In @src/prft.rs:
- Around line 18-50: ReferenceTime is missing serde derives causing Prft (which
derives Serialize/Deserialize under the serde feature) to fail; add conditional
serde derives to the ReferenceTime enum using cfg_attr(feature = "serde",
derive(serde::Serialize, serde::Deserialize)) so the enum is
serializable/deserializable when the serde feature is enabled, keeping its
existing Debug/Clone/PartialEq/Eq/Default derives intact; update the
ReferenceTime definition (the enum symbol ReferenceTime) to include this
cfg_attr so the build succeeds with the serde feature.

src/prft.rs (4)
6-16: LGTM!The
ext!macro invocation correctly defines the PRFT extension with version support (V0/V1) and the appropriate flag bits matching the ISO/IEC 14496-12 specification.
66-98: LGTM!The decoding logic correctly handles:
- Field order (reference_track_id, ntp_timestamp, then version-dependent media_time)
- Flag precedence for
utc_time_semanticsderivation- V0/V1 version selection for 32-bit vs 64-bit
media_time
100-133: LGTM!The encoding logic correctly:
- Maps
ReferenceTimevariants to the appropriate flag combinations- Auto-selects V0/V1 based on whether
media_timefits in au32- Maintains symmetry with the decode path
136-213: LGTM!The test suite provides good coverage:
- V1 decode/encode with conformance data
- V0 round-trip at the boundary (
u32::MAX)RealTimesemantics with combined flagssrc/lib.rs (1)
155-155: LGTM!The module declaration and public re-export follow the existing crate conventions. Based on learnings, this correctly integrates the new PRFT atom type into the crate's public API.
Also applies to: 174-174
src/any.rs (1)
332-332: LGTM!The
Prftvariant is correctly registered in theAnyenum's basic list, enabling flexible decoding. As per coding guidelines, new atom types should be registered in theAnyenum insrc/any.rs.src/test/h264.rs (1)
653-666: LGTM!The test correctly validates the new
Prftdecoding path with concrete field assertions, replacing the previousUnknownvariant handling. This confirms the end-to-end integration of the PRFT box implementation.
