Phaser Audio Support in Internet Explorer 11 - html

No matter what I try, I cannot get any audio files to play in Internet Explorer (11) when using Phaser. I have tried both mp3 and m4a (encoded using default settings in Audacity).
Also, I have tried loading all Audio examples on the Phaser site in Internet Explorer (http://examples.phaser.io/) and none of these seem to load either.
I can get ogg files to play fine in Chrome, Firefox and Opera, but that's about it.
I found another forum where a user mentioned that they used Audacity to convert to mp3 and had success:
http://www.html5gamedevs.com/topic/5682-audiofiles-wav-and-ogg-not-loaded-in-internet-explorer/
But I am not having any luck.
Any ideas? I can provide any more detail as necessary.
Thanks for your time and your help.

IE11 cannot play m4a files. Well, it's a little more complex than this - it can't play them unless you have iTunes (or similar codec installing software) installed. Therefore you can't count on it working reliably for everyone.
It can however play mp3s, but it depends entirely on how you have encoded them. Not all mp3s are created equal. I would suggest you 'borrow' some mp3s from an official IE Audio demo like this one to use for testing. If these work then the issue is the mp3s you've created. If they don't work either, the issue is somewhere in your code.
However, as you said the official examples don't work in IE11 for you, I wouldn't rule out it being something local to your PC either, as they do actually work fine. A driver / codec issue quite possibly.

.mp4 file not playing in chrome

I want to show a video on my website. I have created a .mp4 file and using the HTML5 video tag to add it to the html.
The problem is that it is not being displayed in chrome. I would also like to know how I can replay it again and again.
I too had the same issue. I changed the codec to H264-MPEG-4 AVC and the videos started working in HTML5/Chrome.
Option selected in converter: H264-MPEG-4 AVC, Codec visible in VLC player: H264-MPEG-4 AVC (part 10) (avc1)
Hope it helps...
After running into the same issue - here're some of my thoughts:
due to Chrome removing support for h264, on some machines, mp4 videos
encoded with it will either not work (throwing an Parser error when
viewing under Firebug/Network tab - consistent with issue submitted
here), or crash the browser, depending upon the encoding settings
it isn't consistent - it entirely depends upon the codecs installed
on the computer - while I didn't encounter this issue on my machine,
we did have one in the office where the issue occurred (and thus we
used this one for testing)
it might to do with Quicktime / divX settings (the machine in
question had an older version of Quicktime than my native one - we
didn't want to loose our testing pc though, so we didn't update it).
As it affects only Chrome (other browsers work fine with VideoForEverybody solution) the solution I've used is:
for every mp4 file, create a Theora encoded mp4 file (example.mp4 -> example_c.mp4)
apply following js:
if (window.chrome)
$("[type=video\\\/mp4]").each(function()
{
$(this).attr('src', $(this).attr('src').replace(".mp4", "_c.mp4"));
});
Unfortunately it's a bad Chrome hack, but hey, at least it works.

This also can help: chrome could play html5 mp4 video but html5test said chrome did not support mp4 video codec
Also check your version of crome here: html5test
(#Alston posted this as a comment, and it worked for me, and 9 others who also upvoted, so posting this as an answer to get more eyeballs on it:)
Simply re-encoding the video file with this FFMPEG command solves it:
ffmpeg -i input.mp4 -vcodec h264 output.mp4
This started out as an attempt to cast video from my pc to a tv (with subtitles) eventually using Chromecast. And I ended up in this "does not play mp4" situation. However I seemed to have proved that Chrome will play (exactly the same) mp4 as long as it isn't wrapped in html(5)
So here is what I have constructed. I have made a webpage under localhost and in there is a default.htm which contains:-
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<video controls >
<source src="sample.mp4" type="video/mp4">
<track kind="subtitles" src="sample.vtt" label="gcsubs" srclang="eng">
</video>
</body>
</html>
the video and subtitle files are stored in the same folder as default.htm
I have the very latest version of Chrome (just updated this morning)
When I type the appropriate localhost... into my Chrome browser a black square appears with a "GO" arrow and an elapsed time bar, a mute button and an icon which says "CC". If I hit the go arrow, nothing happens (it doesn't change to "pause", the elapsed time doesn't move, and the timer sticks at 0:00. There are no error messages - nothing!
(note that if I input localhost.. to IE11 the video plays!!!!
In Chrome if I enter the disc address of sample.mp4 (i.e. C:\webstore\sample.mp4 then Chrome will play the video fine?.
This last bit is probably a working solution for Chromecast except that I cannot see any subtitles. I really want a solution with working subtitles.
I just don't understand what is different in Chrome between the two methods of playing mp4
Encountering the same problem, I solved this by reconverting the file with default mp4 settings in iMovie.
I was actually running into some strange errors with mp4's a while ago. What fixed it for me was re-encoding the video using known supported codecs (H.264 & MP3).
I actually used the VLC player to do so and it worked fine afterward. I converted using the mentioned codecs H.264/MP3. That solved it for me.
Maybe the problem is not in the format but in the JavaScript implementation of the play/ pause methods. May I suggest visiting the following link where Google developer explains it in a good way?
Additionally, you could choose to use the newer webp format, which Chrome supports out of the box, but be careful with other browsers. Check the support for it before implementation. Here's a link that describes the mentioned format.
On that note: I've created a small script that easily converts all standard formats to webp. You can easily configure it to fit your needs. Here's the Github repo of the same projects.

Embedded webm video freezes in Chrome

I am making a system that I run on localhost, it embeds a video player and all works fine except for webm videos on Chrome. They freeze regularly and I can only get them running again by pressing play/pause and moving to the initial phases of the video.
I have been googling for this issue and trying to solve it for some time now without success, does anybody know how to solve this?
Is your same WebM file working ok on Firefox? I assume you are using HTML5 video.
I have compiled a short check list on how to troubleshoot HTML5 video playback issue here. Try to play the videojs webm sample to see if it works.
Given the description of your issue I guess it is either a non proper WebM file or a server side tuning issue (like with mime types).
If it is a file format issue you could try re-transcoding from a known good source (ie not the problematic WebM file) with firefogg.
You can also try to set the preload attribute of your HTML5 video tag to auto.

How to deal with poor HTML5 video performance in Chrome?

Over a year ago we added an video page on our site. At the time OGV wasn't very good, and there was no good WebM encoders available, so we decided to use HTML5 and h.264 for webkit browsers (Chrome, Safari, etc.) and then fallback to Flash for other browsers (using the same h.264 source file.)
This has been working great for a while. Recently (month or two maybe, so over multiple Chrome versions - currently Version 24.0.1312.52 m) we discovered Chrome really lagging on the playback. We thought it was a server issue, so we upgraded the server, and it is still behaving the same. I remembered reading that Google wanted to drop h.264 and move everyone to WebM, and thought this performance was part of that. We converted some videos to WebM and tested them with Chrome and they lag just as bad. Same video (WebM) streams beautifully in FireFox, and the MP4 streams great in FireFox via the Flash plug in.
I went to YouTube and turned on the HTML5 video support, and found the videos to lag in Chrome too (when running at HD) while they play fine in Flash mode. (Even when HTML5 is enabled, some videos still play via Flash.)
Tested on both Windows 8 and Mountain Lion.
I've talked to co-workers and they are seeing the same issues. So it isn't just me. So my question is:
Is this an issue with our video encoding?
Is it a bug with Chrome?
Or is it just localized to us?
Is there a way to deal with this besides switching back to Flash?
This is the flag I mean. If the flag is disabled, the browser tries to use hw-accelerated video decoding, which I can grant provokes wrong and slow video renderization in some devices. If enabled, hw-accelerated video decode is never used, but the above mentioned problems disappear. It theorically increases decoding time in devices actually able to use such acceleration, but I've been working around this field for almost a year and I still didn't realize any difference in that matter. Still didn't get to know how to identify if a device will behave properly (the availability of this feature doesn't seem to grant its proper behavior) with such acceleration without testing, though.

Two H.264 mp4 videos: One plays in Chrome, one doesn't

I have two different videos, both (as far as I know) generally captured in the same manner, that I'm trying to play using an HTML5 video tag in Chrome. Both videos open and play perfectly in VLC, so I don't think there's any issue with a corrupted file, and both are mp4's with an H.264 format, using YUV color space. However, when I try to play one in Chrome (Version 21.0.1180.89) it gives me a grayed-out play button, while the other works perfectly. For reference, my OS is Ubuntu 10.10, although I've seen the same problem in newer versions of the OS. This is whether I'm loading the video into the HTML5 tag, or navigating directly to the URL where the video is being stored. I'm somewhat at a loss here, does anyone know what direction I should go to find what the significant differences are between the two videos?
Edit:
This one works: https://dl.dropbox.com/u/100841270/1_G101_20120914_0139PM_Course_101.mp4
This one does not: https://dl.dropbox.com/u/100841270/1_G101_20120914_1156AM_Course_101.mp4
Update:
It appears to have nothing to do with OS, since I've seen the same problem in both Windows and Linux. Chrome 22 beta in Ubuntu didn't seem to work either.
We had this problem and found that encoding the files in accordance with iPhone's webview's standards created files that played fine in Chrome. Chrome and iPhone webview share the same render engine, and it appears they have similar HTML5 video requirements.
Not all H.264 encoded Mp4 files are supported by Chrome and slight differences in the encoding process can produce videos that do not work. Even if the EXACT same encoding settings were used, H.264 is a variable bit-rate encoder, so different videos may exceed bitrate limits.
The encoding settings that were successful for us were:
Only use the H.264 Baseline Profile Level 3.0
Resolution below 640 x 480 and framerate up to 30 fps
B frames are not supported in the Baseline profile.
bitrate limit of 900kb.
Here is the reference we used to arrive at those settings. Likely not all of these are required for Chrome, but we stuck to these rules and found that all videos worked on both platforms. Further research could likely determine the exact setting that is/was causing Chrome to not play the video.
I am running Windows XP, and chrome doesn't like the second one either.
My best guess of the cause is that, the working one is only 6.4 MB, but the other one is about 21.7 MB. Chrome might just be refusing to directly play a video that big. Have you tried having YouTube host it, and embedding their player into your site? That may solve the problem. (If you are worried about random strangers watching the videos, why did you post them here? Why would anybody even want to watch them? Though, you can make videos private on YouTube, in case these are just two videos that demonstrate the same problem you are facing with the real videos.)
That may also be compounded by a different problem that exists with both videos, manifested when I try to use Windows' built-in player. Both videos appear distorted when I use my computer's video player, stretched like 300% horizontally.
Are there other videos you have that fail in exactly the same way? Since these are only test videos for the real thing, if this is the only video with that problem, I would not say that it really is a problem unless it recurs. The dysfunctional video may have just run into that one-in-a-million chance that it has just the right contents for it to not work.

Cross browser OGG audio

I have to play an ogg audio file in the background when the user hits a "Music On" button. Currently the page uses an AUDIO tag, and it works in Firefox, but not in IE (confirmed by this table).
Is there a really cross-browser way to play an ogg audio file, if possible without Flash?
I am aware of the existence of specific libraries like JPlayer or SoundManager, but do I really have to use one of them? After all, it is just to play a sound...
Forget about cross-browser. Stick with ogg. It's much better than mp3 in every way. Tell people to change their browser to one which supports ogg (e.g. Chrome, Firefox, Opera). If they don't want to change, then forget about them; they don't deserve to hear your audio. If your client doesn't understand this, leave him and let him waste money on one developer after another until he finds a "yes man" developer who will give him a terrible website that will be a nightmare to use and will need completely redeveloped in a year's time.
The Company I work for has dropped support for IE6 for apps and websites and dropped support for IE7 when it comes to apps. Personally, I don't want to be developing for IE at all until I met a friend of mine working elsewhere. She was allowed to work from home, but she had to use RDP (Remote Desktop Connection in Windows) thats supported as a web interface only via IE. Some companies use Windows Group policies to disable USB drives etc. The terminals in these companies can have IE only! So as much as I would hate to admit, cross browser compatibility is a serious issue.
Flash would be the number one choice of plugin to play ogg files. Now, the following scenarios may occur:
iOS (iPad and iPhone) : HTML5 Audio Tag
Android / Chrome / Safari : HTML5 Audio Tag
Opera
Firefox
IE
For 3, 4 and 5 it really depends on the user. Even if they have one of Real Player, QuickTime or Windows Media Player, the would be able to play ogg files. There is a case where the specific ogg codec is not installed. In this case they will get a prompt on the top of their browser, telling them to install the specific codec.
We are talking about people insisting on using IE or insisting on a really really old version of firefox and who don't have WMP (by default on Windows), RealPlayer or QuickTIme installed but have an Internet connection.
Even jQuery leaves out 0.0001% of users ! :-P
You can probably consider using a .wav file, but I'm not sure that works.
The simple answer: no, there's no way to do it without Flash. My approach: simply create a script that converts a single file to multiple encodings.
