[vlc] Re: http at high rates

[Marcelo Manzato]

Hi Viktor,

One computer (windows, P4 Intel 2GHz, 768 MB RAM) is
capturing the video content (no audio), encoding under
mp4v/ffmpeg and transmitting to darwin streaming
server. The command I use for that is the following:

vlc.exe -vvv dshow:// :dshow-size="640x480" --noaudio
:sout=#transcode{vcodec=mp4v,vb=2000,fps=30,venc=ffmpeg}:rtp{dst=192.168.0.1,port-video=20000,ttl=8,sdp=file://C:\main.sdp}

Then, another computer (linux, P4 Intel 3Ghz, 1GHz
RAM) requests that content from Darwin, and makes
available the html access, from the following command
line:

vlc -vvv rtsp://192.168.0.1/main.sdp --noaudio
:sout="#duplicate{dst=std{access=http,mux=ts,url=:8080}}"

Under these conditions (2 Mbps of bitrate) everything
seems to be fine, however, I want higher bitrates
(about 15 Mbps), what causes the problems previously
rited if I increase the vb parameter from the encoder.


Thanks for your atention.
