2011-06-01remove some magic weights associated with sad_per_bitYaowu Xu
sad_per_bit has been used for a number of motion vector search routines with different magic weights: 1, 1/2 and 1/4. This commit remove these magic numbers and use 1/2 for all motion search routines, also reformat a number of source code lines to within 80 column limit. Test on cif set shows overall effect is neutral on all metrics. <=0.01% Change-Id: I8a382821fa4cffc9c0acf8e8431435a03df74885

2011-05-27bug fix check frame buffer index before copyJames Berry
in onyx_if.c update_reference_frames() make sure that frame buffer indexes are not equal before preforming a buffer copy. If two frames share the same buffer the flags will already be set correctly. Change-Id: Ida9b5516d08e3435c90f131d2dc19d842cfb536e
2011-05-27Use hex search for realtime mode speed>4Yunqing Wang
Test showed using hex search in realtime mode largely speed up encoding process, and still achieves similar quality like the diamond search we have. Therefore, removed the diamond search option. Change-Id: I975767d0ec0539f9f6ed7fdfc09506e39761b66c

2011-05-25fix the mix use of errorperbit and sadperbitYaowu Xu
error_per_bit and sad_per_bit were designed as estimates of a bit worth of sum squared error and sum absolute difference respectively. Under this assumption, error_per_bit should be used in combination with 2nd order errors (variance or sum squared error) while sad_per_bit should be used in combination with 1st order SADs in motion estimation. There were a few places where sad_per_bit has been misused with variances, this commit changes to use error_per_bit for those places, also changes parameter names to properly indicate which constant is being used. On cif set, the change has a universal gain by all metrics: 0.13% by average/overall psnr and 0.1% by ssim. Change-Id: I4850fdcc3fd6886b30f784bd843f13dd401215fb

2011-05-24Merge "MODE_INFO size reduction"Scott LaVarnway
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

2011-05-19cleanup: collect twopass variablesJohn Koleszar
This patch collects the twopass specific memebers of VP8_COMP into a dedicated struct. This is a first step towards isolating the two pass rate control and aids readability by decorating these variables with the 'twopass.' namespace. This makes it clear to the reader in what contexts the variable will be valid, and is a hint that a section of code might be a good candidate to move to firstpass.c in later refactoring. There likely will be other rate control modes that need their own specific data as well. This notation is probably overly verbose in firstpass.c, so an alternative would be to access this struct through a pointer like 'rc->' instead of 'cpi->firstpass.' in that file. Feel free to make a review comment to that effect if you prefer. Change-Id: I0ab8254647cb4b493a77c16b5d236d0d4a94ca4d

2011-05-19Using partition_info instead of blockd info for splitmvScott LaVarnway
The partition_info struct contains info just for SPLITMV, so it should be used instead of BLOCKD. Eventually, I want to reduce the size of B_MODE_INFO struct found in BLOCKD, so this is the first step toward that goal. Also, since SPLITMV is not supported in vp8_pick_inter_mode(), the unnecessary mem copies and checks were removed. For rt encodes, this gave a slight performance improvement.
