1//! A database of the pixel formats supported by FFmpeg and their size per pixel.

5/// Map from the pix_fmt identifier string (e.g. `rgb24`) to the number of bits
6/// per pixel (e.g. `24`). Returns `None` if the pix_fmt is unsupported/unrecognized.
7///
8/// Obtained from `ffmpeg -pix-fmts`.
9///
10/// ## Examples
11///
12/// ```rust
13/// use ffmpeg_sidecar::pix_fmt::get_bits_per_pixel;
14/// assert!(get_bits_per_pixel("rgb24") == Some(24));
15/// assert!(get_bits_per_pixel("asdf") == None);
16/// ```
