Enum Error 

#[non_exhaustive]
pub enum Error {
    Ffmpeg(String),
    NoEncoder(String),
    NoCaptureBackend(&'static str),
    NoVideoStream(String),
    InvalidFramerate(u32),
    Codec(Error),
    Moq(Error),
    TimeOverflow(TimeOverflow),
}

Errors returned by moq-video.

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.

Ffmpeg(String)

libav* (capture, scaling, or codec) failure.

Carries the formatted message rather than the typed ffmpeg_next::Error on purpose: keeping ffmpeg out of the public surface means an ffmpeg-next major bump isn’t a breaking change for consumers.

NoEncoder(String)

No encoder matching the requested codec / hardware preference was compiled into the linked ffmpeg.

NoCaptureBackend(&'static str)

The requested input format (avfoundation / v4l2 / dshow) is not available in the linked libavdevice.

NoVideoStream(String)

The opened capture device exposed no decodable video stream.

InvalidFramerate(u32)

The configured framerate was zero (would divide by zero / produce a degenerate codec time base).

Codec(Error)

moq-mux codec/transport error (H.264 import, catalog).

Moq(Error)

moq-net transport error.

TimeOverflow(TimeOverflow)

Timestamp overflow converting to the moq microsecond timescale.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<TimeOverflow> for Error

fn from(source: TimeOverflow) -> Self

Converts to this type from the input type.
