* avcodec/omx: fix xFramerate calculationAman Gupta2019-09-02
| | | | | | | | | | | Integer overflow in the Q16 framerate calculation was sending invalid values to the OMX encoder. On the RPI4, this manifested as bitrate controls being ignored on video streams with 60000/1001 framerates. Video streams with 30000/1001 framerates were not affected.

* lavc/tiff: Enable decoding of LinearRaw imagesNick Renieris2019-09-02
| | | | | | | | | | | | | "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: - http://www.rawsamples.ch/raws/nikon/SCANNER_NIKON_LS5000.DNG 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/tiff: Fix edge case with full-length/width tilesNick Renieris2019-09-02
| | | | | | | | | 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>
* lavc/jpegtables: Handle multiple mappings to the same valueNick Renieris2019-09-02
| | | | | | | | | | | | | | | | | | | 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>
* 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.

* libavcodec/amfenc: Vulkan initialization support for encoder.OvchinnikovDmitrii2019-08-27
| | | | | | | | | | | | | | | | | | Added linux support for amf encoder through vulkan. To use h.264(AMD VCE) encoder on linux amdgru-pro version 19.20+ and amf-amdgpu-pro package(amdgru-pro contains, but does not install automatically) are required. This driver can be installed using amdgpu-pro-install script in official amd driver archive. Initialization of amf encoder occurs in this order: 1) trying to initialize through dx11(only windows) 2) trying to initialize through dx9(only windows) 3) trying to initialize through vulkan Only Vulkan initialization available on linux.
