hi, surfaceflinger composes frame buffer from all the surfaces published by apps and gui.. but when it comes to video buffers, few platforms chose to compose it at display h/w level for better functionality,
movie player app would've already blanked and set transparency for video frame area, thats why we see blank portions. if u might check u can find /dev/video devices, over which video buffers will be posted to display driver, via overlay from stagefright video player driver.. this part cant be captured from user side readily, but with exposing video buffers,it can be processed too for snapshot., On 11/10/11, Girish <htgir...@gmail.com> wrote: > Hi Matt, > > Thanks for clarification. > > So who does the final rendering after merging ?
