Converting frames into a form displayable via wgpu

[Kirottu]

I am currently trying to write a video player widget for a GUI framework using this crate and wgpu, which requires me to convert frames to a suitable pixel format (like rgba) after they have been decoded.

I did this conversion using VideoFrameScaler, but after that I have no idea how to turn the data from the planes into an actually valid frame for wgpu.

A naive solution of just appending all the data slices together works for some videos, but not all.
