Ok this makes things clearer.<br>
so here, with this : '#transcode{vcodec=mp4v,vb
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">=4000,venc=ffmpeg{keyint=80,hurry-up,vt=800000},scale=1,acodec=mpga,ab=128,samplerate=44100}

<div><br>
I am choosing bith a video and an audio codec, no ? <br>
I don't see the point of choosing the audio codec if there are already sounds layer in a video codec.<br>
<br>
thanks a lot for your help,<br>
<br>
</div>ps : does anyone know where I can find a list that would give all
the key words corresponding to the codecs (ex : mp4v -->
mpeg4, mpga--> mp3...etc ) thanks <br>
