2010-10-27fix implicit declarationsJohann
ARM used to explicitly remove this file from the build. With the RTCD changes, that's no longer possible. These errors also exist for x86 w/o RTCD, but that's not the default configuration Change-Id: I3e10e5553ddf3278e8d3c9365ca6fb84f52f5066

2010-10-26Add half-pixel variance RTCD functionsJohn Koleszar
NEON has optimized 16x16 half-pixel variance functions, but they were not part of the RTCD framework. Add these functions to RTCD, so that other platforms can make use of this optimization in the future and special-case ARM code can be removed. A number of functions were taking two variance functions as parameters. These functions were changed to take a single parameter, a pointer to a struct containing all the variance functions for that block size. This provides additional flexibility for calling additional variance functions (the half-pixel special case, for example) and by initializing the table for all block sizes, we don't have to construct this function pointer table for each macroblock.

2010-10-26make vp8_recon16x16mb{,y} RTCD functionsJohn Koleszar
ARM NEON has a platform specific version of vp8_recon16x16mb, though it's just a stub to extract the various parameters from the MACROBLOCKD struct and pass them to vp8_recon16x16mb_neon(). Using that function's prototype directly will be a better long term solution, but it's quite an invasive change. Change-Id: I04273149e2ade34749e2d09e7edb0c396e1dd620
2010-10-26make arm hex search the generic implementationJohn Koleszar
The ARM version of vp8_hex_search() is a faster implementation of the same algorithm. Since it doesn't use any ARM specific code, it can be made the default implementation. This removes a linking error. Change-Id: I77d10f2c16b2515bff4522c350004e03b7659934

2010-10-26arm: move unrolled loops back to generic codeJohn Koleszar
Some of the ARM functions differed from their generic counterparts only by unrolling their loops. Since this change may be useful on other platforms, or might even supercede the looped version in the generic case, move it back to the generic file. This code is left under #if ARCH_ARM for now, but it may be worth considering a different (possibly new) conditional for these. If it turns out that this should be runtime selectable, these functions will have to move to the RTCD infrastructure. Don't want to take that step at this time without more profile data.

2010-10-26arm: remove duplicate functionsJohn Koleszar

2010-10-25reuse common loopfilter codeJohann
there were four versions for the regular and macroblock loopfilters: horizontal [y|uv] vertical [y|uv] this moves all the common code into 2 functions: vp8_loop_filter_neon vp8_mbloop_filter_neon this provides no gain in performance. there's a bit of jitter, but it trends down ~0.25-0.5%. however, this is a huge gain maintenance. also, there is the potential to drop some stack usage in the macroblock loopfilter.

2010-10-25Add runtime CPU detection support for ARM.Timothy B. Terriberry
The primary goal is to allow a binary to be built which supports NEON, but can fall back to non-NEON routines, since some Android devices do not have NEON, even if they are otherwise ARMv7 (e.g., Tegra). The configure-generated flags HAVE_ARMV7, etc., are used to decide which versions of each function to build, and when CONFIG_RUNTIME_CPU_DETECT is enabled, the correct version is chosen at run time. In order for this to work, the CFLAGS must be set to something appropriate (e.g., without -mfpu=neon for ARMv7, and with appropriate -march and -mcpu for even earlier configurations), or the native C code will not be able to run. The ASFLAGS must remain set for the most advanced instruction set required at build time, since the ARM assembler will refuse to emit them otherwise. I have not attempted to make any changes to configure to do this automatically. Doing so will probably require the addition of new configure options. Many of the hooks for RTCD on ARM were already there, but a lot of the code had bit-rotted, and a good deal of the ARM-specific code is not integrated into the RTCD structs at all. I did not try to resolve the latter, merely to add the minimal amount of protection around them to allow RTCD to work. Those functions that were called based on an ifdef at the calling site were expanded to check the RTCD flags at that site, but they should be added to an RTCD struct somewhere in the future. The functions invoked with global function pointers still are, but these should be moved into an RTCD struct for thread safety (I believe every platform currently supported has atomic pointer stores, but this is not guaranteed). The encoder's boolhuff functions did not even have _c and armv7 suffixes, and the correct version was resolved at link time. The token packing functions did have appropriate suffixes, but the version was selected with a define, with no associated RTCD struct. However, for both of these, the only armv7 instruction they actually used was rbit, and this was completely superfluous, so I reworked them to avoid it. The only non-ARMv4 instruction remaining in them is clz, which is ARMv5 (not even ARMv5TE is required). Considering that there are no ARM-specific configs which are not at least ARMv5TE, I did not try to detect these at runtime, and simply enable them for ARMv5 and above. Finally, the NEON register saving code was completely non-reentrant, since it saved the registers to a global, static variable. I moved the storage for this onto the stack. A single binary built with this code was tested on an ARM11 (ARMv6) and a Cortex A8 (ARMv7 w/NEON), for both the encoder and decoder, and produced identical output, while using the correct accelerated functions on each. I did not test on any earlier processors. Change-Id: I45cbd63a614f4554c3b325c45d46c0806f009eaa

2010-10-22Improve handling of invalid frames.Timothy B. Terriberry
The code was not checking for frame sizes smaller than 3 bytes, and the partition size checks might have failed if the input buffer was within 16MB of the top of the heap. In addition, the reference count on the current frame buffer was not being decremented on error, so after a small number of errors, no new frame buffer could be found and it would run off the list of them.

2010-10-21Convert [4][4] matrices to [16] arrays.Timothy B. Terriberry
Most of the code that actually uses these matrices indexes them as if they were a single contiguous array, and coverity produces reports about the resulting accesses that overflow the static bounds of the first row. This is perfectly legal in C, but converting them to actual [16] arrays should eliminate the report, and removes a good deal of extraneous indexing and address operators from the code.

2010-10-21Merge "Move firstpass motion map to stats packet"John Koleszar
2010-10-21Move firstpass motion map to stats packetJohn Koleszar
The first implementation of the firstpass motion map for motion compensated temporal filtering created a file, fpmotionmap.stt, in the current working directory. This was not safe for multiple encoder instances. This patch merges this data into the first pass stats packet interface, so that it is handled like the other (numerical) firstpass stats. The new stats packet is defined as follows: Numerical Stats (16 doubles) -- 128 bytes Motion Map -- 1 byte / Macroblock Padding -- to align packet to 8 bytes The fpmotionmap.stt file can still be generated for debugging purposes in the same way that the textual version of the stats are available (defining OUTPUT_FPF in firstpass.c) Change-Id: I083ffbfd95e7d6a42bb4039ba0e81f678c8183ca

Instead of doing 8-bit data unpack and 16-bit subtraction, use psubb to do 16 8-bit subtractions and pcmpgtb to preserve the sign information. This does not bring noticable gain since these functions are not called frequently. Change-Id: I90a0dfaa3db9d422e4ada324076596ffb178548e

2010-10-15change to make use of more trellis quantizationYaowu Xu
when a subsequent frame is encoded as an alt reference frame, it is unlikely that any mb in current frame will be used as reference for future frames, so we can enable quantization optimization even when the RD constant is slightly rate-biased. The change has an overall benefit between 0.1% to 0.2% bit savings on the test sets based on vpxssim scores. Change-Id: I9aa7bc5cd573ea84e3ee655d2834c18c4460ceea
