Hello, i am working on interactive streaming and i am using the live 555
media library to deliver my packages encoded in x264 to a vlc client.
In order to improve the performance of the interactive streaming i have to
develop an adaptative algorithm based on the vlc player buffer size and i
should be able to modify this buffer(make it shorter) size to achieve a
faster response of the switching of the streams in the client size.
Do you know if it is possible to define dynamically or statically from the
server side, the size of the buffer of the client of the streaming?
Is there any option through the rtp, rtcp or rtsp protocol?
Yes, you can use the RTCP-provided "jitter" statistic for this
purpose. Note the "RTPReceptionStats" class. To access this class,
see, for example, how "openRTSP" implements the "-Q" option.
To be honest, I'm not sure how you would use the "jitter" statistic
to calculate an estimate of the client's buffer size, but there's
probably information out there on the Internet about this...
