How can I receive stream video content over a network with UDP protocol?
I'm using Matlab 2015b, and I want to receive stream video from a Ar Drone Parrot. I have used MMS protocol to try receive stream video without success. I get an error because the format used by Ar Drone is MPEG-4 with H.264 encoded video and this protocol use the function "DSPWinMMFileInfo" which throws error.
So, I want to receive this stream video with UDP protocol, but I don't know how. I have seen examples to transmit audio data over a network with UDP, but not for video.
Please, can anybody help me? Thanks

Hi,
Can you post a snapshot of the error message you receive along with the code snippet that you are using.
The doc. link given below gives an example of sending video over network. Have you used something similar?
regards
Rakesh

I've uploaded a submission that supports streaming h264 (among other formats) from ip cameras.
% Connect to stream
cam = HebiCam('<address>');
% Continously display latest image
figure();
fig = imshow(getsnapshot(cam));
while true
set(fig, 'CData', getsnapshot(cam));
drawnow;
end
Let me know if this works for you.

The system object does allow you to read video content over MMS stream. However, the issue might be that it is unable to decode the H.264 stream that is contained in the video.
When you are using UDP, I noticed that the error indicates a permissions issue to access the socket. The system object error also indicates that it is unable to add the source for reading. This might be a permissions issue.
One quick thing to try is see if you are able to view this stream using Windows Media Player as the system object uses some of the same APIs to read it. Open Media Player, File > Open URL and try to stream data from your URL. If Media Player fails, then the system object is expected to fail.
Hope this helps.

Hi Maria,
I am trying to do almost the same thing. The difference is that I will have an embedded computer (ODROID XU4) with connected camera that streams video over UDP using gstreamer. Then, I would like to receive the video in MATLAB. I'd appreciate if any one can help.
Here is my email in case you find a solution.
Thanks.
