2016-10-21vp9_bitstream: Encode tiles in parallelVignesh Venkatasubramanian
Re-use the tile worker threads to pack the bitstream in parallel on a per-tile basis. Restricting this to real-time only for now (further testing is needed to ensure this does not make 2-pass worse in any case). BUG=webm:1309 Change-Id: I8a80da7c5089b837d0df79a5c49d5e3022dfc8ec

2015-09-25Rename display_{size,width,height} to render_*.Ronald S. Bultje
The name "display_*" (or "d_*") is used for non-compatible information (that is, the cropped frame dimensions in pixels, as opposed to the intended screen rendering surface size). Therefore, continuing to use display_* would be confusing to end users. Instead, rename the field to render_*, so that struct vpx_image can include it.

2015-09-16Add support for color-range.Ronald S. Bultje
In decoder, export (eventually) into vpx_image_t.range field. In encoder, use oxcf->color_range to set it (same way as for color_space). See issue 1059. Change-Id: Ieabbb2a785fa58cc4044bd54eee66f328f3906ce

(see I3a05cf1610679fed26e0b2eadd315a9ae91afdd6) For the test clip used, the decoder performance improved by ~2%. This is also an intermediate step towards adding back the mode_info streams. Change-Id: Idddc4a3f46e4180fbebddc156c4bbf177d5c2e0d

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
2015-02-02adjust rtc setting and thresholdYaowu Xu

2015-01-14Add encoder control for setting color spaceYaowu Xu
This commit adds encoder side control for vp9 to set color space info in the output compressed bitstream. It also amends the "vp9_encoder_params_get_to_decoder" test to verify the correct color space information is passed from the encoder end to decoder end.

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.

2014-11-25vp9_ethread: calculate and save the tok starting address for tilesYunqing Wang
Each tile's tok starting address is calculated before the encoding process. These addresses are stored so that the same calculation won't be done again in packing bit stream. Change-Id: I0a3be0301f002260c19a850303f2f73ebc47aa50
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

2014-11-14vp9_ethread: combine encoder counts in separate structYunqing Wang
Several frame counters in encoder are updated at SB level. Combine those counters and put them in a separate struct, which allows us to allocate one copy for each thread. Change-Id: I00366296a13c0ada4d8fa12f5e07728388b6cab7
2014-11-14vp9_ethread: include a pointer to mb in VP9_COMPYunqing Wang
Modified VP9_COMP struct to include MACROBLOCK *mb. This change makes it feasible in multi-thread case to allocate a mb for each thread. Change-Id: I624d6d1aa9c132362200753e5d90b581b1738d6e
