android - HTML5 video buffers backwards -

-

i implemented buffer bar html5 videos. when watch them via browser, buffers fine, via android app works buffer bar jumping.

percentage goes example 0.10 -> 0.25 -> 0.20 -> 0.30 -> 0.35 -> 0.30 , on. looks twitching reason.

what cause problem?

i using shared hosting pulling out of vps server, same result , via phone's browser. chrome browser on phone or webview on app causes same result...

as mentioned, have no idea causes on browser works fine..but that's js:

var startbuffer = function(buffer,myvideo) {  var maxduration = myvideo.duration; var currentbuffer = myvideo.buffered.end(0); var percentage = 100 * currentbuffer / maxduration; $('.'+buffer).css('width', percentage+'%');  if(currentbuffer == maxduration){     cleartimeout() } else {     settimeout(function(){startbuffer(buffer,myvideo);}, 100); } console.log("maxduration:"+maxduration); console.log("buffer:"+currentbuffer); console.log("video:"+buffer); };

the buffer , myvideo values comes piece of code:

$('.play').on('click', function () {     var myvideo = $('#' + $(this).data('video-id')).get(0);      var buffer = $(this).data('buffer-id');      if (myvideo.paused) {         $('video').each(function () {           this.pause();         });       myvideo.play();        startbuffer(buffer,myvideo);     }     else {        myvideo.pause();      }  });

and thats android code webview:

    webview webview = (webview) getactivity().findviewbyid(r.id.webview);      websettings websettings = webview.getsettings();     webview.setscrollbarfadingenabled(false);     websettings.setjavascriptenabled(true);     webview.setwebviewclient(new webviewclient());     webview.loadurl("http://website.com");

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
