2012-02-29Packing bitstream on-the-fly with delayed context updatesAttila Nagy
Produce the token partitions on-the-fly, while processing each MB. Context is updated at the beginning of each frame based on the previoud frame's counters. Optimally encoder outputs partitions in separate buffers. For frame based output, partitions are concatenated internally. Limitations: - enabled just in combination with realtime-only mode - number of encoding threads has to be equal or less than the number of token partitions. For this reason, by default the encoder will do 8 token partitions. - vpxenc supports partition output (-P) just in combination with IVF output format (--ivf) Performance: - Realtime encoder can be up to 13% faster (ARM) depending on the number of threads and bitrate settings. Constant gain over the 5-16 speed range. - Token buffer reduced from one frame to 8 MBs Quality: - quality is affected by the delayed context updates. This again dependents on input material, speed and bitrate settings. For VC style input the loss seen is up to 0.2dB. If error-resilient=2 mode is used than the effect of this change is negligible. Example: ./configure --enable-realtime-only --enable-onthefly-bitpacking ./vpxenc --rt --end-usage=1 --fps=30000/1000 -w 640 -h 480 --target-bitrate=1000 --token-parts=3 --static-thresh=2000 --ivf -P -t 4 -o strm.ivf tanya_640x480.yuv Change-Id: I127295cb85b835fc287e1c0201a67e378d025d76

Reworked the code to use vp8_build_intra_predictors_mby_s, vp8_intra_prediction_down_copy, and vp8_intra4x4_predict_d_c functions instead. vp8_intra4x4_predict_d_c is a decoder-only version of vp8_intra4x4_predict. Future commits will fix this code duplication. Change-Id: Ifb4507103b7c83f8b94a872345191c49240154f5

2012-02-28Only do uv intra-mode evaluation when intra mode is checkedYunqing Wang
When we encode slide-show clips, for the majority of the time, only ZEROMV mode is checked, and all other modes are skipped. This change delayed uv intra-mode evaluation until intra mode is actually checked. This gave big performance gain for slide-show video encoding (2nd pass gain: 18% to 28%). But, this change doesn't help other types of videos. Also, zbin_mode_boost is adjusted in mode-checking loop, which causes bitstream mismatch before/after this change when --best or --good with --cpu-used=0 are used.

2012-02-22Remove the frame rate factor for key frame size.Marco Paniconi
When temporal layers is used (i.e., number_of_layers > 1), we don't use the frame rate boost for setting the key frame target size. The factor was forcing the target size to be always at its minimum (2* per_frame_bandwidth) for low frame rates (i.e., base layer frame rate). Generally we should modify or remove this frame rate factor; for now we turn if off for number_of_layers > 1. Change-Id: Ia5acf406c9b2f634d30ac2473adc7b9bf2e7e6c6

2012-02-17Fix incorrect use of uv eobs in intra modesYunqing Wang
In vp8_rd_pick_inter_mode(), if total of eobs is zero, rate needs to be adjusted since there are no non-zero coefficients for transmission. The uv intra eobs calculated in rd_pick_intra_mbuv_mode() need to be saved before they are overwritten by inter-mode eobs. Change-Id: I41dd04fba912e8122ef95793d4d98a251bc60e58
2012-02-17Update encoder mb_skip_coeff and prob_skip_false calculationAttila Nagy
mode_info_context->mbmi.mb_skip_coeff has to always reflect the existence or not of coeffs for a certain MB. The loopfilter needs this info. mb_skip_coeff is either set by the vp8_tokenize_mb or has to be set to 1 when the MB is skipped by mode selection. This has to be done regardless of the mb_no_coeff_skip value. prob_skip_false is needed just when mb_no_coeff_skip is 1. No need to keep count of both skip_false and skip_true as they are complementary (skip_true+skip_false = total_mbs) Change-Id: I3c74c9a0ee37bec10de7bb796e408f3e77006813

2012-02-16decoder: reset segmentation map on keyframesJohn Koleszar
Refactoring some of the mode decoding logic introduced a bug where the segmentation maps would not be properly reset on keyframes. http://code.google.com/p/webm/issues/detail?id=378 The text of the bug is somewhat misleading as I initially read it to imply the bug was present in v0.9.7-p1 (Cayuga), but note the text "master", which indicates this was something subsequent. This issue bisects back to v0.9.7-p1-84-ga99c20c, so unfortunately it was broken during the Duclair release. Thanks to Alexei Leonenko for investigating the root cause.

2012-02-16Multithreaded encoder, late sync loopfilterAttila Nagy
Second shot at this... Sync with loopfilter thread as late as possible, usually just at the beginning of next frame encoding. This returns control to application faster and allows a better multicore scaling. When PSNR packets are generated the final filtered frame is needed imediatly so we cannot delay the sync. Same has to be done when internal frame is previewed. Change-Id: I64e110c8b224dd967faefffd9c93dd8dbad4a5b5

2012-02-09Fix variance overflowJohann
In the variance calculations the difference is summed and later squared. When the sum exceeds sqrt(2^31) the value is treated as a negative when it is shifted which gives incorrect results. To fix this we cast the result of the multiplication as unsigned. The alternative fix is to shift sum down by 4 before multiplying. However that will reduce precision. For 16x16 blocks the maximum sum is 65280 and sqrt(2^31) is 46340 (and change). PPC change is untested. Change-Id: I1bad27ea0720067def6d71a6da5f789508cec265

2012-02-07Align internal mfqe framebuffer dimensionsJohn Koleszar
MFQE postproc crashed with stream dimensions not a multiple of 16. The buffer was memset unconditionally, so if the buffer allocation fails we end up trying to write to NULL. This patch traps an allocation failure with vpx_internal_error(), and aligns the buffer dimensions to what vp8_yv12_alloc_frame_buffer() expects. Change-Id: I3915d597cd66886a24f4ef39752751ebe6425066

2012-02-03Allow to skip highest-resolution encoding in multi-resolution encoderYunqing Wang
Sometimes, a user doesn't have enough bandwidth to send high-resolution (i.e. HD) video even though the camera catches HD video. This change allowed users to skip highest-resolution encoding by setting that level's target bit rate to 0. To test it, modify the following line in vp8_multi_resolution_encoder.c. unsigned int target_bitrate[NUM_ENCODERS]={1400, 500, 100}; To skip the highest-resolution level, change it to unsigned int target_bitrate[NUM_ENCODERS]={0, 500, 100}; To skip the first and second highest resolution levels, change it to unsigned int target_bitrate[NUM_ENCODERS]={0, 0, 100}; This change also fixed a small problem in mapping, which slightly helped quality and performance.
