[Live-devel] New LIVE555 version, now supports 'trick play' on H.264 Transport Stream files

[Ross Finlayson]

(Note that this particular problem has nothing to do with 'trick 
play'; your streaming problem happens even if no index file is 
created.  It probably also doesn't have anything specifically to do 
with H.264 (see below).)

Problems like this (VLC being able to play a file OK, but 
'stuttering' if the same file is streamed from our RTSP server) are 
usually caused by a problem with the PCR timestamps in the file. 
(The server's "MPEG2TransportStreamFramer" object - which regulates 
the rate at which the data is output - uses the file's PCR timestamps 
to dynamically compute an estimate of the 'duration' of each 
Transport Stream packet, which in turn is used by the server to 
dynamically compute the rate at which data should be sent.)

I suspect that perhaps your file is highly 'VBR' (variable bit rate), 
and the PCR timestamps are not occurring in the file frequently 
enough for our "MPEG2TransportStreamFramer" to properly adapt to it.
