Reconyx Hyperfire 4K - Maker notes changed, plus solution #454
Description
Hello Drew. Reconyx just came out with a new camera the HyperfFire4K, where the MakerNotes have changed. I was able to get the specs for them. Their document also covers these cameras:
-RapidFire/HyperFire/MicroFire/HyperFire2/HyperFire4K
MetadataExtractor currently cannot extract the HyperFire4K maker notes. If you want to include that camera in your next version, here are the specs. For what its worth, I also informed ExifTool about this, who are acting on it.. My own .Net software (https://timelapse.ucalgary.ca) allows a user to first try ExifTool (which is faster) and then fallback to ExifTool(which is slower but tends to address more cameras). Both your tools are great!
7.1 HyperFire 4K MakerNote Definitions
| Term | Description |
|---|---|
| uint32 | unsigned 32 bit integer (little endian) |
| uint16 | unsigned 16 bit integer (little endian) |
| int16 | signed 16 bit integer (little endian) |
| uint8 | unsigned 8 bit integer |
| char | 8 bit character (ASCII) |
7.2 HyperFire 4K MakerNote Structure
The EXIF specification states that the contents of this field are up to the manufacturer and the
type must be UNDEFINED. For RECONYX HyperFire 4K cameras the MakerNote tag has the
following structure.
