RTSP bug 831645 / Bechen

• RTSP bug 831645
  • waiting for review
• bug 877116 - [RTSP] audio playback latency is serious with the following media streams(Video:H.264 Audio:AAC)
  • According to rfc3640, we can divide a RTP packet into several Access-Unit, and calculate the timestamp for each AU.
    • It works now, but since we divide a RTP packet into several small pieces, also increase the ipc loading. And we observe the smallest aac AU is only 9 bytes (silence aac frame), means that a RTP packet will be divided into more than 100 AUs corresponding to 100 ipc, 100 slots. Then we must adjust the slot buffer number in RTSPTrackBuffer bug 877193.

• The b2g process crash on our ipc call "onMediaDataAvailable", seems we can't do ipc on android thread. Help by / Cervantes.
