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

2014-07-15Fix show_existing_frame not decreasing frame buffer ref counter.Alexander Voronov
The issue was introduced by commit g7c43fb6. If current frame is repeated from existing-ref pool, frame buffer ref counter is not decreased, so buffer isn't released. Decoder fails being unable to allocate new frame buffer at some point. Added a test vector to verify that the condition will not recur later. Test vector was generated by the code in this patch: https://gerrit.chromium.org/gerrit/#/c/70862/ Change-Id: I8af96eb5b9670176e01a281d2e18bd458712cf78

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.

2014-06-20Validate error checking code in decoder.Jim Bankoski

2014-06-18BITSTREAM: Handle transform size and motion vectors more logically for non-420.Alex Converse
This breaks the profile 1 bitstream. Don't force non420 uv transform size to 1/4 y size. In the 4:2:0 case the chroma corresponding to a luma block is 1/4 its size. In the 4:4:4 case chroma and luma planes are the same size. Disallowing larger transforms can result in a loss of compression efficiency and is inconsistent. For sub-8x8 blocks only average corresponding motion vectors. 4:2:0 and profile 0 behavior remains unchanged. Change-Id: I560ae07183012c6734dd1860ea54ed6f62f3cae8

2014-04-08Fix decoder resolution change with tilesFrank Galligan
There was a bug with the decoder that if you started the decoder with more threads than the first frame had tile columns. Afterwards tried to decode a frame with more tile columns than the first frame, the decoder would hang. E.g. run vpxdec --threads=4. The first frame had two tile columns, then the next key frame had 4 tile columns, the decoder would hang. If you started with 4 tiles and switched to 2 tiles the decoder would be fine. The issue is that the worker the thread loop is using is stale. I added a test vector "vp90-2-14-resize-848x480-1280x720.webm" that exhibited the bug.

2014-03-28[BITSTREAM]Fix the scaling calculationYaowu Xu
For very large size video image, the scaling calculation may need use value beyond the range of int. This commit upgrade the value to 64bit to make sure the calculation do not wrap around INT_MAX. The change corrected the decoder behavior. The bug affects only very large resolution video because the scaling calculation was sufficient for image size smaller than 2^13.

2014-01-31Disable update of last_show_frame for existing frameAdrian Grange
When showing a previously decoded frame, i.e. when show_existing_frame=1, the update of the last_show_frame flag must be disabled. This is to ensure that the last_show_frame flag reflects the state of the flag for the immediately previously decoded frame rather then the value that was forced to ensure that a previously decoded frame would be displayed. This patch also adds a test vector to verify that the display_existing_frame flag works as expected. Code for generating the test vector can be found in this patch: https://gerrit.chromium.org/gerrit/#/c/68581/ (Bug originally reported by Alexander Voronov <ru.xalba@gmail.com>).
