And according to old usb sniffs from pctv 292e [Si2168B] default
manual ts clock is set to 7.2MHz, which means 57.6Mbit/s datarate,
it should be quite optimal for DVB-T2 max. In theory it could be a
little higher only when 10MHz channel bandwidth and most less error
correction FEC in use. And currently driver is using some config
that uses dynamic ts clock which clocks only when there is data to
feed. For some reason, usb-ts-bridge does not understand that and
manual configuration is needed (ts valid or ts-sync connection?).
If possible use 7.2MHz, if not: set to 10MHz.
That's perfectly alright with me. I'm now testing that 7.2Mhz value.
Hold on.
The driver crashes with the 7.2Mhz value! That was totally not what I
ever expected.
Recompiled the whole kernel: crashes again. Then tried on debian
kernel 4.19: same thing.
Food for thought?
It should sure never crash the kernel. Changing a ts bitrate no, no,
no, you trapped a hidden bug. Found where it is :]
Ah, maybe I did unplug it while it was live. I;ll check again tommorrow.
