javascript - SoundManager on 100% HTML5 mode stuck on "stalled" -


in smart-tv app, i'm using soundcloud api, through cross domain request - $.getjson() etc.
app uses soundmanager2 api on 100% html5 mode (no flash) load tracks .stream_url retrieved soundcloud. problem begins when trying play loaded tracks. app loaded 10 tracks, of them won't play.
noticed log stating:

0040  sound0: play(): loading - attempting play... 0041  sound0: abort 0042  sound0: waiting 0043  sound0: loadstart 0044  sound0: stalled

where stays forever. issue happens same tracks, while other tracks streamable, , playable, showing log:

0078  sound2: durationchange (191190) 0079  sound2: loadedmetadata 0080  sound2: stalled 0081  sound2: suspend 0082  sound2: loadeddata 0083  sound2: canplay 0084  sound2: onload() 0085  sound2: playing ♫

the code used create sound object, , play it:

        soundobject = soundmanager.createsound({    //  load current track             url: "https://api.soundcloud.com/tracks/" + trackids[elements][index-1] + "/stream?client_id=f430822ab78177a5cfb94d572d9036a2",             volume: 100,             autoload:    true,              //autoplay:      true,             //stream:        true,             whileplaying:function(){currentposition=soundobject.position;barwhileplaying(elements, index, currentposition);},                                      onfinish:    function(){baronfinish(elements, index);},                                    onstop:      function(){baronstop(elements, index);},         });         soundobject.play();

(where whileplaying, onfinish, , onstop parameters call function changes css and/or classes of elements within html document.)

my questions:

  1. is there way know beforehand smsound object won't play?
  2. say can't know before loading it "loadstart" , "stall" forever, there way of knowing after loaded?
    i'm asking since of tracks load , play after long periods of time.

i can suggest work-around may help.

var mysound = soundmanager.createsound({..});   mysound.load();   settimeout(function() {     if (mysound.readystate == 1) {         // object stalled         } },5500);

this works since in html5, unlike flash, readystate property jumps '0'(uninitialized - not yet loaded) '3'(loaded) instantanously, skipping '1'(initialized - started loading), cause if sound started buffering it's playable in html5, hence readystate returns 3...
on html5, permanently (or long duration) stalled sounds have readystate = 1 long after load() attempt.

after - can replace/remove/skip errouneous track or whatever.

  • note - 5500 msec's should long enough, can play around , see best timeout platform.

hope you.
