ffmpeg problem again

[loa909]

I did post here before and got briliant help but cant seem to find last post so made a new post

I have this script for making movie clips louder. but just tried a short clip and get this error, would anyone know why this is the error below. it seems to be something about timestamp

and this is the audio script

  @setlocal

@echo Audio processing, video is copied losslesly

@rem folder where ffmpeg.exe is located
@set FF=C:\ffmpeg-3.4-win64-static\bin

Also I have another error on another movie clip too

You can add '-fflags +genpts' to command line but not sure if this will work and solve issue with your source.

@ffmpeg.exe -hide_banner -v 32 -stats -y -fflags +genpts -i "%filename%" -c:v copy -af %aproc% -c:a aac -b:a %ab%k -f matroska "%~n1_dynaudio.mkv"

Not sure if this is not an issue related to codec and container then this filter may be necessary https://ffmpeg.org/ffmpeg-bitstream-filters.html#mpeg4_005funpack_005fbframes - some of bitstream filters are invoked automatically if necessary, not sure how with this case.

[loa909]

well it seems to have fixed it thanks again


Where would I need to place this line in the script anyway

ffmpeg -i INPUT.avi -codec copy -bsf:v mpeg4_unpack_bframes OUTPUT.avi

this bitstream filter can be placed after input and before output however not sure if AVI is a good container for it (main purpose of this filter is to unpack frames packed for AVI container due of AVI container limitations). Honestly i don't recall this kind of problems from XVid/Divx files...
