Video Player - MP4 Files

Hi

I have set up a mounted folder in Web Dev pointing to a server containing a bunch of static videos.

I point the Video Player Component to the url: http://xxx.xxx.x.xxx:8088/main/system/webdev/MyProject/Videos/testa.mp4

I can reach this URL and play the video successfully from any computer in my home. However, the file will not play on iOS iPad and iPhone on either Safari or Chrome.

Running Chrome://inspect on iOS results in the message ->>
“stack”:“play@…(perspective url with number)…The operation is not supported”

Has anyone got a static video working in Perspective?

Note - I tried re-exporting the file from iTunes as iOS compatible, but it said the file is already correct. I also tried a m4v version of the file without success. As I said, it does play perfectly in any desktop browser, so paths and sharing etc appear to be set up correctly.
