#[non_exhaustive]pub enum AudioDurationCorrection {
Auto,
Disabled,
Frame,
Track,
Unknown(UnknownVariantValue),
}
Expand description
When writing a match expression against AudioDurationCorrection
, it is important to ensure
your code is forward-compatible. That is, if a match arm handles a case for a
feature that is supported by the service but has not been represented as an enum
variant in a current version of SDK, your code should continue to work when you
upgrade SDK to a future version in which the enum does include a variant for that
feature.
Here is an example of how you can make a match expression forward-compatible:
# let audiodurationcorrection = unimplemented!();
match audiodurationcorrection {
AudioDurationCorrection::Auto => { /* ... */ },
AudioDurationCorrection::Disabled => { /* ... */ },
AudioDurationCorrection::Frame => { /* ... */ },
AudioDurationCorrection::Track => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when audiodurationcorrection
represents
NewFeature
, the execution path will lead to the second last match arm,
even though the enum does not contain a variant AudioDurationCorrection::NewFeature
in the current version of SDK. The reason is that the variable other
,
created by the @
operator, is bound to
AudioDurationCorrection::Unknown(UnknownVariantValue("NewFeature".to_owned()))
and calling as_str
on it yields "NewFeature"
.
This match expression is forward-compatible when executed with a newer
version of SDK where the variant AudioDurationCorrection::NewFeature
is defined.
Specifically, when audiodurationcorrection
represents NewFeature
,
the execution path will hit the second last match arm as before by virtue of
calling as_str
on AudioDurationCorrection::NewFeature
also yielding "NewFeature"
.
Explicitly matching on the Unknown
variant should
be avoided for two reasons:
- The inner data
UnknownVariantValue
is opaque, and no further information can be extracted. - It might inadvertently shadow other intended match arms. Apply audio timing corrections to help synchronize audio and video in your output. To apply timing corrections, your input must meet the following requirements: * Container: MP4, or MOV, with an accurate time-to-sample (STTS) table. * Audio track: AAC. Choose from the following audio timing correction settings: * Disabled (Default): Apply no correction. * Auto: Recommended for most inputs. MediaConvert analyzes the audio timing in your input and determines which correction setting to use, if needed. * Track: Adjust the duration of each audio frame by a constant amount to align the audio track length with STTS duration. Track-level correction does not affect pitch, and is recommended for tonal audio content such as music. * Frame: Adjust the duration of each audio frame by a variable amount to align audio frames with STTS timestamps. No corrections are made to already-aligned frames. Frame-level correction may affect the pitch of corrected frames, and is recommended for atonal audio content such as speech or percussion.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Auto
Disabled
Frame
Track
Unknown(UnknownVariantValue)
Unknown
. See the docs on this enum for the correct way to handle unknown variants.Unknown
contains new variants that have been added since this code was generated.
