Errors from opening an input file, stream, device, or custom input source. Most variants are mapped from the FFmpeg error code returned by avformat_open_input.

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)).

NotFound

The file, URL, or device does not exist (AVERROR(ENOENT)).

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 or input format is not supported by the linked FFmpeg build (AVERROR(ENOSYS)).

OperationNotPermitted

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

InvalidData

The file or stream contains invalid or corrupted data (AVERROR_INVALIDDATA).

Timeout

The connection timed out (AVERROR(ETIMEDOUT)).

InvalidOption(String)

A builder option carried an invalid value (e.g. a non-positive set_framerate, a non-finite set_ts_scale, an out-of-range set_io_buffer_size). Setters store values as given and defer validation to open time, so a bad value surfaces here instead of panicking in the setter.

UnknownError(i32)

Any other failure; the payload is the raw FFmpeg error code (rendered with av_err2str in the message).

InvalidSource

Returned when the input has no usable source: neither a URL nor a custom read callback was configured.

InvalidFormat(String)

Returned when the explicitly requested input format name is unknown to FFmpeg; the payload is the requested name.

SeekFunctionMissing

Returned when the input requires seeking but the custom input source provides no seek callback.

Trait Implementations

impl Debug for OpenInputError

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

Formats the value using the given formatter.

impl Display for OpenInputError

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

Formats the value using the given formatter.

impl Error for OpenInputError

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<OpenInputError> for Error

fn from(source: OpenInputError) -> Self

Converts to this type from the input type.

impl From<i32> for OpenInputError

fn from(err_code: i32) -> Self

Converts to this type from the input type.
