Bug#739433: FTBFS with libav10

[Moritz Muehlenhoff]

Package: performous
Severity: important

Hi,
your package fails to build from source against libav 10 (currently
packaged in experimental). This bug will become release-critical
at some point when the libav10 transition starts.

Migration documentation can be found at
https://wiki.libav.org/Migration/10

Cheers,
        Moritz
