Video Reader: Failed to initialize internal resources

I am trying to read an MP4 video file from a GoPro camera.
The following error shows up when using VideoReader...
v = VideoReader(fullfile(files(ia).folder,files(ia).name));
Error using VideoReader/initReader
Failed to initialize internal resources.
Error in audiovideo.internal.IVideoReader (line 136)
initReader(obj, fileName, currentTime);
Error in VideoReader (line 104)
obj@audiovideo.internal.IVideoReader(varargin{:});
The video codec is MPEG-H Part2/HEVC (H.265) (hcv1)
The audio codec is MPEG AAC Audio (mp4a)
My guess is that H.265 unsupported? Can anyone confirm?
The audio codec appears to be supported.
The video plays on VLC so I assume I have the codec installed.
I am using Windows 10 Enterprise 22H2, Matlab 2022a
Is there anything that can be done to get VideoReader to work with this file?

Yeah, it seems that H.265 is unsupported for this. You can use ffmpeg to convert it to H.264 for your task.
ffmpeg -i input.mp4 -vcodec libx264 output.mp4
If you want to do it from MATLAB, there's ffmpeg toolbox. I'd suggest looking into its usage and then using VideoReader on the converted file.
