* lavc: Rename hwaccel.h to hwconfig.hMark Thompson2020-04-26
| | | | | This already applied to decoders as well as hwaccels, and adding encoder support was going to make the name even more inaccurate.
* avcodec: Replace get_bits_long() by get_bits() where possibleMichael Niedermayer2019-12-31
| | | | Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avcodec/mjpegdec: Unify switch statementsAndreas Rheinhardt2019-09-18
| | | | | | | | | This has been forgotten in d5a3a20d. Found via PVS-Studio (see ticket #8156). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* lavc/mjpegdec: Skip unknown APPx marker on bayer imagesNick Renieris2019-09-02
| | | | | | | | Samples: - Embedded JPEG images in the DNG images here: https://www.photographyblog.com/previews/pentax_k1_photos Signed-off-by: Nick Renieris <velocityra@gmail.com>
* lavc/mjpegdec: Enable decoding of single-component bayer imagesNick Renieris2019-09-02
| | | | | | | | | 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. Signed-off-by: Nick Renieris <velocityra@gmail.com>
* lavc/mjpegdec: Decode Huffman-coded lossless JPEGs embedded in DNGsNick Renieris2019-09-02
| | | | | | | | | | | 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 without issues.

* lavc/mjpegdec: Interpret three-component Adobe transform 0 also as RGB.Carl Eugen Hoyos2018-12-18
| | | | | | While there, make a comparison with "RGB" more readable. Fixes ticket #7625.
* mjpegdec: Fill raw huffman tables with default values tooMark Thompson2018-11-18
| | | | | | These may be used by hwaccel decoders when the standard tables are not otherwise available. At the same time, clean up that code into an array so it's a little less repetitive.

* lavc/mjpeg: Add profiles for MJPEG using SOF marker codesMark Thompson2018-02-21
| | | | | | This is needed by later hwaccel code to tell which encoding process was used for a particular frame, because hardware decoders may only support a subset of possible methods.
