 hi all,on arm board i have a hardware h264 decoder .   which has exposed decode , postprocess , display api  but in my hardware decoder plugin  i am only calling decode api  in the videosink plugin i call the postprocess and display api  for av sync  but the thing is during video playback  ,  video is leading (much faster)  audio   and av sync is not there. i am using the timestamp and duration generated by parser .     do i have to adjust this timestamp and duration  of buffer passed to videosink , according to decoder speed.(fps)  any ideas
