Hi,
I recently decided to upgrade from vdr 1.3.13 + an older xine plugin to 1.3.34 and xine plugin 0.7.6.
I'm using xine-lib 1.1.0 with the xine plugin.
Now I've compiled both the same xine-lib and vdr once for x86 and once for x86_64 (so I'm really using the same source) but only the version for x86_64 works.
If I strace the xine process running on my x86 machine I can see that it closes /tmp/vdr-xine/stream right after a few reads. This does not happen on the x86_64 one.
Would someone have any ideas as to why this might be happening? All pipes in /tmp/vdr-xine are present and have sane permissions. I'm using the same glibc versions and am using non nptl ones in both cases.
VDR is not patched in any way and I'm not using any CC flags besides the default ones.
Any help is appreciated.
kind regards Philip

The below strace extract doesn't contain a close(7).
Would someone have any ideas as to why this might be happening? All pipes in /tmp/vdr-xine are present and have sane permissions. I'm using the same glibc versions and am using non nptl ones in both cases.

I don't think that it has anything to do with opening the fifos, as they open properly just before the call to clone().
Are you sure that your xine-lib get's called in the x86 case and not an older version which lacks support for some of vdr-xine's remote procedure calls?
kind regards Philip
