* Rename media::AudioRendererImpl to media::ReferenceAudioRendererImpl.fischman@chromium.org2011-10-076-34/+32

* Fix hangs & crashes in teardown-during-Seek.fischman@chromium.org2011-10-074-14/+23
| | | | | | | | | | | | | | | | | | | | | | | | Hangs: - AudioRendererImpl: Don't hold lock_ in the call to Join() b/c OnStop wants to acquire the lock before exiting. - FFmpegDemuxerStream::Stop: signal EOS to waiting read callbacks (instead of silently dropping them on the floor) so decoders can exit instead of stalling (and causing renderers to stall). Crashes: - CompositeFilter::Stop: clear out the Seek callback when Stopping. - FFmpegVideoDecoder::ProduceVideoFrame: early-return if already stopped (racing with webkit repaints makes this necessary). Also fixed a bunch of mis-indentation where I saw it.

* Re-write the alsa polling scheduling to make it work with low buffer audio, ↵xians@chromium.org2011-10-052-24/+45
| | | | | | | | | | | | | | | | | | for example, 10ms for playout. Before this patch, the alsa scheme sets a frame_avail_wanted as half of the ALSA buffer size, then it checks if the available_frame buffer slot in ALSA is smaller than frame_avail_wanted, if it is, which means that ALSA has more buffer than we need, then it schedule the next time to be FrameToMills(frame_avail_wanted - available_frame). Otherwise, we invoke the next write immediately. But this scheduling scheme doesn't handle the following cases well: #1, It has a chance running into a dead lock that we always have less than half of the buffer filled, where it runs into a busy looping. This happens mostly when the buffer size is small. #2, We can write more data to ALSA than what it needs. This patch fixes the problems by initiating the next time for the moment when half of packet is played out. Then it checks with ALSA on how many frames are available, and do a re-scheduling: if the available frames are not enough for a packet, it schedules the next write for the moment when the buffer for a packet becomes available, if the next write happens in less than 10ms, then it will use 10ms in order to avoid back to back writing; if the existing frames are less than half packet, it make next write to be immediate.

* Adding delay estimation to input audio.xians@chromium.org2011-10-049-11/+38
| | | | | | | | | | | | | | On linux, snd_pcm_delay API will be used to get the delay value from ALSA; On mac, the AudioQueue implementation will just use the buffer size as delay value since we may not use this impl for recording; the low-latency AudioUnits implementation will use some AudioUnitGetProperty() API to get the accurate delay value from the driver; On windows, for the Wave implementation, based on the tests we do, it should be OK to use the buffer size as the delay value; for the to-be-implemented core audio implementation, we will see what is the appropriate way to get the delay there.

A bit of background on FooCallback vs. FooCB: when acolwell@ & I did the first conversions to the new world, everything was named FooCallback. I proposed using FooCB for the migrated ones as a way to both easily visually differentiate as well as save characters (!). Now that we have an additional "don't typedef Closures" guideline I like having FooCB for non-closure new-style callbacks, and FooClosure for new-style closures.

| | | | | | | | 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!

| | | | | | | | | | | | | | | | | | | | 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.
