Instead of finding the ref frame in output_frame() and then passing its
signature to update_crops(), pull out the logic and invoke it a second
time inside update_crops().
This may seem wasteful at present, but will actually become required in
the future, since update_crops() runs on *every* input, and needs values
specific to that input (which the signature isn't), while output_frame()
is only interested in a single input. It's much easier to just split the
logic cleanly.
Including the queue status, because these will need to be re-queried
inside output_frame_mix when that function is refactored to handle
multiple inputs.
In anticipation of a refactor which will enable multiple input support.
Note: the renderer is also input-specific because it maintains a frame
cache, HDR peak detection state and mixing cache, all of which are tied
to a specific input stream.
If the input queue is EOF, then the s->status check should already have
covered it, and prevented the code from getting this far.
If we still hit this case for some reason, it's probably a bug. Better
to hit the AVERROR_BUG branch.
Incrementing a NULL pointer is undefined behaviour,
yet this is what would happen in case trailer were NULL
before the check.

We will postpone the vpp session initialization to when input and output
frames are ready, this copy of the sequence parameters will be used to
initialize vpp session.

In ff_rtp_send_jpeg, the type is defined based on PIX_FMT and
color-range parsed in. There is limitation on current design
where need to include support newly introduced PIX_FMT such as
AV_PIX_FMT_QSV and there might be more and more in future. Hence,
retrive the sampling factor from SOF0 in JPEG compressed header
directly. This introduces flexibility to handle different type of
new codec introduced in future.

- text is now shaped using libharfbuz
- glyphs position is now accurate to 1/4 pixel in both directions
- the default line height is now the one defined in the font
Adds libharfbuzz dependency.
