tv_grab_file not found

Added by M. Bergmann about 7 years ago

Hello,

until now I have been using a Synology NAS running TV Headend, but now I want to change to an own-built NAS which runs Debian 8.9 and Openmediavault 3.
I installed successfully TVHeadend 4.2-stable on the new NAS as well as the grabbers provided by https://sourceforge.net/projects/xmltv/, so nearly a dozen grabbers are shown as internal grabber modules.

Additionally I want to include a local xmltv-file, provided by WebGrab Plus. Therefore I use the tv-grab-file from https://github.com/Rigolo/tv-grab-file, changed the path to my xmltv-file, created a symlink to /usr/bin/tv-grab-file and made it executable. But within TvH it is not shown in the internal grabber modules.
All permissions are set to 777, the original tv-grab-file as well as the softlink and the xmltv-file, even all involved directories. Owner is always 'root'.

So why does it not show up in Configuration | Channel / EPG | EPG Grabber page ? Especially because all other tv_grab_* files are detected ?
(I also restarted the machine several times)

It seems to work when I am not using symlinks, but place the tv_grab_file directly into /usr/bin.
At least it appears in TvH.

I created the symlinks by the following commands:

ln -s /mystuff/xmltv/tv_grab_file /usr/bin/tv_grab_file
chmod +x /usr/bin/tv_grab_file

So I don't understand what went wrong?

EDIT: Tried to run the local grabber and TvH complained about missing permissions. Here I have to correct myself: The directories haven't had the 'executable' attribut, just the files. Now it seems to work.

The reason the symlinked version doesn't work is probably because of permissions issues of the link target. If your script is located in a directory that the user Tvheadend runs as cannot read, then it will not be able to execute the script. As far as populating the list of internal grabbers, I believe Tvheadend merely addds every {,/usr}/{,s}bin/tv_grab_* file it finds.
