Errors from opening and configuring an encoder. Variants carrying an OpenEncoderError embed the mapped FFmpeg error.

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.

FrameSideDataCloneError(OpenEncoderError)

Returned when cloning frame side data into the encoder context fails.

ChannelLayoutCopyError(OpenEncoderError)

Returned when copying the audio channel layout into the encoder context fails.

CodecOpenError(OpenEncoderError)

Returned when opening the encoder fails (avcodec_open2).

CodecParametersError(OpenEncoderError)

Returned when exporting encoder parameters to the output stream fails (avcodec_parameters_from_context).

UnknownFrameFormat

Returned when the format of the frame to encode is unknown.

SettingSubtitleError(OpenEncoderError)

Returned when configuring subtitle encoding parameters fails.

HwSetupError(OpenEncoderError)

Returned when setting up hardware acceleration for the encoder fails.

ContextAllocationError(OpenEncoderError)

Returned when allocating the encoder context fails (avcodec_alloc_context3).

NoFramesReceived

Returned when the frame stream ends (EOF or upstream disconnect) before the encoder received any frame, so the encoder was never opened.

UnsupportedMediaType

Returned when the stream’s media type cannot be encoded (not video, audio, or subtitle).

ThreadExited

Returned when spawning the encoder thread fails, so the encoder never started.

Trait Implementations

impl Debug for OpenEncoderOperationError

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

Formats the value using the given formatter.

impl Display for OpenEncoderOperationError

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

Formats the value using the given formatter.

impl Error for OpenEncoderOperationError

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<OpenEncoderOperationError> for Error

fn from(source: OpenEncoderOperationError) -> Self

Converts to this type from the input type.
