jspsych-video plugin

This plugin is for showing a video. No responses are recorded. The trial concludes when the video finishes.

Parameters

Parameters with a default value of undefined must be specified. Other parameters can be left unspecified if the default value is acceptable.

Parameter	Type	Default Value	Description
sources	array	undefined	An array of file paths to the video. You can specify multiple formats of the same video (e.g., .mp4, .ogg, .webm) to maximize the cross-browser compatibility. Usually .mp4 is a safe option. The player will use the first source file in the array that is compatible with the browser, so specify the files in order of preference.
