I was trying out this library and I found two things that probably need fixing in dvb_fe_retrieve_quality. Without this it only returns DVB_QUAL_UNKNOWN for my setup. Issue 1 on line 1205: ber = dvb_fe_retrieve_per(&parms->p, layer); As far as I can tell this should use dvb_fe_retrieve_ber (so _ber instead of _per) with the appropriate arguments. Issue 2 on line 1218: dvbv_fe_cnr_to_quality(parms, cnr); This probably needs to be changed to the following because it doesn't have any effect otherwise ;) qual = dvbv_fe_cnr_to_quality(parms, cnr); -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
