Playback not working

[street-magic]

Any resolution for the playback of saved sonar data?
I have recorded 8-bit sonar data with liboculus and need to parse it. The version of liboculus from 3 years ago does not read correct data, any suggestions?
What is the problem with the playback, maybe I can help.

Thanks for the email. Our day-to-day use has transitioned to our ROS-based wrapper, so the non-ROS user tools have atrophied a bit. Let me look at the code and refresh my memory on the issue...

To follow up, I took a first crack at re-implementing this feature in the feature/fix_playback branch. Besides bugs introduced by underlying API changes, the major change was the underlying library changed to a callback-based API to userspace.

Unfortunately, the only sample data I have are the short snippets in the test/data/ directory, the flags in this data indicate that gains have been appended to the data, but there aren't enough bytes in the packet for this to be true, leading to a segfault. This might have to do with the age of the snippets ... may have been taken with firmware that predates the "sendGain" feature.

Medium term I should add a sanity check on packet size vs expected contents to avoid the segfault. Short term, please try the new version of oc_client and see if it parses your data.
