It makes the intent clearer and avoids calculating the length
separately.

While no decoder currently exports spherical information, this type
represents a frame property that has to be passed through from container
to frames.

Add some bounds checking to CLLC; reduce HQX variable scoping,

This filter is not required anymore with aformat. Drop it at next bump.

We do not support using filters without AVFilterGraph in practice
anyway, so there is no point in pretending we do.

This is more consistent with the naming in the rest of Libav.

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.

Keep a heap of all sink links ordered by timestamps.

This is required for letting applications to create and destroy
AVFilterInOut structs in a convenient way.

Unlike avfilter_graph_parse(), it returns unlinked inputs and outputs
to the caller, which allows parsing of graphs where inputs/outputs are
not known in advance.

It will be used for logging, possibly also AVOptions.

Make it clear that open_inputs/open_outputs are updated only if non-NULL.

This is required for letting applications to create and destroy
AVFilterInOut structs in a convenient way.

Make it returns the list of open inputs and outputs, so it can be
reused by applications.

Breaks API/ABI.
