What is the output of
lsof | grep frontend
when VDR is in the "idle" state?
I produced some output from /proc/$(pgrep vdr)/fd which I think might be
more helpful. The last-but-one "ls" output was "too soon" after I
started and paused the recording, so VDR was still in normal mode.
In case you wonder, the connection between lircd and vdr did not work
last time I tried, and probably also not this time. That is why I used
telnet to the SVDRP port.
The last "ls" command was when VDR was expected to be idle (after
1-minute timeout, instead of the 15-minute timeout of your patch). I ran
the command once more after a while, and the output remained identical.
Note that this USB DVB-T stick has two frontends for the same aerial
connector. I think that one is for DVB-T and another for DVB-T2. You can
see that "frontend1" was replaced with "frontend0" in the not-quite-idle
mode.
I am happy to try a revised patch, and I can also use GDB ("thread apply
all backtrace" and such) if that is needed.
This was the latest commit 0d50ec57f50375c8fda92d117e348dd8fd5a77a9
("Version 2.5.6") from http://git.tvdr.de/vdr.git with only your patch
on top (and the 15-minute timeout changed to 1 minute).
Best regards,
Marko
