Enum FilterGraphError 

#[non_exhaustive]
pub enum FilterGraphError {
    OutOfMemory,
    InvalidArgument,
    IOError,

}

FFmpeg-level errors during filtergraph processing, carried by FilterGraphOperationError.

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.

OutOfMemory

Memory allocation failed (AVERROR(ENOMEM)).

InvalidArgument

FFmpeg rejected an argument as invalid (AVERROR(EINVAL)).

IOError

A low-level I/O error occurred (AVERROR(EIO)).

PipeError

The stream or data connection was broken (AVERROR(EPIPE)).

BadFileDescriptor

An invalid file descriptor was used (AVERROR(EBADF)).

NotImplemented

The functionality is not supported by the linked FFmpeg build (AVERROR(ENOSYS)).

OperationNotPermitted

The operation was not permitted (AVERROR(EPERM)).

TryAgain

The graph is temporarily unable to accept or produce data (AVERROR(EAGAIN)).

EOF

The filtergraph reached end of stream (AVERROR_EOF).

UnknownError(i32)

Any other failure; the payload is the raw FFmpeg error code.

Trait Implementations

impl Debug for FilterGraphError

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

Formats the value using the given formatter.

impl Display for FilterGraphError

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

Formats the value using the given formatter.

impl Error for FilterGraphError

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<i32> for FilterGraphError

fn from(err_code: i32) -> Self

Converts to this type from the input type.
