Raw audio stream muxer

[linuxstb]

This still needs a bit of cleanup, but it's working for me to stream or record the first audio stream in a service (i.e. a Radio station, but can also be used for recording/streaming audio from a TV channel) as a raw MPEG/AC3/AAC audio stream (i.e. no container at all).

NOTE: Please ignore the 6944425 commit, not sure how that got in here...

@linuxstb check with @andoma and @john-tornblom, but I don't see any reason to include once its cleaned up.

I was always speculating about something like this.
My use case is that I might be able to save bandwidth while streaming. I am blind and if I am wathing or maybe better to say listening TV alone I dont need video displayed at all. Being able to only stream audio would be fantastic for example in conjunction with tvhguide for android.

I am happyly using this. I have also tweaked tvhguide for android to include this muxer in its options and I can stream the audio over mobile internet.
What I would like to do is to encode the audio to vorbis or into he aac. I think both should be doable with ffmpeg or libav.
I know once the transcoding support gets merged it should become perfectly doable.
Is there a patch or something that I might be able to experiment with and possibly to get this functionality now or is it more complicated with transcoding?

@linuxstb you still want this included? Does it need tidying up?

Remove the has_video variable - it is not used...

@linuxstb can i please rebase ... ?
@perexg any hope to add this to master ??

[piotrasd]

i record many tvshows or movies just for audio (but alwayes i must manual extract from full record) so this is perfect solution, i hope @perexg you find time to add this
