Compatible alpha video formats?

Hi Federico,

Thank you for the sample project. I ran into trouble when trying to use my own transparent videos - the app crashes.

Your transparent video file MuseoMarAnimacionAlpha.mov works fine, so I am interested to learn which process you used to create the video. Both Finder and ffprobe report that it uses H264 codec, but from what I was able to gather online, H264 videos should not support alpha channel. What's the trick? Ideally, I would like to use H265 videos with transparency, but when I try to use any such video file (including test videos provided by Apple), the app crashes in the moment when the video should start playing with the following error:
validateFunctionArguments:3838: failed assertion `Fragment Function(FastSingle_FragFunc): missing sampler binding at index 0 for u_texture_sampler[0].'

Somebody else mentioned the same crash message here on StackOverflow.

Won't accept any other videos

I'm trying to load my own mp4 or mov, but all I get is a white box instead of the video to play on the recognized image. The videos included with the demo play fine. Can you assist please?
