[android-developers] Re: Stagefright Mediaextractor: how to detect interlaced streams in video files?

2010-10-21 Thread Shashank 
Yes Deva, You are right.

The information regarding interlace is stored in compressed bit
stream.

Codec component should be able to provide this information to the
application, i.e. OMX Client. In case of Android :: Stagefright, its
OMXCodec.cpp.

Once this information is retrieved, developer can choose to do field
interlacing / selection for display at awesome player.
