C# Streaming from Panasonic IP camera using RTSP

I want to receive an RTSP stream from a Panasonic camera (Model WV-SPN531) and display the live video in my C# Form application.
If I use VLC and connect to "rtsp://IP_ADDRESS/MediaInput/h264/stream_1" the streaming works fine.
Codec: H264 - MPEG-4 AVC (part10) (h264)
Resolution: 1920x1080 (15 FPS)
I have tried this library, but it does not work: http://net7mma.codeplex.com/ .
I wrote to the developer of the library and I described the problem and he replied that: "There's not an available MPEG decoder in C# right now, not one which I know of immediately anyway."
Can you help me?

I have used this SDK to play RTSP video in C#
https://sourceforge.net/projects/onvifdm/files/%21sample_winform/
It uses a hosted executable to play the video but works very well
I also tested https://github.com/ZeBobo5/Vlc.DotNet before hand but the performance was a bit choppy compared with the above.

I am using the Datastead Rtsp source SDK to capture Panasonic, Axis and some other IP cameras.

Streaming audio spereated from a video over network to android device

I have a video file and I want to play it on one computer (preferably with C#), but stream the audio to an android device and let it play there synchronous to the video content over network.
Do you have any tips how I can achieve that?
Any library or code examples are welcome :)

Effective video stream compression in C#

I am looking for a effective way to compress a real time video stream. In my project, the streaming seems important because my system will send and receive both the audio and video streams at the same time. I am considering using H261 or H263. How can I achieve such compression ratio using C#?
PS I found something called H323Plus, but I do not know how to call this library because it is written in C++.

If you want to do real-time streaming over UDP with both audio and video stream you can use the DirectShow API (if you're targeting Windows).
http://msdn.microsoft.com/en-us/library/windows/desktop/dd375454(v=vs.85).aspx
You will find a .NET wrapper for DirectShow here
http://directshownet.sourceforge.net/
You will also find more samples on codeproject.com, most of them use this wrapper

If you plan on targeting Windows 7 and newer only, then you will want to use Windows Media Foundation API

Axis Camera video streaming with C# 64bit

I'm looking for a way to stream video from an AXIS M10 IP camera, and display the feed using windows forms (or better, wpf). However, it need to be running on 64-bit platform.
This means that I can't use the AXIS Media Control ActiveX component.
Also, I found that these methods work but only in 32bit environment:
1.Using MediaElement Class for WPF
2.Using embedded media player
3.VlcLib (for dotnet)
So far it looks like my only option is to directly implement RTSP protocol and decode the given RTP/AVP stream using Media Foundation (for .net) and display it somehow. (I was able to get the camera to stream to a UDP port using RTSP calls).
I'm fairly new to RTSP/streaming, so I'm concerned that I might be missing the big picture - Will I be able to use media foundation to render/display videos on winform/wpf, or do I have to look at that functionality elsewhere?(from my research it looked like it could decode H.264 streams, but I did not see any video-playing capabilities). I also came across DirectShow - should I use DirectShow over Media Foundation?
Or better yet, is there a library that is able to handle RTSP streaming that runs in 64bit?

VisioForge Video Capture SDK .Net for example (but commercial), WPF controls included.
Decoding using FFMPEG, with DirectShow engine. Really, I don't see any Media Foundation advantages here.
Also any other way using FFMPEG.
Or, you can write RTSP source filter (based on DirectShow Push Source sample) with H264 output pin for video and G726/G711/AAC for audio. Also you can made virtual video capture source filter and use it in MF or DirectShow. You can use live555 library for RTSP implementation.
So, no simple ways here, if you are starting from zero.

If you just need the Video, I would prefer to just display the MJPEG stream of the camera. This is really easy done without the complexity of DirectShow or MediaFoundation. I display 12 cameras at the same time in my application with this little library in WPF: MJPEG Decoder. You can also use it in WinForms. It decodes the MJPEG Stream and gives you the images to display.

The 64 bits Axis Media Control SDK is available now, but requires an account on Axis web site to be downloaded.
After Sign in, you need to join Axis Developper program (free) and download the AMC SDK.
You will install a executable file (.exe), this install all the libs and samples in your Drive
C:\Program Files\Axis Communication\SDK

I found a way to use VLC in 64bits without ActiveX DLL :
The VLCSharp Library is composed of multiple NuGets to use VLC Player on severals platforms (WPF, Winforms, Xamarion, TvOS).
It is working fine on Onvif Cameras

How do I encode an image in H.263 and send it in real time using udp

I am building a sip softphone in C#, I am through with the audio aspect, but I want to add video call capability to it, I can successfully get image from the webcamera on the system, but the problem now is I want to compress the image using h.263 codec algorithm before sending it over udp in realtime, all the codes I have been seeing on h.263 is in c++, and I am not a C++ person, please how can I implement this in C#, I mean get the video from the webcamera, encode in h263 and send it over wire in realtime, any suggestion will be highly appreciated

If you want to do real-time streaming over UDP with both audio and video stream you can use the DirectShow API (if you're targeting Windows computers). Official documentation available here: http://msdn.microsoft.com/en-us/library/windows/desktop/dd375454(v=vs.85).aspx
You will find a .NET wrapper for DirectShow here: http://directshownet.sourceforge.net/ and also some samples.
You will also find more samples on codeproject.com, most of them use this wrapper: http://www.codeproject.com/kb/audio-video/#DirectShow
Using DirectShow you will be able to capture both the webcam and the microphone in realtime, encode them using the appropriate encoder filter (for instance, a h263 encoder for the video stream) and then send the encoded frames over the network using a RTSP writer filter.
I'm not an expert on DirectShow, but this could be a good starting point. I know this solution works because I've implemented it few months ago.
You need to know that DirectShow is beeing deprecated since Windows Vista, and is beeing replaced by the new API: Windows Media Foundation. If you're targeting Windows Vista or Windows 7 only, it may be a better choice to use the new API. See the MSDN documentation for more details: http://msdn.microsoft.com/en-us/library/windows/desktop/ms694197(v=vs.85).aspx
Hope this will help you.
