Hello,
I've build a new VDR with h.264 xineliboutput plugin software decoding

buffer overruns and distorted recordings on all HD channels:

This occurs with both saa7146 and mantis pci tuner cards.
This has not occured with the old VDR system using Broadcomm's
crystalhd decoder in libxine.
You're talking about "xineliboutput" and "libxine", as well as
"saa7146", "mantis pci tuner cards"
and "Broadcomm's crystalhd decoder". Did you change several of these at
the same time?
? I didn't understand that fully.
Yes, the issue is reproducible with both tv card models and linux
3.12.40...6.x drivers.
No, the old crystalhd system is already deactivated and dissassembled
for selling to eastern europe.
Can you start from a working system and change only one at a time, to
find out which one
causes the problem.
Yes, the testing platform is the new DFI x86 I7 System with plenty of
ressources using xineliboutput ffmpeg AV software decoding.
Nov 7 18:13:21 vdr2 vdr: [25428] initializing plugin: xineliboutput
(2.0.0-cvs): X11/xine-lib Ausgabe-Plugin
I could install e.g. softhddevice to crosscheck if still available in
yavdr precision ppa but kaffeine recording works fine?
The issue occurs using production software vdr 2.0.6 AND
using recent VDR and drivers with minidvblinux.de 6.5 live system
(xineliboutput).
Both SD (MTV,ARD,ZDF, DELUXE MUSIC) and HD Channels (ARD,ZDF) affected.
I've already increased the libxine buffer:
Nov 8 01:33:22 vdr2 vdr: [6124] [input_vdr] Using non-default
"media.xvdr.num_buffers_hd:5000"
It looks like a problem with the high bandwidth ZDF/ARD channels,
like we had with the old TT/Siemens full-featured mpeg2 decoder dvb
cards but this should not occur with the advanced TDA10023 Tuner cards,
Recordings of the low bandwidth TELE5/DMF SD channels are always ok.
I've recorded TELE5 and DMF channels simultanously for 2h without any
buffer overflow in logs.

After some Minutes the buffers overflow and the record gets distorted.
LIVE TV works fine.
I've tried stable and testing minidvblinux.de VDR live systems to
crosscheck, but same issue occurs.
If I increase the buffer for the saa7164 cards with module parameter
it's getting worse and distorted picture and sound.
Any Ideas?
Increase VDR's buffer in source code?
Where's the (ring) buffer code in VDR sources, I try increasing?

What is the correct driver module debug parameter to provide a useful
debog log?
There're no buffer options in the mantis kernel driver.

Not a DVB drivers or hardware issue.
Good old Kaffeine DVB app recordings are OK, no distorted stream.
VDR BUG!
Can you send me a recording that shows the problem?
You can use https://www.transfernow.net to do so.
