ROS1 MCAP reader in C++

[GianlucaCerilli]

Good afternoon,
I am using a working MCAP writer/reader in C++ for JSON-encoded messages.
Now I have to read a ROS1 bag converted to MCAP, but this mantains the ROS1-encoding after the conversion.

I would like to know if you have a script/example in C++ to either:

• convert the MCAP log file from ROS1 to JSON encoding
• read the ROS1-encoded MCAP log file

Thanks a lot
