2014-11-06Remove asm offset dependenciesJohann
The obj_int_extract code is no longer worth maintaining. It creates significant issues when adapting for different build systems and no longer offers as significant of a performance benefit due to improvements in intrinsics. Source files will remain until the various third-party builds are updated. The neon fast quantizer has been moved to intrinsics. The armv6 version has been removed because so few remaining targets require it. Compilers and processors have improved significantly since the pack_tokens code was written. The assembly is no longer faster than the C code. pack_tokens were the only optimizations for the armv5te targets so the targets will be removed after the test infrastructure has been updated.

2014-09-15Remove memset of every external frame buffer.Frank Galligan
Libvpx was memseting every external frame buffer before decode. This was to work around a valgrind issue in our C loop filter. Most of the time this was not needed and we have noticed some significant performance loss on some platforms. Now we require the application to zero out the buffers if it is using external frame buffers. Change-Id: I7330d00a315e65137ed30edd5f813e8929b76242

2014-09-02Adds config opt for highbitdepth + misc. vpxDeb Mukherjee
Adds config parameter vp9_highbitdepth, to support highbitdepth profiles. Also includes most vpx level high bit-depth functions. However encode/decode in the highbitdepth profiles will not work until the rest of the code is in place. Change-Id: I34c53b253c38873611057a6cbc89a1361b8985a6

2014-07-24Remove neon version of vp8 extend bordersJohann
The code fails the unit test. Speed comparisons to the C are invalid because the code frequently didn't correctly extend the right and bottom portions of the frame. Reduce maximum frame size on ARM devices to avoid OOM Change-Id: Ia664c86406f0bb8120fd7ad401f32d0bd44994fb
2014-07-24Set and use uv_crop_[width|height]Johann
Ensure consistent border extension by rounding uv_crop_* at image creation time. Where it was rounded problems could arise with the right and bottom extensions. When padding = 32, y_width = 64, and y_crop_width = 63: (padding + width - crop_width + 1) / 2 32 + 64 - 63 + 1 should equal 32 *but* 32 + 1 + 1 equals 34 giving a right buffer of 17 instead of 16. By calculating uv_crop_* earlier we round up at the appropriate time and for the same values: (y_crop_width + 1) / 2 63 + 1 / 2 64 (padding / 2) + uv_width - uv_crop_width 16 + 16 - 16 16 Change-Id: If866cd1b63444771440edb1432280ac83875969b

2014-02-10Add get release decoder frame buffer functions.Frank Galligan
This CL changes libvpx to call a function when a frame buffer is needed for decode. Libvpx will call a release callback when no other frames reference the frame buffer. This CL adds a default implementation of the frame buffer callbacks. Currently only VP9 is supported. A future CL will add support for applications to supply their own frame buffer callbacks.

2013-11-22Fix bug in extend_frame chroma extended too farAdrian Grange
This fixes issue 667. In the case where the frame was an odd number of pixels wide or high, the border was being extended by one col or row too far. The calculation of color plane dimensions was modified to use those already computed at the time the frame buffer was allocated. Also freed the temporary scaling buffer in vpxdec to prevent a memory leak. Change-Id: Ied04bdcdfd77469731408c05da205db1a6f89bf5

2013-07-15Increase border size from 96 to 160.Ronald S. Bultje
This is required because upon downscaling, if a motion vector points partially into the UMV (e.g. all minus 1 of 64+7 pixels, i.e. 70), then we can point up to 140 pixels into the larger-resolution (2x) reference buffer UMV, which means the UMV for reference buffers in downscaling needs to be 140 rounded up to the nearest multiple of 32, i.e. 160. Longer-term, we should probably handle the UMV differently by detecting edge coverage on-the-fly and using a temporary buffer for edge extensions instead of adding 160 pixels on all sides of the image (which means a CIF image uses 3x its own area size for borders).

2013-05-16Initial version of alpha channel supportJohn Koleszar
This is a mostly-working implementation of an extra channel in the bitstream. Configure with --enable-alpha to test. Notable TODOs: - Add extra channel to all mismatch tests, PSNR, SSIM, etc - Configurable subsampling - Variable number of planes (currently always uses all 4) - Loop filtering - Per-plane lossless quantizer - ARNR support This implementation just uses the same contents as the Y channel for the A channel, due to lack of content and general pain in playing back 4 channel content. A later patch will use the actual alpha channel passed in from outside the codec. Change-Id: Ibf81f023b1c570bd84b3064e9b4b8ae52e087592

2013-05-09Subsampling aware allocs and bitstreamJohn Koleszar
Make framebuffer allocations according to the chroma subsamping factors in use. A bit is placed in the raw part of the frame header for each of the two subsampling factors. This will be moved in a future commit to make them part of the TBD feature set bits, probably only set on keyframes, etc. Change-Id: I59ed38d3a3c0d4af3c7c277617de28d04a001853
