/*commenting below code as with 1080P Decode we see a sync lost digit for
first frame as it takes long time to decode but it later recovers*/
is commented out is that , The sync lost digit can be got for several reasons . One of the reasons is that when IVA-HD decoded video is played on HDMI , then the first frame takes about 1s to decode and results in a SYNC_LOST_DIGIT, which if the code is not commented would disable the overlay manager.

Now coming to the SYNC_LOST_DIGIT as such , It would be helpful if you could elaborate on how you are able to reproduce the issue.I assume the timing set is correct.
