• youtube-dl got a 3gp file, apparently it doesn't contain any video streams

  27 juillet 2018, par Albertinio

  I tried downloading a video with youtube-dl with 3gp format. When I try to play it on VLC or any other application it doesn’t play. This is the output I get when trying to download it again.

  With this information, I don’t know how to proceed. I already tried ffmpeg with the max analyzeduration and probesize and it still doesn’t work. Any ideas ?
