Nick Renieris	40abff05d2	lavc/mjpegdec: Decode Huffman-coded lossless JPEGs embedded in DNGs 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.
