Currently beamcoder crashes when we try to access frame.data for videos with YUVA format.
Didn't really noticed this issue because we use filter https://github.com/Lumen5/framefusion/blob/main/src/backends/beamcoder.ts#L95
This filter helps because it always makes buffers squential
This requires additional time on CPU. This happens always even if input pixel format is equa output pixel format.
Ideally, we don't need to use those filters. we could get raw pixels data instead.
