[Live-devel] Adding secondary audio track to existing H264 RTP stream

[Marcin]

Didnt want to cross post but this is a debug info from afterGettingFrame 
- microseconds delay between each calls of this function:
fDurationInMicroseconds 23219
Time diff 25142
fDurationInMicroseconds 23219
Time diff 44613
fDurationInMicroseconds 23219
Time diff 25751
fDurationInMicroseconds 23219
Time diff 24478
fDurationInMicroseconds 23219
Time diff 26883
fDurationInMicroseconds 23219
Time diff 38700
fDurationInMicroseconds 23219
Time diff 39877
fDurationInMicroseconds 23219
Time diff 44183
fDurationInMicroseconds 23219
Time diff 25986
fDurationInMicroseconds 23219
Time diff 40029
fDurationInMicroseconds 23219
Time diff 25459
fDurationInMicroseconds 23219
Time diff 24081
fDurationInMicroseconds 23219
Time diff 40059
fDurationInMicroseconds 23219
Time diff 44288

Why i have so huge gaps?

Because of this, you *do*, indeed, need to call "scheduleDelayedTask()” yourself - because our Transport Stream multiplexing code (“MPEG2TransportStreamFromESSource.cpp”) currently doesn’t do anything with the “durationInMicroseconds” parameter that it gets passed from the upstream source.  (That multiplexing code was written with the assumption that all input sources (for the Transport Stream) will be ‘live’ input sources (rather than pre-recorded data).  That’s not the case for your application.)
