Force encoding method in expo camera

I am using react native and expo camera to build an app that can upload videos to my website. Everything works fine on Android but on newer iPhones, it uploads a blank video that still has audio. I think this is because of the new iOS encoding method HEVC rather than the typical H264. Is there any way to force expo camera to encode in H264? I couldn’t find anything in the documentation but I know there is a way to do this in react-native-camera but I am having trouble implementing react-native-camera. Any help is appreciated ASAP as I am on a deadline coming up very soon. Thanks!
