2011-04-08Error accumulator stats bug.Paul Wilkins
The error accumulator stats values cpi->prediction_error and cpi->intra_error were being populated with rd values not distortion values. These are only "currently" used in a limited way for RT compress key frame detection. Change-Id: I2702ba1cab6e49ab8dc096ba75b6b34ab3573021

2011-04-04Merge "support obj_int_extract on cygwin"John Koleszar
2011-04-01Use full-pixel MV in mvsadcost calculationYunqing Wang
MV sad cost error is only used in full-pixel motion search, which only need full-pixel resolution instead of quarter-pixel resolution. This change reduced mvsadcost table size, and removed unneccessary pamameter passing since this table is constant once it is generated. Change-Id: I9f931e55f6abc3c99011321f1dfb2f3562e6f6b0
2011-04-01support obj_int_extract on cygwinJohann
cygwin doesn't support _sopen. drop down to the lowest common denominator and merge main for all platforms. this also opens the door for supporting multiple object formats with a single binary. Change-Id: I7cd45091639d447434e6d5db2e19cfc9988f8630

rather than look up rc in the zig zag table, embed it in the macro. this also allows us to shuffle some values in the macro and keep *d in rsi gains of about the same order as the obj_int_extract implementation: ~2% Change-Id: Ib7252dd10eee66e0af8b0e567426122781dc053d

2011-04-01Wrapper function removed from vp8_subtract_b_neon function callTero Rintaluoma
Address calculations moved from encodemb_arm.c file to neon optimized assembly function to save cycles in function calls. - vp8_subtract_b_neon_func replaced with vp8_subtract_b_neon that contains all needed address calculations - unnecessary file encodemb_arm.c removed - consistent with ARMv6 optimized version Change-Id: I6cbc1a2670b56c2077f59995fcf8f70786b4990b

* changes: Generate a vpx.pc file for pkg-config. Export the version string as a makefile variable.
2011-03-30Generate a vpx.pc file for pkg-config.Ralph Giles
Rules are added to libs.mk to generate a vpx.pc, which is installed as pkgconfig/vpx.pc under the target library directory. This also requires the install path prefix be exported directly in config.mk. Some systems use a tool called pkg-config to query information about intalled libraries or other resources, based on database files provided by the packages themselves at install time. Providing such a file for libvpx simplifies integration with other build systems, and provides an easy avenue for developers to test against their own builds of the library.

2011-03-30Export the version string as a makefile variable.Ralph Giles

2011-03-30vpxenc: die on realloc failuresJohn Koleszar
Identified as a possible cause of issue #308, the code was silently ignoring realloc failures, which would lead to corruption, memory leaks, and likely a crash. The best we can do in this case is die gracefully. Change-Id: Ie5f6a853d367015be5b9712bd742778f3baeefd9

2011-03-29ARMv6 optimized subtract functionsTero Rintaluoma
Adds following ARMv6 optimized functions to encoder: - vp8_subtract_b_armv6 - vp8_subtract_mby_armv6 - vp8_subtract_mbuv_armv6 Gives 1-5% speed-up depending on input sequence and encoding parameters. Functions have one stall cycle inside the loop body on Cortex pipeline. Change-Id: I19cca5408b9861b96f378e818eefeb3855238639

2011-03-21Remove unused vp8_get4x4sse_cs_mmx declarationJohn Koleszar
This declaration did not match the prototype_sad() prototype, but was unused in this translation unit, so it is removed instead. Fixes issue 290. Change-Id: I168854f88a85f73ca9aaf61d1e5dc0f43fc3fdb3

2011-03-18Fix multithreaded encoding for 1 MB wide frameAttila Nagy
Thread synchronization was not correct when frame width was 1 MB. Number of allocated encoding threads is limited by the sync_range. There is no point having more because each thread lags sync_range MBs behind the thread processing the row above. http://code.google.com/p/webm/issues/detail?id=302 Change-Id: Icaf67a883beecc5ebf2f11e9be47b6997fdf6f26
2011-03-17Increase static linkage, remove unused functionsJohn Koleszar
A large number of functions were defined with external linkage, even though they were only used from within one file. This patch changes their linkage to static and removes the vp8_ prefix from their names, which should make it more obvious to the reader that the function is contained within the current translation unit. Functions that were not referenced were removed. These symbols were identified by: $ nm -A libvpx.a | sort -k3 | uniq -c -f2 | grep ' [A-Z] ' \ | sort | grep '^ *1 ' Change-Id: I59609f58ab65312012c047036ae1e0634f795779
2011-03-17Set bounds from the array when iterating mmaps.Ralph Giles
The mmap allocation code in vp8_dx_iface.c was inconsistent. The static array vp8_mem_req_segs defines two descriptors, but only the first is real. The second is a sentinel and isn't actually allocated, so vpx_codec_alg_priv is declared with mmaps[NELEMENTS(vp8_mem_req_segs)-1]. Some functions use this reduced upper bound when iterating though the mmap array, but these two functions did not. Instead, this commit calls NELEMENTS(...->mmaps) to directly query the bounds of the dereferenced array. This fixes an array-bounds warning from gcc 4.6 on vp8_xma_set_mmap.
