4208b428c4 lavf/qsv_vpp: add frame format option 
1. Currently output format is hard-coded as NV12, thus means
   CSC is always done for not NV12 input such as P010.
   Follow original input format as default output.
2. Add an option to specify output format.

d83985ce11 avcodec/mediacodecdec: try to receive a frame after signaling EOF to the codec 
Avoids returning EAGAIN after signaling EOF to the codec in
ff_mediacodec_dec_send() so we can try to receive a frame before
returning in mediacodec_receive_frame().

This helps avoiding an extra round-trip between avcodec_send_frame() and
avcodec_receive_frame() while draining the remaining frames.

f70c397456 vaapi_encode_mjpeg: fix bad component id bug 
The compound literals assigned to "components"
only exist within the scope of the if/else
block (thanks Mark Thompson for the better
explanation).

Thus, after this if/else block, "components"
ends up pointing to an arbitrary/undefined
array.  With some compilers and depending on
optimization settings, these arbitrary values
may end up being the same value (i.e. 0 with
GNU GCC 9.x).  Unfortunately, the GNU GCC
compiler, at least, never prints any warnings
about this.

This patch fixes this issue by assigning the
constant arrays to local variables at function
scope and then pointing "components" to those
as necessary.

Fixes #7915

83f9da7768 avfilter/vf_gblur: add x86 SIMD optimizations 
The horizontal pass get ~2x performance with the patch
under single thread.

Tested overall performance using the command(avx2 enabled):
./ffmpeg -i 1080p.mp4 -vf gblur -f null /dev/null
./ffmpeg -i 1080p.mp4 -vf gblur=threads=1 -f null /dev/null
For single thread, the fps improves from 43 to 60, about 40%.
For multi-thread, the fps improves from 110 to 130, about 20%.

410a0824f0 avformat/matroskadec: Compactify structure 
Matroska EBML IDs can be only four bytes long maximally, so it is
natural to use uint32_t for them. By doing this and rearranging the
elements of the MatroskaLevel1Element structure, one can reduce the size
of said structure.

Notice that this field is not read via the generic reading process for
EBML_UINT, so one is not forced to use an uint64_t for it.
