Inspect an ADΔER file
Want to quickly view the metadata for an ADΔER file? Just install this program for the current user with cargo install adder-info, then run with adder-info -- -i /path/to/file.adder -d. This program is analogous to ffprobe for framed video.
Currently, this only produces accurate data for raw (non-compressed) files. Compressed files will produce accurate header data, but the event counts and dynamic range will be incorrect.
The -d flag enables the calculation of the ADΔER file's dynamic range. This can take a while, since each event must be decoded to find the event with the maximum intensity and the minimum intensity. Example output:
Dimensions
Width: 960
Height: 540
Color channels: 3
Source camera: FramedU8 - Framed video with 8-bit pixel depth, unsigned integer
ADΔER transcoder parameters
Codec version: 1
Ticks per second: 120000
Reference ticks per source interval: 5000
Δt_max: 240000
