2014-06-11Add non420 support to vp9_extend_frame_borders.Alex Converse
Fixes an encoder/decoder mismatch problem. Change-Id: I573b3a2b7ba2171a1a380ff201b082b084e7ade1
2014-02-28Fix unused parameters in vp9_extend_frame_bordersYaowu Xu
Change-Id: I7255b3bc47d760333f58ac4878becbcc8ad30967
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

2013-08-23yv12extend: name variables consistentlyJames Zern
- s|source -> src - dest -> dst - use verbose names in extend_plane dropping the redundant comments + light cosmetics: - join a few lines / assignments - drop some unnecessary comments & includes Change-Id: I6d979a85a0223a0a79a22f79a6d9c7512fd04532
2013-08-22vpx_scale: correct pixel spellingJames Zern
Change-Id: Idcfab16da37134f943a4314674e2e2fcbff3a0f8
2013-08-09renamed vp8_yv12_copy_y to vpx_yv12_copy_yYaowu Xu
Becuase the routine is used by both vp8 and vp9 Change-Id: I2d35b287b5bc2394865d931a27da61f4ce7edeeb
2013-07-16added missed replacementYaowu Xu
Change-Id: I2bce6f381fef0729b4dd5eb09ccb609f2eddd7ef
2013-07-15Change to extend full border only when neededYaowu Xu
This is a short term optimization till we work out a decoder implementation requiring no frame border extension. Change-Id: I02d15bfde4d926b50a4e58b393d8c4062d1be70f
2013-05-15Add vp9_extend_frame_bordersJohn Koleszar
Adds a subsampling aware border extension function. This may be reworked soon to support more than 3 planes. Change-Id: I76b81901ad10bb1e678dd4f0d22740ca6c76c43b
2013-04-03vp8: set y_crop_{width,height}John Koleszar
Update to use the new YV12_BUFFER_CONFIG structure. Change-Id: Ia64757d50cc9019d336fa622e059bf68140d0fa7
2013-03-13Fix pulsing issue with scalingJohn Koleszar
Updates the YV12_BUFFER_CONFIG structure to be crop-aware. The exiting width/height parameters are left unchanged, storing the width and height algined to a 16 byte boundary. The cropped dimensions are added as new fields. This fixes a nasty visual pulse when switching between scaled and unscaled frame dimensions due to a mismatch between the scaling ratio and the 16-byte aligned sizes.

2013-02-08Avoid allocating memory when resizing framesJohn Koleszar
As long as the new frame is smaller than the size that was originally allocated, we don't need to free and reallocate the memory allocated. Instead, do the allocation on the size of the first frame. We could make this passed in from the application instead, if we wanted to support external upscaling. Change-Id: I204d17a130728bbd91155bb4bd863a99bb99b038
2012-12-05Use 'vpx_scale' consistentlyJohann
Change-Id: I178352813d2b8702d081caf405de9dbad9af2cc3
2012-11-02vpx_scale: sync from masterJohn Koleszar
Update vpx_scale from current code in master, run style transform, fix lint warnings. Change-Id: I47eadeb5b6881d448ea3728537f9b8a5b5aac78e
2012-07-17Restyle codeJohn Koleszar
Approximate the Google style guide[1] so that that there's a written document to follow and tools to check compliance[2].

2011-03-17Increase static linkage, remove unused functionsJohn Koleszar
A large number of functions were defined with external linkage, even though they were only used from within one file. This patch changes their linkage to static and removes the vp8_ prefix from their names, which should make it more obvious to the reader that the function is contained within the current translation unit. Functions that were not referenced were removed. These symbols were identified by: $ nm -A libvpx.a | sort -k3 | uniq -c -f2 | grep ' [A-Z] ' \ | sort | grep '^ *1 ' Change-Id: I59609f58ab65312012c047036ae1e0634f795779
2010-10-27Eliminate more warnings.Timothy B. Terriberry
This eliminates a large set of warnings exposed by the Mozilla build system (Use of C++ comments in ISO C90 source, commas at the end of enum lists, a couple incomplete initializers, and signed/unsigned comparisons). It also eliminates many (but not all) of the warnings expose by newer GCC versions and _FORTIFY_SOURCE (e.g., calling fread and fwrite without checking the return values). There are a few spurious warnings left on my system: ../vp8/encoder/encodemb.c:274:9: warning: 'sz' may be used uninitialized in this function gcc seems to be unable to figure out that the value shortcut doesn't change between the two if blocks that test it here. ../vp8/encoder/onyx_if.c:5314:5: warning: comparison of unsigned expression >= 0 is always true ../vp8/encoder/onyx_if.c:5319:5: warning: comparison of unsigned expression >= 0 is always true This is true, so far as it goes, but it's comparing against an enum, and the C standard does not mandate that enums be unsigned, so the checks can't be removed.

2010-09-09Use WebM in copyright notice for consistencyJohn Koleszar
Changes 'The VP8 project' to 'The WebM project', for consistency with other webmproject.org repositories. Fixes issue #97. Change-Id: I37c13ed5fbdb9d334ceef71c6350e9febed9bbba
2010-06-18cosmetics: trim trailing whitespaceJohn Koleszar
When the license headers were updated, they accidentally contained trailing whitespace, so unfortunately we have to touch all the files again. Change-Id: I236c05fade06589e417179c0444cb39b09e4200d
