That's probably a bug in fe_api5_checkcap(). I've fixed it locally,
not sure if that patch is already in Flo's repo.
Basically, you cannot only query an adaptor's delivery system (DVB-S
vs. DVB-S2) before requesting a specific mode. That is because there
might be cards which can actually change their frontend (cut'n'pasted
from my fe.c):
#if (DVB_API_VERSION>=5)
static int fe_api5_checkcap(struct adapter_s *adapter) {
struct dtv_properties cmds;
struct dtv_property prop_set[2] = {
{ .cmd = DTV_CLEAR, },
{ .cmd = DTV_DELIVERY_SYSTEM, .u.data = adapter->type, },
};
struct dtv_property prop_get[1] = {
{ .cmd = DTV_DELIVERY_SYSTEM, .u.data = adapter->type, },
};
/* First try to set the adapter to the expected mode. Otherwise,
some cards may claim to utilize a different delivery system... */
cmds.props = prop_set;
cmds.num = ARRAY_SIZE(prop_set);
if (ioctl(adapter->fe.fd, FE_SET_PROPERTY, &cmds) < 0) {
logwrite(LOG_ERROR, "fe: ioctl FE_SET_PROPERTY failed (setting frontent type) - %s", strerror(errno));
}
/* Now request FE type. */
cmds.props = prop_get;
cmds.num = ARRAY_SIZE(prop_get);
if (ioctl(adapter->fe.fd, FE_GET_PROPERTY, &cmds)) {
logwrite(LOG_DEBUG, "fe: ioctl(FE_GET_PROPERTY) failed - no API 5 support?");
return 0;
}
logwrite(LOG_ERROR, "fe: Adapter %d is an adapter of type %d ", adapter->no, (int)prop_get[0].u.data);
