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>

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. Signed-off-by: Nick Renieris <velocityra@gmail.com>

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. Without this, an "mjpeg_decode_dc: bad vlc: 0:0" error is thrown. In all known files, the 2 codes are mapped to symbol 0 so only that case is checked.

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 [1]: As specified in the DNG Specification - Chapter 5 Signed-off-by: Nick Renieris <velocityra@gmail.com>

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.

avio_feof() returns true both in case of actual EOF and in case of IO errors. Some demuxers (matroska) have special handling to be able to return the proper error for this exact reason, e.g.: if (avio_feof(pb)) { if (pb->error) { return pb->error; } else { return AVERROR_EOF; } } However, most of the demuxers do not, and they simply return AVERROR_EOF if avio_feof() is true, so there is a real chance that IO errors are mistaken for EOF. We might just say that the API user should always check the IO context error attribute on EOF to make sure no IO errors happened, but not even ffmpeg.c does this. It should be more intuitive to the API user if we simply return the IO error as the return value of av_read_frame() instead of AVERROR_EOF. Signed-off-by: Marton Balint <cus@passwd.hu>

Some security cams generate this, as well as some versions of VirtualDub and VLC so support for _reading_ such files is justified. Fixes ticket #7110. See also this discussion: https://patchwork.ffmpeg.org/patch/8744/Signed-off-by: Marton Balint <cus@passwd.hu>

After a1b4f120 the teletext PTS values were set to AV_NOPTS_VALUE if the stream of the PCR pid was discarded. What actually matters is that if we parse the PCR of the PCR PID or not, so let's use the cached discard value of the actual PCR PID instead of the stream discard value, which may be different. Also fixes ticket #7567, which was caused by the fact that teletext PTS values were not touched if the PCR pid was discarded even before a1b4f120. Signed-off-by: Marton Balint <cus@passwd.hu>

Many ffmpeg + rpi compilation guides on the internet recommend using `./configure --enable-omx --enable-omx-rpi`. This fails to find the IL OMX headers on device because the omx require_headers check happens first before the add_cflags in omx_rpi. A workaround is to use `./configure --enable-omx-rpi` only, since omx_rpi already implies omx. But because many users expect to use existing scripts and commands, we swap the order here so omx_rpi special cases are applied first. In the past this wasn't an issue because users noticed the OMX_Core.h missing error and installed libomxil-bellagio-dev. But since 76c82843, the rpi specific headers from /opt/vc/include/IL are required. Signed-off-by: Aman Gupta <aman@tmm1.net>
