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

search"
2011-07-22Preload reference area to an intermediate buffer in sub-pixel motion searchYunqing Wang
In sub-pixel motion search, the search range is small(+/- 3 pixels). Preload whole search area from reference buffer into a 32-byte aligned buffer. Then in search, load reference data from this buffer instead. This keeps data in cache, and reduces the crossing cache- line penalty. For tulip clip, tests on Intel Core2 Quad machine(linux) showed encoder speed improvement: 3.4% at --rt --cpu-used =-4 2.8% at --rt --cpu-used =-3 2.3% at --rt --cpu-used =-2 2.2% at --rt --cpu-used =-1 Test on Atom notebook showed only 1.1% speed improvement(speed=-4). Test on Xeon machine also showed less improvement, since unaligned data access latency is greatly reduced in newer cores. Next, I will apply similar idea to other 2 sub-pixel search functions for encoding speed > 4. Make this change exclusively for x86 platforms. Change-Id: Ia7bb9f56169eac0f01009fe2b2f2ab5b61d2eb2f

2011-07-21Add .size directive to ARM asm functions.Timothy B. Terriberry
This makes them show up properly in debugging tools like gdb and valgrind. Change-Id: I0c72548a1090de88ba226314e5efe63360b7e07f
2011-07-21Mark ARM asm objects as allowing a non-executable stack.Timothy B. Terriberry
This adds the magic .note.GNU-stack section at the end of each ARM asm file (when built with gas), indicating that a non-executable stack is allowed. Without this section, the linker will assume the object requires an executable stack by default, forcing an executable stack for the entire program.

2011-07-21Merge "Add improvements made in good-quality mode to real-time mode"Yunqing Wang
2011-07-20Increase chrow row alignment to 16 bytes.Timothy B. Terriberry
This is done by expanding luma row to 32-byte alignment, since there is currently a bunch of code that assumes that uv_stride == y_stride/2 (see, for example, vp8/common/postproc.c, common/reconinter.c, common/arm/neon/recon16x16mb_neon.asm, encoder/temporal_filter.c, and possibly others; I haven't done a full audit). It also uses replaces the hardcoded border of 16 in a number of encoder buffers with VP8BORDERINPIXELS (currently 32), as the chroma rows start at an offset of border/2. Together, these two changes have the nice advantage that simply dumping the frame memory as a contiguous blob produces a valid, if padded, image. Change-Id: Iaf5ea722ae5c82d5daa50f6e2dade9de753f1003

2011-07-19Revert "Disable __longjmp_chk protection"John Koleszar
This reverts commit b73a3693e581583e9ec676f4396d0c3d173e2462. This version of the check doesn't work with generic-gnu, and figuring out the correct symbol version at configure time is probably more work than this is worth. May revisit in the future.

2011-07-19Moved vp8_encode_bool into boolhuff.hScott LaVarnway
allowing the compiler to inline this function. For real-time encodes, this gave a boost of 1% to 2.5%, depending on the speed setting. Change-Id: I3929d176cca086b4261267b848419d5bcff21c02
2011-07-18Improved 1-pass CBR rate controlJohn Koleszar
This patch attempts to improve the handling of CBR streams with respect to the short term buffering requirements. The "buffer level" is changed to be an average over the rc buffer, rather than a long running average. Overshoot is also tracked over the same interval and the golden frame targets suppressed accordingly to correct for overly aggressive boosting. Testing shows that this is fairly consistently positive in one metric or another -- some clips that show significant decreases in quality have better buffering characteristics, others show improvenents in both.

2011-07-13Disable __longjmp_chk protectionJohn Koleszar
glibc implements some checking on longjmp() calls by replacing it with an internal function __longjmp_chk(), when FORTIFY_SOURCE is defined. This can be problematic when compiling the library under one version of glibc and running it under another. Work around this issue for the one symbol affected for now, before taking out the undef hammer.
