2011-03-21Merge "Increase static linkage, remove unused functions"John Koleszar
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
2011-03-16apple: include proper mach primativesJohn Koleszar
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

Adds vp8_sub_pixel_variance16x16_armv6 function to encoder. Integrates ARMv6 optimized bilinear interpolations from vp8/common/arm/armv6 and adds new assembly file for variance16x16 calculation. - vp8_filter_block2d_bil_first_pass_armv6 (integrated) - vp8_filter_block2d_bil_second_pass_armv6 (integrated) - vp8_variance16x16_armv6 (new) - bilinearfilter_arm.h (new) Change-Id: I18a8331ce7d031ceedd6cd415ecacb0c8f3392db
2011-02-08clean up bilinear filterJohann
make reference version of bilinear_filters short. use reference versions of bilinear_filters and sub_pel_filters when possible. recognize that Width was being passed into filter_block2d_bil_first_pass multiple times. ARM version had already fixed this. propegate to C. change references to src_pixels_per_line to src_pitch and standardize on src/dst (instead of input/output). recognize that first_pass is only run in the verticle and second_pass only horizontal. ARM version had already fixed this. propegate to C Change-Id: I292d376d239a9a7ca37ec2bf03cc0720606983e2

2011-01-28Adds "armvX-none-rvct" targetsTero Rintaluoma
Adds following targets to configure script to support RVCT compilation without operating system support (for Profiler or bare metal images). - armv5te-none-rvct - armv6-none-rvct - armv7-none-rvct To strip OS specific parts from the code "os_support"-config was added to script and CONFIG_OS_SUPPORT flag is used in the code to exclude OS specific parts such as OS specific includes and function calls for timers and threads etc. This was done to enable RVCT compilation for profiling purposes or running the image on bare metal target with Lauterbach. Removed separate AREA directives for READONLY data in armv6 and neon assembly files to fix the RVCT compilation. Otherwise "ldr <reg>, =label" syntax would have been needed to prevent linker errors. This syntax is not supported by older gnu assemblers. Change-Id: I14f4c68529e8c27397502fbc3010a54e505ddb43

2011-01-19Merge "Implement error tracking in the decoder"John Koleszar
2011-01-19Implement error tracking in the decoderHenrik Lundin
A new vpx_codec_control called VP8D_GET_FRAME_CORRUPTED. The output from the function is non-zero if the last decoded frame contains corruption due to packet losses. The decoder is also modified to accept encoded frames of zero length. A zero length frame indicates to the decoder that one or more frames have been completely lost. This will mark the last decoded reference buffer as corrupted. The data pointer can be NULL if the length is zero. Change-Id: Ic5902c785a281c6e05329deea958554b7a6c75ce

2011-01-07CQ ModePaul Wilkins
The merge includes hooks to for CQ mode and other code changes merged from the test branch. CQ mode attempts to maintain a more stable quantizer within a clip whilst also trying to adhere to a guidline maximum bitrate. The existing target data rate parameter is used to specify the guideline maximum bitrate. A new parameter allows the user to specify a target CQ level. For normal (non kf/gf/arf) frames, the quantizer will not drop BELOW the user specified value (0-63). However, in some cases the encoder may choose to impose a target CQ that is above that specified by the user, if it estimates that consistent use of the target value is not compatible with guideline maximum bitrate.

2010-12-29Always update last_frame_typeYunqing Wang
Scott pointed out that last_frame_type only gets updated while loopfilter exists. Since last_frame_type is also needed in motion search now, it needs to be updated every frame. Change-Id: I9203532fd67361588d4024628d9ddb8e391ad912
2010-12-17Add psnr/ssim tuning optionJohn Koleszar
Add a new encoder control, VP8E_SET_TUNING, to allow the application to inform the encoder that the material will benefit from certain tuning. Expose this control as the --tune option to vpxenc. The args helper is expanded to support enumerated arguments by name or value. Two tunings are provided by this patch, PSNR (default) and SSIM. Activity masking is made dependent on setting --tune=ssim, as the current implementation hurts speed (10%) and PSNR (2.7% avg, 10% peak) too much for it to be a default yet.

2010-12-14shrink TOKENEXTRA and vp8_extra_bit_structJohann
Per John's previous change, shrink TOKENEXTRA from 20 to 8 bytes original: b7b1e6fb reverted: 41f4458a Also drop unused field from vp8_extra_bit_struct Update ARM ASM to deal with this change. In particular, Extra is signed and needs to be sign-extended when loaded. Change-Id: Ibd0ddc058432bc7bb09222d6ce4ef77e93a30b41

2010-11-10postproc : Re-work posproc calling to allow more flags.Fritz Koenig

2010-10-27Eliminate more warnings.Timothy B. Terriberry
This eliminates a large set of warnings exposed by the Mozilla build system (Use of C++ comments in ISO C90 source, commas at the end of enum lists, a couple incomplete initializers, and signed/unsigned comparisons). It also eliminates many (but not all) of the warnings expose by newer GCC versions and _FORTIFY_SOURCE (e.g., calling fread and fwrite without checking the return values). There are a few spurious warnings left on my system: ../vp8/encoder/encodemb.c:274:9: warning: 'sz' may be used uninitialized in this function gcc seems to be unable to figure out that the value shortcut doesn't change between the two if blocks that test it here. ../vp8/encoder/onyx_if.c:5314:5: warning: comparison of unsigned expression >= 0 is always true ../vp8/encoder/onyx_if.c:5319:5: warning: comparison of unsigned expression >= 0 is always true This is true, so far as it goes, but it's comparing against an enum, and the C standard does not mandate that enums be unsigned, so the checks can't be removed.

2010-10-27postproc: Tweaks to line drawing and blending.Fritz Koenig
Turned down the blending level to make colored blocks obscure the video less. Not blending the entire block to give distinction to macro block edges. Added configuration so that macro block blending function can be optimized. Change to constrain line as to when dx and dy are computed. Now draw two lines to form an arrow.

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
2010-10-26arm: 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. Change-Id: I4612fdbc606fbebba4971a690fb743ad184ff15f
2010-10-26arm: remove duplicate functionsJohn Koleszar
