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

2012-05-04fix vp8_ namespace issuesJohn Koleszar
Make functions only referenced from one translation unit static. Other symbols with extern linkage get a vp8/vpx prefix. Change-Id: I928c7e0d0d36e89ac78cb54ff8bb28748727834f
2012-04-24Simplifies decoder multithread synchingAttila Nagy
Increment the last_row_mb_col counter by nsync after last MB of row is ready. This way we dont need to check for last MB of row when synching. Set last MB of row ready just after row extension is done, This avoids o potential race condition whit the processing of last MB of next row. Change-Id: I19c44fd6041116ee5483be2143b4f4bfcd149eac
2012-04-23Optimizes precalculated decoder block ptrs&offsAttila Nagy
The block pointers and offset do not need to be calculated for every frame. Block internal predictors can be update once when decoder is allocated. Destination and previous buffer offsets have to be updated just when frame size is changing. Change-Id: I92ca8df0e6aaac4cc35ab890751d446760bf82e2

* changes: Eliminated reconintra_mt.c Eliminated vp8mt_build_intra_predictors_mbuv_s
2012-02-28Eliminated reconintra_mt.cScott LaVarnway
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

2012-01-30New RTCD implementationJohn Koleszar
This is a proof of concept RTCD implementation to replace the current system of nested includes, prototypes, INVOKE macros, etc. Currently only the decoder specific functions are implemented in the new system. Additional functions will be added in subsequent commits. Overview: RTCD "functions" are implemented as either a global function pointer or a macro (when only one eligible specialization available). Functions which have RTCD specializations are listed using a simple DSL identifying the function's base name, its prototype, and the architecture extensions that specializations are available for. Advantages over the old system: - No INVOKE macros. A call to an RTCD function looks like an ordinary function call. - No need to pass vtables around. - If there is only one eligible function to call, the function is called directly, rather than indirecting through a function pointer. - Supports the notion of "required" extensions, so in combination with the above, on x86_64 if the best function available is sse2 or lower it will be called directly, since all x86_64 platforms implement sse2. - Elides all references to functions which will never be called, which could reduce binary size. For example if sse2 is required and there are both mmx and sse2 implementations of a certain function, the code will have no link time references to the mmx code. - Significantly easier to add a new function, just one file to edit. Disadvantages: - Requires global writable data (though this is not a new requirement) - 1 new generated source file. Change-Id: Iae6edab65315f79c168485c96872641c5aa09d55
2012-01-06Reduced the size of Y1Dequant and friends to [128][2]Scott LaVarnway
This patch removes the local copies of the dequantize constants and implements John's idea as described in "Make a local copy of the dequantized data" commit. Change-Id: Ic6b7d681f00bf63263f71ff1e39ab2f80729e8b2
2011-12-15Moved dequant idct into commonScott LaVarnway
These functions are now used by the encoder. This is WIP with the goal of creating a common idct/add for the encoder and decoder. A boost of 1.8% was seen for the HD rt test clip used. [Tero] Added needed changes to ARM side. Change-Id: Ibbb8000be09034203d7adffc457d3c3f8b06a5bf
2011-11-25Modified the inverse walsh to output directlyScott LaVarnway
to the dqcoeff or qcoeff buffer. The encoder would populate the dc coeffs of the y blocks as a separate stage (recon_dcblock) and the decoder would use a special version of the idct. This change eliminates the extra copy and reduces the code footprint. [Tero] Added needed changes to armv6 and NEON assembly. Change-Id: I83202ffdbaf83f6e5dd69f4ba2519fcf0b13b3ba
2011-10-18Remove usage of predict buffer for decodeScott LaVarnway
Instead of using the predict buffer, the decoder now writes the predictor into the recon buffer. For blocks with eob=0, unnecessary idcts can be eliminated. This gave a performance boost of ~1.8% for the HD clips used. Tero: Added needed changes to ARM side and scheduled some assembly code to prevent interlocks. Patch Set 6: Merged (I1bcdca7a95aacc3a181b9faa6b10e3a71ee24df3) into this commit because of similarities in the idct functions. Patch Set 7: EC bug fix.

2011-09-22Merge "clamp_mvs() using the wrong motion vector information"John Koleszar
2011-09-19Fix necessary for input partitions iface to match the RTP profileStefan Holmer
These changes fixes a glitch between the RTP profile and the input partitions interface. Since there's no way for the user to know the actual number of partitions, the decoder have to read the multi_token_paritition bits also when input partitions mode is enabled. Included are also a couple of fixes for issues with independent partitions and uninitialized memory reads. Change-Id: I6f93b15287d291169ed681898ed3fbcc5dc81837
2011-09-16clamp_mvs() using the wrong motion vector informationScott LaVarnway
In the "Removed bmi copy to/from BLOCKD" commit, the copy to the bmi in BLOCKD was eliminated. The clamp_mvs() used the bmi in BLOCKD, which now contains incorrect values. This patch fixes this problem. Change-Id: I8eca1eaf4015052b0b63e90876f7ad321aba7cff
2011-08-24Removed bmi copy to/from BLOCKDScott LaVarnway
for SPLITMV and B_PRED modes. Modified code to use the bmi found in mode_info_context instead of BLOCKD. On the decode side, the uvmvs are calculated only when required, instead of every macroblock. This is WIP. (bmi should eventually be removed from BLOCKD) Small performance gains noticed for RT encodes and decodes.(VGA) Change-Id: I2ed7f0fd5ca733655df684aa82da575c77a973e7
2011-08-12Disable error concealment until first key frame is decodedStefan Holmer
When error concealment is enabled the first key frame must be successfully received before error concealment is activated. Error concealment will be activated when the delta following delta frame is received. Also fixed a couple of bugs related to error tracking in multi-threading. And avoiding decoding corrupt residual when we have multiple non-resilient partitions. Change-Id: I45c4bb296e2f05f57624aef500a874faf431a60d
2011-07-22fix sharpness bug and clean upJohann
sharpness was not recalculated in vp8cx_pick_filter_level_fast remove last_filter_type. all values are calculated, don't need to update the lfi data when it changes. always use cm->sharpness_level. the extra indirection was annoying. don't track last frame_type or sharpness_level manually. frame type only matters for motion search and sharpness_level is taken care of in frame_init move function declarations to their proper header Change-Id: I7ef037bd4bf8cf5e37d2d36bd03b5e22a2ad91db
2011-07-08New loop filter interfaceAttila Nagy
Separate simple filter with reduced no. of parameters. MB filter level picking based on precalculated table. Level table updated for each frame. Inside and edge limits precalculated and updated just when sharpness changes. HEV threshhold is constant. ARM targets use scalars and others vectors. Change works only with --target=generic-gnu All other targets have to be updated! Change-Id: I6b73aca6b525075b20129a371699b2561bd4d51c
2011-06-27Adding support for error concealment in multi-threaded decodingStefan Holmer
Also includes a couple of error concealment bug fixes: - the segment_id wasn't properly initialized when missing - when interpolating and no neighbors are found, set to zero - clear the qcoef buffer when concealing an MB Change-Id: Id79c876b41d78b559a2241e9cd0fd2cae6198f49
2011-06-15Remove redundant check for KEY_FRAME in multithreaded decoderAttila Nagy
For Intra blocks is enough to check ref_frame == INTRA_FRAME. Change-Id: I3e2d3064c7642658a9e14011a4627de58878e366
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
