Expand description
When writing a match expression against ColorSpaceConversion
, 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 colorspaceconversion = unimplemented!();
match colorspaceconversion {
ColorSpaceConversion::Force601 => { /* ... */ },
ColorSpaceConversion::Force709 => { /* ... */ },
ColorSpaceConversion::ForceHdr10 => { /* ... */ },
ColorSpaceConversion::ForceHlg2020 => { /* ... */ },
ColorSpaceConversion::ForceP3D65Hdr => { /* ... */ },
ColorSpaceConversion::ForceP3D65Sdr => { /* ... */ },
ColorSpaceConversion::ForceP3Dci => { /* ... */ },
ColorSpaceConversion::None => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when colorspaceconversion
represents
NewFeature
, the execution path will lead to the second last match arm,
even though the enum does not contain a variant ColorSpaceConversion::NewFeature
in the current version of SDK. The reason is that the variable other
,
created by the @
operator, is bound to
ColorSpaceConversion::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 ColorSpaceConversion::NewFeature
is defined.
Specifically, when colorspaceconversion
represents NewFeature
,
the execution path will hit the second last match arm as before by virtue of
calling as_str
on ColorSpaceConversion::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. Specify the color space you want for this output. The service supports conversion between HDR formats, between SDR formats, from SDR to HDR, and from HDR to SDR. SDR to HDR conversion doesn’t upgrade the dynamic range. The converted video has an HDR format, but visually appears the same as an unconverted output. HDR to SDR conversion uses tone mapping to approximate the outcome of manually regrading from HDR to SDR. When you specify an output color space, MediaConvert uses the following color space metadata, which includes color primaries, transfer characteristics, and matrix coefficients:
- HDR 10: BT.2020, PQ, BT.2020 non-constant
- HLG 2020: BT.2020, HLG, BT.2020 non-constant
- P3DCI (Theater): DCIP3, SMPTE 428M, BT.709
- P3D65 (SDR): Display P3, sRGB, BT.709
- P3D65 (HDR): Display P3, PQ, BT.709
