Feature request: DASH support

[jyio]

I use youtube-dl to grab URL's of audio streams from YouTube videos, which I then feed directly into jPlayer. Quite often, only m4a is available, but this isn't the usual m4a format -- it's DASH. Chrome/Chromium browser supports the format natively, so jPlayer uses html mode. Firefox doesn't, so jPlayer uses Flash, which also doesn't know what to do with DASH.

How does one obtain a DASH file? Like this:

$ youtube-dl -F https://www.youtube.com/watch?v=0P23b8rEe7I
...
141          m4a        audio only DASH audio  256k , m4a_dash container, aac  @256k (44100Hz), 10.45MiB
...

$ youtube-dl -gf 141 https://www.youtube.com/watch?v=0P23b8rEe7I

$ wget `youtube-dl -gf 141 https://www.youtube.com/watch?v=0P23b8rEe7I`

Note that if one used youtube-dl to download the file directly, i.e.

$ youtube-dl -f 141 https://www.youtube.com/watch?v=0P23b8rEe7I

[ffmpeg] Correcting container...

it would use ffmpeg to copy the data into a normal m4a file. Unfortunately, this needs to be done on the server.

It would be awesome if jPlayer could play DASH files/streams directly :)
Thank you for entertaining my request.
