* Consolidate AudioRendererAlgorithm classes into one classvrk@google.com2011-12-191-16/+1
| | | | | | | | | | | | | | There's no reason to have 2 derived classes of AudioRendererAlgorithmBase. This CL deletes the derived classes and pushes the behavior into the base class. It shouldn't change any existing logic; should be just pushing things around.

* Removing DataSource from Filter hierarchy and refactoring FilterHost into ↵acolwell@chromium.org2011-12-161-0/+7
| | | | | | | | | | | | | | DemuxerHost & DataSourceHost. Over the last year, several refactorings have caused DataSource to have almost nothing in common with the Filter interface. This change removes it from the Filter class hierarchy and splits up the FilterHost interface so that DataSource, Demuxer, and Filter have their own host interfaces. Splitting FilterHost improves encapsulation and makes it easier to reason about which host methods are required by different parts of the code.

* <video> decode in hardware! fischman@chromium.org2011-12-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | This uses the GpuVideoDecodeAccelerator machinery (already written to enable ppapi to take advantage of OpenMAX HW where available) to decode <video> data. This increases idle CPU from 20% to 45% on one particularly large (internal) test video (red0.mp4), on an ARM crosbook. HW decode is done on a best-effort basis; if the GPU code doesn't know how to deal with a codec/profile we still fall back to ffmpeg for decode. Because the vast majority of chrome installs will be on HW with no video decode support (yet) we only attempt HW video decode on platforms we know have a shot at it.

* Replace AudioDecoderConfig with simple accessors on AudioDecoder.scherkus@chromium.org2011-09-161-1/+0
| | | | | | | | AudioDecoderConfig was being used as a struct for outputting format information to an AudioRenderer. This was confusing and in contrast to VideoDecoderConfig, which is is actually used as input to configure a video decoder!

* Reorganize YUV scalers (Continued)hclam@chromium.org2011-09-161-8/+10
| | | | | | | | | | | | | | | | | | | | After rewriting assembly code in YASM we can finally move all these different versions of files in the same folder, i.e. media/base/simd. After this change the main entry point will be: yuv_convert.cc and yuv_convert.h It then calls into the internal functions under media/base/simd. After this change I'll move all the color conversion files to media/csc.

There are couple advantages in this YASM version. 1. Performance improvement Using YASM we can push less to the stack, this results in ~5% improvement on 32-bits system. 2. MMX and SSE versions are separate SSE version use movntq while MMX version use movq. 3. 64-bits version works universally This means that 64-bits YASM code compile and run on 64-bits windows, mac and linux. While previously it only runs on linux 64. 4. Handling PIC much better PIC code runs and build on 32-bits and 64-bits system. This is better than before which only works on 32-bits mac. 5. Easier maintenance This code uses x86asm.inc for a bunch of nice macros. Having just one YASM verion is better than having inline VC assembly and don't have to worry inline assemly has different register names on mac and linux. I tested on linux 32-bits, linux 32-bits PIC and linux 64-bits that this code is at least as fast as before.
