In order to read video file using vision.VideoFileReader object, you need to initialize it:
video_source = vision.VideoFileReader('test.avi')
Now, to access a (next) frame of the video, you need to run the following command:
frame = step(videoSource);
If you are doing it for the first time after fresh Matlab installation, you will probably run into the following error:
Error using VideoFileReader/setup
Could not open the specified file.
This happens because Matlab is unable to find the correct codec to decode the video file. To solve this problem, follow these steps:
video_source = vision.VideoFileReader('test.avi')
Now, to access a (next) frame of the video, you need to run the following command:
frame = step(videoSource);
If you are doing it for the first time after fresh Matlab installation, you will probably run into the following error:
Error using VideoFileReader/setup
Could not open the specified file.
This happens because Matlab is unable to find the correct codec to decode the video file. To solve this problem, follow these steps:
- Install ubuntu-restricted-extras
- sudo apt-get install ubuntu-restricted-extras
- Install Gstreamer
- sudo add-apt-repository ppa:gstreamer-developers/ppa
- sudo apt-get update
- sudo apt-get install gstreamer0.10-tools gstreamer-tools gstreamer0.10-plugins-base gstreamer0.10-plugins-good gstreamer0.10-plugins-bad
- Install gstreamer0.10-ffmpeg
- sudo add-apt-repository ppa:mc3man/trusty-media
- sudo apt-get update
- sudo apt-get install gstreamer0.10-ffmpeg
Restart the Matlab and it should work just fine!
Enjoy!
Hola... En MAC como podrĂa ser? Gracias.
