VideoWrapper_EOS Details

The VideoWrapper_EOS API adapter allows VideoWrapper to support Canon EOS Digital SLR cameras driven by the Canon RC-SDK.

This initial version writes each captured frame to a temporary file. While undesirable, this shouldn't make much of a difference in performance as it takes multiple seconds to transfer a frame over USB 1.0.

If you experience odd errors, try power cycling the camera.

The Canon RC-SDK is required to build the VideoWrapper_EOS source and the run-times are required by the VideoWrapper_EOS binaries. Please visit http://www.canon.com/ to download.

The VideoWrapper_EOS API adapter is not currently included as a 'preset' in VideoWrapper. A call to VIDEO_loadLibrary() must be made to load VideoWrapper_EOS.dll.

The initialization string for VIDEO_openVideo() takes the following form:
