javascript - Dynamically created HTML5 audio is not playable in some browsers? -


i creating audio element in javascript , appending document. controlling through javascript well. works fine in firefox, chrome, , opera not on ie , safari. in 2 browsers, readystate of audio element never changes 0 nor associated events fire. here basic program:

var init = function() {     var audioelement = createaudioelement();             audioelement.addeventlistener('canplay', function() {         audioelement.play();         trace(audioelement.readystate);     }, false);     document.body.appendchild(audioelement);     //audioelement.play();   }  var createaudioelement = function() {     var m4a = 'song.m4a';     var ogg = 'song.ogg';      var m4asrc = document.createelement('source');         m4asrc.setattribute('src', m4a);         m4asrc.setattribute('type', 'audio/mp4');     var oggsrc = document.createelement('source');         oggsrc.setattribute('src', ogg);         oggsrc.setattribute('type', 'audio/ogg');     var audioele = document.createelement('audio');         audioele.setattribute('preload', 'preload');         audioele.appendchild(m4asrc);         audioele.appendchild(oggsrc);      return audioele; }

i know bit late, still; managed play audio on browsers (except ie < 9) without appending dom. can create audios this:

var audios = {}; audios['audioidorname'] = new audio('pathtoyouraudio');   // create audio element audios['audioidorname'].load();                           // force load audios['audioidorname'].addeventlistener('canplaythrough', audioloaded, false); // add event when audio loaded

then create audioloaded() function checks when audios loaded (if instance added more 1 in loop or 1 after another. 

var audiosloaded = 0 function audioloaded(){      audiosloaded++;     console.log("loaded "+this.src);     // here can check if number of audios loaded and/or remove eventlistener canplaythrough     audios['audioidorname'].removeeventlistener('canplaythrough', audioloaded, false);        }

then manipulate audios these functions: 

audios['youraudioidorname'].pause(); audios['youraudioidorname'].currenttime = 0; // pause() , currenttime = 0 imitate stop() behaviour doesn't exist ... audios['youraudioidorname'].play();

this worked me.

you can try appending audio element existing element if insist on appending dom. see more details here.

unfortunately there still many other issues html5 audio considering cross-browser usage. codecs 1 thing; using ogg+mp3 necessary. flash fallback not-so-neat solution used libraries/apis such soundmanager , howler.js. there soundjs may best thing try. see question well.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
