the info can be saved in dnn operand object without regenerating again and
again,
and it is also needed for layer split/merge, and for memory reuse.
to make things step by step, this patch just focuses on c code,
the change within python script will be added later.

currently, the layer number is at the beginning of the .model file,
so we have to scan twice in python script, the first scan to get the
layer number. Only one scan needed after put the layer number at the
end of .model file.

Hey guys, if there is anything else required to progress this please let me

It’s my first patch submission to FFMpeg so not sure how long it should take.

Current default is 200kbps, which produces inconsistent
results (too high for low-res, too low for hi-res). Use
CRF instead, which will adapt. Affects vp8/vp9. Also
have VP8 use a default bitrate of 256kbps.

The current code in libavfilter/af_sofalizer.c requires
mysofa_neighborhood_init_withstepdefine function, which only appeared
in libmysofa 0.7. Use this function in configure script to bail out
early if a too old libmysofa is found in the system instead of failing
at compile time.

Also, ensure no false positives when determining DNG bayer images, by
setting them in tiff.c instead of relying on a heuristic. There's no
way to determine this just from the JPEG data, so we have to pass this
information from outside the MJPEG decoder.

From: Nick Renieris
Some JPEGs [1] have incorrect DHT entries that map 2 codes to
the same value.
The second (last) mapping does not ever actually appear in the
code stream, therefore ignoring any mappings after the first one
fixes this.

Used a technique similar to lavc/tdsc.c for invoking the MJPEG decoder.
This commit adds support for:
- DNG tiles
- DNG tile huffman lossless JPEG decoding
- DNG 8-bpp ("packed" as dcraw calls it) decoding
- DNG color scaling [1]
- LinearizationTable tag
- BlackLevel tag
From: Nick Renieris
Main image data in DNGs is usually comprised of tiles, each of which is a
Huffman-encoded lossless JPEG.
Tested for ljpeg regressions with:
`ffmpeg -f lavfi -i testsrc=d=1 -vcodec ljpeg test.avi`
`ffmpeg test.avi out.avi`
The modified code in ljpeg_decode_rgb_scan runs witho

When the height is equal to the tile length (full-height tile)
after `height % tile_length` is applied with the current code,
it results in the operating tile_length to be 0. This commit
makes this leftover logic only applies if it's necessary.

"LinearRaw" is a value that the PhotometricInterpretation tag can be set
to on DNG images that contain color information for all channels instead
of being bayer-encoded ("CFA" value).
The DNG decoder is complete enough that we can enable this now.
Sample:

Initialized to `(2 ^ BitsPerSample) - 1` as per the DNG Specification.
Also make sure that `BlackLevel < WhiteLevel`.
This fixes decoding for "X7 CinemaDNG" samples here:

Thanks for review/pushing! Waiting for Vulkan hwcontext to implement fully
hwaccelerated pipeline on linux.
