Make all the compression encodings behave the same way.

Tested with the GraphicsMagick TIFF archive and Libav generated files.

Adds a flag context_reinit to MpegEncContext to relieable keep track
of frame parameter changes which require a context reinitialization.
This is required for broken inputs which change the frame size but
error out before the context can be reinitialized.

Fixes triggering an assert in avcodec_default_release_buffer()
introduced in 1b3439b3.

Thus comparsion against int64_t value will not raise warning
(from -Wextra set) about comparsion of unsigned and signed integer

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(),

This doesn't fix any build failure, but the smoothstreaming 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.
