When temporal layers is used (i.e., number_of_layers > 1), we don't use the frame rate boost for setting the key frame target size. The factor was forcing the target size to be always at its minimum (2* per_frame_bandwidth) for low frame rates (i.e., base layer frame rate). Generally we should modify or remove this frame rate factor; for now we turn if off for number_of_layers > 1. Change-Id: Ia5acf406c9b2f634d30ac2473adc7b9bf2e7e6c6

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

mode_info_context->mbmi.mb_skip_coeff has to always reflect the existence or not of coeffs for a certain MB. The loopfilter needs this info. mb_skip_coeff is either set by the vp8_tokenize_mb or has to be set to 1 when the MB is skipped by mode selection. This has to be done regardless of the mb_no_coeff_skip value. prob_skip_false is needed just when mb_no_coeff_skip is 1. No need to keep count of both skip_false and skip_true as they are complementary (skip_true+skip_false = total_mbs) Change-Id: I3c74c9a0ee37bec10de7bb796e408f3e77006813

Add the ability to specify multiple output streams on the command line. Streams are delimited by --, and most parameters inherit from previous streams. In this implementation, resizing streams is still not supported. It does not make use of the new multistream support in the encoder either. Two pass support runs all streams independently, though it's theoretically possible that we could combine firstpass runs in the future. The logic required for this is too tricky to do as part of this initial implementation. This is mostly an effort to get the parameter passing and independent streams working from the application's perspective, and a later commit will add the rescaling and multiresolution support.

Refactoring some of the mode decoding logic introduced a bug where the segmentation maps would not be properly reset on keyframes. http://code.google.com/p/webm/issues/detail?id=378 The text of the bug is somewhat misleading as I initially read it to imply the bug was present in v0.9.7-p1 (Cayuga), but note the text "master", which indicates this was something subsequent. This issue bisects back to v0.9.7-p1-84-ga99c20c, so unfortunately it was broken during the Duclair release. Thanks to Alexei Leonenko for investigating the root cause.

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

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

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
