The null demuxer does not have a backing AVIOContext.

Setting an invalid range for it makes the encoder behave inconsistently.

when hlsenc use flag second_level_segment_index,
second_level_segment_size and second_level_segment_duration,
the rename is ok but the output filename always use the old filename
so move the rename operation after the close the ts file and
before open new segment

Fixes ticket #6075.

The current condition can trigger in cases where it shouldn't, with
unexpected results.
Make sure that:
- container cropping is really based on the original dimensions from the
  caller
- those dimenions are discarded on size change

The code is still quite hacky and eventually should be deprecated and
removed, with the decision about which cropping is used delegated to the
caller.

Also, add generic code for handling cropping, so the decoders can export
just the cropping size and not bother with the rest.

Extend the width/height doxy to clarify that it should store coded
values.

Introducing enforced sync points in arbitrary places is bad for
performance. Since the vast majority of receiving code (QSV VPP or
encoders, retrieving frames through hwcontext) will do the syncing, this
change should not be visible to most callers. But bumping micro just in
case.

This is also consistent with what VAAPI hwaccel does.

We can pick the correct slice index directly from the ID3D11VideoDecoderOutputView
casted from data[3].

No need to loop through the known surfaces, we'll use the requested surface
anyway.

Hopefully fix compilation with suncc.

Fixes decoding the sample from ticket #6072 with ffmpeg.

avfilter_graph_request_oldest() does work that should be done by
either the filter or the application.

The principle of this function, calling ff_request_frame() from
outside the filter was always shaky. This version is less elegant
since it requires making special cases for each filter, but it
is more robust since it no longer calls ff_request_frame()
directly without notifying the filter.

Eventually, avfilter_graph_request_oldest() will be deprecated
for a function to just run the graph.

ff_request_frame_to_filter() and ff_filter_frame_to_filter()
are only used in avfilter.c.

Having two different functions allows to have stricter tests
and detect errors earlier.

It does not change anything for the existing filters and makes
better code fatrorization when future code will use the utility
functions.

Unlike av_frame_is_writable(), it uses the link's alloc callback,
making direct rendering possible.

The code comes from ff_filter_frame_framed(), moved with mostly
trivial changes.
