weird video behaviour in Stagefright

In stagefright, if any weird behaviour is observed in video. Following
steps need to be taken:

1.we need to print time taken by parser and decoder.[To check any time
taken process involved]
2.Check any frame is dropped by enabling log [dropping late frame in
awesomeplayer.cpp]
3.Print logs in all sleep() fn in AwesomePlayer[while rendering
frames, threads might go to background and wont do anything because of
Sleep() fn
4.Check for any postVideoEvent(10000ms) this might delay the rendering
of frames. For optimization or any other reason, chipset vendors might
tune this
