It's not playing mms:// streams about aacplayer-android

[GoogleCodeExporter]

Hi !

As far as I know the mms:// protocol was deprecated by Microsoft and currently 
mms:// means rtsp:// (which should be supported by Android)

Anyway if you really want to play mms (whatever it is called for) using FFmpeg, 
then it would be probably feasible by doing the following changes:
   * the strem sync function need to be configurable according to the stream type / decoder (currently there is always called aacd_probe() which looks for ADTS sync word)
   * the MMS related source files of FFmpeg need to be included in the project build (currently I extracted only AAC related sources).

But I am not planning to do it, unless I get realized that this would be 
helpful for a lot of users.

Thank you for response.

As to mms:// protocol: Microsoft might have deprecated it but one in three 
radio stations still use it and publish links to radio streams as mms://....

If you were to include this change in your code it would make your player work 
with 30% more radio streams on the net. That's huge!

Let me know what you think.

Just looked more at mms:// and WMA and realized that it would be more painful 
to adapt the current project to it (need also to rewrite the data fetching - 
mms:// uses more complicated communication). Also FFmpeg library uses floating 
point arithmentics, so it will be working fine on modern devices only (that's 
why OpenCORE aacdec with fixed-point arithmetics was the "winner" for AAC).

Sorry, I will not spend more time on it in near future.

Please try to look at RockBox project http://www.rockbox.org/ .

Never say never again :-)

Ok revision 23 
 - support of mms:// added (MMSInputStream --> libmms) - standalone part
 - support of ASF/WMA demuxer/codec added - using FFmpeg

Status:
 - it is working for some streams, but not tested thoroughly
 - possible memory leaks - code not reviewed yet
 - code not optimized 

OK:
  mms://live.cumulusstreaming.com/KTOP-AM
  mms://wmc1.den.liquidcompass.net/WTAWAM

Not-really-OK:
  mms://media.blackcrow.fm/wndb

KO:
  mms://70.61.202.210:3006/   (problem in libmms)

Rev#24 - fixed problem with variable frame size.
OK mms://media.blackcrow.fm/wndb

There was an idea to link libmms and ffmpeg together. But using of 
BufferArrayReader might help with buffering the stream. 154% performance on 
emulator is enough - it should be working fine on all Android devices.
