Subject: [PATCH] increase keyframes request at stream begin
Increasing the number of keyframes sent at the begining
of a video stream upto 4 (was 1).
Even if the bytes flow is increased (only temporarily)
sending more keyframes at stream begin let a chance to
have a nice video looking in case of possible network
packet drop. It's often the case at the stream begin
due to high traffic caused by the calling establishment
process.
