This change has to be made because FMP4 is meant to take over GStreamer for MP4 file format. This way, FMP4 will be instantiated by default over GStreamer if both tools work (on a certain Linux platform).
Report that we can play MP3 inside MP4 on Windows Vista and later in
HTMLMediaElement.canPlayType. Chrome and IE on Windows match this behaviour.
Add a test file with MP3 contained inside MP4. Note the B2G emulator can't play
this file, so I added a codecs parameter to the file's mime type so that
decoder backends have to opt-in to testing with it.
Enable playback of MP3 inside MP4 in WMFReader.
Change from reporting the IMFSourceReader's duration inside WMFReader, to
instead report the IMFSourceReader's duration as the media "end time". This is
needed because the MP3-contained-in-MP4 file's first sample output by the
IMFSourceReader has a non-zero timestamp, and the MediaDecoderStateMachine
assumes that the media samples will be in the range
[$firstSampleStartTime, $firstSampleStartTime+$reportedDuration]. But that's
not the case here, the IMFSourceReader seems to output samples in the range
[0,$reportedDuration]. This assumption mismatch means on the
MP3-contained-in-MP4 file we end up trying to seek after what the
IMFSourceReader assumes is the end of the file, which fails and causes
test failures.
Support the Opus audio codec in the WebM (Matroska) container.
This is part of the "WebM 2" proposed spec, which also includes
the new VP9 video codec. Alas we weren't able to get concensus
to change the doctype of filename extension to mark the revision
allowing the new codecs.
All codec-specific code is hidden within DecoderTraits and available
from generic interfaces. This patch removes the codec-specific
functions from DecoderTraits' public interface.
This change moves the policy of supported media types in the element
nsHTMLMediaElement to the DecoderTraits class. The codec-specific code
has been removed from the media element.
The class DecoderTraits knows about all supported decoders. Adding
an interface to create decoder instances simplifies all users of this
functionality. nsHtmlMediaElement has been updated to use the new
function.
