )

It cannot convert video and also thumbnail, but generate empty video and
blank image

I already attached my locale(my locale setting.png) and
online(Makechange.tv library.PNG) library installed info
If my code is not correct for server than let me know the correct one.


Thanks

Re: [FFmpeg-user] difference in timing (instead of record duration in seconds) ...

Recording duration and time difference is the same thing to me, both
expressed by ffmpeg's "-t" option. (And avconf is not supported here,
wrong tool.)

So you want to specify the end point of time, _not_ the difference to
the beginning?

> >  How can you do that?

ffmpeg hase the "-to" option, which _should_ do the right thing. It
calculates the difference (which you would need to pass to "-t"
otherwise) itself.

$ ffmpeg -ss 00:05:30 -i input -to 01:15:20

(I - myself -  had a problem though: My impression was that the "-to"
option doesn't look at the file position (as "-ss" does), but rather at
the timestamp in the video stream or something else. And in my files,
that is often totally different. It would be so very practical for me
if it did work! I checked the source code though. It should work
correctly.)

No, that is time difference, and not what I think Albretch meant.

It generally doesn't / missing H264 timestamps are 
a known issue.

[FFmpeg-user] How to generate IRT conform D10 IMX50 MXFs (and how to set the output color_range, -space, -transfer and primaries flags)

[Christoph Gerstbauer]

Hello

I am making tests with IMX50/MXF encodings with FFMBC and FFMPEG. (with 
24bit audio)
The tests compare the final files with the IRT MXF Analyzer Pro tool to 
be shure to be IRT conform.

(My used syntax is at the bottom of this mail)

Both files (generated with ffmbc and ffmpeg) are working very well in 
editing tools but there is a little difference:


The IMX50 generated by ffmbc has no errors/warnings at IRT MXF Analyzer 
(with16bit audio). It is really perfect. In fact I never had a clean 
"green" MXF by testing other probes from other encoding tools. Only the 
IRT probes itself are clean. So this MXF is IRT conform when using the 
ffmbc standard target preset "imx50".


The Analyzis of the IMX50/MXF generated by FFMPEG (latest build from 
zeganoe) has 1 warning and 1 error:


WARNING:
"Fill Item Key with a wrong RP210 (SMPTE Metadata Dictionary) version 
number of 0x01. The correct version number is 0x02"


ERROR: "The Sound Essence Descriptor signals that the number if 
quantization bits is 24, which is higher than actually required (16) as 
detemined by parsing the essence."



Due to the fact that I am producing 24bit audio I could prevent the 
WARNING by producing 16bit audio. But is there a problem in the MXF when 
producing 24bit? Sound works in editing tools.
Furthermore ffmbc produces for standard a IMX with 16bit -> If I force 
ffmbc to do 24bit, I get the same error.


Due to the warning: I found out that both files are different regarding 
these values (by reading out via ffprobe - show_streams)


FFMBC IMX FILE stream 0:0:
color_range=tv
color_space=smpte170m
color_transfer=bt709
color_primaries=bt470bg


FFMPEG IMX FILE stream 0:0:
color_range=tv
color_space=unknown
color_transfer=unknown
color_primaries=unknown


So my questions are :

1.) How can I produce (with ffmpeg) the same output like ffmbc with 
these 4 metadata flags:

color_range=tv
color_space=smpte170m
color_transfer=bt709
color_primaries=bt470bg
I didnt found a answer to that in the ffmpeg documentation :/

2.) Maybe somebody knows: Do these 4 metadata flags have a connection to 
the Warning message of the MXF Analyzer? -> "Fill Item Key with a wrong 
RP210 (SMPTE Metadata Dictionary) version number of 0x01. The correct 
version number is 0x02"
If nobody know this answer I could do the test for myself by be able to 
encode with the upper params in 1.).


3.) Is there an syntax option in ffmpeg for 24bit audio encoding to 
prevent this ERROR:
"The Sound Essence Descriptor signals that the number if quantization 
bits is 24, which is higher than actually required (16) as detemined by 
parsing the essence."



Best Regards
Christoph
