Struct CodecOptions 

pub struct CodecOptions { /* private fields */ }

Codec-private options, matching FFmpeg’s AVOption system.

Options are stored as string key-value pairs, parsed by each codec. Uses Vec<(String, String)> for deterministic ordering (required for FATE test parity — see CLAUDE.md).

Implementations

impl CodecOptions

pub fn new() -> Self

pub fn set(&mut self, key: impl Into<String>, value: impl Into<String>)

Set an option. If the key already exists, its value is replaced in-place to preserve insertion order.

pub fn get(&self, key: &str) -> Option<&str>

Get the string value for a key.

pub fn get_i64(&self, key: &str) -> Option<i64>

Get an option parsed as i64.

pub fn get_f64(&self, key: &str) -> Option<f64>

Get an option parsed as f64.

pub fn get_bool(&self, key: &str) -> Option<bool>

Get an option parsed as bool.

Recognizes “1”, “true”, “yes” as true and “0”, “false”, “no” as false, matching FFmpeg’s av_opt_set boolean parsing.

pub fn iter(&self) -> impl Iterator<Item = (&str, &str)>

Iterate over all options as (&str, &str) pairs.

pub fn is_empty(&self) -> bool

Returns true if no options have been set.
