Support for Dual System USB Sticks
0%
Description
There are devices on the market like Astrometa DVB-C/T/T2 stick or PCTV 292e, which do support DVB-C and DVB-T. Always all frontends appear as DVB-T although one of them should be DVB-C. By now I have found two dirty workarounds to make DVB-C work on them (at least on Astrometa, OOB staging driver).
I can either delete frontend0 (DVB-T) and link frontend1 to it (so /dev/adapterX/frontend0 is equal to /dev/adapterX/frontend1) or
adapt the source in linuxdvb_adapter.c --> linuxdvb_adapter_add and fake the adapter to be of type DVB_TYPE_C instead of DVB_TYPE_T
As PCTV-292e drivers are not from staging and included since kernel 3.16, I expect them to at least behave correctly :-), quality of Astrometa is known to be poor, but the root cause seems to be the same (and with workaround seem to work fine for me). Is there a way to implement this correctly?

The tvheadend should probe all frontends and all delivery systems. The additional frontends should be added in this loop:

well the dvb-c frontend is detected, but as dvb-t. As I said if I link frontend1 as frontend0 it is detected as dvb-c, but when there is frontend0 which is dvb-t it will get recogniced as dvb-t. It can for sure be a driver issue, if you want me to log something let me know.

You should see 2 tuners - DVB-T and DVB-C not only one... Could you put some diff --git a/src/input/mpegts/linuxdvb/linuxdvb_adapter.c b/src/input/mpegts/linuxdvb/linuxdvb_adapter.c
Could you show me what is printed with this debug code?

I do see both frontends / tuner, but they both show up as DVB-T. So adapter4 is the device in question. Showing up in tvh as:
/dev/dvb/adapter4/[Realtek RTL2832 (DVB-T)]- Panasonic MN88473 : DVB-T #1 (which should be DVB-C) and
- Realtek RTL2832 (DVB-T) : DVB-T #0
here are the debug messages:

Sorry, it's a bit unreadable. I thought you have only one adapter, could you replace printf with tvhinfo to have all lines in order ?

OK, adapter4 only reports two DVB-T frontends here. The mn88473 driver should report all three subsystems:
.delsys = {SYS_DVBT, SYS_DVBT2, SYS_DVBC_ANNEX_AC},
I added new line to debug prints to see more:

Could you try the attached patch ? I think that I found the culprit.
Updated by B C about 10 years ago
looking good now, mn88473 is detected as DVB-C #1 and DVB-T #1, beside Realtek beeing DVB-T #0. I can select a DVB-C Network now. For other tests I will have to wait till the evening as its buggy driver once again faild to upload the firmware, so I will have to physically reattach it as unbinding just resulted in a kernel error
I will update ASAP
As alway, thank you for your great support here.

and voila, tuning is working as well, so this seems to be fixed, great, thanks

You don't have proper linuxdvb kernel headers. Use Linux DVB API 5.5 or later.
