<DIV><FONT face=Calibri>Ok. I tried your test program. I tried with
scale of 1 and 2. If the client sends "Range: npt=30.000-60.000" the
server plays starting at 30 seconds into the clip (clip timing information - not
wall time) and plays for 30 seconds wall time (which for scale 2 will be 60
seconds of clip time). </FONT></DIV>
<DIV><FONT face=Calibri></FONT> </DIV>
<DIV><FONT face=Calibri>Shouldn't the server only stream 30 seconds according to
the PTS/DTS and ignore the wall clock time for range not equal to
1?</FONT></DIV>

<DIV><FONT face=Calibri>Thanks. I don't think I made myself clear
though. When I fast forward with a range it doesn't stop at the
requested end time (but it does stop a little while after it). When I
fast forward with a range it seems to get confused and play to
much. </FONT></DIV></DIV></BLOCKQUOTE>
<DIV><BR></DIV></DIV>I don't follow this (perhaps one of the "with"s should have
been a "without"?). But in any case, the best way to test issues like this
is to use the "openRTSP" RTSP client tool. Note the 'trick play' options:
"-s <initial-seek-time>", "-z <scale>", and "-d <duration>"

<DIV>I presume that your server is using indexed Transport Stream files for
'trick play'. If you can reproduce - using "openRTSP" - a specific problem
with one of your files, then please tell us about it (by putting it on a
publicly accessible web server), and let us know the specific "openRTSP"
commands that cause a problem. Then we can test this for
ourselves.</DIV></DIV><BR><BR>
