2018-11-07Unify GOP structure layout setupJingning Han
Refactor define_gf_group_structure() to unify the single-layer, multi-layer ARF, and GF only GOP structure setup. Change-Id: Iebbe9c3742fc58ae4e77b1072ebecb3ee7bd26b2

2018-11-06vp9: postencode drop frame for screen content in CBR.Jerome Jiang
Encode the next frame at max q. For layers: post_encode_drop is only check on base spatial layer, and if base is post-encoded-dropped, then whole superframe is dropped. Added API to guard postencode dropping. Turned off by default. Added unittest. BUG=b/112990050 Change-Id: I42fee279014aca616f7a4d9b582cb2bf5da2f2e7

2018-11-06vp9 screen-content: Adjustments for screen content.Marco Paniconi
Increase search area, use NSTEP, and in some cases avoid bsize below 16x16. This for base spatial layer when many blocks in the frame have motion (from scene detection analysis). Improves quality for scrolling motion. Change-Id: If77b43e738a6c43610d4727a95712667088db564

2018-11-06Modified key frame detection.Paul Wilkins
Address poor key frame detection in some content. This patch improves on poor key frame / scene cut detection observed with some test content. The content in question was letter boxed film style material and also had quite low contrast. For both 1080P and 4K multiple genuine scene cuts were being missed. The changes alter the conditions for marking a transition as a "flash" rather than a scene change. The new code still deals well with genuine flashes as observed in the "crew" test clip, without falsely flagging some of the the scene cuts in the "film" test clip. The new film test clip also had some "flash" frames caused by a lightning effect and in one case a flash occurred right before a scene change. This caused a misplacement of the key frame but has been addressed by a new clause that requires the coded error for the next frame after a candidate key frame to be lower than the current frame. The patch also changes the way in which neutral blocks (similar inter and inter error) are handled in the candidate key frame decision in a way which hopefully handles the letter boxed format better. During wider testing some film clips still had missed key frames but this patch does improve things. In the case of the initial test clip the encoder correctly marks all 3 scene cuts vs 0 before the patch. Testing with our standard (mainly short single kf) derf and NF test clips is neutral.

2018-11-05vp8 dec: only compute ref frame buffer pointer for non intraJerome Jiang
When ref frame is INTRA_FRAME, pre buffer shouldn't be used. This CL copies behavior in single thread. That should apply to multithreading case too. BUG=webm:1496 Change-Id: Ibe9ab8ea9dc664151fa7ebac529d5fd1a481b4a3

Found with clang-tidy. This value is unused in libvpx. There is an existing test which ensures this is not used: test/encode_api_test.cc: EXPECT_EQ(VPX_CODEC_INVALID_PARAM, vpx_codec_enc_config_default(kCodecs[i], &cfg, 1)); Change-Id: I94bd0663c6652b4267204c02c3921972c854d0b0
