Dear all, I’m using FFMPEG.exe on Windows. Using an exec command in a PHP script I’m converting wmv, mov and mp4 to swf or flv. Everything goes great but when converting wmv or mov to either swf or flv the audio goes first than the video, so no synchronization in between voices and people when they speak. The video starts playing a few seconds later than the audio. How can I solve that?? Warning: I’ve only been using FFMPEG for a week This is the command that I’m giving to FFMPEG trough the PHP script: ffmpeg -i movie.mov -ab 64 -ar 44100 -b 200 -r 15 -s 256x188 -y movie.flv Thanks a lot in advance!!
