Want to quickly view the metadata for an ADΔER file? Just execute:
cargo run --release --bin adderinfo -- -i /path/to/file.adder -d
Alternatively, you can install this program for the current user with cargo install adder-codec-rs --bin adderinfo, then run with adderinfo -- -i /path/to/file.adder -d. This program is analagous to ffprobe for framed video.
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
