HLCI support for VDR

[Anssi Kolehmainen]

Hi,

I was wondering are there any plans to add HLCI (High-level CI) support to
VDR. Currently it only supports LLCI (Link-level CI) and therefore is unusable
with my FireDTV card.

I tried MythTV and it has implemented both HLCI and LLCI. It works just fine
so it might be somewhat easy to cut'n'paste the code (at least if you know
what the whole CI thing does).

[Actually the mythtv dvbci.cpp has copyright notice on top claiming it to be
from vdr :) ]

Firedtv stops working after a while

[Anssi Kolehmainen]

Hi,

I have Firedtv DVB-C/CI adapter and for some reason it stops working
after a while. Typically it takes something like 5 hours (which makes
debugging fun).  I have vdr 1.7.9 as the dvb viewer (with xine plugin),
kernel 2.6.31 x86_64, latest v4l-dvb drivers from hg and the few
remaining patches from firesat.kurelid.se.

Vdr spews following to syslog [1]:
Nov  4 03:00:42 maxwell vdr: [26241] frontend 0 timed out while tuning to 
channel 400, tp 266
Nov  4 03:13:35 maxwell vdr: [26242] ERROR: can't set filter (pid=18, tid=40,

Nov  4 03:13:53 maxwell vdr: [26242] ERROR: can't set filter (pid=3306, tid=02, 
mask=FF): Device or resource busy

whereas kernel says [2]:
3[548957.448338] firedtv 0012870036002e6f-0: FCP response timed out
3[548957.448343] firedtv 0012870036002e6f-0: can't set PIDs
4[548974.380505] DVB (dvb_dmxdev_filter_start): could not alloc feed
4[548974.380864] DVB (dvb_dmxdev_filter_start): could not alloc feed
 + lots of fancy FCP communication debugging thanks to firedtv debug=-1

Kernel-time 548975 corresponds with real time 03:13:35. Computer
start was at 1256748240. I had to log kernel messages to separate file
so it wouldn't eat all space with syslog files.

Trivial workaround is to rmmod firedtv + modprobe firedtv but it is
rather annoying.  The freeze might be connected to vdr doing EPG scan
and trying to check all channels but manually triggering that scan
doesn't cause any malfunctions.

Any ideas what I should try?

[PATCH] support for channel numbers in scan with Finnish DVB-C Welho

[Anssi Kolehmainen]

Hi,

Attached is small patch to enable channel numbering for FI DVB-C Welho
(similar to UK Freeview). Works for me though resulting list needs to be
sorted before using or else VDR gets channel numbers wrong.
