We Keep Coding

how can I make the video part of this project work?

i am trying to make the code on the following page : https://github.com/gnuns/omigo work on my computer locally, and the text-messaging part works, but the video part doesn't.
I Have tried to manipulate the code my self, but i didn't find the solution yet, someone talled me that the code is depreciated, so i tried to learn about the webrtc, but only found old books.
there is no error message, just the browser ask for the permission to use the micro and webcam, and then nothing.

This is the security enforced by browser when the application tries to use media devices.

How can my web app user click a button to play a locally stored mp3 file?

I'd like to allow my users to click a button in a list of tunes on a page to open a simple mp3 player (the HTML5 Player is fine) that can play a downloaded mp3 track for that song that is stored on the user's hard drive. Is that even possible? Every attempt I've tried - using HTML and/or JS, JQ - fails.
I can copy the local mp3 file path/filename into my Chrome address bar. With no code at all it helpfully opens an HTML5 player in a new tab that allows me to play the tune just fine. Why is it so difficult to allow the user to do the same thing by simply clicking a button inside my app?
I have been able to get an mp3 player to appear on the page. But no matter how I specify the file path it refuses to play the tune - occasionally telling me my code is not allowed to access local files.

For security reasons, Javascript does not have the privilege to modify files, or even open files on the client machine.
If that is absolutely what you want to accomplish, try to use a JAVA Applet.

Thanks Lyes Ben. Over the last few days thinking about your comments has helped me understand that what I was attempting was not the right approach - and why. After some research I now believe that using the DropBox api I can code a simple 'drop-in-saver' function that would not only automatically save the files locally that my user would generate through the app, but would at the same time, provide another feature that was on my list - it would give the user offline access to those files. As a bonus the files would be synced on all the user's devices, with no additional code or complexity in the app.
Sometimes I get so focused on solving a particular technical problem that I fail to step back and ask if it is the right problem to solve in the first place.
It's not done yet but I'm now working on that DropBox interface to my app. I'll update this answer when (if) I get there as I suspect this could be a solution in some cases for others facing a similar problem.

prevent html5 video from being downloaded through inspect element

We have a module in our project where there is an option of uploading mp4 videos , we are using html5 video tag player for playing the videos.
Problem we are facing is the privacy of the videos.At the time its very easy for the user to download our file either through right click save as video or by taking the url from the src of the video tag by inspect element.
To do so I have studied a lot, and got the idea about the blob url through youtube videos which are not accesible through anyway.
I tried to study about the blob-url, created one for my video url but still they are accessible and can be easily downloaded. Like youtube blob-url its not working.
I also studied this ques question first answer, through which i got the idea about youtube mechanism of buffering video and how the blob url shown in inspect element for youtube is a spoof.
Most importantly I want to know how can we spoof our website url so that no one can download it through inspect element. Is it possible for us to do so and how? Any link related to this please share with me.I have tried to study a lot but still missing something.
What mechanism actually youtube follow for creating blob url and to save its videos?

As your video has to arrive at the users device there is effectively no way you can stop a user intercepting and storing the file if they want to.
The typical solution to this problem is to encrypt the file and only share the key to the encrypted video with the people you want to view it. A 'bad' user can still download the video file but will not be able to play it back without the correct key.
How you get the key to the users can be very simple (you tell them it directly via some separate communication channel, like email) or more sophisticated using some sort of DRM approach.
DRM is controversial (see Firefox discussion at link below) but it is being baked into the standards with HTML5 EME (Encrypted Meida Extensions) so is becoming more mainstream. EME essentially allow a browser request a trusted (by the video producer) element in the browser/device to decode and play an encrypted video. See a good overview of EME at the second link below.

RTSP stream for QuickTime player does not show movie

Did anybody faced to problem when QuickTime cannot play streaming video and shows blue question mark instead or errors - 400 (Bad Request) and 10060 (Disconnected)? I have already tried to switch getting stream from UFP to HTTP protocol with custom port in QuickTime settings but this did not help.
And does anybody know where can i find streaming video using RTSP protocol just for testing, links to online streams (not downloaded trailers) are appreciating.
These links do not work for me due to issue mentioned above:
http://mac.sillydog.org/qt/mov/embed_stream.php
And here only last one works (among other streaming types) :
http://quicktime.tc.columbia.edu/users/iml/movies/mtest.html
Thanks, for any links and advices.

The best way I've found to get rtsp streams to play in a browser window is using Apple's own javascript. I've tried hard coding tags with exactly the same parameters, and the embed tags won't work, but the js will. The js file itself is called AC_Quicktime.js. Just google it and you should be able to find a link to it easily enough. Use the one from Apple's site to make sure that you're getting unmodified code. Load that in your HTML page, and in your body, insert this:
<script>
QT_WriteOBJECT(*url*,*width*,*height*,*ActiveX Version*,*parameter1*,*value1*,*parameter2*,*value2*,*parameter3*,*value3*);
</script>
This will draw the appropriate code in whatever container you place the script. ActiveX Version can be an empty string (''), and as many parameters as you like can be entered one after the other. Apple has fairly exhaustive documentation on their website for all their stuff.Apple Developer Connection.
Hope that was marginally helpful.

it appears that this was just a security issue and stream was stopped by private policy of Quick Time so to turn on the ability to play RTSP stream in Safari i needed to check some option in browser settings ...

Play mms:// streams on my site

I'm building a "channel chooser" for a set of mms:// streams (Microsoft Media Server): a simple web GUI that lets the user chose which channel to listen to. For reference, here is the list of streams I'd like to use. I would like users to be able to play those streams on my site with a simple "play/stop" control. Nothing fancy.
How should I attack this? Any ideas or pointers appreciated! New angles and hacks around the problem too.
Javascript or Flash players are of course preferable, but I haven't been able to find any player that plays mms:// streams. My back-end language is Django if that helps anyone get any ideas.

MMS will require the user to have Windows Media Player installed. I believe you can embed mms:// content directly in an HTML page using <object> and/or <embed> tags and if it's installed, the WMP browser plugin will play the content.
Here's an Embedded Media HTML Generator; enter your mms:// url here and use the generated HTML in your video player page template.
