Streaming over low bandwidth using speex and IceCast server

[hammadkom]

The problem
"given the server ip is 192.168.1.6 "

if you are streaming file

Code: Select all

vlc.exe -vv C:\test.mp3 :sout=#transcode{acodec=vorb,ab=96,channels=2}:duplicate{dst=std{access=shout,mux=ogg,dst=source:hackme@192.168.1.6:8000/audio.ogg}}

if u r streaming from audio card this will work
(with speex codec http//www.speex.org)

Code: Select all

vlc.exe -vv dshow://dshow-adev="" :sout="#transcode{acodec=spx,ab=8,channels=2 }:duplicate{dst=std{access=shout,mux=ogg,dst=source:hackme@192.168.1.6:8000/audio.ogg}}"

both are working fine with audio
but now i have a problem , which is what is the best config for speex codec to reach 4 kbps with vbr or cbr

also when i see the streaming rate i see very high traffic rate !!!! amazing

see my reply to get the answer of this problem

Answer:

Peace upon you

after many many trials and effort i reach to this result

Code: Select all

vlc -vvv --color dshow://dshow-adev="" --no-video --sout "#transcode{acodec=spx,samplerate=2000,channels=1,aenc=speex}:std{access=shout{name="mystream"},mux=ogg,dst=source:hackme@192.168.1.9:8000/audio.ogg}"

the previous code reduce the bit rate to 7 kbps

you can increase the bit rate and quality , by increasing the sample rate to 3000 or 4000 or higher according to your needs , for example if you change "samplerate=2000" to "samplerate=4000" the resulted output bit rate will be 14 kbps

i hope this result help people for progressing thier work


if any one benifit from this result please say thanks and pray for me
