Hi, all. I'm starting an experiment where I need to have a video window, as well as a number of text boxes and buttons in a single GUI window. Is this possible? Does anyone have any example code or suggestions on how I might be able to embed the video into the GUI and control it?

Thank you kindly.

Bill

save above as a *.m file. Executing it should do your quest.

Chaowei, will this also play audio from the video files I'll be using? I have .avi files with audio, so I'll need the audio to play along with the video.

Thanks.

This seems to open my webcam. Any way you can provide me with code for importing my own video and playing it?

Bill 2011-8-27

Sorry, I missed your last comment. I should clarify. I don't need to record audio and video from a subject. I already have video files with audio saved and will need to play them depending on the trial the participant is on. Is there a function where I can import one of my .avi files into the workspace and then play it?
