2020-05-28Add extra check / unit test to SetExternalGroupOfPicturesMap()angiebird
Let SetExternalGroupOfPicturesMap() modify the gop_map_ to satisfy the following constraints. 1) Each key frame position should be at the start of a gop. 2) The last gop should not use an alt ref. Add unit test for SetExternalGroupOfPicturesMap() Change-Id: Iee9bd238ad0fc5c2ccbf2fbd065a280c854cd718

2020-05-26Make SetExternalGroupOfPicture support no arf modeangiebird
Rename external_arf_indexes by gop_map Use kGopMapFlagStart to indicate the start of a gop in the gop_map. Use kGopMapFlagUseAltRef to indicate whether to use altref in the gop_map. Change-Id: I743e3199a24b9ae1abd5acd290da1a1f8660e6ac
2020-05-26Add GOP_COMMANDangiebird
Send GOP_COMMAND to vp9 for setting gop decisions on the fly. GOP_COMMAND has three members. use: use this command to set gop or use vp9's gop decision. show_frame_count: number of show frames in this gop. use_alt_ref: use alt ref frame or not. Move the logic of processing external_arf_indexes_ from get_gop_coding_frame_num() to GetGopCommand() and GetCodingFrameNumFromGopMap(). Change-Id: Ic1942c7a4cf6eecdf3507864577688350c7ef0cf

2020-05-15vp9-svc: Fix key frame update refresh simulcast flexible svcMarco Paniconi
For flexible svc in simulcast mode: don't allow refresh of all reference slots on key frame. Which slots to update should be based on the user flags. Change-Id: I3597c61ebcdfed2055bbdffec7ce701fad892744

2020-05-13vp9-rtc: Increase thresh for scene detectionMarco Paniconi
For CBR screen content mode. Makes it more robust to false detections. Change-Id: Icad89adb6f79b530b589bba2c71ba88ee5088d37
2020-04-25vp9_firstpass.c: limit mv_limits with MV_MAX in motion_searchNeil Birkbeck
Currently, in rare cases on big videos (> 5K), best_mv may differ from ref_mv by more than the allowable MV_MAX. Intersect mv_limits with those bound by MV_MAX before diamond search. We could use vp9_set_mv_search_range, but that seems a bit more constrained than the bug I encountered (e.g., MAX_FULL_PEL_VAL < MV_MAX / 8). Change-Id: I2c6563c05039d6ee05edf642665faaccf51787d4

2020-04-19vp9-rtc: Some speedups to speed 5 real-time modeMarco Paniconi
Enable use_source_sad at speed 5 and use it to condition min_partition_size in nonrd_select_partition. Also disable checking rectangular partitions in nonrd_pick_partition for speed >= 5. ~5-8% speedup for HD clip on x86. bdrate loss of ~1% on rtc set.

2020-04-09vp9-rtc: Fix to disable_16x16part speed featureMarco Paniconi
Condition on current_video_frame count, as the avg_frame_qindex needs some time to settle. Fixes psnr test failures. Change-Id: I462c45250becb55b72b6ffe2b7087094d6d58a01

2020-04-08vp9-rtc: Disable nonrd_keyframe for SVC, speed >=8Marco Paniconi
For speed >= 8: disable nonrd_keyframe SVC with spatial_layers > 1. In this case having base spatial layer key frame with higher quality (hybrid mode search) is beneficial, without too much cpu cost (since its on lowest spatial layer). Change-Id: Iff7c43aed4e808603d8abdedb6eb5d2c9c8ecb8d
2020-04-08vp9-rtc: Set disable_16x16part for low-resoln high QMarco Paniconi
Only affects variance partition at low-resoln, speed 6,7 real-time mode. At very high Q better to save bits from the split to 8x8. bdrate gain ~3% on rtc_derf at very low bitrates Change-Id: I94ee58e67d5ba6277cbab8f8dd9ea45b035c82b5
2020-04-07Merge "vp9: add rate control interface for RTC"Jerome Jiang
2020-04-06vp9: add rate control interface for RTCJerome Jiang
Add vp9 RTC rate control without creating encoder, to allow external codecs to use vp9 rate control. A new library (libvp9rc.a) will be built. Applications using this interface must be linked with the library. BUG=1060775 Change-Id: Ib3e597256725a37d2d104e1e1a1733c469991b03
2020-04-01x86_abi_support: use correct hidden syntaxJohann
Chromium needs :function hidden and the space between the symbol and the colon removed, at least for nasm. This matches x86inc.asm. BUG=webm:1679 Change-Id: Ie47bb75d44d3130791639cbf4e2ebe019e2d686e
2020-03-31vp9-rtc: Refactor postencode for 1 passMarco Paniconi
Move some code for 1 pass, that is not directly related to rate control, out of the postencode. This avoids the need of extra flag for the RC interface in: https://chromium-review.googlesource.com/c/webm/libvpx/+/2118915 Change-Id: I3992ea8255196a762c1174c35dd7dcc9b01d317e

2020-03-20Optimize vp9_get_sub_block_energy.Clement Courbet
Because energy scaling is non-decreasing, we can work on the variance and scale after the loop. This avoids costly computations (in particular, log()) within the loop. We've measured that we spend 0.8% of our total time computing the log. Change-Id: I302fc0ecd9fd8cf96ee9f31b8673e82de1b2b3e2

2020-03-03vp9-svc: Allow for dynamic resize for single layer SVCMarco Paniconi
Make internal dynamic resize work for SVC mode when single layer SVC is running (i.e, other layers are dropped due to 0 bitrate). Added unittest. Change-Id: Icf03e1f276d9c4ba2734c87c927f7881c6b0a116

2020-03-02Add init/update_frame_indexes()angiebird
We will init and update current_video_frame and current_frame_coding_index in the functions. So it's easier to keep track of when the frame indexes are updated. Change-Id: Id6ba46643f8923348bb4f81c5dd9ace553244057
2020-03-02Add GetVectorData()angiebird
It's necessary to get data pointer from a vector sometimes. This function will guarantee that the data pointer is nullptr if the vector is empty. Change-Id: I156308bcb193fe404452d3cd3b24b3f80c3c3727
