New description:
`ay10` is used by a bunch of ATEM video switchers for still image frames.
It's a bit-packed (non-planar) variant of `yuva422p10` (similar to
`y210`?), where every two pixels are stored in two big-endian `uint32`s,
with 4:2:2 subsampling:
`(msb)2_ 10A 10U 10Y(lsb)` `(msb)2_ 10A 10V 10Y(lsb)`
I will attach a sample frame to this ticket once created.
The frames don't come in any proper container format – but they are
normally transferred with run-length encoding. I've unrolled the attached
frame and compressed it in a more "traditional" format.
The naming is just what their software calls it. I don't work for
Blackmagic Design, so I don't have any insight or influence into that. :)
I've attempted to write a patch for this (it's currently broken), which
I'll also attach. Unfortunately, `git send-email` doesn't seem to work
with OAuth2-authenticated IMAP/SMTP servers – it relies on application-
specific passwords, which are an unacceptably-large security hole for
2023. :)
