Function pointers are used for templated functions instead of needlessly
duplicating many functions.

This will allow the same struct to be used for both the fixed and float ac3
encoders.

functions.

Needs some ARM/PPC asm modifications.

It was broken in 4:4:4, and still did chroma deblocking for no reason in 4:2:0.

Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.

Currently, the parser is buggy and only processes the stream extradata
when the flag is set. This fixes it to actually inspect the frames.

Whitespce will be fixed in a separate change.

Use push/pop instead of stmdb/ldmia for stack operations.  This
is the preferred syntax.

This reverts commit a50f0bea.

This has been implemented differently in qatar and its better they
maintain it for me instead of me having to spend an average 5sec more

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.

By observation it did not seem to handle prev_frame_num > frame_num.
This does not affect any files I have.
