This also makes youtube-dl use the better "Source" format by default.
Unfortunately, we lose a part of the description in the new JSON format, but that's still better than a non-functioning URL.
Multiple formats can be requested using `-f 137+139`, each one is downloaded and then the two are merged with ffmpeg.
something.temp.{ext}
ffmpeg correctly recognize the formats of extensions like m4a, but it doesn’t works if it’s passed with the `—format` option.

We could also set up a formula which would weigh filesize/bitrate and vcodec/acodec (say, 1GB h264 < 3 GB MPEG2 < 2 GB h264), but that would get really messy real soon.
It has a better bitrate than 137 but the same resolution
