是否可以使用其 javascript API 为 azure 媒体播放器选择质量？

Question

Looking to implement azure media player for a project. But we need to use our existing custom video controls. Is it possible to control the quality selector by javascript? Have not been able to find anything concerning this in the documentation..

Does anyone have experience with this?

Any help would be appreciated!

Could also be worth noting that this is a react.js project.

Thanks,

You can specify the heuristic profile (HighQuality, Hybrid, LowLatency, QuickStart):

http://amp.azure.net/libs/amp/latest/docs/index.html#amp.player.heuristicprofile

http://amp.azure.net/libs/amp/latest/docs/#amp.videostream.selecttrackbyindex

try something like this:

myPlayer.addEventListener(amp.eventName.loadedmetadata,
    function() {

        var stream = myPlayer.currentVideoStreamList().streams ?
            myPlayer.currentVideoStreamList().streams[0] :
            undefined;

        if (stream) {
            stream.selectTrackByIndex(0);
        }

    });



myPlayer.src([{
    src: "[srcuri]",
    type: "application/vnd.ms-sstr+xml"
}]);
