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
The configure script exports the major/minor/patch version numbers, but didn't make the full version string available to Makefile recipes and rules, the way it is available to C code from vpx_version.h. Change-Id: Ic6a9d4c574a6ea66a50c928f4eedeb91d7668eb5

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

2011-03-21Allow specifying --end-usage by enum nameJohn Koleszar
Map an enum to the --end-usage values, so you can specify --end-usage=cq instead of --end-usage=2. The numerical values still work for historical scripts, etc, but this is more user friendly. Change-Id: I445ecd9638f801f5924a71eabf449bee293cdd34

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.
