Create SMPTE ST 12-1 timecodes based on H.264 SEI picture timing
info.

For framerates > 30 FPS, the field flag is used in conjunction with
pairs of frames which contain the same frame timestamp in S12M.
Ensure the field is properly set per the spec.

Keep alignment with vaapi mjpeg encoder.

Currently qsv (m)jpeg encoding is broken.
Regression introducing by the commit(id: c1bcd3): fix async support,
which requires the minimum async_depth to be 1, instead previous zero.
But the default async_depth of qsv (m)jpeg encoding is still initialized
(mostly) as zero.

This patch also abviously improves qsv (m)jpeg encoding performance
due to the default async_depth is changed to 4.

Any of these buffers (for both H.264 and H.265) might reasonably be
parsed using the bitstream reader, so include padding on all of them.

It should be the same as the one used for the rest of the pic_timing
structure.

64c50c0e declared support for decomposing
them but omitted to implement it; this adds an implementation.

Also do the same for end-of-stream NAL units, since they are equivalent.

There are different the RCV file format for VC-1, vc1test
just handle the case 2 now, this fix will support the case 1.
(Both of test clips come from: SMPTE Recommended Practice -
VC-1 Decoder and Bitstream Conformance). And I think I got
a older VC-1 test clip in the case 1.

It's not used, and pulls in the ffnvcodec header, which does not neccesarily have to exist to build these filters, since they include the full cuda.h.

setfield and setrange filters are kept.

Right now, HTTP Persistent connections is supported only for POSTs and PUTs.
HTTP DELETE will still open a new connection every time.

Improve encoding speed by 2% (using prores input)

avcodec/proresenc_aw : use AVframe primaries, transfert, colorspace for frame header instead of default (unknown, unknown, Rec601)

avoid color shift, on some decoding software

Doesn't seems to make speed loss
