Here's the code. good luck getting mencoder working properly, I had to
ask a friend to help recompile it. Also, mencoder won't add the
metadata like length to the file so you have to do that with flvtool.
That way the player can show a progress bar.
// convert the video to FLV
$encoder = "mencoder " . $file["tmp_name"] . "
-o
../webroot/img/media/videos/" . $this->Video->id . ".flv -of lavf -oac
mp3lame -lavcopts
vcodec=flv:vbitrate=300:cbp:mv0:mbd=2:trell:v4mv:predia=2:dia=2:last_pred=3
-vf scale=320:240,harddup -lameopts br=64 -ovc lavc -ofps 25 -srate
22050 -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames >
/tmp/encoder_log";
// add flv metadata
$encoder .= "; /usr/bin/flvtool2 -U ../webroot/img/media/videos/" .
$this->Video->id . ".flv";
$encoder .= " 2>&1 &";
exec($encoder);
// make video thumbnail
$thumbnail = "mplayer -nosound -vo
jpeg:quality=100:outdir=/tmp -ss
1 -vf scale=320:240 -frames 3 " . $file["tmp_name"];
exec($thumbnail);
