When building my project with stack I get this:

I'm unfamiliar with hsc, and the FFmpeg API, but it seems like the struct member codec has changed name or something. I read here that the API had changed significantly for version 4.4.

Thanks for flagging this! I suppose we’ll need to add CPP to support it.
