I suppose the following are bugs? Ubuntu 14.04.3 64 bit. When I run dvbv5-scan, I get a lock but then it times out with a Segmentation fault. So far I haven't found a solution for this. user@server2:~$ dvbv5-scan AMC21-125W0.dvbv5scan -l UNIVERSAL -F -o CHANNEL Using LNBf UNIVERSAL Europe 10800 to 11800 MHz and 11600 to 12700 MHz Dual LO, IF = lowband 9750 MHz, highband 10600 MHz ERROR command MODULATION (4) not found during store INFO Scanning frequency #1 11106000 Lock (0x1f) Signal= 70.50% C/N= 100.00% UCB= 65535 postBER= 67108864 Segmentation fault (core dumped) Referring to the above output, I don't know what is causing the Modulation error. Furthermore, I'm unable to use 8PSK for modulation even though the docs on the spec says it's a valid modulation option. The following test file was used for the above: (and I had to modify the FREQUENCY because dvbv5-scan -l? doesn't give a LNBF with a 10750 LO freq) ki7rw@server2:~$ cat AMC21-125W0.dvbv5scan [MONTANA_PBS] DELIVERY_SYSTEM = DVBS2 FREQUENCY = 11106000 POLARIZATION = VERTICAL SYMBOL_RATE = 2398000 INNER_FEC = AUTO MODULATION = QPSK INVERSION = OFF -- 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
