Moikka!
I did some testing and I cannot see reason to force hw pid filter for
that device. I assume you somehow think it does not work without
filtering, but I think it does.
I tested streaming with mn88472 demod DVB-C and DVB-T2 modes without
stream errors. DVB-T2 (live) datarate 45Mbps and DVB-C (modulator)
datarate 50Mbps. Maximum DVB-T2 (8MHz) datarate is 50Mbps - in a real
life it is bit less.
DVB-C
1fff 19870.47 p/s 29184.8 Kbps 207966 KB
TOT 34313.26 p/s 50397.6 Kbps 359127 KB
DVB-T2
1fff 2589.99 p/s 3804.0 Kbps 21400 KB
TOT 30346.18 p/s 44570.9 Kbps 250745 KB
So point me the reason hw PID filters need to be forced.
regards
Antti
