I want to extract DCT coefficients and motion vectors in a .mp4 video for encryption/ decryption. How do I read the video sequence to get the frames?

On Windows 7, you can use VideoReader to read a .mp4 file.
See the help for an example of reading one frame at a time.
If you have the DSP System Toolbox, or the Computer Vision Toolbox, you can use the System objects: signalblks.MultimediaFileReader or vision.VideoFileReader to read an mp4 file one frame at a time. If you have either of these products and want an example, write back (say which version you have, e.g. R2011b, R2011a, etc.)
