With the all-new Kindle Fire and the Kindle Fire HD, there are several changes to the way media is handled in the browser. The biggest change is that Flash is no longer supported in the browser, due to significant changes to the version of Android used on the devices. Instead, our HTML5 support is improved, with support for both the HTML5 <video> and <audio> tags.
We currently support MP4 and WEBM video formats. If your<video> tag contains multiple formats we'll prefer MP4. The audio encoding in video streams must be at most stereo, the Kindle Fire family of devices doesn't support 5.1 audio. RTSP and HLS are supported by the Android player activity, for details on formats see http://developer.android.com/guide/appendix/media-formats.html.
We know that publishers want support from the browser for embedded video and that is something that we’re investigating.
Image support has also been improved. In addition to all the expected browser image formats, we now support SVG via both the HTML5<svg> tag and .svg resources in <img> tags.
There is no current support for any kind of background audio, meaning that audio playback is paused when a tab loses focus.
