<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Hi all,<br>
<br>
I would like to clarify one thing about tv streaming. <br>
I'm using this command line : <br>
<br>
vlc -vvv --color --sout
'#transcode{vcodec=mp4v,vb=4000,venc=ffmpeg{keyint=80,hurry-up,vt=800000},scale=1,acodec=mpga,ab=128,samplerate=44100}:std{access=udp,mux=ts,pcr=100,url=<a
href="http://239.255.1.1">239.255.1.1</a>,sap,name="F2"}'
v4l:/dev/video0:size=640x380:frequency=623250:norm=secam:adev=/dev/dsp:audio=0<br>
<br>
One thing I'm not clear with is the codec stuff. I thought that in a video
codec, there was sound layers no ? (ex: mpeg). So why do I have to put a video
and an audio codec there ?<br>
<br>
I know this is a basic question, but if someone could explain it to me it would
help a lot !!<br>
<br>
Thanks<o:p></o:p></span></font></p>
