All We've inserted a custom filter into our transport stream recording chain. Almost all the time it works (and has been working pretty well for many months), but lately we've seen this problem:
data is being streamed towards our unit, and RTP packets are being buffered; when our problem occurs, one of the 'downstream' filters seems to stop requesting new data RTP packets 'pile up' in memory and no data is written to our recording file. We wanted to check our understanding of the normal source-to-sink chain processing. The network side of our chain depends on being called from its sink-ward filter to get started, but afterwards continues on its own to get RTP packets from the network. When called on it will provide data to its sink, but the part that pulls in RTP packets from the network won't hang or stall if it's getNextFrame() is never called by its sink.
