class MultiFrameSetSource : public ouster::sdk::core::FrameSetSource

MultiFrameSetSource, combines multiple frame set sources into a single one.

Public Functions

MultiFrameSetSource(std::vector<std::shared_ptr<FrameSetSource>> sources)

Construct a MultiFrameSetSource from a provided sources.

Parameters:

sources[in] the sources to combine

virtual FrameSetIterator begin() const override

Provides each frame from all sensors in time order.

Returns:

start iterator for all sensors

virtual FrameSetIterator begin(int idx) const override

Provides frames from a single sensor in time order If idx < 0 provides frames from all sensors.

Parameters:

  • sensor_index[in] sensor index

  • sensor_index[in] sensor index

Throws:

std::runtime_error – if sensor_idx >= number of sensors

Returns:

start iterator for the sensor with the given index

virtual FrameSetIterator end() const override

Return the end iterator.

Returns:

end iterator

virtual const std::vector<std::shared_ptr<SensorInfo>> &sensor_info() const override

Get the sensor info for each sensor in this dataset.

Returns:

sensor info for each sensor

virtual bool is_live() const override

Indicates if the source is streaming from a device, such as a sensor.

Returns:

if live or not

virtual bool is_indexed() const override

Indicates if the source contains an index for fast random access.

Returns:

if indexed or not

virtual size_t size() const override

The length of the source from begin to end.

For example: If uncollated this is the total number of frames in the source, if collated this is the number of frame collations.

Throws:

std::runtime_error – if unindexed

Returns:

length of the source

virtual size_t size_hint() const override

The approximate length of the source if unindexed, or the real size if indexed.

Live sources or sources with undefined length will return 0.

Returns:

approximate length of source

virtual const std::vector<std::vector<std::pair<uint64_t, uint64_t>>> &individual_index() const override

timestamp based index of all frames in the file for each sensor, each pair is timestamp followed by global frame index

Throws:

std::runtime_error – if unindexed

Returns:

index

virtual const std::vector<std::pair<uint64_t, uint64_t>> &full_index() const override

timestamp based index of all frames in the file, each pair is timestamp followed by sensor index

Throws:

std::runtime_error – if unindexed

Returns:

index

virtual const std::vector<size_t> &frames_num() const override

Get the frame count for each sensor in the file.

Throws:

std::runtime_error – if unindexed

Returns:

frame count for each sensor in the file

virtual std::unique_ptr<FrameSetSource> move() override

move into a newly allocated item

Returns:

a unique pointer to a newly allocated FrameSetSource instance containing the moved-from state.
