Enum EncodingOperationError 

#[non_exhaustive]
pub enum EncodingOperationError {
    SendFrameError(EncodingError),
    ReceivePacketError(EncodingError),
    ReceiveAudioError(EncodingError),
    SubtitleNotPts,
    MuxerFinished,
    MuxQueueFull,
    EncodeSubtitle(EncodeSubtitleError),
    AllocPacket(AllocPacketError),
}

Errors from the encoder stage while turning frames into packets. Variants carrying an EncodingError 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.

SendFrameError(EncodingError)

Returned when submitting a frame to the encoder fails (avcodec_send_frame).

ReceivePacketError(EncodingError)

Returned when receiving an encoded packet from the encoder fails (avcodec_receive_packet).

ReceiveAudioError(EncodingError)

Returned when re-chunking buffered audio samples into encoder-sized frames fails.

SubtitleNotPts

Returned when a subtitle packet reaches the encoder without a presentation timestamp.

MuxerFinished

Returned when an encoded packet cannot be delivered because the muxer has already finished.

MuxQueueFull

An output stream buffered more packets before the muxer started than the pre-mux queue admits (fftools AVERROR_BUFFER_TOO_SMALL, “Too many packets buffered for output stream”). Unlike MuxerFinished this is a hard failure — never a silent truncation — so it must reach the scheduler error, not the graceful stop path.

EncodeSubtitle(EncodeSubtitleError)

Returned when encoding a subtitle fails (see EncodeSubtitleError).

AllocPacket(AllocPacketError)

Returned when allocating a packet for encoder output fails.

Trait Implementations

impl Debug for EncodingOperationError

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

Formats the value using the given formatter.

impl Display for EncodingOperationError

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

Formats the value using the given formatter.

impl Error for EncodingOperationError

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.
