[FFmpeg-user] Extracting first subtitle as an image
Is there an easy way to extract the first subtitle (dvdsub) for a specific stream as an image? In such a way that I can see the subtitle in the resulting image. The following works... (limited testing) but it's kind of slow and cumbersome and I'm hoping there's a better way: $ ffprobe -i movie.vob -select_streams 5 -show_frames -print_format flat | grep 'pts_time=' | head -n1 (get the value of pts_time from output and use in -ss option) $ ffmpeg -i movie.vob -ss 209.883889 -codec:v mpeg2video -filter_complex '[0:v][0:5]overlay' -frames:v 1 -f mpeg - | ffmpeg -i - -frames:v 1 subtitle-05.png I don't care if the subtitle is overlayed onto the video, all I want is to see the subtitle. In fact I'd prefer it was NOT overlayed... or if it has to be overlayed, could it be overlayed onto some kind of blank background? ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
[FFmpeg-user] Fwd: VBV Underflow errors while setting up a desktop stream on OS X
Hi, I've setup a desktop stream using the following ffmpeg parameters. I stream the raw data to an ffserver instance running on the same machine (OS X Yosemite). The ffserver streams encoded video to another machine on the same local network. I keep getting VBV Underflow errors on the desktop capture stream. I've changed the encoding parameters such as keyint, vbv-maxrate and vbv-bufsize on the ffserver conf to no avail.(We encode using libx264 ) The VBV underflow errors especially occur when there's a lot of movement on the screen. Can someone please take a look at my parameters and let me know if I'm doing something extremely wrong?

Re: [FFmpeg-user] example to use VDA hw decoder on mac with ffmpeg?
I cold emailed Xidorn who is the author of the h264_vda_dec.c file. this was the answer: Hi Shi, I'm not very surprised that the VDA decoder cannot be properly inited here. I guess you probably eventually have to remux your video to use MP4 or MKV container. I don't know exactly what happens there, but according to my experience playing with VDA framework before, that framework had quite a few limitations. I guess the limitation you met might be that, it required some extra data of the video to init the decoder, which made it support only some of the containers. I forget what the exact name of that extra data, but AFAIK, only MP4-compatible container could provide that. Regards, Xidorn I quickly tried a mp4 file, which worked. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
[FFmpeg-user] Issue with using amerge & pan to map & mix
I am trying to utilize the amerge & pan filters to combine the audio tracks of an MXF & MOV to create a 10 channel mix from them. I am trying to mix both channels from the stereo WAV to output channels 3 & 4, if I do this, I get silent audio on the output. If I map the inputs and apply no mixing, I get audio output. If I just mix Stereo WAV's input channels to two channel WAV, that results in a file with audio. It only seems to be that when I combine mapping and mixing, I get no audio output. ffmpeg D:\MIX\VIDEO.mxf -i D:\MIX\Stereo_AUDIO.wav -filter_complex "[0:1][0:2][1:0]amerge=inputs=3,pan=10c|c0=c0|c1=c1|c2 amerge:in0 Stream #0:2 (pcm_s24le) -> amerge:in1 Stream #1:0 (pcm_s24le) -> amerge:in2 pan -> Stream #0:0 (pcm_s24le) Press [q] to stop, [?] for help [pcm_s24le @ 04eabde0] not writing 'chan' tag due to lack of channel information size= 2067347kB time=00:24:30.10 bitrate=11520.1kbits/s video:0kB audio:2067331kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.000787% Image of the audio waveform with silence on all 10 channels: http://imgur.com/JpafflT If I modify the command to not mix the audio I get all the audio channels. ffmpeg -i D:\MIX\VIDEO.mxf -i D:\MIX\Stereo_AUDIO.wav -filter_complex "[0:1][0:2][1:0]amerge=inputs=3,pan=10c|c0=c0|c1=c1|c2=c16|c3=c17|c4=c4|c5=c5|c6=c6|c7=c7|c8=c8|c9=c9[a1]" -map "[a1]" -acodec pcm_s24le -timecode 00:59:45;02 D:\MIX\VIDEO_audio_only_no_mix.mov Image of the audio waveform with audio on all 10 channels: http://imgur.com/8Bc0b1K I decided to just test taking the stereo audio file and mixing the audio to mono.

Hi, I've been cropping a number of mp4 videos with ffmpeg but I was just wondering whether there is a way of doing it that doesn't involve re-encoding. I've been using a command like: ffmpeg -i "Gopro1.mp4" -filter:v crop=iw-300-20:ih-0-180:300:0 "Gopro1_crop.mp4" Which works by cropping a 1920 x 1080 video to 1600 x 900 But just wondering if there is a quicker way.

This seems to have fixed the output. I should probably learn to read the

However, the Raspberry Pi that is looking for the output (listening with
pwomxplayer for a video wall) does not receive anything when using this
command, unless I specifically set the video codec to h264 (-c:v libx264),
this brings new problems with it, creating a lot of "Past duration
0. too large" errors or just flatout crashing. I understand if I now
need to go and look for answers from the pwomxplayer side of things, but the
Pi does actually pick up the output with this command, so just need to make
sure that ffmpeg can handle the transcoding I guess!

but it's hard to tell whether this reports an ffmpeg segmentation
fault. (What is Videokit?).
Your command line:
> ffmpeg -i /sdcard/perfect.mp3 -i /sdcard/output_subtitle.mp4 -acodec -vcodec
> copy /sdcard/newvideo.mp4
has an error, you don't provide an audio codec after '-acodec'. ffmpeg
tells you so:

It is interpreting "-vcodec" as your audio codec.
> 03-18 19:01:31.501: D/Videokit(10092): Opening an output file: copy.
And "copy" as a file name.
You need to fix your command line to be:
> ffmpeg -i /sdcard/perfect.mp3 -i /sdcard/output_subtitle.mp4 -acodec copy
> -vcodec copy /sdcard/newvideo.mp4
for example.

Have you tried following this hint? Taken from your output log:

[FFmpeg-user] RTMP Input error (UDP output)
I am trying to use an RTMP source from the internet and broadcast it to my
local network over UDP.
In the console output below I am using avi as my file format which produces
the error.
If I use flv, there is no error and output SEEMS to be ok but I cannot
receive the output through pwomxplayer on a Raspberry Pi.
Any help is greatly appreciated!

[FFmpeg-user] How to set 3 specific metadata flags (ITU601/displayoffset) in FFmpegs IMX50 MXF-OP1a encoding?
Hello I am testing with ffmpeg the IMX50 D10 encoding, and I am very close to my target but I have to create 3 metadata values in the MXF header which is standard in most IMX50 MXF ecndodings: + SIGNAL STANDARD = 1 (ITU 601) + display y offset = 32 - I am encoding 720x608 sources with included VBI area (32 lines high at the top) -> the offset 32 defines the active picture -> 720x576 + Color siting = 4 (Rec 601) Is it possible to encoded with ffmpeg in a way that these values can be written? If yes, which syntax should I add to my used syntax? If no, could the option be implemented in future? My used ffmpeg syntax is: ffmpeg -i -map 0:v -map 0:a -c:v mpeg2video -r 25 -pix_fmt yuv422p -aspect 4:3 -minrate 5k -maxrate 5k -b:v 5k -intra -flags +ildct+ilme+low_delay -intra_vlc 1 -non_linear_quant 1 -ps 1 -qmin 1 -qmax 3 -top 1 -dc 10 -bufsize 200 -rc_init_occupancy 200 -rc_buf_aggressivity 0.25 -tag:v mx5p -c:a pcm_s24le -ar 48000 -f mxf_d10 I check the MXF metadata with BMX mxf2raw.exe (BBC) I use 2 examples: 1.) a ffmpeg encoded MXF and 2.) a MXF from the Carbon Coder (Rhozet). The carbon Coder playout shows me the wanted values: C:\Users\gersti>mxf2raw -i I:\IMX_tests\IMX50_CARBON.mxf MXF File Information: Filename : I:\IMX_tests\IMX50_CARBON.mxf MXF version: 1.2 OP label : OP-1A (internal essence, stream file, multi-track) Wrapping type : Frame Material package name : Material start timecode: 00:00:00:00 (@ 25fps) File src start timecode: 00:00:00:00 (@ 25fps) Edit rate : 25/1 Precharge : 0 Duration : 500 Rollout: 0 Identifications: Identification 0: Generation UID: 10e5dae5.54663246.8c411484.8c2015e4 Company name : Rhozet Product name : Carbon Product version : (not set) Version string: 1.1 Product UID : 842d0e07.eb104da4.b6d1c16b.bfdf797b Modification date : 2015-02-03 13:39:02.000 Toolkit version : (not set) Platform : (not set) Track 0: Essence kind : Picture Essence type : D10 50Mbps Essence label: 060e2b34.04010101.0d010301.02010101 Material package uid : 060a2b34.01010105.01010d20.1300.d403bb57.8f86e749.9a0e3118.abce6ab9 Material track id: 2 Material track number: 0 File package uid : 060a2b34.01010105.01010d20.1300.09464eb5.53deb944.9566c38d.b95db9fd File track id: 2 File track number: 0x05010100 Edit rate: 25/1 Duration : 500 Lead filler offset : 0 Picture coding label : 060e2b34.04010101.04010202.01020101 Signal standard : 1 (ITU 601) Frame layout : 1 (Separate Fields) Stored dimensions: 720x608 Display dimensions : 720x576 Display x offset : 0 Display y offset : 32 Aspect ratio : 4/3 AFD : (not set) Component depth : 8 Horiz subsampling: 2 Vert subsampling : 1 Color siting : 4 (Rec 601) The FFMPEG MXF looks like this (the 3 values are not set correctly): C:\Users\gersti>mxf2raw -i I:\IMX_tests\IMX50_FFMPEG.mxf MXF File Information: Filename : I:\IMX_tests\IMX50_FFMPEG.mxf MXF version: 1.2 OP label : OP-1A (internal essence, stream file, multi-track) Wrapping type : Frame Material package name : Material start timecode: 10:00:00:00 (@ 25fps) File src start timecode: 10:00:00:00 (@ 25fps) Edit rate : 25/1 Precharge : 0 Duration : 750 Rollout: 0 Identifications: Identification 0: Generation UID: adab4424.2f254dc7.92ff29bd.000b0001 Company name : FFmpeg Product name : OP1a Muxer Product version : (not set) Version string: 55.48.101 Product UID : adab4424.2f254dc7.92ff29bd.000b0002 Modification date : 0-00-00 00:00:00.000 Toolkit version : (not set) Platform : (not set) Track 0: Essence kind : Picture Essence type : picture essence Essence label: 060e2b34.04010102.0d010301.02046001 Material package uid : 060a2b34.01010105.01010d00.1387b014.52947134.7187b014.00529471.34718700 Material track id: 2 Material track number: 0 File package uid : 060a2b34.01010105.01010d00.1387b014.52947134.7187b014.00529471.34718701 File track id: 2 File track number: 0x15010500 Edit rate: 25/1 Duration : 750 Lead filler offset : 0 Picture coding label : 060e2b34.04010103.04010202.01020200 Signal standard : 0 (None) Frame layout : 1 (Separate Fields) Stored dimensions: 720x608 Display dimensions
