| | | | | | | | | | | | | This change modifies the FFmpeg demuxer to recognize text streams embedded in the source media (Webm). Text decoder and text renderer filters have been added to the pipeline, to process the text frames as they are pulled downstream.

* Make VideoDecoderConfig copyable.xhwang@chromium.org2013-03-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | I guess the reasons we didn't make VideoDecoderConfig copyable is: 1) VideoDecoderConfig contains extra data, which needs deep copy. 2) We don't have a lot of use cases that needs to copy VideoDecoderConfig. If we do, we can use CopyFrom(). For (1), the extra data is typically small (< 100 bytes). Copying extra data should not have any performance impact. For (2), we do have legitimate cases where we need to copy VideoDecoderConfig implicitly: - Put VideoDecoderConfig in STL container, e.g. in SourceBufferStream. - Bind VideoDecoderCongfig in a callback, e.g. in DecryptingVideoDecoder. This CL uses std::vector<uint8> for the extra data and solves the deep copy issue. Then it makes VideoDecoderConfig copyable and makes several use cases of VideoDecoderConfig simpler.

* Roll FFMpeg for M26. Fix ffmpeg float audio decoding.dalecurtis@google.com2013-01-041-2/+3
| | | | | | | | | | | | | | | | | | | | | | | FFmpeg now outputs float for some audio decoders. Unfortunately our pipeline doesn't support float between the FFmpegAudioDecoder and AudioRenderer at present. As such, we need to convert the data into an integer format first. As a byproduct of this, AMR support for ChromeOS is finally fixed and adding support for PCM float is trivial. In summary this patch adds: - A SampleFormat property to AudioDecoderConfig. - AVSampleFormat <-> SampleFormat converters in FFmpegCommon. - Fixes ChromeOS AMR playback. - Finally plumbs pcm_f32le support (enabled in FFmpeg long ago). - Add decoder support for float planar and float interleaved playback. BUG=109085, 158187, 167069 TEST=unittests, layout tests, and demos all pass under tooling without issue.

* Switch to AVIO instead of a custom FFmpeg URLProtocol handler.dalecurtis@chromium.org2012-11-011-29/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FFmpegGlue is a filthy den of sin: - Singleton. - Unchecked initialization. - Mixed signed, unsigned usage. - Requires custom FFmpeg patches. - Hacks IO through http://0xDEADBEEF Switching to AVIO will absolve FFmpegGlue of its sins and has the added bonus of allowing us to tweak the buffer sizes used for read requests over the wire. AVIO works through a special AVIOContext created through avio_alloc_context() which is attached to the AVFormatContext used for demuxing. The AVIO context is initialized with read and seek methods identical to the existing URLProtocol structures. During avformat_open_input() we tell FFmpeg to use our AVIO context by passing NULL in for the filename parameter. FFmpeg will now redirect all reads and seeks through our AVIO context. The new FFmpegGlue also handles all destruction cases which can occur after an OpenContext(), allowing us to unify the slightly disparate shutdown paths used by FFmpegDemuxer and AudioFileReader. BUG=118986, 146529 TEST=unit tests under tooling. layout tests. manual playback pass.
