Hi Dave, In video driver we are not doing any major processing. It is just any interface driver to the h/w video codec. It manages the interrupts coming from the h/w. For decoding and display 4 interrupts are coming, 2 inputs and 2 outputs. If we are using 25fps stream then 100 interrupts/sec. We have disabled the h/w decoding and enabled only display then the playback is bit improved. We are using tasklet to process the interrupts in video driver. We have observed this is causing the issue. Any pointers?
