This reverts commit 753fd86e86ac727dccac88376260b8f54502f2a3. This also has the fix for the DoS reported in bug 1558. BUG=webm:1558 Change-Id: I65ea84e0c11d6bd40d8cb0587dfe934b3ac11dce
2018-07-11test-data.sha1: update crbug-1539.rawfileJames Zern
Use a valid frame rather than the one from the bug to avoid dealing with trailing data. The decode would fail on x86 due to read size differences in the entropy decoder.

In the process of fixing a ubsan warning: commit 738b829b8cdf079a5fa48c74a28a177c9567d212 Fix incorrect size reading the inferred check of start < end was removed.

2017-11-08vp9: Add nonref frame buffer test.Jerome Jiang
The new test will run a SVC bitstream which has non ref frames. It checks the number of buffer acquired and released to make sure all external frame buffers are released. Add a new test bitstream: vp90-2-22-svc_1280x720_1.webm which has 400 frames in total, and 1 spatial layer and 2 temporal layers. There is one non ref frame every other frame. Disabled for now.

2017-06-08vp8_decode_frame: fix oob read on truncated key frameJames Zern
the check for error correction being disabled was overriding the data length checks. this avoids returning incorrect information (width / height) for the decoded frame which could result in inconsistent sizes returned in to an application causing it to read beyond the bounds of the frame allocation.

2016-08-23vp8: fix decoder crash with invalid leading keyframesJames Zern
decoding the same invalid keyframe twice would result in a crash as the second time through the decoder would be assumed to have been initialized as there was no resolution change. in this case the resolution was itself invalid (0x6), but vp8_peek_si() was only failing in the case of 0x0. invalid-vp80-00-comprehensive-018.ivf.2kf_0x6.ivf tests this case by duplicating the first keyframe and additionally adds a valid one to ensure decoding can resume without error.

2015-01-30Try again to merge branch 'frame-parallel' into master branch.hkuang
In frame parallel decode, libvpx decoder decodes several frames on all cpus in parallel fashion. If not being flushed, it will only return frame when all the cpus are busy. If getting flushed, it will return all the frames in the decoder. Compare with current serial decode mode in which libvpx decoder is idle between decode calls, libvpx decoder is busy between decode calls. Current frame parallel decode will only speed up the decoding for frame parallel encoded videos. For non frame parallel encoded videos, frame parallel decode is slower than serial decode due to lack of loopfilter worker thread. There are still some known issues that need to be addressed. For example: decode frame parallel videos with segmentation enabled is not right sometimes. * frame-parallel: Add error handling for frame parallel decode and unit test for that. Fix a bug in frame parallel decode and add a unit test for that. Add two test vectors to test frame parallel decode. Add key frame seeking to webmdec and webm_video_source. Implement frame parallel decode for VP9. Increase the thread test range to cover 5, 6, 7, 8 threads. Fix a bug in adding frame parallel unit test. Add VP9 frame-parallel unit test. Manually pick "Make the api behavior conform to api spec." from master branch. Move vp9_dec_build_inter_predictors_* to decoder folder. Add segmentation map array for current and last frame segmentation. Include the right header for VP9 worker thread. Move vp9_thread.* to common. ctrl_get_reference does not need user_priv. Seperate the frame buffers from VP9 encoder/decoder structure.

2014-11-06Modify the frame context memory deallocationYunqing Wang
This patch was to fix the vpxdec fuzzing3 test failure. When an error occurs, setjmp() is invoked, which calls the decoder removing routine. In multiple thread situation, other threads could try to access the frame context memory that is already deallocated, thus causing a segfault. An invalid unit test was added for this issue.

2014-07-28Fix reference frame size restrictions.Jim Bankoski
The issue was introduced by commit g9f37d14 with adding explicit restrictions on reference-frame scale factors. The restriction is checked against aligned-by-8 frame dimensions, not against original ones. So, for example, frame of 35×35 actually can refer to frame of 70×70, but the new check won't allow this. It will compare 35 vs 72 (not 70), so 2x downscale limit will be exceeded. Change-Id: Ic663693034440f64ac8312cbff9e1e773a921060
