<div style="RIGHT: auto"><SPAN style="RIGHT: auto"><SPAN style="RIGHT: auto" class=tab> Thanks for your reply.</SPAN></SPAN></div>
<div style="RIGHT: auto"><SPAN style="RIGHT: auto"><SPAN style="RIGHT: auto" class=tab>1. How and where can I change the bitrate of the HTTP stream so that the delay time can be reduced? </SPAN></SPAN></div>
<div style="RIGHT: auto"><SPAN style="RIGHT: auto"><SPAN style="RIGHT: auto" class=tab>2. Regarding my second query below, after RTSP over HTTP tunneling the extension of the file name was missing (Original file petrov.m4e and after tunnelling it was video-MP4V-ES-1). Next I had to rename the file as video-MP4V-ES-1.m4e and then it was possible to display the same.</SPAN></SPAN></div>
<div style="RIGHT: auto"><SPAN style="RIGHT: auto"><SPAN style="RIGHT: auto" class=tab>3. This is regarding the "trick play functionality". Under the link: <A href="http://www.live555.com/mediaServer/#trick-play">http://www.live555.com/mediaServer/#trick-play</A>, it says that the feature is not supported by all the media types. Can you please let me know the suported media types? (Do not know if the media types in the link given is recent & up-do date)</SPAN></SPAN></div>
<div style="RIGHT: auto"><SPAN style="RIGHT: auto"><SPAN style="RIGHT: auto" class=tab>4. This is regarding the MPEG2Transportstreamindexer. In the link <A href="http://www.live555.com/liveMedia/transport-stream-trick-play.html">http://www.live555.com/liveMedia/transport-stream-trick-play.html</A>, there is a comment which says:</SPAN></SPAN></div>
<div style="RIGHT: auto"><SPAN style="RIGHT: auto"><SPAN style="RIGHT: auto" class=tab>"<EM style="RIGHT: auto">(Be warned that this program is currently rather slow, so I suggest running it on the fastest computer that you have.)</EM>" My concern is this will have a great impact on the performance if I am executing this in a embedded system ?</SPAN></SPAN><BR></div>

<DIV><SPAN>1. I am using Ubuntu 10.04 LTS and used two instances of the terminal ; one running live555mediaserver and the other retrieveing bipbop-gear1-all.ts using "./openRTSP -T 8000 <A rel=nofollow>rtsp://10.0.2.15:8554/bipbop-gear1-all.ts</A>". This file which is given as a test file is around 44.5MB. It took 1807 seconds (~30 minutes). Is this delay of transmission normal or I am facing some other problems?</SPAN></DIV></DIV></DIV></BLOCKQUOTE>

<DIV>No, it just means that the bitrate of your HTTP stream was 197 kbps.</DIV>

<DIV><SPAN>2. Next I followed the same procedure for a m4e file (petrov.m4e; an example file in m4e format). Even though I was able to successfully retrieve it. the type it generated was "unknown". Hence I could not play the stream (unlike the bipbop-gear1-all.ts which was retrieved as MPEG2 transport stream and was successfully able to play with movie player).</SPAN></DIV></DIV></DIV></BLOCKQUOTE>
<DIV><BR></DIV>This just means that the media player application that you used does not understand how to play MPEG-4 Elementary Stream Video files.</DIV><BR><BR>
