Stefano Sabatini 712d82130e lavfi/avfiltergraph: apply misc fixes to fix avfilter_graph_request_oldest() @return doxy 2012-07-18 17:13:00 +02:00
Nicolas George d483867525 avfiltergraph: document a catch in request_oldest().
This one is tricky. Consider a graph with two sink links, A and B.
request_oldest() requests on A, and A returns EOF. This EOF causes
a filter to flush pending frames to B; they are unrequested.
Then request_oldest() moves on to B, and B returns EOF.

used in application code, so it is better to consider them internal
functions, this can be changed later if necessary. Simplify API.
