visionOS AVKit support for MP4 videos

When using .mov video files for creating video materials in RealityKit, they display correctly on my modelEntity. However, when I tried using a video file in the .mp4 format, I only get a solid black material. Does AVKit support playing .mp4 video files on visionOS 1.2?
