Downloading fails (no video nor audio, just subtitles partially)

[jluttine]

Only subtitles downloaded (and partially/corrupted), no video nor audio:

Any ideas what's wrong?

Which version of ffmpeg do you have? ffmpeg -version

If you analyze the downloaded file with ffprobe, does it detect video or audio streams? ffprobe "John Wick-2020-11-01T21:00.mkv"

I'm able to download it with video, audio and subtitles. I have ffmpeg 4.3.1-5.

You can also try the wget backend as a backup download method. It select an alternative stream, which might work even if the default one fails.

yle-dl --backend wget https://areena.yle.fi/1-50173661

wget backend seems to work.

Hmm, your ffmpeg seems fine as far as I can see. The only explanation I can think of right now is that you would be missing some video encoding library, but ffmpeg should report an error in that case.

Does it reveal anything more if you try the verbose mode: yle-dl --verbose https://areena.yle.fi/1-50173661 ? You can even try the --debug switch.

I'm closing this old bug report because I'm not able to reproduce it and I think that the Areena stream format has changed anyway.

Please feel free to open a new report if you still encounter broken streams!
