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

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

2011-03-21ARMv6 optimized fdct4x4Tero Rintaluoma

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.

2011-03-11Move build_intra_predictors_mby to RTCD frameworkJohn Koleszar
The vp8_build_intra_predictors_mby and vp8_build_intra_predictors_mby_s functions had global function pointers rather than using the RTCD framework. This can show up as a potential data race with tools such as helgrind. See https://bugzilla.mozilla.org/show_bug.cgi?id=640935 for an example. Change-Id: I29c407f828ac2bddfc039f852f138de5de888534

2011-03-111 Pass CQ and VBR bug fixesPaul Wilkins
Issue 291 highlighted the fact that CQ mode was not working as expected in 1 pass mode, This commit fixes that specific problem but in so doing I also uncovered an overflow issue in the VBR code for 1 pass and some data values not being correctly initialized. For some clips (particularly short clips), the resulting improvement is dramatic. Change-Id: Ieefd6c6e4776eb8f1b0550dbfdfb72f86b33c960
