Member Function Documentation

getCameraMake()

cras::optional<std::string> movie_publisher::LibavStreamMetadataExtractor::getCameraMake ( )

overridevirtual

Returns

Camera manufacturer.

Reimplemented from movie_publisher::MetadataExtractor.

getCameraModel()

cras::optional<std::string> movie_publisher::LibavStreamMetadataExtractor::getCameraModel ( )

overridevirtual

Returns

The camera model name (just the model, without manufacturer).

Reimplemented from movie_publisher::MetadataExtractor.

getCreationTime()

cras::optional<ros::Time> movie_publisher::LibavStreamMetadataExtractor::getCreationTime ( )

overridevirtual

Returns

The global time corresponding to the first frame of the movie stream.

Reimplemented from movie_publisher::MetadataExtractor.

getGNSSPosition()

std::pair<cras::optional<sensor_msgs::NavSatFix>, cras::optional<gps_common::GPSFix> > movie_publisher::LibavStreamMetadataExtractor::getGNSSPosition ( )

overridevirtual

Returns

GNSS position of the camera when capturing the frame. Timestamps are zero.

Reimplemented from movie_publisher::MetadataExtractor.

getName()

std::string movie_publisher::LibavStreamMetadataExtractor::getName ( ) const

overridevirtual

Return the name of the extractor.

Returns

The name.

Implements movie_publisher::MetadataExtractor.

getPriority()

int movie_publisher::LibavStreamMetadataExtractor::getPriority ( ) const

overridevirtual

Return the priority of the extractor (for ordering in MetadataManager).

Returns

The priority. Lower values have more priority. Usually between 0 and 100.

Implements movie_publisher::MetadataExtractor.

getRotation()

cras::optional<int> movie_publisher::LibavStreamMetadataExtractor::getRotation ( )

overridevirtual

Returns

Rotation of the image in degrees. Only values 0, 90, 180 and 270 are supported.

Reimplemented from movie_publisher::MetadataExtractor.
