Enum VideoError

pub enum VideoError {
    Open {
        path: PathBuf,
        source: Error,

Video errors: enumeration, negotiation, streaming, scanout.

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.

Open

A device node would not open.

Fields

path: PathBuf

The node that failed.

source: Error

The underlying error.

NothingPlayable

No decoder on this board accepts any of the offered assets.

The menu is two codecs wide precisely so this stays unreachable on a Raspberry Pi — a kiosk that ships both files always has a playable one.

V4l2

An ioctl against the decoder failed.

Fields

what: &'static str

Which call.

source: Errno

The errno.

UnsupportedFormat(u32)

The decoder produced a frame format the plane path does not handle.

NoFrames

The stream never yielded a decodable picture.

Drm

A DRM call on the plane path failed.

Fields

what: &'static str

Which call.

source: Error

The underlying error.

NoPlane

No video plane on the CRTC supports the decoder’s output format.

Trait Implementations

impl Debug for VideoError

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

Formats the value using the given formatter.

impl Display for VideoError

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

Formats the value using the given formatter.

impl Error for VideoError

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.
