Errors from running frames through a configured filtergraph. Variants carrying a FilterGraphError 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.

RequestOldestError(FilterGraphError)

Returned when requesting the next frame from the graph fails (avfilter_graph_request_oldest).

ProcessFramesError(FilterGraphError)

Returned when processing frames through the filtergraph fails.

SendFramesError(FilterGraphError)

Returned when sending frames into the filtergraph fails.

ChannelLayoutCopyError(FilterGraphError)

Returned when copying an audio channel layout while configuring the graph fails.

BufferSourceAddFrameError(FilterGraphError)

Returned when pushing a frame into a graph input fails (av_buffersrc_add_frame).

BufferSourceCloseError(FilterGraphError)

Returned when closing a graph input at end of stream fails (av_buffersrc_close).

BufferReplaceoseError(FilterGraphError)

Returned when replacing a frame’s buffer reference fails (av_buffer_replace).

FrameSideDataCloneError(FilterGraphError)

Returned when cloning frame side data for the graph fails.

ParseError(FilterGraphParseError)

Returned when parsing or configuring the filtergraph description fails.

InvalidData

Returned when a frame entering the graph carries invalid or corrupted data.

PreConfigQueueOverflow(String, usize, usize)

Returned before the graph is configured when one input has buffered frames past the admission limit while another input has not yet delivered its first frame; fields are the input label, the buffered frame count, and the estimated retained memory in bytes.

OversizedSideDataClone(String, usize)

Returned when a frame’s combined side-data metadata is too large to deep-copy into the buffersrc parameters; fields are the input label and the estimated size in bytes.

ThreadExited

Returned when spawning the filtergraph thread fails, so the graph never ran.

Trait Implementations

impl Debug for FilterGraphOperationError

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

Formats the value using the given formatter.

impl Display for FilterGraphOperationError

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

Formats the value using the given formatter.

impl Error for FilterGraphOperationError

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<FilterGraphOperationError> for Error

fn from(source: FilterGraphOperationError) -> Self

Converts to this type from the input type.
