Hi All,

I am trying to play MP4 file with AC-4 audio track in it. Looks like like
Qedemux is not able to undetstand the AC4 audio format.
Looked at the qtdemux file, there is no handling of AC-4 format in
it.Digital Silence is observed while playing this file.
So to support this format and play this mp4 file, what is the right
approach: extending the qtdemux or writing the ac4 parser & connect it to
qtdemux in the pipeline? can someone please clarify.
 
Also is there any spec/documentation available for this?
Thanks for help.

Thanks
