Why won't embedded WebM videos display on my iPhone?

We understand that you may want to use the WebM format for media embed videos, as it's lightweight and offers built in transparency. However, iOS devices only offer partial support for WebM videos and as a result, you may encounter issues with WebM video playback and transparency.

One workaround we can suggest is encoding your video using VP8 or VP9 codecs. You can find out more about VP9 encoding here and tools like FFmpeg are available to assist you to export your WebM video with the required VP8 or VP9 codecs.

If you are using Adobe Premiere or other video editing software, we suggest researching how to export your WebM video with the VP8 or VP9 codecs using your chosen platform. 

Please be aware: this workaround optimises your chances of WebM videos playing normally on iOS devices. However, iOS compatibility can't be guaranteed and certain limitations may persist. We acknowledge this and encourage you to explore alternative options or consider re-encoding videos on their platform to maximise compatibility across all devices.

ARConnect experiences: We recommend using a VP8 codec
