[FFmpeg-devel] [PATCH 2/2] configure: Check for AVCaptureSession as dependency to avfoundation

[Martin Storsjö]

This class is unavailable on tvOS before 17.0 (and macOS before 10.7
and iOS before 4.0, but those are fairly ancient). This makes sure
that we don't try to build the avfoundation indevice for such
OSes.
