Enum PacerError 

pub enum PacerError {
    InvalidTimeBase {
        numerator: i32,
        denominator: i32,
    },
    UnpaceableTimestamp {
        pts: i64,
    },
    NotAttached,
}

Errors specific to Pacer.

Variants

InvalidTimeBase

time_base came from crate::elements::FileDemuxer::stream_time_base/an encoder’s own time base — i.e. from a demuxed file or an otherwise externally supplied stream, not a value this crate controls. A malformed or unusual stream can legitimately have an invalid one.

Fields

numerator: i32

Invalid rational numerator.

denominator: i32

Invalid rational denominator.

UnpaceableTimestamp

pts is external input too (see PacerError::InvalidTimeBase) — an adversarial or corrupt value that cannot be turned into a wait at all: it does not fit in nanoseconds at this stream’s time base.

Reported rather than swallowed because the alternative is the buffer going through unpaced, which is a whole stream arriving at once.

Fields

pts: i64

The timestamp, in its own stream’s units.

NotAttached

A buffer arrived before the pipeline gave this pacer its playback clock, which cannot happen through ordinary wiring: attach_context runs when the branch is built and a branch cannot carry buffers before it exists.

Reported rather than passed through, because pacing nothing is a whole stream arriving at once and there is no quieter way for that to go wrong.

Trait Implementations

impl Debug for PacerError

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

Formats the value using the given formatter.

impl Display for PacerError

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

Formats the value using the given formatter.

impl Error for PacerError

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<PacerError> for Error

fn from(source: PacerError) -> Self

Converts to this type from the input type.
