I think %a in my esyslog call isn't correct, but it is used this way
with the sscanf call and when I changed it with %s I don't see any log
entry.
So how should the esyslog call look like ?
%a to print a char* is not right. char* is interpreted as double (see the
compiler warning) . If you want to print the pointer 'description', then
use %p.
The following code crashes on my box too. I dont know why.

[vdr] vdr 1.7.23: patch for handling symlinks in recordings directory as earlier
Hi, I am attaching a patch for vdr 1.7.23 for the problem described here: http://www.vdr-portal.de/board1-news/board2-vdr-news/p1047199-announce-vdr-developer-version-1-7-23/#post1047199 There appears to be a problem in listing recordings due to a bug fix in vdr 1.7.23. Fixed handling symbolic links in cRecordings::ScanVideoDir() The attached patch just disables the translation of symbolic links to real paths. So that all recordings appear to be under the same (recordings) directory tree, as it was earlier. Please reply with your results. -- Thanks, Sundararaj diff --git a/recording.c b/recording.c index cf35bb7..5772dab 100644 --- a/recording.c +++ b/recording.c @@ -1120,9 +1120,13 @@ void cRecordings::ScanVideoDir(const char *DirName, bool Foreground, int LinkLev continue; } Link = 1; +#if 0 + // do not resolve the symbolic links in paths to real path + // thereby keeping all the recordings under one directory buffer = ReadLink(buffer); if (!*buffer) continue; +#endif if (stat(buffer, st) != 0) continue; } ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
[vdr] strcmp() segfaults if one (and only one) of the parameters is NULL ?
Hi,
strcmp() returns 0 if both are parameters NULL, but segfaults if one
of the parameters is NULL.
Is this a known behaviour ? man page says nothing about NULL parameters.
I ask because, vdr checks for NULL parameter(s) to strcmp() sometimes.
Check for one or both parameters:
epg.c:692: if (shortText strcmp(title, shortText) == 0) {
epg.c:742: if (shortText description strcmp(shortText,
description) == 0) {
No check for null parameter:
channels.c:227: bool nn = strcmp(name, Name) != 0;
channels.c:228: bool ns = strcmp(shortName, ShortName) != 0;

Thanks,
Sundararaj

Re: [vdr] reelchannelscan for S2API-patched VDR
It seems to work fine with DVB-S. But it doesn't work with DVB-S2. I have took a look at transponders files of reel. And found that files hasn't any information about modulation (QPSK, 8PSK) I don't know how Reel don't use this informations for tuning. Transponder list does not provide information about modulation. Channelscan does not know about the modulation it simply tries one modulation after another in this order No modulation Set(for manual scan)/QPSK/8PSK/QPSK_S2.

I'm using vdr-1.7.0, multiproto_plus and the reelchannelscan plugin is from

I am not sure if reelchannelscan works with multiproto.

[vdr] cChannels::ReNumber() maxNumber
Hi all, if I empty channels.conf while VDR is running then cChannels::ReNumber() doesnot set cChannels::maxNumber to 0. Is this a feature ? Of course, when vdr is restarted I have maxNumber set to 0, thanks to initialization in cChannels(). Could we not, in the beginning of ReNumber(), set maxNumber = 0 ? I am running 1.4.7, 1.5.16 seems to be the same. Thanks. -- Sundararaj ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
Re: [vdr] trouble changing Setup variables from Plugin.
I change a VDR's setup setting from inside a plugin like: ::Setup.UseSmallFont = 0; ::Setup.Save(); // commit the change to setup.conf This is done only when the plugin's setting is changed. ( in the Store() ). When changes are accepted with OK, the setup.conf is written but it is immediately overwritten by a Setup.Save() call from cMenuSetupBase::Store(). How can I avoid this ? Is there a more orderly way to modify VDR's setup settings ? Why do you need to change VDR's setup settings? That's VDR's own business ;-) :) True. The skin plugin I am trying has its parameters buried deep inside submenus. I want the font setting of the skin displayed under the OSD-Expertmenu. And would like to change it when ever the skin's settings are changed - since they are related. -- Sundararaj ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

[vdr] VDR EPG documenation
Hi, I am novice in VDR programming. I tried writing a plugin for getting EPG data from the Internet and using it. Now a prototype is up and running. To debug, extend and maintain the plugin I could use some more information. I wish I could get my hands on some documentation on the VDR classes (what they do...) and EPG ( for eg. how/when to set eventID, TableID ). I have with me doxygen generated documentation. But I still do not have something on par with cEvent::FixEpgBugs() kind of comments. Any help would be welcomed.
