Using MP3s in Ektron - ektron

Ektron 801 SP1
I am allowing users to upload MP3 files to their profile using the CommunityDocuments control. I want the user to be able to click the link and play the song. For some file types, such as .doc, the file downloads immediately because the URL of the link refrences "DownloadAsset.aspx". The MP3 files have a URL like http://www.domain.org/documents.aspx?id=242665652917&TaxonomyId=242665652152&LangType=1033&EkTB_iframe=true&height=520&width=790
How can I get these files to play? I have the following in the web.config
<add key="audio/mpeg" value="WindowsMedia"/>

As far as I know, Ektron doesn't provide any player / plugin support ootb for MP3 files. You can specify an additional MEDIA type in the web.config, perhaps. Or use HTML5 Audio. http://www.w3schools.com/html/html5_audio.asp
When using the HTML5 approach, pay attention to which codecs are supported by which browsers. You'll have to work out something else for older browsers via fallback or shim.
Adding a MEDIA type in the web.config will just tell the browser to load a plugin like quicktime or wmp, if it works at all.

As per eGandalf's answer, Ektron doesn't include an MP3 player. You should still be able to use Ektron to store and the serve up the MP3, by saving it into the library or as a DMS asset. You made need to update an Ektron config setting by adding ".MP3" to a file extension whitelist.
Regarding having a user player the MP3 in the browser, I would look at using JW Player - it's very popular and here is a tutorial on using it to play an MP3.

make it impossible to download the audio files

So guys, how do I prevent users from downloading audio files on my web app (running springboot in backend) by accessing the s3 url !
I want to make it impossible to download the audio files in my website ! Any suggestions pls ?
I assume you mean that you want to make it impossible to download the audio files, but still allow streaming them for playback.
You can't.
If it can be played, it can be downloaded. Simple as that.
At best, you can sign your S3 URLs so that they expire after a short period of time. This gives you control over who accesses your audio files, and prevents them from showing up in searches, or linked to from other sites. You can also look into Encrypted Media Extensions, but it's not all that useful for audio since audio is trivially digitally captured on the output.

IE10 not playing a video when using the <video> tag, but plays it when requesting the video directly

I have a webpage with a tag on it with the following markup:
<video width="456" height="360" controls autoplay>
<source src="Movies/Intro.mp4" type="video/mp4" />
<source src="Movies/Intro_H264.webm" type='video/webm; codecs="vp8.0, vorbis"'/>
<source src="Movies/Intro_H264.ogg" type='video/ogg; codecs="theora, vorbis"'/>
</video>
If I visit this page in IE10 it renders the video player but with an error message that reads: "Error: unsupported video type of invalid file path"
But what's odd is if I right-click on the video box and choose, Copy video URL, and then open a new tab in IE and paste in the direct URL to the video file (Movies/Intro.mp4) it plays in the browser without issue.
Also, I can visit the page using Chrome and it plays the MP4 video from the webpage without issue. All that to say, I don't think there's any issue with the video file itself or the encoding, but why is IE 10 not playing the video when it's in the tag, but it is playing it when requesting the video directly?
Any insights?
Thanks
I would check whether the mime-type is correctly being returned for the file.
Chrome will play correctly regardless of the MIME Type returned.
To check:
Press F12 to display the IE Tools Window/Pane.
Go to the Network Tab
Click Start Capturing
Browse to the page in question
Find the mp4 line
If the Type is displayed as application/octect-stream then this is your issue.
I had the same issue with IE 11 and the problem was the content type was application/octect-stream as stated by csmith. I was serving my videos from Azure storage and apparently that is the default content type.
You can change the type with Azure storage or using Azure api as shown in the post
Set Content-type of media files stored on Blob
Here is a guide for people on Amazon cloud (I did not test it)
Changing content type for Amazon
Make sure you set the web server to use MIME type video/mp4 for .mp4. I accidentally set .mp4 to use MIME type video/mpeg, the video plays in Chrome, but not in IE11.
I had this same issue which was a real pain in the ass. My solution was actually quite simple (after searching on the internet for about 4 hours).
Add this line (specific for IE) to your .htaccess file.
AddType video/mp4 .mp4 .m4v
When you paste the URL to your browser it doesn't use HTML5 player anymore, so it doesn't say that it is really a supported file; only that the file path should be valid.
According to wikipedia, IE10 supports (not only) H.264 for video and AAC for audio - these are very common formats for mp4 container. Chrome's support is much wider (video- and audio-wise).
The problem is that the Intro.mp4 file might have different formats altogether (the file could by just renamed or created using unsupported formats).
I'd look into the file using properties->details or third party programs (for example Media Info).
I don't think it is IE10's issue. The only similar one I've found is when the user was too specific using unsupported format of used codecs ([...] type='video/mp4; codecs="H.264, AAC"' [...]).
Now it is very easy to update mime type for your videos on amazon s3,
Just login and navigate to your file, under preferences you will see metadata, there you can edit content-type
Save it and reload your page.
If it directly plays find when you put the .mp4 URL into the browser make sure it's not running with the Quicktime plugin which you may have installed (especially if you use iTunes). Right click on the successfully playing video to rule that out. If it comes up with menu items related to Quicktime you may want to disable Quicktime plugin in adins and continue troubleshooting.

How use Video.js player via Flash fallback without CDN swf file

IE8 or older automatically uses flash fallback player but the player is hosted in CDN.
I want to use hosted video-js.swf file in my server instead of CDN contents.
Because CDN swf file is not secured.
The Video.js version is 3.2, that is currently you can download from http://videojs.com/.
I tried this code but it does not work.
Can someone help me with the solution?
Thanks!
Using the link, I was able to find a swf file listed in one of the links:
http://vjs.zencdn.net/c/video-js.swf

Where to save the uploaded files?

I am developing a web application to upload .mp3 files and need to play them. I successfully uploaded the files and saving them in C:/uploads folder. I understand that as it's a web application we need to save them in the Apache web server it self. But I am not sure, where to save them.
Thanks,
Serenity.
You can use content repositories to store uploaded data, I think this is common approach. For instance, take a look at the Apache JackRabbit CR, applying it you won't easy look for uploaded files on hard drive, but you will have web interface, and also some other tools available to connect to repository and show you files there etc.
As alternative to JackRabbit, you can try Alfresco CMS, they both implement JCR, other implementations are listed here (you will them at the bottom of that page).

Newbie question on Flash video players, products/SDKs, and API

I'm a C programmer and a total newbie to Flash/video/web world. Don't know where/how to start, and so would greatly appreciate your initial help.
Question
If I need to host flash videos off of my website (instead of embedding YouTube links on my webpages),
AND
If I need to provide player API like YouTube's that can be used, say, for supporting chromeless player versions customizable via this custom API of mine...
THEN
What do I need to do essentially...?
Write a custom Flash video player?
If yes, how? I mean, using which Adobe products / tools / SDKs / language(s)?
Is there anything free/opensource available for doing this? Especially, for Linux platform?
Write a new browser (firefox) plugin for users visiting my site?
Not sure how my custom Flash video player will get to the user visiting my site for the first time?
Any books, resources that cover this problem well?
Does the Flash content need to hosted off of a Windows server only?
Currently lost. Thanks in advance,
/SD
Flash has video playback support built-in, so all you need to do is use the Flash authoring environment or Flex to compile a .SWF file that uses the video API, with some buttons to stop and start the stream, volume, seeking, anything else you want your player to do.
Many people have already done this for you, in a way you can easily use from simple HTML. See eg. OSFLV, Flowplayer, JW...
Write a new browser (firefox) plugin for users visiting my site? Does the Flash content need to hosted off of a Windows server only?
Lord no! Flash video would never have taken off if it was just another custom-server+custom-plugin piece of unpleasantness. Though special streaming servers are possible, for the most part it's just an FLV file sitting on a web server.
(FLV is the video format supported by the Flash video playing functions. There are many, many tools you can use to convert other formats to it; I use Avidemux.)
If you are planning to use a "Progressive Download" approach, then your FLV files can be hosted on a Windows or a Linux box. Be aware that:
it is no as efficient as true
streaming.
you may not use it for live events
nor only for stored video files.
it cannot automatically detect the
end user's connection speed.
it is not possible to jump ahead to
another part while it's downloaded.
the video file will be saved on the
end user's computer.
If you are planning to use a "Streaming" approach then you can either buy and use Adobe's solution (Flash Media Server, available on both Windows and Linux box) or sign up for a hosted solution. On this page you will find recommended providers by Adobe. I personally have been using Influxis's hosting with success for a couple of years already.
You can also write your own streaming server but that would be a lot of hard work. If you are interested in that, I would recommend you have a look a Red5 which is an open source Flash Server written in Java.
