When downloading the latest qsv release, I get an "Egress is over the account limit" error.

GitHub has been very generous with hosting resources for open source projects like qsv.

Of course, they only do so within limits. So just wait a few minutes, and try downloading again in a bit.

If the problem persists, contact GitHub support as they've been known to lift these limits if asked nicely. 😄

Alternatively, qsv can also be installed using Homebrew. Note however, that the homebrew version only has the apply and luau features enabled.
