Ross,
I am able to test trick mode functionality using
testMPEG2TransportStreamTrickPlay at various scales and in both
directions. However, when I try to test with openRTSP I see some
strange results. I modified the call to the function playMediaSession()
as you describe in a previous thread ("Trick play problems", 4/16/2007)
to accept arguments for start time, end time, and scale. I am using a
start time of 0.0f and an end time of -1.0f. With a scale of 1.0f,
everything works well, with openRTSP creating a file (video-MP2T-1)
locally. When I try scale = 2.0f, it still creates the same file, but
with the same size and scale as the first (verified by playback with
VLC). If I try scale = 4.0f, openRTSP creates the file video-MP2T-1,
but it remains at size zero and openRTSP appears to do nothing. I need
a method of verifying trick mode over RTSP. Also, the directions for
using Trick Mode state that the scale must be an integer. This means
that scales less than 1 are not support (i.e. slow motion)?
Thanks,
