[Live-devel] RTSP latency on Android Clients

Hi,

On Android clients RTSP playback has a latency of around 5-6 seconds. The
client buffers data for this duration and then starts playing.
For live streaming this latency is very high.

Does the client use the bandwidth information (b=AS:<bandwidth>)  to
calculate the buffer size. e.g 5-6sec in this case?
How is the bandwidth computed in the Live555 ?

Did some search and few people suggested to do a buffer blasting initially
when the session starts. i.e send data at a high rate at start so that the
client buffer fills up fast and eventually reduce the startup latency.
Can streaming framerate be controlled at runtime in Live555 ?

Regards,
Sambhav
