Error PDAL: Unknown subpackage v3: 6 when reading a RIEGL rxp file

[philwilkes]

When some processing rxp files:

pdal info ../../ScanPos007.SCNPOS/scans/230526_060717.rxp

I get the error:

PDAL: Unknown subpackage v3: 6
Bus error (core dumped)

PDAL version 2.4.3

This is does not happen for all files. These can be imported into RiSCAN so don't think files are corrupt.

Happy to share rxp file if required.

A stack trace of a debug build would be more helpful.

Thanks @hobu, is this more helpful

Must be something inside the RXP library throwing an exception we're not capturing. I guess I would need the file to be able to fix it.

I understand you are probably very busy but that would be great! :)

You can download a file from here.

Is this an old file or a new file? I'm using the latest RivLib release. I assume we must need to ask scanlib if this particular packet type packed_shot_echos_sbl_hr is available

[philwilkes]

Data generated with a VZ400i, this instrument is ~12 months old.

For this project we ran the scanner at 600 khz i.e. >1 MTA zone, I have not noticed this issue for data generated at 300 khz before (1 MTA zone).

I can share more files from this same project e.g. that do and do not through this error.

ok. the RivLIB has a bunch of different packet types, and this file doesn't have the expected packet type. I dont know RivLIB well enough to fix this with a quick one. We are available for hire if you wanted to go that route, otherwise you're going to have to slug it out with RivLIB to make a pull request to overcome this.
