Android MediaCodec use in Firefox for Android21 Oct 2014
James 'snorp' Willcox has landed support for hardware decoding via the public MediaCodec Java class in Nightly for Android for devices running Android 4.1+ (Jellybean). This is replacing OMXCodec & the Stagefright library which was introduced as a replacement for OpenCore for media decoding. This relatively new public Java class is used for decoding H.264/AAC in MP4 for playback in the browser with the benefit of allowing for direct access to the media codecs on the device through a "raw" interface.
This should correct a number of playback issues which have been reported to us regarding problems on Android 4.1+ devices.
