I know people have asked this before, but i see no answer nor people even commenting about it.
So, i'm trying to make SHOUTcast streaming in WP7, anyone have done it? I know i have to use MediaStreamSource with my MediaElement, but how exactly can i skip that header from SHOUTcast and just get the stream and use it in a MediaStreamSource? Is there any app that has done it? Someone actually has some example working code?
There is a really good SHOUTcast Player called streamything (http://www.streamything.com/page/en/default.html) . Unfortunately it is not open source nor freeware but i shows that it is definitely a way to do that.
You need to setup a mechanism to get the stream of data to be passed to the application continuously. Here is a possible implementation. In order to be able to receive the stream directly (so that the application won't be treated as a web browser), you have to call the URL with a semicolon at the end. For example: http://00.00.00.00:8000/;

This is a very simple task that I had such a hard time trying to do. My goal is pretty simple: send an mp4 file from my server to my client, and while its buffering and downloading I want to already play it. That means that I need to play a video.mp4 file while writing it, and I need it to display on some platform that I can control - like wxPython or WPF-Ironpython. Naturally, no such platform will let me play an open file for writing.
I have tried to implement and HTTP server (although totally unnecessary for my case, as I am writing an application-based Server-Client app) that would accept Range request, and when I run the server and load the URL on Chrome, it all works perfect and I can seek and buffering is great, but when I load it from WPF MediaElement it fails to play the video for some point (I cant really tell why as there is no documentation for this, any API, tutorials etc). I am really desperate.
I even thought about playing a video from a buffer and then just changing the buffer's content, but it doesn't seem like this possibility exists.
I am really stuck at this and I would love to get some suggestions. Please note that I am not a professional in this so I would appreciate if you could explain this to me in simple terms.
Thanks!
Not possible. MP4 is not the correct container for your application. You must use something like HLS/dash/fragmented MP4.
I am working on project in which I use Sipek Voip for connecting to Freeswitch. Here is the situation:
I have a Sangoma A400 hard. I compiled Freeswitch for Windows and now it works perfectly.
I have also created a Softphone using Sipek Voip SDK and it works well with Freeswitch.
The problem is that, when I have an incoming call, instead of showing the callers number, I get mod_sofia.
I looked at Sipek and all it gets from pjsip is a string containing <sip:mod_sofia#192.168.2.10:5060>.
So I went to pjsip and tried to pass the actual phone number to Sipek. I found out there is a function called pjsua_call_on_incoming which handles an incoming call.
It takes an argument of type pjsip_rx_data. It has a string field (rdata->msg_info.msg_buf) which contains the whole message. I tried to replace <sip:mod_sofia#192.168.2.10:5060> with the actual number, but it has no effect.
Does anyone have any idea how to fix this?
You can check this link for tracking the issue. Unfortunately there are hardly any people who can help you out with Open source projects "for free" even on a forum. I just speak from my personal experience. I am facing the same problem, and cannot figure it out till now, though I have solved many issues that I used to face with SIPEK, all on my own.
I've not understood the root of your problem is in FreeSWITCH or in sipek/pjsip.
This entry on FreeSWITCH wiki could help you debug the sip stack in FreeSWITCH:
http://wiki.freeswitch.org/wiki/Mod_sofia#Debugging_Sofia-SIP
in a way similar to a wireshark capture.
I'm sorry I don't know how to help you trace down the parsing/rendering of msg_info.msg_buf in pjsip.
Add sip_contact_user=xxxx in your dialstring.
I want to make project for my final year in college.
So someone suggested me to make Remote Desktop in C.
Now I know basic socket functions for windows in C i.e. I know how to make
echo server in C.
But I don't know what to do next. I searched on internet but couldn't find
something informative.
Could someone suggest me how to approach from this point..any tutorial...or any source ?
I think this is do-able. For a college project, you don't need to have something as complex and as full-featured as VNC. Even demonstrating simple keyboard and mouse control and screen feedback would be enough, in my opinion, and that's well within reach.
If you're doing everything from scratch and using Win32, you can get the remote screen using the regular "printscreen" example all around the internet.
http://www.codeproject.com/KB/cpp/Screen_Capture__Win32_.aspx has it, for one. You can then compress the image with a third-party library, or just send it raw; this wouldn't be very efficient but it would still be a viable demonstration.
Apart from capturing the screen data remotely and showing it in the local window, you'll need to listen for local window messages for mouse and keyboard events, send them to the remote host, and then play them back. http://msdn.microsoft.com/en-us/library/ms646310%28VS.85%29.aspx will probably do that for you.
Check tightvnc TightVNC is a free remote control software package. The source code is also available.
For sending the image of the screen I would probably use rtp. The JRTPLIB is really handy for that.
And yes, as KevinDTimm says, an echo server is the very easiest part.
KevinDTimm may well be right, writing an RDP client would a fairly significant undertaking. To give you some idea, the current spec, available at the top of this page, is 419 pages long and includes references to several additional documents for specific aspects of RDP like Audio Redirection and Clipboards.
i am developing a video player i silverlight
i wanna something to prevent recording or screen capturing
i thought about hacking the windows APIs and stop my program from running if there was any of those capturing software asking the user to close it first but i donno how to do this
is there another solution ??!!!!
It's simple not possible. If you try it, you're only going to annoy people.
Even 'hacking the windows API' would not work, since the OS itself could be run inside a VM.
I hate to be a downer, but task is impossible to fully accomplish.
If you were somehow able to hook the keyboard (from a silverlight app no-less) I would certainly hope that whatever AV the user is running would throw up some red flags.
Also what if the user doesn't use the standard (alt)+prtscr? A third-party tool might use a different key-combo. Also, I've written a screen-grabber with the GDI+ API, and there's no way to disable something that low-level.
What about attached capture-cards? What if your app is running in a VM or over remote-desktop?
If you are that deeply concerned about protection your HD content, watermark it, or make the user pay for it first.
All-in-all, as soon as your content's data enters your user's computer, they can duplicate it.
You could go about using a key hook system, stopping the user pressing the print screen key on the keyboard, that would be a start. There aren't many systems which stop users from print screening video specifically. You might want to try just watermarking your video instead? At least then people know that the video was originally sourced from you.
The solution is not to allow your application to run on a computer, but instead target a device such as a phone. Computers will always allow some kind of screen capture and video capture but this is much harder and less likely to be tackled if you restrict to only playing on certain devices.
How badly do you need this? There are many ways to defeat screen capture protection: for instance, aiming a video recorder at the computer screen (or looping output to a TV with a capture card, etc. etc. etc.)
Go for a commercial solution if you really really need this: don't have any experience with those myself, however.
I have some C code that parses a file and generates another file of processed data. I now need to post these files to a website on a web server. I guess there is a way to do a HTTP POST but I have never done this in c (using GCC on Ubuntu). Does anyone know how to do this? I need a starting point as I have no clue of doing this in C. I also need to be able to authenticate with the website.
libcurl is probably a good place to start.
I think Hank Gay's suggestion of using a library to handle the details is the best one, but if you want to "do it yourself", you need to open a socket to the web server and then send your data in the HTTP POST format which is described here. Authentication can mean a variety of different things, so you need to be more specific.
Unfortunately, all of the above three jobs involve a fair bit of complexity, so you need to break the question down into stages and come back and ask about each bit separately.
