Hi,
Is it possible to detect scan type (progressive or interlaced) of a video
file in stagefright?
I see below listed fields are query-able with metadata of file through
stagefright, but not scan-type which i guess is avaiable in MP4 file header.
Any hint on how to detect scan-type of video file at Stagefright player
driver? Or is it available in opencore??
Thanks,
Deva
