As a sideeffect this makes the code more robust if a future change leaves
a path where it may be uninitialized otherwise.

The GRAPH_DESCRIPTION string supplied to graph2dot must include explicitly
defined inputs and outputs which are not normally part of the command line
used in a real invocation.

This clarifies that requirement, and provides an example.

Fix regression introduced in 749ddc14.

Specialised functionality for size changes with the advantage of
supporting frame size changes during frame-based multithreading.

This is mainly required for frame parameter changes during frame based
multithreading but single threaded usage profits too from avoiding
ff_MPV_common_end()/ff_MPV_common_init() cycles.

This is a preparation for supporting frame size changes during
frame-based multithreading.

Filters now use null pointers to indicate having no input/output pads,
rather than empty lists of pads. We can't assume pad is non-null
anymore.

This avoid a crash when the filter fails before config_input(),
typically with a syntax error in the next filter:
    select=gt(scene\,.4),select=fail

warning C4554: '>>' : check operator precedence for possible error; use parentheses to clarify precedence

This doesn't fix any build failure, but the smoothstreaming muxer
opens a chained ismv muxer.
Signed-off-by: Martin Storsjö <martin@martin.st>

This fixes stream copy from a format that already has incompatible
codec tags set. The chained ismv muxer exports this same codec tag
list, so set it on this one as well, to allow the caller (and
lavf common code) to set them correctly.

A quite widespread pattern in the demuxer is read a 32bit unsigned
integer and then loop till this value is reached.

Checking for EOF prevents pathological situations.

Normal get_bits() already has overread protection.

Use planar for DCT codec, interleaved for RDFT codec.

Eliminates the need for vector_fmul_scalar() in each frame.
