Description of your issue, suggested solution and other information

Similar issue was disccussed here:
https://github.com/rg3/youtube-dl/issues/10719
...and was said to be fixed in FFMPEG 3.2

I have FFMPEG 3.4 and am seeing similar issues with twitter video.

The downloaded file plays correctly but I believe there is something incorrect with the time base that is being written, as if I try to do a post download transcode with FFMPEG the result is an audio drop at the point that of the "Non-Monotonous DTS" errors.

I realize this is more of an FFMPEG/59.94 tbc vs 29.97 fps issue...but if anyone has ideas idea on how to address these audio drop outs/timing issues, it would be much appreciated.

thanks as always
Ringo

The downloaded file plays correctly but I believe there is something incorrect with the time base that is being written, as if I try to do a post download transcode with FFMPEG the result is an audio drop at the point that of the "Non-Monotonous DTS" errors. I realize this is more of an FFMPEG/59.94 tbc vs 29.97 fps issue...but if anyone has ideas idea on how to address these audio drop outs/timing issues, it would be much appreciated. thanks as always Ringo

@glenn-slayden commented on GitHub (Sep 23, 2019):

This can be fixed by adding -vsync drop to the ffmpeg command line:

ffmpeg.exe -i "x.f244.webm" -i "x.f140.m4a" -vsync drop -c copy -map "0:v:0" -map "1:a:0" "x.temp.mkv"

Fortunately, the argument can easily be specified in youtube-dl via the --postprocessor-args option on the command line (or in the configuration file):

--postprocessor-args "-vsync drop"

This option should only be used for muxing into the .mkv container because it seems that specifying -vsync drop causes other sorts of failures (in av_interleaved_write_frame()) when muxing to .mp4.
