Hello, I have grabbed and encoded a streaming video with the following command mencoder $1 -o $2.avi -oac mp3lame -lameopts vbr=2:aq=3:q=3:abr:br=192 -ovc lavc -ffourcc DX50 -lavcopts mbd=0:vbitrate=1800:aspect=16/9 -vf harddup=1 -channels 2 -srate 32000 -ofps 29.97 -vf scale=720:404 I got a file with 0,5 seconds desync so I reencoded it with mencoder $2.avi -o $3.avi -ovc copy -oac copy -delay 0.5 Then I got a perfectly good file when playing with mplayer though all other players (vlc, windows media and my pioneer dvd player) refused to recognize the delay header. I`ve read in the internet that -mc 0 option could be helpful when encoding in the first place. But I do not want to redownload the movie. 1/ Is there any way to cut 0.5 seconds from the start of the audio track? 2/ What options should I`ve used in the first place to avoid such a problem? Thank you for your answers. I appreciate your time. SDA
