Error when loading an x265 video encoded with monochrome12 profile

[BioTurboNick]

I'm trying to load a video that was saved with this command:

imgstack = copy(reinterpret(UInt16, imgstack))
VideoIO.save("x265_lossless.mp4", eachslice(imgstack, dims = 3), framerate = 5, codec_name = "libx265", encoder_options = (var"x265-params" = "profile=monochrome12:lossless=1", preset = "medium"))

But I get this error:

ERROR: MethodError: no method matching out_frame_size(::VideoIO.VideoReader{true, VideoIO.GrayTransform, String})
Closest candidates are:

The workaround/solution is to define these methods:

out_frame_size(t::GrayTransform) = (t.dstframe.width, t.dstframe.height)
out_frame_size(r::VideoReader{TRANSCODE,GrayTransform}) = out_frame_size(r.frame_graph)

But perhaps GrayTransform and SwsTransform need a shared abstract type and methods should dispatch on the abstract type?
