dbe9dbed31 lavfi/buffersink: add accessors for the stream properties.
av_buffersink_get_frame_rate() did already exist; its argument becomes const.

9488032e10 libavformat/avio: Add avio_get_dyn_buf function
This commit adds the avio_get_dyn_buf function which allows accessing
the
content of a DynBuffer without destroying it.

This is required in matroskaenc for preliminary writing (correct) mkv
headers.

Context for this change is fixing regression bug #5977.

775a8477b7 hwcontext_vaapi: add a quirk for the missing MemoryType attribute
The Intel binary iHD driver does not support the
VASurfaceAttribMemoryType, so surface allocation will fail when using
it.

a8d51bb424 hwcontext_vaapi: Add driver quirks to the hwdevice
The driver being used is detected inside av_hwdevice_ctx_init() and
the quirks field then set from a table of known device.  If this
behaviour is unwanted, the user can also set the quirks field
manually.

Also adds the Intel i965 driver quirk (it does not destroy parameter
buffers used in a call to vaRenderPicture()) and detects that driver
to set it.

32c8359093 lavc: export the timestamps when decoding in AVFrame.pts
Currently it's exported as AVFrame.pkt_pts, which is also the only use
for that field. The reason it is done like this is that lavc used to
export various codec-specific "timing" information in AVFrame.pts, which
is not done anymore.

Since it is confusing to the callers to have a separate field which is
used only for decoder timestamps and nothing else, deprecate pkt_pts and
use just AVFrame.pts everywhere.

db7968bff4 avio: Allow custom IO users to get labels for the output bytestream
This allows callers with avio write callbacks to get the bytestream
positions that correspond to keyframes, suitable for live streaming.

In the simplest form, a caller could expect that a header is written
to the bytestream during the avformat_write_header, and the data
output to the avio context during e.g. av_write_frame corresponds
exactly to the current packet passed in.

When combined with av_interleaved_write_frame, and with muxers that
do buffering (most muxers that do some sort of fragmenting or
clustering), the mapping from input data to bytestream positions
is nontrivial.

This allows callers to get directly information about what part
of the bytestream is what, without having to resort to assumptions
about the muxer behaviour.

One keyframe/fragment/block can still be split into multiple (if
they are larger than the aviocontext buffer), which would call
the callback with e.g. AVIO_DATA_MARKER_SYNC_POINT, followed by
AVIO_DATA_MARKER_UNKNOWN for the second time it is called with
the following data.
