audio sync problem

[rakan]

I have a audio sync problem...

When I mux my mp4 video with my compressed ogg audio file everything is fine at the beginning of the video. However, by the end of the video the audio starts to play too early.

My compressed MP4 video is 1:41:06:643 in length
My compressed OGG audio is 1:41:05:824 in length
The difference is 819 ms.

Do I need to fix my audio file so it's the same length as my video file? What software do I used to do this?

nvm

Just figured out how to stretch the audio using mkvmerge..

i doubt there is the need the stretch the audio. in fact i assume you used a wrong video framerate. the default one in mp4box is 25fps, it might not be the correct one for your video stream
