After applying the recent security patch and updating MPlayer, the videos may not be converting to flv. The videos may not be playing as well if your YouTube clone script uses mencoder to convert them to flv. We noticed that one vendor’s script uses this phrase
which needed to be changed to this
Those who are using ffmpeg for conversion need not worry.
Side Note: We noticed that ffmpeg converted a 90MB wmv file into 240MB file. But using mencoder we got 95MB flv file. mencoder seems to be a winner here.
