Errors that can occur during video decoding operations.

Variants

EndOfFile

End of video stream reached (not necessarily an error).

FileReadError

Failed to open or read the input file.

Fields

cause: String

The underlying cause of the error.

GenericDecodeError

Catch-all for decoding problems not covered by other variants.

Fields

cause: String

The underlying cause of the error.

NoVideoStream

No decodeable video stream found in the input file.

NoDecoder

No suitable decoder available; consider enabling ffmpeg or vapoursynth.

UnsupportedDecoder

The active decoder backend does not support the called function.

VariableFormat

Variable-format streams are not supported.

VariableResolution

Variable-resolution streams are not supported.

VariableFramerate

Variable-framerate streams are not supported.

UnsupportedChromaSubsampling

Unsupported chroma subsampling (x, y are horizontal/vertical factors).

Fields

x: usize

Horizontal chroma subsampling factor.

y: usize

Vertical chroma subsampling factor.

UnsupportedFormat

Unsupported pixel format or codec.

Fields

fmt: String

The format identifier that triggered the error.

Trait Implementations

impl Clone for DecoderError

fn clone(&self) -> DecoderError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DecoderError

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

Formats the value using the given formatter.

impl Display for DecoderError

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

Formats the value using the given formatter.

impl Error for DecoderError

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.
