2015-03-19Safely free all the frame buffers after all the workers finish the work.hkuang
Issue: 978 Change-Id: Ia7aa809095008f6819a44d7ecb0329def79b1117
2015-03-04Make encoder buffer allocation dynamicAdrian Grange
Frame buffers are now allocated dynamically on-demand. Entries in the reference frame map, cm->ref_frame_map, may now be set to -1 (INVALID_IDX) to indicate that there is not a valid reference buffer in that "slot". All slots in the reference frame map are now initialized to the empty state (-1) and each buffer is initialized to have a reference count of 0. Change-Id: Id1afe98de98db4ae8b2dfefed7889c3b28c68582
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.

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. VP9 frame parallel decode is >30% faster than serial decode with tile parallel threading which will makes devices play 1080P VP9 videos more easily. * frame-parallel: Add error handling for frame parallel decode and unit test for that.

2014-11-05Totally remove prev_mi in VP9 decoder.hkuang
This will save the memory and improve the decode speed due to removing unnecessary memset of big prev_mi array for all the key frames. Decoding a all key frames 1080p video shows speed improve around 2%. Change-Id: I6284a445c1291056e3c15135c3c20d502f791c10
2014-07-28Add segmentation map array for current and last frame segmentation.hkuang
The original implementation only allocates one segmentation map and this works fine for serial decode. But for frame parallel decode, each thread need to have its own segmentation map and the last frame segmentation map should be provided from last frame decoding thread. After finishing decoding a frame, thread need to serve the old segmentation map that associate with the previous decoded frame. The thread also need to use another segmentation map for decoding the current frame. Change-Id: I442ddff36b5de9cb8a7eb59e225744c78f4492d8
2014-07-17Modified frame buffer handlingAdrian Grange
This patch is the first step toward simplifying the frame buffer handling. The final goal is to have a common frame buffer handling framework for both encoder and decoder that incorporates the existing ability to use externally allocated memory. Change-Id: I2c378a4f54a39908915f46c4260e17a080db7ff1
2014-06-23Allocate buffers based on correct chroma formatAdrian Grange
The encoder currently allocates frame buffers before it establishes what the chroma sub-sampling factor is, always allocating based on the 4:4:4 format. This patch detects the chroma format as early as possible allowing the encoder to allocate buffers of the correct size. Future patches will change the encoder to allocate frame buffers on demand to further reduce the memory profile of the encoder and rationalize the buffer management in the encoder and decoder.

2013-09-11New mode_info_context storage -- undo revertScott LaVarnway
mode_info_context was stored as a grid of MODE_INFO structs. The grid now constists of pointers to MODE_INFO structs. The MODE_INFO structs are now stored as a stream (decoder only), eliminating unnecessary copies and is a little more cache friendly. Change-Id: I031d376284c6eb98a38ad5595b797f048a6cfc0d

2013-09-06New mode_info_context storageScott LaVarnway
mode_info_context was stored as a grid of MODE_INFO structs. The grid now constists of a pointer to a MODE_INFO struct and a "in the image" flag. The MODE_INFO structs are now stored as a stream, eliminating unnecessary copies and is a little more cache friendly. For the test clips used, the decoder performance improved by ~4.3% (1080p) and ~9.7% (720p). Patch Set 2: Re-encoded clips with latest. Now ~1.7% (1080p) and 5.9% (720p).
