    Audio/Video out of sync on recorded stream

    joyrex

      Hi,

      i'm recording a stream server side using the stream object with pretty much the following code:

       

      mystream = Stream.get("mp4:recording.mp4");

      mystream.setBufferTime(5);

      mystream.record();

      mystream.play("live", -1, -1);

       

      and stopping with:

       

      mystream.record(false);

      mystream.play(false);

       

       

       

      After that i process the file with the f4v post-processing tool using the command:

       

      f4vpp -i recording.mp4 -o output.mp4 -c

       

      but no matter what i always get desynced audio and video and sometimes even the frame size is completely wrong, for example i get a 640x360 stream at 320x240 with both aspect ratio and size wrong.

       

      What am i doing wrong? Is there a procedure that needs to be followed or a particular configuration to have usable recordings server side?

       

      Thanks
