How to specify streams by pid with ffmpeg, If the value of pid is duplicated ?
22 novembre 2019, par Bo WangI have a nice m2ts file and I would like to demux specific audio streams from it. Of important, this specification is needed to use PID as identifier.
The exemplified m2ts file has 7 audio streams, which is detected by eac3to and shown beloweac3to.exe F:\xxx 1)
M2TS, 1 video track, 7 audio tracks, 5 subtitle tracks, 1:40:03

ffmpeg.exe -hide_banner -i "F:\xxx\BDMV\STREAM\00055.m2ts"
, ffmpeg shows an additional audio stream as it recognizes the embedded 5.1 AC3 stream inside the 7.1 TrueHD audio stream, as independent :Input #0, mpegts, from 'F:\xxx\BDMV\STREAM\00055.m2ts':

ffmpeg generate overlay complex filter for audio with background image
8 janvier 2016, par user1793606I am experimenting with ffmpeg and would like to generate overlay complex filter for audio with background image. The code normally works, except for when adding
-filter_complex "[0:a]showwaves=s=1280x720:mode=line,format=yuv420p[v]" -map "[v]" -map 0:a
it crashes. I found the example code at https://trac.ffmpeg.org/wiki/Waveform Any help is appreciated.Command '['c:/ffmpeg/bin\\ffmpeg.exe', '-y', '-loop', '1', '-r', '1', '-i', 'temp\\bg.png', '-i', 'test.mp3', '-filter_complex', '[0:a]showwaves=s=1280x720:mode=line,format=yuv420p[v]', '-map', '[v]', '-map', '0:a', '-c:v', 'libx264', '-preset', 'ultrafast', '-tune', 'stillimage', '-crf', '15', '-pix_fmt', 'yuv420p', '-strict', 'experimental', '-c:a', 'aac', '-b:a', '256k', '-shortest', '-threads', '0', 'done/test.mp4']'
EDIT 1 :
I tested this with the new verson :
ffmpeg -y -i input.mp3 -i background.png -filter_complex "[0:a]showwaves=s=1280x720:mode=line,format=yuv420p[v]" -map "[v]" -map 0:a -c:v libx264 -c:a copy output.mp4
It generates an output file, but only the waveform, no background included. My end goal is to generate the waveform over the background.
