Troubleshooting errors with video files

The video file formats that are compatible with Imatest vary based on operating system and installed codecs. For a list of video file formats compatible with Imatest, please see the image file formats and acquisition devices documentation page.

If you are working on Windows and using a video file that is listed as compatible with Imatest and see the following error:

Reference to non-existent field ‘hVideo’.

Then you may not have the appropriate codecs installed. Installing K-Lite Codec Pack Basic may resolve this issue.

If, after installing the appropriate codecs, you see the following error:

Error using VideoReader.read
Expected index to be a vector.

You need to update to Imatest 4.1.3 or later.
