2012-02-17Merge "Fix incorrect use of uv eobs in intra modes"Yunqing Wang
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

2012-02-09max_sad check is not always implementedJohann
As an optimization some architectures use the max_sad argument to break out early from the SAD. Pass in INT_MAX instead of 0 to prevent this. Change-Id: I653c476834b97771578d63f231233d445388629d
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

Allow the application to change the frame size during encoding. This is only supported when not using lagged compress. Change-Id: I89b585d703d5fd728a9e3dedf997f1b595d0db0f
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
2012-02-06Merge "Allow to skip highest-resolution encoding in multi-resolution encoder"Yunqing Wang
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.

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

2012-01-27Hook up VP8D_GET_LAST_REF_USEDJohn Koleszar
Commit 892e23a5b introduced support for the VP8D_GET_LAST_REF_USED, but missed the mapping of the control id to the underlying function, so it was unavailable to applications. In addition, the underlying function vp8_references_buffer() is moved from common/postproc.c to decoder/onyxd_if.c as postproc.c is not built in all configurations.

* changes: Correct clamping in use of vp8_find_near_mvs() Revert "Multithreaded encoder, late sync loopfilter"
2012-01-26Correct clamping in use of vp8_find_near_mvs()John Koleszar
Commit e06c242ba introduced a change to call vp8_find_near_mvs() only once instead of once per reference frame by observing that the only effect that the frame had was on the bias applied to the motion vector. By keeping track of the sign_bias value, the mv to use could be flip-flopped by multiplying its components by -1. This behavior was subtley wrong in the case when clamping was applied to the motion vectors found by vp8_find_near_mvs(). A motion vector could be in-bounds with one sign bias, but out of bounds after inverting the sign, or vice versa. The clamping must match that done by the decoder. This change modifies vp8_find_near_mvs() to remove the clamping from that function. The vp8_pick_inter_mode() and vp8_rd_pick_inter_mode() functions instead track the correctly clamped values for both bias values, switching between them by simple assignment. The common clamping and inversion code is in vp8_find_near_mvs_bias() Change-Id: I17e1a348d1643497eca0be232e2fbe2acf8478e1

2012-01-24Revert "Multithreaded encoder, late sync loopfilter"John Koleszar
This commit is incomplete, as it does not synchronize the loop filter before returning a handle to the reconstructed frame in vpx_codec_get_preview_frame(), which can cause (false?) failures when running the test_reconstruct_buffer test. This may be related to a bug that does cause visible artifacts, which is also under investigation. This reverts commit 380d64ecb19984a1466e727244a41445ae919060.

2012-01-20Overhauling the thresholds and mixing proportions for mfqe postprocessor.Deb Mukherjee
Makes the thresholds for the multiframe quality enhancement module depend on the difference between the base quantizers. Also modifies the mixing function to weigh the current low quality frame less if the difference in quantizer is large. With the above modifications mfqe works well for both scalable patterns as well as low quality key frames. Change-Id: If24e94f63f3c292f939eea94f627e7ebfb27cb75
