2012-12-07Moved denoiser frame copy/updates out of loopfilter threadScott LaVarnway
The loopfilter thread from the previous frame can be running while starting the current frame. cpi->Source will change during this time causing the wrong data to be copied. The refresh_x_frame flags also change, which will cause incorrect updates of the denoised buffers. Change-Id: I7d982b4fcb40a0610801332aa85f3b792c64e4c3
2012-12-06Merge "added work buffer for denoiser"Scott LaVarnway
2012-12-05added work buffer for denoiserScott LaVarnway
The denoiser was writing to LAST_FRAME buffer. If LAST_FRAME isn't being updated, the reference frame buffers were out of sync between the encoder and the denoised raw buffers. This patch resolves the discrepancy by always writing to a work buffer (INTRA_FRAME) and then copying from that buffer to any buffers that needs to be updated.

2012-11-26Updates to qp-regulate and rate correction factor.Marco Paniconi
Don't use the switch to gf_rate_correction factor when temporal layers is used (i.e., cpi->oxcf.number_of_layers > 1). In temporal layers, we prefer to avoid this as any frame (e.g., base layer frame at anchor of pattern) may update both last and golden (and possibly alt-ref), and so we would get different rate correction factors within the same layer. This change will make sure one rate correction factor exists for each layer. Also, made some other code in qp-regulate that depends on alt/golden update specific to the 1 layer case.

2012-10-09multi-res: disable intra on forced ref framesJohn Koleszar
If a reference frame is forced because of low dissimilarity, then shut off the search of intra modes. This change has mixed results. On one clip (QVGA), it hurt quality by ~1.5% with negligible speed impact. On another (VGA) it had negligible affect on quality, but a ~0.2% speed impact.

2012-10-09Merge "post-proc: deblock filter optimization"Yunqing Wang
2012-10-08post-proc: deblock filter optimizationYunqing Wang
1. Algorithm modification: Instead of having same filter threshold for a whole frame, now we allow the thresholds to be adjusted for each macroblock. In current implementation, to avoid excessive blur on background as reported in issue480(http://code.google.com/p/webm/issues/detail?id=480), we reduce the thresholds for skipped macroblocks. 2. SSE2 optimization: As started in issue479(http://code.google.com/p/webm/issues/detail?id=479), the filter calculation was adjusted for better performance. The c code was also modified accordingly. This made the deblock filter 2x faster, and the decoder was 1.2x faster overall. Next, the demacroblock filter will be modified similarly. Change-Id: I05e54c3f580ccd427487d085096b3174f2ab7e86
2012-10-08multi-res: work around reference mismatchJohn Koleszar
In some situations, believed to be an interaction between temporal scalability and dropped frames, the references available to an encoder may not be the same references available to its parent. Previously, the code tried to force the reference frame chosen by the parent to be used on this frame, even if it was disabled. This was preventing the pick mode loop from running even once, which led to a crash. Attempts to reproduce this bug locally were unsuccessful, so it is still undetermined what the underlying cause of this issue is. In the specific case that was failing, the application did not set any flags which influenced the reference selection on that frame. ref_frame_flags indicated that the golden frame was disabled, believed to be because the last frame updated the last and golden frames, so golden was shut off by default. It's not clear why this wouldn't have also been true in the lower res encoder, ie, why the lower res encoder decided to use and/or was allowed to use the golden frame. We weren't able to debug into the non-crashing lower res encoder as the crash couldn't be reproduced locally. Change-Id: Ifb265253d26963ac2afde0e20cf6792788be6af7
2012-10-03fix uninitialized value in multi-res encodingJohn Koleszar
If a parent mb is available but is intra coded, then parent_ref_mv is invalid. Check that the parent is inter coded before trying to access the parent_ref_mv. Previously the parent_ref_mv was being read from an uninitialized stack allocation, causing potential OOB reads and other undefined behavior. Change-Id: I0c93cd412a19c3a184bcf6decaa145b3a036a6c0
