We put a directshow wrapper around the live555
library and its been going great however there
seems to be on major anomaly.
If the video we are streaming is less than 16
frames per second, all audio is dropped after ~
5 minutes of streaming. This happens on all
formats
Mpeg4, h264, mpeg2, mpeg1, and h263
Every format from above was tested and every
format the audio dropped after five minutes of
streaming. Tests included streaming to a
computer, streaming to a helix, QuickTime, and
Darwin server..
If I set the framerate in the file and or
capture to 16 or above everything runs fine. We
can stream about 3 or so days without any real
issues, however once I lower that framerate to
15 or anything lower then 16, then the audio
will stream with the video for only ~5 minutes.
Then it no longer streams fineĀ video continues
to be fine..
Any ideas.
Not really. However, what do you mean exactly by
"audio is dropped"? Do you mean that - after 5
minutes - your server stops transmitting audio
RTP packets completely? If so, then you should
check to make sure that (1) your audio source is
not closing down (for some reason), and (2) the
"fDurationInMicroseconds" values (set by the
object that feeds into your "RTPSink" subclass)
remain correct.
