2014-12-05Use hybrid RD and non-RD coding flow for key frame codingJingning Han
When block size is below 16x16, the encoder swap from non-RD to RD mode for key frame coding. This largely brough back the key frame compression performance. For vidyo1 at 1000 kbps, the key frame coding statistics are changed 9978F, 34.183 dB, 36807 us -> 9838F, 35.020 dB, 61677 us As compared to the full RD case 7187F, 34.930 dB, 214470 us The overall rtc set coding performance (single key frame setting) is improved by 1.5%.

2014-12-04Use the RTC optimizations when in high bitdepth mode.Peter de Rivaz
Change 72193 made the encoder behave differently when configured with and without high bitdepth. This change means the same algorithm is used for both. Change-Id: I707a44a94afca773a9e0c2f7ebeeea83030257c5
2014-12-04vp9_ethread: the tile-based multi-threaded encoderYunqing Wang
Currently, VP9 supports column-tile encoding, which allows a frame to be encoded in multiple column tiles independently. The number of column tiles are set by encoder option "--tile-columns". This provides a way to encode a frame in parallel. Based on previous set of patches, this patch implemented the tile- based multi-threaded encoder. Each thread processes one or more tiles. Usage: For HD clips: --tile-columns=2 --threads=1/2/3/4 While using 4 threads, tests showed that the encoder achieved 2.3X - 2.5X speedup at good-quality speed 3, and 2X speedup at realtime speed 5.

2014-12-03Enable non-rd mode coding on key frame, for speed 6.Marco
For key frame at speed 6: enable the non-rd mode selection in speed setting and use the (non-rd) variance_based partition. Adjust some logic/thresholds in variance partition selection for key frame only (no change to delta frames), mainly to bias to selecting smaller prediction blocks, and also set max tx size of 16x16. Loss in key frame quality (~0.6-0.7dB) compared to rd coding, but speeds up key frame encoding by at least 6x. Average PNSR/SSIM metrics over RTC clips go down by ~1-2% for speed 6.

2014-12-03Rework coeff probability model update for rtc codingJingning Han
This commit reworks the ONE_LOOP_REDUCED coefficient probability model update process. It allows model update for every coefficient across the spectrum at a coarser resolution, instead of performing precise update only for certain subset of probability models. The overall runtime remains nearly same (<1% change) for speed -6. The compression performance is improved by 7.5% in PSNR for speed -5 and 4.57% for speed -6, respectively.

2014-11-25Adaptively adjust mode test kick-off thresholds in RTC codingJingning Han
This commit allows the encoder to increase the mode test kick-off thresholds if the previous best mode renders all zero quantized coefficients, thereby saving motion search runs when possible. The compression performance of speed -5 and -6 is down by -0.446% and 0.591%, respectively. The runtime of speed -6 is improved by 10% for many test clips. vidyo1, 1000 kbps 16578 b/f, 40.316 dB, 7873 ms -> 16575 b/f, 40.262 dB, 7126 ms nik720p, 1000 kbps 33311 b/f, 38.651 dB, 7263 ms -> 33304 b/f, 38.629 dB, 6865 ms dark720p, 1000 kbps 33331 b/f, 39.718 dB, 13596 ms -> 33324 b/f, 39.651 dB, 12000 ms mmoving, 1000 kbps 33263 b/f, 40.983 dB, 7566 ms -> 33259 b/f, 40.978 dB, 7531 ms Change-Id: I7591617ff113e91125ec32c9b853e257fbc41d90

2014-11-24vp9_ethread: modify VP9_COMP structureYunqing Wang
This patch modified struct VP9_COMP. Created a struct ThreadData to include data that need to be copied for each thread. In multiple thread case, one thread processes one tile. all threads share one copy of VP9_COMP, (refer to VP9_COMP *cpi in the code) but each thread has its own copy of ThreadData, (refer to ThreadData *td in the code). Therefore, within the scope of encode_tiles(), both cpi and td need to be passed as function parameters. In single thread case, the FRAME_COUNTS pointer in ThreadData points to "counts" in VP9_COMMON. Change-Id: Ib37908b2d8e2c0f4f9c18f38017df5ce60e8b13e
