FFMPEG Encode .avi/.mov with alpha channel to .3g2 (with alpha kept)
<p>I'd like to convert my 32bits videos (either .avi or .mov) RGB+A, to .3g2 format with FFMPEG, and keep the alpha channel.</p>

<p>It should be something like that</p>

<pre><code>ffmpeg -i C:\Users\naldo\Desktop\test.avi  -vcodec libx264 -acodec libfaac -ab 48k -ar 22050 -ac 2 C:\Users\naldo\Desktop\test.alpha.3g2
</code></pre>

<p>but it's not working.
Any ideas ?
Thank you !</p>
