VideoJS currentTime() always returning 0

I'm using videoJs to load a video into an admin
platform built in react. I set up the player here :
else if (contentSource == 'arclight'){
var options = {
height:'216',
sources :[{
//src: this.state.video.url,
// type: 'video/mp4'
}]
}
var player = videojs('player',options,function onPlayerReady() {
videojs.log('Your player is ready!');
})
this.setState({
player:player,content: contentSource
});
}
My video is displayed in this tag :
<video id="player" class="player"
className={`video-js vjs-default-skin vjs-big-play-centered
${styles.vjs}`}
controls preload= "auto" data-
setup='{"example_option":true}'>
<source src={this.state.video.url} type= "video/mp4" />
<p className="vjs-no-js">
To view this video please enable JavaScript, and consider
upgrading to a web browser that
<a href= "http://videojs.com/html5-video-support"
target="_blank"> supports HTML5 video </a>
</p>
</video>
and lastly i'm trying to get the current time of the video that is playing in this method
handleCurrentButton(inputId, event){
event.preventDefault();
var timeMark =0;
if(this.state.content == 'vimeo'){
this.state.player.getCurrentTime().then(function(seconds){console.log(seconds)
timeMark=seconds;
VideosActions.updateVideoAttribute(inputId, timeMark);
}).catch(function(error){
});
}
else if(this.state.content == 'youtube') {
timeMark = Math.round(this.state.player.getCurrentTime());
VideosActions.updateVideoAttribute(inputId, timeMark);
}
else {
// timeMark = this.state.player.currentTime();
console.log(this.state.player.currentTime())
VideosActions.updateVideoAttribute(inputId, timeMark);
}
}
the problem is that the player.currentTime() call is always returning 0. The other two getCurrentTime's for Vimeo and Youtube work fine. what is the reason behind this? I tried to give enough context around this problem so that you would be able to figure it out.
Thanks for your help in advance!

The problem is getCurrentTime() returns a promise so you need to access the value of the time when the promise is resolved as a callback to the Promise's .then() function.
else {
this.state.player.currentTime().then(function(seconds){
console.log(seconds)
timeMark=seconds;
VideosActions.updateVideoAttribute(inputId, timeMark);
});
}

Worth making sure your server returning 206 response on the video HTTP request, otherwise players dont handle seek well.

How to randomize in pairs?

I'm trying to randomize some videos that are both .webm and .mp4.
I have a two of each video for instance vid1.webm and vid1.mp4
I'd like to have the videos randomize and pull both at the same time into the video tag.
safari doesn't support .webm so that's why i would like to have .mp4 as a backup and need both to randomize into the browser on click.
I am loading them from an array and also can't figure out how the folder structure should be listed out, I would really like to keep them in an array as I am loading in several hundred
var randomImage = new Array();
randomVideo[0] = "videos/1.webm/ or mp4"; //not sure how to do the file structure
randomVideo[1] = "videos/2.webm/ or mp4"; //
randomVideo[2] = "videos/3.webm/ or mp4"; //
//trying to figure out this part
$(function() {
$('a.click').click(function(e) {
e.preventDefault();
var number = Math.floor(Math.random()*randomVideo.length);
$(this).html('<source src="'+randomVideo[number]+'" />');
});
});
$(function() {
$('a.click').click(function(e) {
e.preventDefault();
var number = Math.floor(Math.random()*randomVideo.length);
$(this).html('<source src="'+randomVideo[number]+'" type="video/mp4" /> )
}
})
html
<a href="#" class="click">
<section>
<video controls autoplay>
<script>
randomVideo()
</script>
</video>
</section>
</a>
If anyone can help me figure this out it would be greatly appreciated!
Can't figure it out, still learning.

You have multiple issues. Firstly your array name doesn't match (randomImage and randomVideo). Not sure why you are hooking the click event twice. One approach is to store the common parts of the path in the array and then concatenate the file ending. Also, I have no idea what you were trying to do with the img tag...
Anyway, the code below should help you, if I have understood what you are trying to do correctly.
var randomVideo = new Array();
// define your common video paths here
randomVideo[0] = "videos/1";
randomVideo[1] = "videos/2";
randomVideo[2] = "videos/3";
function randomiseVideos() {
var number = Math.floor(Math.random() * randomVideo.length);
$('#myvid').empty(); // clean up from last time
// now add 2 sources (will fall back appropriately depending on client support)
$('#myvid').append('<source src="' + randomVideo[number] + '.webm" type="video/webm">');
$('#myvid').append('<source src="' + randomVideo[number] + '.mp4" type="video/mp4">');
}
$(function () {
// Randomise on page load
randomiseVideos();
// handle click on test link
$('a.click').click(function (e) {
e.preventDefault();
randomiseVideos();
});
});
HTML:
Test Link
<section>
<video id="myvid" width="320" height="240" controls autoplay></video>
</section>
JS fiddle demo

The video element supports multiple sources https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_HTML5_audio_and_video
A very simple solution would be to store a list of video objects in your array:
var videos = [
[{type:'mpg', 'src':'blah.mpg'}, {type:'webm', 'src':'blah.webm'}],
[{type:'mpg', 'src':'blah2.mpg'}, {type:'webm', 'src':'blah2.webm'}],
];
...
var video = videos[randomIndex];
And use that to output sources like:
<video controls>
<source src="blah.mpg" type="video/ogg">
<source src="blah.webm" type="video/mp4">
Your browser does not support the <code>video</code> element.

wami-recorder - Wami.startRecording is not a function

I am trying to implement Wami-Recorder as described here on stackoverflow with basically the same setup as in the accepted answer ie swfobject.js, recorder.js, and gui.js included in the head tag, the html controls contained in the divs:
<div id="recorder">
<button id="record">Record</button>
<button id="play">Play</button>
</div>
<div id="flash"></div>
and the JavaScript is just sitting at the bottom of the page just before the html end tag:
<script>
Wami.setup({
id: 'flash' // where to put the flash object
});
// initialize some global vars
var recording = '';
var recordingUrl = '';
var playBackUrl = '';
// get button elements
var record = $('#record');
var play = $('#play');
// define functions
function startRecording() {
recording = 'temp.wav';
recordingUrl = 'http://localhost/temp/wami/test/save_file.php?filename=' + recording;
Wami.startRecording(recordingUrl);
// update button attributes
record.html('Stop').unbind().click(function() {
stopRecording();
});
}
function stopRecording() {
Wami.stopRecording();
// get the recording for playback
playBackUrl = 'http://localhost/temp/wami/test/' + recording;
// update button attributes
record.html('Record').unbind().click(function() {
startRecording();
});
}
function startPlaying() {
Wami.startPlaying(playBackUrl);
// update button attributes
play.html('Stop').unbind().click(function() {
stopPlaying();
});
}
function stopPlaying() {
Wami.stopPlaying();
// update button attributes
play.html('Play').unbind().click(function() {
startPlaying();
});
}
// add initial click functions
record.click(function() {
startRecording();
});
play.click(function() {
startPlaying();
});
</script>
</body>
Now, I've never actually seen a working demo of Wami-Recorder, but I'm assuming there should actually be something in the flash container when it loads...? I get no error, and I can right click the area where the flash embed should be and the context menu confirms that there's a flash object loaded, and Firebug shows the DOM has been modified to:
<div id="recorder">
<button id="record">Record</button>
<button id="play">Play</button>
</div>
<div id="flash">
<div id="widb06765e52be" style="position: absolute;">
<object id="wid36dd0ea1ccc" width="214" height="137" type="application/x-shockwave-flash" data="Wami.swf" style="visibility: visible;">
<param name="allowScriptAccess" value="always">
<param name="wmode" value="transparent">
<param name="flashvars" value="visible=false&loadedCallback=Wami._callbacks['wid9ebef515c0b']&console=true">
</object>
</div>
</div>
as well as that the Wami.swf file was fetched via GET with 200 status.
Still, when I click the Record button, I get TypeError: Wami.startRecording is not a function. I'm assuming it's some sort of context issue, in that Wami is not a global for use inside a function for some reason. If so, can anyone explain why? If this is not the case, what have I overlooked?
Edit:
At one point I had tried to implement a more object-oriented way of doing things with:
var Audio = {
setup: function() {
Wami.setup("wami");
}
record: function() {
Audio.status("Recording...");
Wami.startRecording("https://wami-recorder.appspot.com/audio");
}
play: function() {
Wami.startPlaying("https://wami-recorder.appspot.com/audio");
}
stop: function() {
Audio.status("");
Wami.stopRecording();
Wami.stopPlaying();
}
status: function(msg) {
$('#status').html(msg);
}
};
And I would fire the functions from within the document.ready() method depending upon other conditions. The original implementation throws the exact same error, and I stripped it all out to try this more direct approach... to no avail.

You're on the right track! This is a lot of writing, but I hope it helps :-D
On the default implementation using the sample code from the Google repos, you do see the Flash GUI because it's initialized, but in this example, it does not and relies on the HTML buttons. The Flash is still on the page right below the buttons but white one white.
Your error
Using your code and files, the only way I was able to duplicate your error was to access the file via the file system:
file:///c:/xampp/htdocs/wami/index.html
Accessing the same content through a web server:
http://localhost/wami/index.html
works great.
So my assumption is that you don't have a web server to test on and are using the file system instead. I included links to XAMPP and basic setup instructions below, as well as the working code sample.
My setup:
I'm using XAMPP so the browser URL is set to http://localhost/wami/index.html.
You can download XAMPP here.
On Windows, it will install in C:\xampp by default.
Place all your files in C:\xampp\htdocs\wami and you should be all set.
Start APACHE in the XAMPP console
Open a browser and navigate to http://localhost/wami/index.html
I placed all files in that folder (all WAMI files including save_file.php). Once ran, and the first WAV file was created, I elevated the permissions on it for testing (right-click, add FULL CONTROL permission for All Users (I'm on Windows 7).
Full working code sample (same as yours but has the entire code chunk for reference. I removed https:// from the JavaScript call since mixing http and https can cause security popups and broken JavaScript)
I used the PHP file as-is with this code:
<?php
// get the filename
parse_str($_SERVER['QUERY_STRING'], $params);
$file = isset($params['filename']) ? $params['filename'] : 'temp.wav';
// save the recorded audio to that file
$content = file_get_contents('php://input');
$fh = fopen($file, 'w') or die("can't open file");
fwrite($fh, $content);
fclose($fh);
?>
And the HTML file:
<!-- index.html -->
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script src="//ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js"></script>
<script src="recorder.js"></script>
</head>
<body>
<div id="recorder">
<button id="record">Record</button>
<button id="play">Play</button>
</div>
<div id="flash"></div>
<script type="text/javascript">
// initialize Wami
Wami.setup({
id: 'flash' // where to put the flash object
});
// initialize some global vars
var recording = '';
var recordingUrl = '';
var playBackUrl = '';
// get button elements
var record = $('#record');
var play = $('#play');
// define functions
function startRecording() {
recording = 'temp.wav';
recordingUrl = 'save_file.php?filename=' + recording;
Wami.startRecording(recordingUrl);
// update button attributes
record.html('Stop').unbind().click(function() {
stopRecording();
});
}
function stopRecording() {
Wami.stopRecording();
// get the recording for playback
playBackUrl = recording;
// update button attributes
record.html('Record').unbind().click(function() {
startRecording();
});
}
function startPlaying() {
Wami.startPlaying(playBackUrl);
// update button attributes
play.html('Stop').unbind().click(function() {
stopPlaying();
});
}
function stopPlaying() {
Wami.stopPlaying();
// update button attributes
play.html('Play').unbind().click(function() {
startPlaying();
});
}
// add initial click functions
record.click(function() {
startRecording();
});
play.click(function() {
startPlaying();
});
</script>
</body>
</html>

The flash object was being embedded in the page, but none of the event listeners were working. I have since switched to jRecorder link, and with a few modifications to the code, have it working with no issues.

Cortado Ogg-player in MediaElement.js - almost working

I made a few changes to the MEjs demo player, to enable playback of OGG in IE/Safari browsers, using the Cortado Java applet.
I have play/pause working, and although getPlayPosition() isn't getting the current position in milliseconds as described in the documentation, applet.currentTime and applet.duration work well for this purpose.
I thought it would be simple to hook these up to the current position indicators on the mejs player, but I'm running into a problem. setCurrentTime on the object is causing DOM Exception: InVALID_STATE_ERR (11) in IE, and a similar error happens in Safari. Apparently the object I'm trying to set no longer exists?
The code below will play and pause, and even give the seconds/total in the console (F12 tools MUST be enabled in IE.) Is there a good way to connect this to the play bar?

This is using MeJS 2.10.3.

[EDIT]
After inspecting the MediaElement.js code, it seems that mejs.players is not an array, but an object, and in order to access the first player, you would have to look into mejs.players['mep_0'], since mejs.players[0] would be undefined.
My guess would be that jQuery fails to create an interactive <applet> element, since, from my experience, jQuery (which heavily relies on document.createDocumentFragment) sometimes fails to attach/trigger events on dynamically created/cloned DOM nodes, especially in IE, which could be the cause for this DOM error that you're seeing, because your <applet> object probably failed to initialize.
To try and fix this problem, I'd suggest to use the native document.createElement and document.appendChild methods instead of the jQuery.append.
if (jQuery(this.$node).find('applet').length==0) {
var createElem = function(name, attributes) {
var el = document.createElement(name);
attributes = attributes || {};
for (var a in attributes) {
el.setAttribute(a, attributes[a]);
}
return el;
};
var applet = createElem('applet',{
code:'com.fluendo.player.Cortado.class',
codebase: 'http://theora.org/',
archive: 'cortado.jar',
width: 100,
height: 100
});
applet.appendChild(createElem('param', {name:'url', value:d.src}));
applet.appendChild(createElem('param', {name:'seekable', value: 'true'}));
applet.appendChild(createElem('param', {name:'autoPlay', value: 'false'}));
this.$node.get(0).appendChild(applet);
}

New to Javascript, need help with HTML5 audio "playlist"

im trying to create a sort of playlist feature that will work on the iPhone using a combination of HTML5 and javascript. I'm very new to the platform and I was hoping maybe someone here could help me identify the problem with my code. The first song properly autoplays, but when it ends the next one does not load and play. The javascript code for my site is provided below, thanks in advance. (my apologies if this code is terribly messed up, i assembled this from what iv learned and what i could find different places online)
<script type="text/javascript">
var songname="Bottoms Up";
var counter=1;
var totalsongs=3;
while (counter<=totalsongs-1) {
document.write(<h2>songname</h2>);
switch (counter) {
case 1:
var nextSong="audio/Hey.mp3";
var audioPlayer=document.getElementById('audioPlayer');
audioPlayer.onend = function() {
audioPlayer.src = nextSong;
songname="Hey";
counter=(counter+1);
if(counter>totalsongs-1) {
counter=1;
} //if close
} //onend function close
case 2:
var nextSong="audio/I Like It.mp3";
var audioPlayer=document.getElementById('audioPlayer');
audioPlayer.onend = function() {
audioPlayer.src = nextSong;
songname="I Like It";
counter=(counter+1);
if(counter>totalsongs-1) {
counter=1;
} //if close
} //onend function close
} //switch close
} //while close
</script>
<center><audio src="audio/Bottoms Up.mp3" autoplay controls /></center>

A few things:
Give the audio element an id:
<audio src="audio/Bottoms Up.mp3" autoplay controls id="audioPlayer" /></center>
Use arrays instead of many variables:
var songs=({{"title": "First title","filename":"firstfile.mp3"},
{"title": "Second title","filename":"secondfile.mp3"}});
Listen for the event ended like this:
document.getElementById("audioPlayer").addEventListener("ended", nextSong, false);
And put the script in the <head> element.

var audioPlayer=document.getElementById('audioPlayer');
… will error, since the element doesn't have an id.
