Add skip_frame support to qsvenc. Use per-frame metadata
"qsv_skip_frame" to control it. skip_frame option defines the behavior
of qsv_skip_frame.
no_skip: Frame skipping is disabled.
insert_dummy: Encoder inserts into bitstream frame where all macroblocks
are encoded as skipped

In av1_spec.pdf page 38/669, there is a sentence below:
if ( frame_type == KEY_FRAME && show_frame ) {
for ( i = 0; i < NUM_REF_FRAMES; i++) {
RefValid[ i ] = 0
..
}
..
}
This shows that the condition of invalidating current
DPB frames should be the coming frame_type

Decoders that might use quarter pixel motion estimation
(namely MPEG-4 as well as the VC-1 family) currently
use MpegEncContext.me.qpel_(put|avg) as scratch space
for pointers to arrays of function pointers.
(MotionEstContext contains such pointers as it supports
quarter pixel motion estimation.) T
The only thing from the H.263 decoder that is reachable
by the VC-1 decoder is ff_h263_decode_init(); but it does
not even use all of it; e.g. h263dsp is unused and so are
the VLCs initialized in ff_h263_decode_init() (they amount
to about 77KB which are now no longer touched).
Notice that one cou
The MPEG-4 decoder is the only decoder based upon H.263 that
supports quarterpel motion vectors.

It is the only encoder supporting quarter samples.
This also allows to remove the qpeldsp dependency from
mpegvideo_enc.

This patch series adds swscale input/output support for the packed rgb float
formats.
A few of the filters also needed support the larger 96/128 bit packed pixel
sizes.
I also plan to eventually add lossless unscaled conversions between the planer
and packed formats.
