2011-03-21Merge "Fix multithreaded encoding for 1 MB wide frame"Yunqing Wang
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
Optimized fdct4x4 (8x4) for ARMv6 instruction set. - No interlocks in Cortex-A8 pipeline - One interlock cycle in ARM11 pipeline - About 2.16 times faster than current C-code compiled with -O3 Change-Id: I60484ecd144365da45bb68a960d30196b59952b8
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.

Fixes implicit declaration warning for 'mach_task_self'. This change is an update to Change I9991dedd1ccfddc092eca86705ecbc3b764b799d, which fixed this issue for the decoder but not the encoder. Change-Id: I9df033e81f9520c4f975b7a7cf6c643d12e87c96

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

2011-03-11Clean up of vp8_init_config()Paul Wilkins
Clean up vp8_init_config() a bit and remove null pointer case, as this code can't be called any more and is not an adequate trap anyway, as a null pointer would cause exceptions before hitting the test. Change-Id: I937c00167cc039b3aa3f645f29c319d58ae8d3ee
2011-03-11Merge "1 Pass CQ and VBR bug fixes"John Koleszar
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

2011-03-11Encoder loopfilter running in its own threadAttila Nagy
In multithreaded mode the loopfilter is running in its own thread (filter level calculation and frame filtering). Filtering is mostly done in parallel with the bitstream packing. Before starting the packing the loopfilter level has to be calculated. Also any needed reference frame copying is done in the filter thread. Currently the encoder will create n+1 threads, where n > 1 is the number of threads specified by application and 1 is the extra filter thread. With n = 1 the encoder runs in single thread mode. There will never be more than n threads running concurrently. Change-Id: I4fb29b559a40275d6d3babb8727245c40fba931b

2011-03-10Removed firstpass motion mapAdrian Grange
The firstpass motion map consists of an 8-bit flag for each MB indicating how strongly the firstpass code believes it should be filtered during the second pass ARNR filtering. For long or large format material the motion map can become extremely large and hamper the operation of the encoding process. This change removes the motion map altogether, leaving the second pass to rely on the magnitude of the motion compensated error to determine the filter weight to use for the MB during ARNR filtering. Tests on the derf set indicate that the effect of this change is neutral, with some small wins and losses. The motion map has therefore been removed based on a cost/benefit evaluation.

2011-03-10Fix incorrect macroblock counts in twopass rate controlJames Berry
The previous calculation of macroblock count (w*h)/256 is not correct when the width/height are not multiples of 16. Use the precalculated macroblock count from cpi->common instead. This manifested itself as a divide by zero when the number of pixels was less than 256. num_mbs updated in estimate_max_q, estimate_q, estimate_kf_group_q, and estimate_cq Change-Id: I92ff98587864c801b1ee5485cfead964673a9973
