Hello, I’m using a laptop with a PCMCIA framegrabber card (Imperx VCE-PRO) along with a Zeltom Hilink development board that communicates over RS232. Plz any one help me and rpl me as fast as u can :-s.
#Matlab 2009 video reader code#
My problem is that how can i run this code by interfacing camera and play it in real time instead of running sample videos which is in AVI format. Motion capturing and calculate its center point (x and y coordinates) If You are new to parallel ports read here.Ĭomment your thoughts, don’t keep them to yourself!!! That’s it, now that you have the image of what your robot is looking at or probably the desired object, you may carry on processing and provide proper control signals to your Parallel Ports. This command will store the image of that instant into the variable data in a matrix of 320X240. And you will be able to view the video demo the webcam at runtime This will open a window similar to yahoo messenger Webcam interface. Vid = videoinput(‘winvideo’, 1, ‘RGB24_320x240’) Ģ) Open Preview window to view video at runtime Now the main partġ) Connect your webcam to the computer through the USB. Type “imaqhinfo” in command window to see thisĪny webcam you connect is accessed through this adaptor. Get Matlab 7.You must check if you have the data acquisition toolbox in your version. Well this can be easily done through MATLAB.

This will hopefully allow you to use VideoWriter once you install the codecs.Have you ever wanted to process your image and then do some processing and then move your robot? The above website contains all of the codecs you would need to play video files in Windows. I know you said that when you installed codecs, it didn't work but you can try the above link if you haven't done it already.

Since you're running Windows, one suggestion I have is to install the Windows 7 Codec Pack suite. As such, you will have to use one of the provided profiles that MATLAB has for you. If you don't see MPEG-4 on your list of profiles, then you currently don't have the profile installed. Uncompressed AVI An AVI file with uncompressed RGB24 video data
Motion JPEG AVI An AVI file with Motion JPEG compression Motion JPEG 2000 Video file compression with JPEG 2000 codec. MPEG-4 A MPEG-4 file with H.264 Compression Indexed AVI An AVI file with Indexed Video Data Grayscale AVI An AVI file with Grayscale Video Data Summary of installed VideoWriter profiles:Īrchival Video file compression with JPEG 2000 codec with lossless mode enabled.

For example, I'm using MATLAB R2013a on Mac OS and this is what I get: > profiles = VideoWriter.getProfiles() You get a list of all possible profiles that you can use for writing a video to file using VideoWriter. Run the above code in the Command Prompt. You can verify this by doing this in MATLAB: profiles = VideoWriter.getProfiles() This is due to the fact that you probably don't have the MPEG-4 codecs installed on your computer.
However, you are getting this error: Error using VideoWriter (line 168) The specified profile is not valid. so doing: vid = VideoWriter('TestVideo.mp4','MPEG-4') You need to use the second way of invoking VideoWriter. Uninstalling Matlab 2009a is not an option. I have further tried to find out what videoWriter does regarding asyncio, but cannot find any clues in the code, and I honestly don't really know what asyncio is. I have tried to add the asyncio folder in the Matlab directory to the Matlab path, but again no luck. I read somewhere that someone had a similar problem, and it was due to a corrupt path and it could be caused by an older installation of Matlab (2007), but nothing about what was eventually done to fix it. I tried installing codecs, but that didn't help. Now if I do this: vid = VideoWriter('TestVideo.mp4','MPEG-4') Undefined variable "asyncio" or class "asyncio.Channel". My code fails here: vid = VideoWriter('TestVideo') I also have Matlab 2009a installed (which could be the issue)

I am trying to use videoWriter in Matlab 2013a on a Windows 7 64 bit machine.
