youtube-dl gives invalid argument error

[illumilore]

It seems to be caused by how it calls ffmpeg?

Can you run the following command and paste the output?

ffmpeg -y -i 'Forget _ Pogo-vOreqez4v9Y.f137.mp4' -i 'Forget _ Pogo-vOreqez4v9Y.f141.m4a' -c copy -map 0:v:0 -map 1:a:0 'Forget _ Pogo-vOreqez4v9Y.temp.mp4'

[yan12125]

Due to the --disable-muxers and --enable-muxer='flac,gif,image2,image2pipe,matroska,matroska_audio,null,webm' in configuration flags, mp4 as the output format is not supported. There are several options:

1. As a temporary workaround, add --merge-output-format mkv to youtube-dl to force matroska format
2. Change the compilation flags. If you are using the official version of ffmpeg, try to contact the package maintainer of SuSE.

[jaimeMF]

I'm closing the issue, follow one of the options posted by @yan12125.

[illumilore]

Since it is apparently an official ffmpeg build, would it be a good idea to have youtube-dl detect when ffmpeg has this problem and give better feedback than "ERROR: xxx.mp4: Invalid argument"?
