<DIV><FONT face=Arial size=2>Hi Ross,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have noticed that when I'm recording video stream
to AVI file using LIVE555 (evein if I'm using openRTSP sample app),
the output file does not contain any key frames exept for the very first
one.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>E.g. when I open the recorded file in Virtual Dub
and go to FIle->File Information, the "Number of key frames" is always 1,
whatever is the length of the recorded video. </FONT><FONT face=Arial size=2>Or,
if </FONT><FONT face=Arial size=2>I execute search for the key frame using
</FONT><FONT face=Arial size=2>AVIStreamFindSample() VFW API function, it always
return 0 (the very first frame), whatever start search position I do specify in
call.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>
<DIV><FONT face=Arial size=2>As a video source I'm using Axis 241S/241Q video
servers, and they are configured to stream I-frame followed by 7
P-frames </FONT><FONT face=Arial size=2>(GOV Settings Structure: IP,
Length: 8).</FONT></DIV>
<DIV> </DIV>
<DIV>Could you please advise what could be the reason of such strange
behaviour?</DIV></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Kind regards,</FONT></DIV>
