* Fix building of static libs on universal-darwinJohn Koleszar2011-08-031-1/+1
| | | | | | | | | The static libs should not be built from sources during the top level of a universal build. This regression was introduced in commit 495b241fa6b03345baf2b2f39aa8c06c735fccc2, which made the static libs selectable under CONFIG_STATIC. Change-Id: I585167e17459877e0fa7fa19e1046c3703d91c97

| * Convert rc_max_intra_bitrate_pct to controlJohn Koleszar2011-07-284-24/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | Since this is the only ABI incompatible change since the last release, convert it to use the control interface instead. The member of the configuration struct is replaced with the VP8E_SET_MAX_INTRA_BITRATE_PCT control. More significant API changes were expected to be forthcoming when this control was first introduced, and while they continue to be expected, it's not worth breaking compatibility for only this change.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change implemented same idea in change "Preload reference area to an intermediate buffer in sub-pixel motion search." The changes were made to vp8_find_best_sub_pixel_step() and vp8_find_best_half _pixel_step() functions which are called when speed >= 5. Test result (using tulip clip): 1. On Core2 Quad machine(Linux) rt mode, speed (-5 ~ -8), encoding speed gain: 2% ~ 3% rt mode, speed (-9 ~ -11), encoding speed gain: 1% ~ 2% rt mode, speed (-12 ~ -14), no noticeable encoding speed gain 2. On Xeon machine(Linux) Test on speed (-5 ~ -14) didn't show noticeable speed change. Change-Id: I21bec2d6e7fbe541fcc0f4c0366bbdf3e2076aa2

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

| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
