Function ffmpeg_sys_next::av_hwaccel_next

pub unsafe extern "C" fn av_hwaccel_next(
    hwaccel: *const AVHWAccel
) -> *mut AVHWAccel

If hwaccel is NULL, returns the first registered hardware accelerator, if hwaccel is non-NULL, returns the next registered hardware accelerator after hwaccel, or NULL if hwaccel is the last one.

@deprecated AVHWaccel structures contain no user-serviceable parts, so this function should not be used.
