Trying to stream to android devices I am having to know HLS is not such a robust streaming option on Android devices. Is there a way to determine if the browser supports MPEG-DASH and if not provide an alternative HLS implementation through javascript? Thanks.
On Android >= 4.0 you can make use of the MSE for a MPEG-DASH playout (if you are using chrome). There are some HTML5/JS based DASH player solutions available, like dash.js or bitdash, which will also work on Android. I know that bitdash can even switch to a Flash fallback (if Flash is installed on the device) to support DASH on older Android versions.
You can check if your browser/OS/device combination supports DASH by using scripts like Radiant MediaLyzer.
On Android > 4.1 ExoPlayer, which is a native App for adaptive streaming including MPEG-DASH playout, can be a good choice as well.
