2015-01-05Properly validate data sizeYaowu Xu
With "show_existing_frame" frames: Minimum data size for profile 0 and 1 is 1 byte (8bits) Minimum data size for profile 2 and 3 is 2 bytes (9bits) Otherwise: Minimum data size is 8 bytes. This resolves the VP9 failure in fuzzing test build #56. Change-Id: I146d9d37688f535dd68d24aacc76d464ccffdf04
2014-12-15Revert "Revert "Add support for setting byte alignment.""Frank Galligan
This reverts commit 91471d6aad285ff10e7582e485d8adadd1986fe2. Fixes the compile issues if post_proc is enabled. Change-Id: Ib40a15ce2c194f9b5adfa65a17ab01ddf60f5a59
2014-12-15Revert "Add support for setting byte alignment."Paul Wilkins
Fails to compile. Bad calls to vp9_alloc_frame_buffer and vp9_realloc_frame_buffer in postproc.c This reverts commit 399823b6f50fb7465f62822d1395e2192e7b07fc. Change-Id: I29f0e173f8e185d3a303cfdb17813e1eccb51e3a
2014-12-12Add support for setting byte alignment.Frank Galligan
Add support for setting byte alignment on the Y, U, and V plane of the reference buffers. The byte alignment must be a power of 2, from 32 to 1024. A value of 0 sets legacy alignment. Change-Id: I7c1399622f7aa68e123646369216b32047dda73d

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
2014-08-28Removing alg_priv from vpx_codec_priv struct.Dmitry Kovalev
In order to understand memory layout consider the declaration of the following structs. The first one is a part of our API: struct vpx_codec_ctx { // ... struct vpx_codec_priv *priv; }; The second one is defined in vpx_codec_internal.h: struct vpx_codec_priv { // ... }; The following struct is defined 4 times for encoder/decoder VP8/VP9: struct vpx_codec_alg_priv { struct vpx_codec_priv base; // ... }; Private data allocation for the given ctx: struct vpx_codec_ctx *ctx = <get> struct vpx_codec_alg_priv *alg_priv = <allocate> ctx->priv = (struct vpx_codec_priv *)alg_priv; The cast works because vpx_codec_alg_priv has a vpx_codec_priv instance as a first member 'base'.

2014-08-06Make the api behavior conform to api spec.Hangyu Kuang
When no more data is available, vpx_codec_decode should be called with NULL as data and 0 as data_sz. vpx_codec_get_frame iterates over a list of the frames available for display. The iterator storage should be initialized to NULL to start the iteration. Iteration is complete when this function returns NULL. Also change the unit test to conform to the api spec.

Separates HBD profile int two profiles (2 and 3) consistent with the highbitdepth branch. This patch is ported from the original highbitdepth branch patch: https://gerrit.chromium.org/gerrit/#/c/70460/ Two of the invalid file tests needed to be updated.

2014-07-08Fix decoder handling of intra-only framesAdrian Grange
This patch fixes bug 633: https://code.google.com/p/webm/issues/detail?id=633 The first decoded frame does not have to be a keyframe, it could be an inter-frame that is coded intra-only. This patch fixes the handling of intra-only frames. A test vector has also been added that encodes 3 intra-only frames at the start of the clip. The test vector was generated using the code in the following patch: https://gerrit.chromium.org/gerrit/#/c/70680/ Change-Id: Ib40b1dbf91aae2bc047e23c626eaef09d1860147

2014-06-23error check vp9 superframe parsingJim Bankoski
This patch insures that the last byte of a chunk that contains a valid superframe marker byte, actually has a proper superframe index. If not it returns an error. As part of doing that the file : vp90-2-15-fuzz-flicker.webm now fails to decode properly and moves to the invalid file test from the test vector suite.

2014-06-19Add superframe support for frame parallel decoding.hkuang
A superframe is a bunch of frames that bundled as one frame. It is mostly used to combine one or more non-displayable frames and one displayable frame. For frame parallel decoding, libvpx decoder will only support decoding one normal frame or a super frame with superframe index. If an application pass a superframe without superframe index or a chunk of displayable frames without superframe index to libvpx decoder, libvpx will not decode it in frame parallel mode. But libvpx decoder still could decode it in serial mode. Change-Id: I04c9f2c828373d64e880a8c7bcade5307015ce35

2014-06-13Fix out of boundary memory read in fuzz test on vpxdecJingning Han
This commit fixes frame header decoding for superframe index, to prevent out of boundary memory read triggered by fuzz test vector. It resolves a chromium security violation issue crbug.com/376802. The issue was introduced in the change: Add VPXD_SET_DECRYPTOR support to the VP9 decoder. cl-id I88f86c8ff9af34e0b6531028b691921b54c2fc48 where the buffer was read before validation check on index offset applied. A test vector is added accordingly. Change-Id: I41c988e776bbdd1033312a668e03a3dbcf44ca99
2014-06-13Delay decreasing reference count in frame-parallel decoding.hkuang
The current decoding scheme will decrease the reference count of the output frame when finish decoding. Then the application could copy the frame from the decoder buffer to application buffer. In frame-parallel decoding, a decoded frame will not be outputted until several frames later which depends on thread numbers. So the decoded frame's reference count should be decreased only after application finish copying the frame out. But due to the limitation of vpx_codec_get_frame, decoder could not know when application finish decoding. So use a index last_show_frame to release the last output frame's reference count.

2014-05-30Refactor the vp9_get_frame code for frame parallel.hkuang
In frame parallel decoding mode, there will be still several frames inside the decoder when application stop calling vpx_codec_decode to decode frames. The application will need to keep calling vpx_codec_get_frame to get all the remaining decoded frames in the decoder. Change-Id: I2ce8260a91282f045bb9a6093ff8a606b1990f14
