pub enum DecodingOperationError {
    FrameRefError(DecodingError),

Errors from the decoder stage while turning packets into frames. Variants carrying a DecodingError 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.

FrameRefError(DecodingError)

Returned when creating a new reference to a decoded frame fails (av_frame_ref).

FrameCopyPropsError(DecodingError)

Returned when copying frame metadata fails (av_frame_copy_props).

DecodeSubtitleError(DecodingError)

Returned when decoding a subtitle packet fails (avcodec_decode_subtitle2).

CopySubtitleError(DecodingError)

Returned when copying a decoded subtitle for delivery fails.

SendPacketError(DecodingError)

Returned when submitting a packet to the decoder fails (avcodec_send_packet).

ReceiveFrameError(DecodingError)

Returned when receiving a decoded frame from the decoder fails (avcodec_receive_frame).

FrameAllocationError(DecodingError)

Returned when allocating a frame during decoding fails.

PacketAllocationError(DecodingError)

Returned when allocating a packet during decoding fails.

SubtitleAllocationError(DecodingError)

Returned when allocating an AVSubtitle during decoding fails.

CorruptFrame

Returned when the decoder emits a frame flagged as corrupt and corrupt frames are treated as errors.

ErrorRateExceeded

Returned when the ratio of decode errors to decoded frames exceeds the maximum allowed rate.

HWRetrieveDataError(DecodingError)

Returned when downloading a hardware-decoded frame to system memory fails (av_hwframe_transfer_data).

CroppingError(DecodingError)

Returned when applying codec cropping metadata to a decoded frame fails.

Trait Implementations

impl Debug for DecodingOperationError

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

Formats the value using the given formatter.

impl Display for DecodingOperationError

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

Formats the value using the given formatter.

impl Error for DecodingOperationError

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<DecodingOperationError> for Error

fn from(source: DecodingOperationError) -> Self

Converts to this type from the input type.
