Comment (by logiclrd):
I suspect this is waiting for this: https://trac.ffmpeg.org/ticket/7965
My understanding, in short: The integrated x265 decoder in FFMPEG doesn't
yet have support for alpha channel data, so it gets lost during decoding
and the internal bitstream is YUV and not YUVA. When the decoder starts
supporting alpha data, I think converting to PNG frames with alpha will
//probably// just work.
