segfault

After applying a temp fix for #17 by adding the following to the Dockerfile:

`COPY --from=build /usr/lib/librav1e.so /usr/lib/librav1e.so.0`

The compilation completes correctly. No matter what I do I get a segmentation fault upon running the ffmpeg process within the container. I've tried a few options like building from snapshot (hit other issues with aom) and using the latest stable ffmpeg version (6.1) but to no avail, still get a segmentation fault.
