Ability to play DASH m4a audio (youtube-dl)

[cheesegrate]

Love the program. It would be great to be able to play audio mp4a files , sourced  from youtube.  At the moment I have to convert the file using ffmpeg or online, but windows media player can play the youtube mp4a file.

An explanation why it cannot be currrently played is found here.

"The problem is that for YouTube DASH, the MP4 container's ftyp has the "major brand" set to dash instead of m4a. This is the correct approach for DASH streaming, but Winamp is too old to recognize it (and many other programs are)."

if you rename the file with a .m4a extension, can MB play the file?

It actually is an m4a file and is downloaded as such. But does not play in Musicbee but plays in windows media player.
.A good description is found here  http://kwizzu.com/construct.html
"A while back YouTube started to use DASH format (Dynamic Adaptive Streaming over HTTP) for 1080p and 480p videos. DASH is an adaptive bitrate streaming technology where a multimedia file is partitioned into one or more segments and delivered to a client using HTTP. Now instead of single multimedia file, there are at least 2 separate files: one with the audio line, the other — video. "
"The audio file has the mime-type: "audio/mp4" and therefore should have the file extension: "m4a" or "mp4" "

it might be worth trying bass_aac.dll
extract it from this zip: http://uk.un4seen.com/files/z/2/bass_aac24.zip
and place in the musicbee application folder and restart
I dont have time to check this myself

What are you using to download the audio from YouTube?
It sounds like that program should do a better job of creating a "proper" aac file.

As stated its a problem with the bass.aac dll and thus not a musicbee problem.

I found a plugin that fixes the m4a file using ffmpeg automatically. https://addons.mozilla.org/en-US/firefox/addon/complete-youtube-saver/

Thanks all.

i dont see where you say you are using bass_aac.dll but if you are already, then i really doubt the bass developer would be willing to spend time enhancing it.
If you are using windows 7 or above then there is also an aac decoder with windows. If you already tried before installing bass_aac.dll then i dont have any other suggestions
