2014-03-01Remove vp9_create_common()Yaowu Xu
The function has evolved over time, now only calls vp9_rtcd(), so this commit removes the function and changes to call vp9_rtcd() directly. Change-Id: I8cfa6190daa4b28f6f3d1e11bb3a07f9c95322bf

If show_existing_frame indicates that the decoder should display an existing (previously decoded) frame, add a check to make sure that the signaled buffer does contain a valid decoded frame. Change-Id: Iac8c686b321827414d69a3f2d0467566911bcba2

2014-02-13Merge "Removed the reset of mode_info from previous frame"Yaowu Xu
2014-02-13Removed the reset of mode_info from previous frameYaowu Xu
Prior to this commit, both encoder and decoder reset mode/mv info from previous frame in error resilient mode to ensure bitstreams are able to decode when there is loss of frame in decoder side. However, this is not necessary. This commit changed to remove the reset, so encoder can continue to use mode/mv/partition information from previously encoded frame without affecting decodeablilty under loss of frame.

2014-02-11Merge "Add get release decoder frame buffer functions."Frank Galligan
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.

2014-01-31vp9 decoder: row-based multi-threaded loopfilterYunqing Wang
Implemented parallel loopfiltering, which uses existing tile- decoding threads. Each thread works on one row, and when that row is loopfiltered, it moves to next unattended row. To ensure the correct filtering order, threads are synchronized and one superblock is filtered only if the superblocks it depends on are filtered already. To reduce synchronization overhead and speed up the decoder, we use nsync > 1 for high resolution. Performance tests: 1. on desktop: 8-tile 4k video using 8 threads, speedup: 70% - 80% 4-tile HD video using 4 threads, speedup: ~35% 2. on mobile device(Nexus 7): 4-tile 1080p video using 4 threads, speedup: 18% - 25% 4-tile 1080p video using 2 threads, speedup: 10% - 15% Change-Id: If54b4a11960dd706c22d5ad145ad94156031f36a
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>).
