This XBlock allows for edX components to be displayed to users inside of videos at specific time points.

Install the requirements into the python virtual environment of your edx-platform installation by running the following command from the root folder:

$ pip install -r requirements.txt

You can enable the In Video Quiz XBlock in Studio through the advanced settings.

1. From the main page of a specific course, navigate to Settings -> Advanced Settings from the top menu.
2. Check for the advanced_modules policy key, and add "invideoquiz" to the policy value list.
3. Click the "Save changes" button.

For this xblock to function properly, the course author must add to the unit:

a video to be played a problem to pop up at a specific time moment (or several problems) an in-video-quiz xblock (from the list of advanced components) (see the screenshot below).

The in-video-quiz block must be edited as follows:

• the very last part of Component Location ID of the Video block (not the Video ID!) should be copied from the settings of the video and pasted into "Video ID" field.
• the very last part of Component Location ID of the Problem block should be copied from the settings of the corresponding problem(s) and inserted into the dictionary-like JSON structure in the 'Problem Timemap' field (see the screenshot below).
• blocks order within the Unit matters (in-video-quiz block must follow after the video block and problems / quizes).

NOTE: The key "5" in the dictionary corresponds to the 5th second (0:05) of the video.

When a student is logged in, only the video is displayed initially:

At the time moment indicated by the course author in the in-video-quiz xblock settings (5th second in this example), the video is paused and is replaced by the quiz (problem):

NOTE: The video can be resumed by pressing the 'Continue' button.

When a staff member is logged in, the video is displayed along with the problem(s) to be shown in it. Each problem is supplied with indication of the time moment, when it appears in the video:
