I'm having a similar problem. This is the call I'm using:
ffmpeg -y -r 30 -i titleCard.mp4 -i rawRecording.mp4 -i credits.mp4 -i longSong.mp3 -filter_complex "[0:0][0:1][1:0][1:1][2:0][2:1] concat=n=3:v=1:a=1 [concatv] [concata], [3:0]aformat=sample_fmts=fltp:sample_rates=48000:channel_layouts=stereo,volume=0.4[quiet], [concata][quiet]amerge=inputs=2[aout]" -map [concatv] -map [aout] -pix_fmt yuv420p -c:a aac -strict -2 output.mp4 I've tested this on a bunch of platforms, and I've found that it plays back with no issues on Windows Media Player and the new Windows 10 Movies & TV app (of all things), but not in Chrome, Quicktime, VLC, etc. What platform are you trying to play your output file back on? I'd be curious to see if it plays with no sync issues on any platform. -- View this message in context: http://ffmpeg-users.933282.n4.nabble.com/Sync-video-and-audio-after-using-complex-filters-to-blend-two-files-tp4678487p4678596.html Sent from the FFmpeg-users mailing list archive at Nabble.com. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
