I come again on this thread to explain my project.<br><br>I was able to compile the last version of VLC 1.0.4 under Fedora Core 9 with x264 and live555 libraries (and others).<br><br>I am now able to stream a movie over internet using RTSP (and read it with a VLC client on my computer) but I don't succeed to stream under 50 kbit/sec.<br>
I have tested many different parameters like reducing fps, audio bitrate, video bitrate, size of the movie without success, I got always this speed.<br><br>The flow I am sending is always stream at a bandwidth higher than 50 kbit/sec.<br>
I would like to reduce it to reach 30 kbit/sec even 20-25.<br><br>As anyone of you any idea to tune my VLC command, or any other tips to achieve this?<br>Maybe I hae to use another codec? container? stream protocol method?<br>
<br>I am using this command:<br><br><b><i># cvlc media/video-1.flv --sout='#transcode{fps=8,vcodec=h264,vb=8,width=20,height=15,acodec=mp4a,ab=2}:rtp{mux=ts,ttl=10,name="Video",description="Video",port=1234,sdp=rtsp://<a href="http://192.168.1.2:3130/str/test.sdp">192.168.1.2:3130/str/test.sdp</a>}'</i></b><br>
<br>If I make a test where I try to stream only audio, I reach the same bandwidth of 50 kbit/sec, that makes me thinking that RTSP protocol may not go under this bandwidth?<br><br>The aim is to read movies from GPRS handset.<br>
<br>Youtube for example use RTSP and 3GP container and I am able to play youtube movies from my mobile using GPRS connection although movies are located far from where I live (south pacific).<br>I can not play my own movies from a local server (on internet) using this config although it works with tests done in LAN (player on the mobile is coreplayer).<br>
<br>So what is the difference between youtube solution and this one?<br><br>Best regards,<br><br>Emmanuel<br><br><div class="gmail_quote">2009/12/28 Emmanuel CHANSON <span dir="ltr"><<a href="mailto:emmanuelchanson@gmail.com">emmanuelchanson@gmail.com</a>></span><br>

<br>
i have been using h263 + amr_nb with 50kbps (176x144 px, 10fps).<br>
if you have a mobile handset that only supports GPRS, then i doubt it supports any newer codecs either.<br>
