Fields

index: i32

Stream index within the container.

codec_name: String

Short codec name (e.g. "h264").

codec_long_name: String

Human-readable codec name.

codec_type: String

Stream type: "video", "audio", or "subtitle".

profile: String

Codec profile (e.g. "High").

width: i32

Pixel width (video).

height: i32

Pixel height (video).

pix_fmt: String

Pixel format (e.g. "yuv420p").

level: i32

Codec level.

field_order: String

Field/scan order (e.g. "progressive").

color_range: String

Color range (e.g. "tv"/"pc").

color_space: String

Color matrix / space.

color_transfer: String

Color transfer characteristics (e.g. "smpte2084" for PQ).

color_primaries: String

Color primaries (e.g. "bt2020").

duration: f64

Stream duration in seconds.

bit_rate: i64

Stream bitrate in bits per second.

nb_frames: i32

Number of frames, when known.

r_frame_rate: String

Raw frame rate as a rational string (e.g. "25/1").

avg_frame_rate: String

Average frame rate as a rational string (e.g. "25/1").

sample_rate: i32

Audio sample rate in Hz.

channels: i32

Audio channel count.

channel_layout: String

Audio channel layout (e.g. "stereo").

bits_per_raw_sample: i32

Bits per raw sample (used to detect high-bit-depth/HDR content).

Implementations

impl StreamInfo

pub fn validate(&self) -> Result<()>

Returns an error unless this is a video stream with positive dimensions.

pub fn fps(&self) -> f64

Frame rate parsed from r_frame_rate (e.g. “50/1” -> 50.0).

pub fn resolution_str(&self) -> String

Returns "WIDTHxHEIGHT", or an empty string if dimensions are unknown.

pub fn hdr_kind(&self) -> Option<&'static str>

Detects HDR type from color metadata: "PQ", "HLG", "BT.2020", or None for SDR.

pub fn is_hdr(&self) -> bool

Returns true if the stream carries HDR color metadata.

Trait Implementations

impl Clone for StreamInfo

fn clone(&self) -> StreamInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StreamInfo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for StreamInfo

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
