playDataset can't read calibration file

[alejandronespereira]

There seems to be a bug with the camera calibration reader in which no float is correctly read. Here's my output, using the sequence 45

I added those lines for debugging purposes. Seems like
std::sscanf(l1.c_str(),"%f %f %f %f %f", &inputCalibration[0], &inputCalibration[1], &inputCalibration[2], &inputCalibration[3], &inputCalibration[4]);
at FOVundistorter.cpp isn't parsing the calibration file correctly. I've tried with other sequences to no avail.

Looks like the same issue as #13 maybe? Have you seen my comments in #13 (comment)? What is your locale setting?

Could you try adding something like

std::setlocale(LC_ALL, "C");

to the start of your program. I don't really know how to properly set locale for scanf. You might need to do a quick google search to find the right call.

Yes it seems to be a similar issue. I'll look into it and tell you how it goes, thanks!

[alejandronespereira]

Yep. Works like a charm, thanks!
