📝 WalkthroughWalkthroughThis change adds protobuf deserialization and file persistence for multiple datatypes. It extends replay support, updates Python bindings, adds normalized geometry fields, exposes node aliases, and adds serialization and replay tests. ChangesProtobuf serialization and replay
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This PR adds persistent save/load and replay support for serialized messages, but metadata-only loads can overwrite existing payload data, incomplete image metadata can reach unsafe transformation deserialization, and protobuf-disabled configurations may fail on the new test target. These concrete correctness, runtime, and build risks should be fixed before merge. Sequence Diagram(s)sequenceDiagram

Pull request overview
This PR extends DepthAI’s protobuf-backed message types by adding on-disk persistence (save/load) to ProtoSerializable and by expanding deserialization support so additional message types can participate in record/replay workflows. It also introduces clearer alias names for the existing Record/Replay “metadata-only” host nodes.
Changes:
- Add
ProtoSerializable::save()/ProtoSerializable::load()for writing and reading serialized message payloads to/from disk. - Implement protobuf deserialization for previously unsupported message types (e.g.,
ImgDetections,SpatialImgDetections,SegmentationMask,RGBDData, etc.) and update replay logic accordingly. - Add new/updated tests covering proto save/load roundtrips and RGBD MCAP replay, plus Python bindings for
ProtoSerializableand node aliases.

In `@bindings/python/src/pipeline/datatype/ProtoSerializableBindings.cpp`:
- Line 8: Add the standard DOC(dai, ...) documentation argument to the
py::class_ declaration for ProtoSerializable, matching the existing
documentation pattern used by neighboring pybind11 class bindings.
- Around line 23-26: Update the ProtoSerializable binding registration so save
and load remain available even when DEPTHAI_ENABLE_PROTOBUF is disabled. Add
stub implementations for ProtoSerializable::save and ProtoSerializable::load in
that configuration that raise a clear RuntimeError, while preserving the
existing functional bindings when protobuf is enabled.
In `@include/depthai/pipeline/datatype/ADatatype.hpp`:
- Line 24: Update the inheritance declarations for both ADatatype and
ProtoSerializable to use public ADatatypeInterface inheritance. Preserve the
existing shared interface relationship so external upcasts work consistently and
mixed types such as EncodedFrame do not retain separate interface subobjects.
In `@include/depthai/utility/ProtoSerializable.hpp`:
- Around line 48-53: Remove the nonexistent metadataOnly Doxygen parameter
documentation from the load method declaration in ProtoSerializable, leaving
documentation only for the path argument and preserving the existing load(const
std::filesystem::path&) API.
- Around line 46-53: The save/load serialization flow in ProtoSerializable must
preserve the datatype header even when the protobuf payload is empty. Update
save() and its implementation to always write the header independently of bytes
length, and update load() to validate that header before accepting an empty
payload, while retaining normal payload handling for non-empty data.
In `@src/utility/ProtoSerializable.cpp`:
- Around line 23-67: Update writeMsgBinaryFile to always write the DatatypeEnum
header, including when bytes is empty, and validate the write result
independently of payload size. Update readMsgBinaryFile to always read and
validate the header after confirming the file contains it, then read payload
bytes only when the buffer is non-empty so empty payloads round-trip correctly.

Timestamp: 2026-03-23T09:35:30.339Z
Learning: In luxonis/depthai-core’s `protos/common.proto`, do not change existing enumerator values for the public `LengthUnit` and `CameraBoardSocket` enums, and do not prepend new zero-value entries like `UNSPECIFIED`. These enums are already released as public API and are used in serialized data; altering numeric values or changing the first/zero member will break backward compatibility with existing user code and stored/serialized representations.

Learning: Do not flag the `!= ""` part of the auto-calibration condition as redundant when it appears in `PipelineImpl::build()` (or closely related pipeline build logic). If the code uses `utility::getEnvAs<std::string>(..., default)` with a default such as `"ON_START"`, the explicit empty-string guard may still be intentional to treat an explicitly empty env var as “OFF/disabled” (or to avoid special-casing elsewhere). Only consider removing `!= ""` if the codebase has an explicit, enforceable guarantee that `DEPTHAI_AUTOCALIBRATION` can never be set to an empty string (e.g., via validated parsing/CI checks); otherwise, keep the guard.

I've been thinking about the file suffixes. If we used extensions like |
|
@JakubFara the datatype is saved in the file and validated when read. IMO this is the better option since renaming the file doesn't corrupt it. |

Another small suggestion: It would be nicer to do or even than |

Note GitHub couldn't provide a complete incremental comparison for this pull request, so CodeRabbit is performing a full review instead. This review may take a little longer. |

- Around line 81-133: Give serializePoint2f, deserializePoint2f,
serializeSize2f, deserializeSize2f, serializeSpatialRect, and
deserializeSpatialRect internal linkage by placing them in the existing
anonymous namespace pattern used by the later helpers; if any must be called
from another translation unit, instead declare it in ProtoSerialize.hpp.
- Around line 1546-1550: Update setProtoMessage(ImgFrame&, ...) to delegate to
populateImgFrameFromProto instead of duplicating the field mapping. Move the
has_ts() and has_tsdevice() presence checks into populateImgFrameFromProto
first, preserving their current behavior, then remove the duplicated mapping and
metadataOnly payload handling from setProtoMessage.
- Around line 615-681: Guard both transformation assignments in the frame
deserialization paths: update the callers around populateImgFrameFromProto and
the corresponding encFrame population to check has_transformation() before
calling deserializeImgTransformation, matching the existing guards in other
deserializers. Also harden deserializeImgTransformation itself by validating
that the transformation matrix contains the required three rows and columns
before indexing arrays(i), preventing malformed input from causing an
out-of-range access.
In `@src/utility/ProtoSerialize.hpp`:
- Around line 78-91: Update the DEPTHAI_PROTO_DECLARE definition in
ProtoSerialize.hpp to use an unconditional define so collisions with an existing
definition are diagnosed, and move its `#undef` immediately after the final
declaration (RGBDData), before the namespace closing braces.

successfully.
- Around line 722-724: Wrap the proto_serializable_test dai_add_test and
dai_set_test_labels commands in an if(DEPTHAI_ENABLE_PROTOBUF) condition, so the
test target is only registered when protobuf support is enabled.
- Line 908: Update the replay_test target_include_directories configuration to
remove ${PROJECT_SOURCE_DIR}/include/depthai while retaining
${PROJECT_SOURCE_DIR}/src; rely on the depthai::core target for generated
Protobuf headers.
In `@tests/src/onhost_tests/replay_test.cpp`:
- Around line 124-158: Extend the ReplayMetadataOnly test around replayNode, q,
and the RGBDData assertions to produce a non-zero replay offset: record at least
two messages or enable looping and read beyond the recorded data. Validate the
third replayed RGBDData message, confirming its RGB and depth child sequence
numbers and timestamps are shifted by the same delta as the parent while
preserving the existing metadata and payload checks.
- Around line 87-88: Replace TestHelper in the replay test with a test-local
directory from dai::platform::getTempPath(), then construct replayPath beneath
it. Add RAII cleanup for the temporary directory so it is removed on both
success and failure, without invoking filenamesInArchive or depending on the
extracted recording.

Learning: Do not flag the `!= ""` part of the auto-calibration condition as redundant when it appears in `PipelineImpl::build()` (or closely related pipeline build logic). If the code uses `utility::getEnvAs<std::string>(..., default)` with a default such as `"ON_START"`, the explicit empty-string guard may still be intentional to treat an explicitly empty env var as “OFF/disabled” (or to avoid special-casing elsewhere). Only consider removing `!= ""` if the codebase has an explicit, enforceable guarantee that `DEPTHAI_AUTOCALIBRATION` can never be set to an empty string (e.g., via validated parsing/CI checks); otherwise, keep the guard.

These enums are already released as public API and are used in serialized data; altering numeric values or changing the first/zero member will break backward compatibility with existing user code and stored/serialized representations.

So the reason for the new ADatatypeInterface was so that you could call getDatatype() and to then set it in the file header?
All the serializable messages override serializeSchema() which has schemaName = descriptor()->full_name(); (eg dai.proto.img_frame.ImgFrame) and thats what is used for mcap. We could also use it here to skip the reinterpret cast.
One additional thing: using enumerator as the file header is unstable because it can change when adding new message types, we could replace it with a protobuf message like:
syntax = "proto3";
package dai.proto.message_file;
message MessageFile {
string type_name = 1; // descriptor full_name of the payload
bool metadata_only = 2;
bytes payload = 3; // output of serializeProto()
}
Then save and load functions would look like:
void ProtoSerializable::save(const std::filesystem::path& path, bool metadataOnly) const {
proto::message_file::MessageFile file;
file.set_type_name(serializeSchema().schemaName);
file.set_metadata_only(metadataOnly);
const auto bytes = serializeProto(metadataOnly);
file.set_payload(bytes.data(), bytes.size());
...
}
void ProtoSerializable::load(const std::filesystem::path& path) {
std::ifstream in(resolveDataPath(path), std::ios::binary);
proto::message_file::MessageFile file;
if(!in || !file.ParseFromIstream(&in)) throw std::runtime_error("Failed to read " + path.string());
const auto expected = serializeSchema().schemaName;
if(file.type_name() != expected)
throw std::runtime_error("File " + path.string() + " contains " + file.type_name() + ", expected " + expected);
deserializeProto({file.payload().begin(), file.payload().end()}, file.metadata_only());
}
We can then get rid of the ADatatypeInterface + you load would know if it is metadata_only + mcap, foxglove and the save function would rely on the same full_name() descriptor + we can add a generic load buffer function that reads a file and at runtime figures out the datatype

Propagate metadata_only during loading.
Line 69 discards message.metadata_only(). The deserialization helpers therefore use their default metadataOnly == false path for every saved file. A metadata-only load can then execute payload-loading branches and replace data in a reused destination.
Add a metadata-only argument to ProtoSerializable::deserializeProto and utility::deserializeProtoMessage. Pass message.metadata_only() from Line 69 through to setProtoMessage. Add a test that loads a metadata-only file into an object with existing payload data.

getProtoSchema runs serializeFdSet on every call, and save /load calls it just to read schemaName. We could cache returnPair as a function-local static const SchemaPair, so it is built once on first use and only copied afterwards
