youtube_dl.postprocessor.ffmpeg.FFmpegPostProcessorError: Conversion failed! #2

Closed pprw closed 3 years ago

pprw commented 3 years ago

On debian stable, I have this error at the last step of the process. I don't have it on another system running debian unstable.

Please run bbb-dl with the option -v so we get more debug information.

Which version of bbb-dl are you using?

pprw commented 3 years ago

Thank for the quick answer.

I am running bbb-dl 0.4 (installed today)

$ bbb-dl --version
bbb-dl 0.4

Here is the complete log (without url for privacy reason), files are already there from previous attempt:

can you try to run ffmpeg -y -loglevel repeat+info -i file:67a939c6406c54e348dc9ede72f48303a1fbe255-1610988048301/webcams.webm -i file:67a939c6406c54e348dc9ede72f48303a1fbe255-1610988048301/slideshow.mp4 -map 0:a -c:a copy -map 1:v -c:v copy -shortest 'file:2021-01-18T17-40-48_Séminaire Strasbourgeois.mp4'

In the same folder, so maybe we get a more detailed report from ffmpeg what is missing.

Interesting, seems that in the old version of FFmepg, copying opus to mp4 was still experimental. I use ffmpeg version n4.3.1, so I did not notice that. We could either put -strict -2 in the command or delete -c:a copy from the command.

Yes. This is why it was working on debian unstable with more recent version of ffmpeg and not on debian stable.

Would you please try this once: ffmpeg -y -loglevel repeat+info -i file:67a939c6406c54e348dc9ede72f48303a1fbe255-1610988048301/webcams.webm -i file:67a939c6406c54e348dc9ede72f48303a1fbe255-1610988048301/slideshow.mp4 -map 0:a -map 1:v -c:v copy -shortest 'file:2021-01-18T17-40-48_Séminaire Strasbourgeois.mp4'

Encoding works with this one (with audio output in aac).

$ ffmpeg -y -loglevel repeat+info -i file:67a939c6406c54e348dc9ede72f48303a1fbe255-1610988048301/webcams.webm -i file:67a939c6406c54e348dc9ede72f48303a1fbe255-1610988048301/slideshow.mp4 -map 0:a -map 1:v -c:v copy -shortest 'file:2021-01-18T17-40-48_Séminaire Strasbourgeois.mp4'

I would say I remove -c:a copy from the command and release a new version.

If you want to remove it yourself, it is located here: https://github.com/C0D3D3V/bbb-dl/blob/99447c89178f4cbd4d3d34e07f6a558cf561e2b1/bbb_dl/ffmpeg.py#L99

pprw commented 3 years ago

ok thank. So you prefer to rencode (with a little of audio quality lost - I also read opus was very good with speech, aac less) than risking hazardous behavior with the experimental support of opus inside mp4 of old ffmpeg.

C0D3D3V commented 3 years ago

I think the audio quality of the BBB meetings is not the best anyway, so converting won't make much difference, but if we want to stay with opus, you would have to test that command ffmpeg -y -loglevel repeat+info -i file:67a939c6406c54e348dc9ede72f48303a1fbe255-1610988048301/webcams.webm -i file:67a939c6406c54e348dc9ede72f48303a1fbe255-1610988048301/slideshow.mp4 -strict -2 -map 0:a -c:a copy -map 1:v -c:v copy -shortest 'file:2021-01-18T17-40-48_Séminaire Strasbourgeois.mp4'

remove the output file 2021-01-18T17-40-48_Séminaire Strasbourgeois.mp4 first

Opus command works well (with a little warning "[mp4 @ 0x55c0a9f1c240] track 0: codec frame size is not set").

If I compare both output size, there is quite a difference.

It also take few extra minutes with aac and reencoding.

C0D3D3V commented 3 years ago

ok, thanks for testing.then i change it later in the day, to -strict -2.

pprw commented 3 years ago

Thanks,

Adding

                '-strict',
                'experimental',

line 86 of the ffmpeg.py did it for me.

P-S: (experimental = -2)

C0D3D3V commented 3 years ago

Hope it works now :D I added it to both mix commands https://github.com/C0D3D3V/bbb-dl/commit/838a8d568712ec60a4a1c965c65653587550924b The options of ffmpeg are not so easy to see through in which place they may be placed...
