I use following wowza configuration:
digital headend -> rtp stream to wowza server -> wowza transcoder/streamer to multiple formats.
digital headend and server is connected via internet, there is no bandwidth problem (1Gig CiR) but jitter is quite big, becouse of distance (3000km).
I had to set <Name>audioIsAligned</Name> to false to have it working (without it I had buffering every second on flash or audio skipping on rtsp).
But still I have A/V sync issues:
flash on PC is OK (StrobeMedia)
http streaming on iPhone/iPad is ok for 10 minutes, next it starts to desync A/V and it is worst with each minute (audio is late to video)
with rtsp it depends on player, but generally is desynced too (audio is late to video).
I tried many configuration changes (buffer size, rtpDePacketizerPacketSorterBufferTime etc, but without any changes).
Do you have any suggestion?
