Hello!
I have 3 Femto cameras and I need to retrieve RAW stream from IR and Depth sensors.
I’m using C++ api.
Code sample:
auto profiles = pipeline.getStreamProfileList(type);
std::shared_ptr<ob::VideoStreamProfile> profile = nullptr;
if (profiles) {
try {
profile = profiles->getVideoStreamProfile(640, 480, ((type == 2) ? OB_FORMAT_RGB : OB_FORMAT_Y16), 10);
}
catch (ob::Error& e) {
std::cerr << type<<" function:" << e.getName() << "\nargs:" << e.getArgs() << "\nmessage:" << e.getMessage() << "\ntype:" << e.getExceptionType() << " "<<OB_EXCEPTION_TYPE_INVALID_VALUE << std::endl;
profile = std::const_pointer_cast<ob::StreamProfile>(profiles->getProfile(0))->as<ob::VideoStreamProfile>();
}
}
config->enableStream(profile);
Where type is IR and Depth.
During running pipeline I’m receiving this error:

And I’m receiving only IR stream.
I can switch configuration and receive only Depth stream.
But sometimes I can have both streams!
Could you please help me
