[gst-devel] why audio is used as a reference in AV sync.

[amitpandya at itimes.com]

Hi all,

I have a question regarding AV synchronization.

Normally when we deal with both audio+video data processing in gstreamer,
we takes audio as a reference for AV synchronization and not the video frames.

Why is it so?
What is the advantage of doing so?
Why shouldn't we tak video frames as our reference while synchronization at muxer?  

Thanks,
Amit Pandya.
