2012-08-20Fix inter_zz_count calculation bugYunqing Wang
The current way of counting inter_zz_count doesn't work correctly in multi-threaded encoding. Calculating it after the frame is encoded fixed the problem. Change-Id: Ifcb1972cde950b8cc194f75c6d7b6af09e8b0e65
2012-08-14Added error checking to vp8cx_create_encoder_threads()Scott LaVarnway
Added checks for pthread_create() errors. Change-Id: Ie198ef5c14314fe252d2e02f7fe5bfacc7e16377
2012-08-01Fix potential encoder dead-lock after picture resizeAttila Nagy
The sync interval for the multithreaded encoder was considered as not changing during the encoding. This is not true if picture size is changed. The encoder could dead-lock because the main thread and the other threads were using different sync interval. Change-Id: I75232bbdbc6c02d77f830d870fd8b4e96697c64e
2012-07-27Optimizes updates of encoder block ptrsAttila Nagy
Precalculated block ptrs do not need updates during encoding. Set these at init stage. Moved the allocation of 'mt_current_mb_col' (last encoded MB on each row) to vp8_alloc_compressor_data(), so that it is correctly reallocated when frame size is changing. Change-Id: Idcdaa2d0cf3a7f782b7d888626b7cf22a4ffb5c1
2012-06-11Fix pedantic compiler warningsJohn Koleszar
Allows building the library with the gcc -pedantic option, for improved portabilty. In particular, this commit removes usage of C99/C++ style single-line comments and dynamic struct initializers. This is a continuation of the work done in commit 97b766a46, which removed most of these warnings for decode only builds. Change-Id: Id453d9c1d9f44cc0381b10c3869fabb0184d5966

2012-05-04Formalize encodeframe.c forward delclarationsJohn Koleszar
Change If4321cc5 fixed a bug caused by forward declarations not being kept in sync across C files, resulting in a function call with the wrong arguments. The commit moves the affected function declarations into a header file, along with the other symbols from encodeframe.c that were being sloppily shared.

2012-04-23Shares one set of RD costs tables between all encoding threadsAttila Nagy
RD costs were local to MACROBLOCK data and had to be copied all the time to each thread's MACROBLOCK data. Tables moved to a common place and only pointers are setup for each encoding thread. vp8_cost_tokens() generates 'int' costs so changed all types to be int (i.e. removed unsigned). NOTE: Could do some more cleaning in vp8cx_init_mbrthread_data(). Change-Id: Ifa4de4c6286dffaca7ed3082041fe5af1345ddc0
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
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

2011-11-08Fix checks in MB quantizer initializationYunqing Wang
vp8cx_mb_init_quantizer() needs to be called at least once to get all values calculated. This change added one check to decide if we could skip initialization or not. Change-Id: I3f65eb548be57580a61444328336bc18c25c085b

2011-06-23Copy macroblock data to a buffer before encoding itYunqing Wang
I got this idea from Pascal (Thanks). Before encoding a macroblock, copy it to a 16x16 buffer, and then read source data from there instead. This will help keep the source data in cache, and help with the performance. Change-Id: Id05f4cb601299150511d59dcba0ae62c49b5b757
2011-06-08Further activity masking changes:Paul Wilkins
Some further re-structuring of activity masking code. Still has various experimental switches. Supports a metric based on intra encode. Experimental comparison against a fixed activity target rather than a frame average, for altering rd and zbin. Overall the SSIM performance is similar to TT's original code but there is a much smaller PSNR hit of circa 0.5% instead of 3.2% Change-Id: I0fd53b2dfb60620b3f74d7415e0b81c1ac58c39a

2011-06-02Removed B_MODE_INFOScott LaVarnway
Declared the bmi in BLOCKD as a union instead of B_MODE_INFO. Then removed B_MODE_INFO completely. Change-Id: Ieb7469899e265892c66f7aeac87b7f2bf38e7a67
2011-06-01neon fast quantize block pairTero Rintaluoma
vp8_fast_quantize_b_pair_neon function added to quantize two adjacent blocks at the same time to improve performance. - Additional 3-6% speedup compared to neon optimized fast quantizer (Tanya VGA@30fps, 1Mbps stream, cpu-used=-5..-16) Change-Id: I3fcbf141e5d05e9118c38ca37310458afbabaa4e

2011-05-24MODE_INFO size reductionScott LaVarnway
Declared the bmi in MODE_INFO as a union instead of B_MODE_INFO. This reduced the memory footprint by 518,400 bytes for 1080 resolutions. The decoder performance improved by ~4% for the clip used and the encoder showed very small improvements. (0.5%) This reduction was first mentioned to me by John K. and in a later discussion by Yaowu. This is WIP. Change-Id: I8e175fdbc46d28c35277302a04bee4540efc8d29

2011-05-13Restructure of activity masking code.Paul Wilkins
This commit restructures the mb activity masking code to better facilitate experimentation using different metrics etc. and also allows for adjustment of the zero bin either for encode only or both the encode and mode selection stages It also uses information from the current frame rather than the previous frame and the default strength has been reduced.
