How to extract data from an XCDR recorded file?

Hi,  

I was wondering if there's a way I can extract a sample (for example first and last sample) from an XCDR log file generated using the Recording Service?

I understand this can be done if I use the Converter service and convert my log file into JSON format. However I'm using rather large data, and the process of converting the whole log file will take significant time when I just need to extract a few samples from that file.

DynamicData to JSON/XML w/ Modern C++ API

Hi,

I'd like to serialize a DynamicData sample to JSON/XML using the Modern C++ APIs.

I realize there are internal APIs:  DDS_DynamicDataFormatter_to_xml and DDS_DynamicDataFormatter_to_json.  But, these APIs seem to take DDS_DynamicData types as arguments.  Is there an equivalent API for the Modern C++ DynamicData type ?  Thanks!
