If no students can view:
→ Video is likely in a folder that doesn’t allow for shared permissions (Videos must be placed into a course folder that is tied to a GauchoSpace course page. Only students enrolled in that GS course can access the videos in the GC folders.)
→ Permissions on said video might be locked down.
Once you move the video into the appropriate course folder, it should be viewable by all of the students enrolled in your course.
This article walks through moving your video file in GauchoCast:
If only some students can view and not others:
1st- Please make sure that the video is in your provisioned course folder. Videos stored in a personal folder will limit who can see the content.
2nd- Verify that the students who do not have access to the video are currently on your class roster in GauchoSpace.
3rd- Advise students to try accessing the content through the GauchoCast block on your GauchoSpace page. This will update their viewer permissions.
If none of these options work, you can also change the sharing permissions on their videos to "anyone at this org. with a link." This method will still require viewers to log in to view the video. The only way to find the videos in the first place would be to directly get there via a link. Which can be shared to students via GauchoSpace.
