Struct ParametersLayoutShape 

pub struct ParametersLayoutShape { /* private fields */ }

Payload for DemuxError::ParametersLayoutShape.

The non-custom half of what a channel layout can be wrong about, and the half that went unchecked for eleven rounds of review on the argument that an order describing its channels through a uint64_t mask cannot be malformed. The mask is not the only field: nb_channels is an int a caller writes, and FFmpeg’s helpers compute nb_channels - popcount(mask) and take an integer square root of it without checking either.

See layout_preflight for the complete rule and why it is one function.

Implementations

impl ParametersLayoutShape

pub const fn new(stream_index: usize, order: i32, channels: i32) -> Self

Constructs a ParametersLayoutShape payload.

pub const fn stream_index(&self) -> usize

The AVStream.index whose layout declared it.

pub const fn order(&self) -> i32

AVChannelLayout.order, as the raw c_int it is on the wire.

pub const fn channels(&self) -> i32

nb_channels, as the layout declared it.

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
