Calculate largest value from histogram to use as fallback for clips with missing MaxSCL information. Note that this may end up picking the "reserved" value at the 5% percentile, which in practice appears to track the brightest pixel in the scene.

◆ ff_test_fmt()

int ff_test_fmt ( SwsBackend backends,

const SwsFormat * fmt,

int output )

Statically test if a given format is supported by the given set of backends.

This is a heuristic, which may have false positives if a specific backend does not actually implement all operations that would be required to support the format.
