Enum SwChromaKeyError 

pub enum SwChromaKeyError {
    FrameRef(i32),
    UnsupportedFormat(Pixel),
    UnsupportedBuffer(&'static str),
}

Errors specific to SwChromaKey. Converts into the crate-wide Error via ? (see crate::error::Error).

Variants

FrameRef(i32)

FFmpeg could not take a second reference to the keyed frame already in hand, which is how an unchanged input picture is answered.

UnsupportedFormat(Pixel)

The input video is not in the BGRA pixel format required by this filter.

UnsupportedBuffer(&'static str)

The sink received a buffer other than decoded video or end-of-stream.

Trait Implementations

impl Debug for SwChromaKeyError

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

Formats the value using the given formatter.

impl Display for SwChromaKeyError

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

impl Error for SwChromaKeyError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<SwChromaKeyError> for Error

fn from(source: SwChromaKeyError) -> Self

Converts to this type from the input type.
