Transport Strea</title></head><body>
<blockquote type="cite" cite><font face="Arial" size="-1">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.</font></blockquote>

<div>That's odd. Are you using the latest version of the code?
(Version 2007.07.01 fixed a bug that affected 2x speedup (although it
should not have affected 4x speedup).)</div>
<div><br></div>
<div>I have tested the latest version of the code (2007.07.10), and it
works OK for me.</div>
<div><br></div>
<div>(In each case, I modified the call to "playMediaSession()"
at line 65 of "testProgs/openRTSP.cpp".</div>

<blockquote type="cite" cite><font face="Arial" size="-1"> 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)?</font></blockquote>

<div>Not for Transport Streams, with our implementation.</div>
