They correspond to the relevant fields from the packet that follows the
one where the expressions are being applied.

Bitstream filters inserted between the input and output were never drained,
resulting in packets being lost if the bsf had any buffered.

And use a single AVPacket for the entire process.
This more closely follows the suggested API usage in the doxy.

It's needed for avformat_get_mov_video_tags() and avformat_get_mov_audio_tags(),
both public symbols defined in avformat.h

The variable AVFrame *frame could be a null pointer, now add a null
pointer check to avoid dereferencing the null pointer.

ChromaForamt for mjpeg-qsv is always set to yuv420, and this will be
wrong when encode other pixel format (for example yuyv422). ChromaFormat
is changed to be adaptive to pix_fmt.

Fix: #7706. After commit 5fdcf85bbf, vaapi encoder's performance
decrease. The reason is that vaRenderPicture() and vaSyncBuffer() are
called at the same time (vaRenderPicture() always followed by a
vaSyncBuffer()). Now I changed them to be called in a asynchronous way,
which will make better use of hardware.
Async_depth is added to increase encoder's performance. The frames that
are sent to hardware are stored in a fifo. Encoder will sync output
after async fifo is full.

Add vaSyncBuffer to VAAPI encoder. Old version API vaSyncSurface wait
surface to complete. When surface is used for multiple operation, it
waits all operations to finish. vaSyncBuffer only wait one channel to
finish.

Having optionally installed headers is a bad idea as there's no way to know
if they are present or not (unless a define is added to avconfig.h, but that's
just ugly).

Also remove an unchecked av_frame_make_writable().
