The latter is required by image-rs/image#1398
There was a problem hiding this comment.
The amount of unsafe in decoder is not yet very reassuring, particularly without safety comments. If that combination, deriving a slice from the plane_data_ptr and plane_data_geometry, is always safe then I'm wondering why this is not an abstraction provided in the dav1d crate?

There, both the mp4parse and dav1d crates got a release, I’ve updated this PR to use the non-git version. |

This encoder so far only supports 8-bit data, and due to #1217 is much less efficient than it could be, as data is always converted to BGRA8888. I could also add support for I8 and IA88, but those formats are uncommon enough we can probably ignore the inefficiency for a first version.
This is 5am quality code, so no error handling but
.unwrap(), and there are someunsafeblocks which could possibly be avoided, I will get back to it after a first round of review.This also depends on mozilla/mp4parse-rust#266 to build.
Fixes #1152.
