Cause
Web Isolation has a function which will validate the true file / content type of the video. As shown in the logs above, the accepted types are listed along with the detected type.
Resolution
This is considered a security feature and is enabled by default. However, it is possible to edit the list of accepted video types or turn off true type validation if desired.
This is managed under System Configuration > Gateway Advanced Settings > Edit > search for 'true'
The following shows an example where you can either add in application/octet-stream or disable the true type validation by un-checking the box:
