Enum EncodeError 

pub enum EncodeError {
    Spawn {
        source: Error,
        path: String,
    },
    Io(Error),
    PipelineFailed {
        exit: Option<i32>,
        stderr: String,
    },
    Unsupported {
        format: OutputFormat,
        os: &'static str,
        reason: &'static str,
    },
    InvalidConfig(String),
}

Failure modes for the encoder.

Variants

Spawn

gst-launch-1.0 could not be spawned (missing from PATH).

Fields

source: Error

OS-level reason.

path: String

$PATH snapshot at failure.

Io(Error)

I/O failure on the scratch / output file.

PipelineFailed

gst-launch-1.0 exited non-zero. stderr carries GStreamer’s own diagnostic for the user / log.

Fields

exit: Option<i32>

Exit status of the gst-launch child.

stderr: String

Captured stderr.

Unsupported

Format / OS combo not yet implemented (e.g. Linux real encoders pending). The trait still constructs cleanly so callers can verify configuration; runtime invocation surfaces this error.

Fields

format: OutputFormat

Format that was requested.

os: &'static str

OS name (target_os value).

reason: &'static str

Human-readable reason / pointer to follow-up ticket.

InvalidConfig(String)

Validated config rejected (e.g. width=0, framerate=0).

Trait Implementations

impl Debug for EncodeError

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

Formats the value using the given formatter.

impl Display for EncodeError

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

Formats the value using the given formatter.

impl Error for EncodeError

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<Error> for EncodeError

fn from(source: Error) -> Self

Converts to this type from the input type.
