A source’s camera colour profile.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Rec709

Display-referred SDR: honour the tags.

Hdr

HLG / PQ / Dolby Vision or wide-gamut SDR: libplacebo tone and gamut mapping.

DjiDlog

DJI D-Log / D-Gamut (Osmo Pocket 4) through DJI’s neutral Rec.709 LUT, else analytic.

DjiDlogVivid

DJI D-Log through DJI’s vivid Rec.709 LUT.

DjiDlogM

DJI D-Log M (Osmo Pocket 3) through DJI’s neutral Rec.709 LUT.

DjiDlogMVivid

DJI D-Log M through DJI’s vivid Rec.709 LUT.

CanonClog3

Canon Log 3 (Cinema Gamut).

AppleLog

Apple Log (BT.2020).

Implementations

impl Profile

pub const fn as_str(self) -> &'static str

The ffmpeg/libplacebo option name (bt709, pc, …).

impl Profile

pub fn from_picture(p: PictureProfile) -> Option<Self>

The camera profile for a container-level picture profile (crate::profile); None where ffcine has none yet (D-Log2, unknown).

pub fn detect_file(info: &MediaInfo) -> Self

The profile for a probed file: crate::profile::detect on its ISO BMFF metadata (DJI’s CAM meta colour mode, Canon and Apple tags; what the ingest catalog records) when that is at least medium confidence, else Profile::detect on the probe.

pub fn detect(info: &MediaInfo) -> Self

The profile the probe suggests (see the module docs).

pub fn camera_lut(self, dirs: &[PathBuf]) -> Result<Option<CameraLut>>

The camera LUT for this profile, None for profiles libplacebo handles from the tags. Vendor files are searched in dirs (see lut_dirs); Apple Log and Canon Log 3 fall back to analytic LUTs, D-Log M has no published curve and needs DJI’s file.

pub fn camera_lut_hdr(self, peak: f64) -> Result<Option<CameraLut>>

The camera LUT for an HDR deliverable: log -> BT.2020 PQ, mastered to peak cd/m², from the analytic curves; vendor LUTs only reach Rec.709. None for profiles libplacebo maps from the tags; an error for D-Log M (no published curve).

pub fn vendor_names(self) -> &'static [&'static str]

File names a vendor LUT for this profile may have in a LUT dir, preferred first.

Trait Implementations

impl Clone for Profile

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Profile

impl Debug for Profile

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Profile

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Profile

impl FromStr for Profile

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Error>

Parses a string s to return a value of this type.

impl Hash for Profile

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Profile

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
