What is your ffmpeg version

[russelltg]

This seems to be a bug in ffmpeg-next, this should workaround it

error: could not compile `ffmpeg-next` (lib) due to 2 previous errors

Huge caveat that I do not understand how Cargo.toml handles versions. The toml says "7.0.1" but the compile log references to "7.1.0"? Very confusing.

That's strange--this seems like a bug in ffmpeg-sys. What distro are you on?

Re cargo versions: version constraings are "semver minimums" in that any semver compat version is OK. So, cargo is allowed to select 7.1 when I specify 7.0 but it's not allowed to select 8.0.

I am using my own rolled distro (based on LFS). The compilation issue on v0.1.6 went away when I upgraded to FFmpeg 7.1.0 (the C library).
