I come again on this thread to explain my project.
I was able to compile the last version of VLC 1.0.4 under Fedora Core 9 wit=
h
x264 and live555 libraries (and others).
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.
I have tested many different parameters like reducing fps, audio bitrate,
video bitrate, size of the movie without success, I got always this speed.
The flow I am sending is always stream at a bandwidth higher than 50
kbit/sec.
I would like to reduce it to reach 30 kbit/sec even 20-25.
As anyone of you any idea to tune my VLC command, or any other tips to
achieve this?
Maybe I hae to use another codec? container? stream protocol method?
I am using this command:
*# cvlc media/video-1.flv
--sout=3D'#transcode{fps=3D8,vcodec=3Dh264,vb=3D8,width=3D20,height=3D15,ac=
odec=3Dmp4a,ab=3D2}:rtp{mux=3Dts,ttl=3D10,name=3D"Video",description=3D"Vid=
eo",port=3D1234,sdp=3Drtsp://
192.168.1.2:3130/str/test.sdp}'*
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?
The aim is to read movies from GPRS handset.
Youtube for example use RTSP and 3GP container and I am able to play youtub=
e
movies from my mobile using GPRS connection although movies are located far
from where I live (south pacific).
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).
So what is the difference between youtube solution and this one?
Best regards,
Emmanuel
