ADV212 decoder buffering

I have read several thread about buffering but still have questions about it.


On our system we see an increase in latency after some time.


I assume it's caused by the fact the decode clock is not synced with the encoder one.


But it seems that the decoder buffers several frames (about 7) before it holds of the sender (by not giving the fifo empty signal).


This means that we get an increase in latency of several 100's ms before we detect we send data too fast.


questions :


1) Am i right that the ADV can buffer several frames ?

2) How can we force the ADV to buffer only one frame ?
