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. regards Shashank On Oct 4, 1:50 pm, Deva R <r.deva...@gmail.com> wrote: > [resolved now] > > i realized lately that its beyond the scope of file parser., and > supposed to be done by codec component. > written a custom parser to detect interlaced content, > and posted to local gerrit -http://review.omapzoom.org/#change,6889 > > -- > Regards, > Devawww.bittoggler.com > > On Tue, Sep 7, 2010 at 4:14 PM, Deva R <r.deva...@gmail.com> wrote: > > Hi, > > Is it possible to detect scan type (progressive or interlaced) of a video > > file instagefright? > > > 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 atStagefrightplayer > > driver?
