Hello
First: i'am note sure if this is the correct place to post "errors" regarding the PVR branch and especially to the VDR-XBMC interop. I someone has some advice, it would be helpfull
so now to the problem: I have a VDR-VNSI-XBMC setup.
VDR 1.7.16 - ftp://ftp.tvdr.de/vdr/Developer/vdr-1.7.16.tar.bz2
ExtensionPatch - http://copperhead.htpc-forum.de/download...es.diff.gz
VSNI - Plugin: https://github.com/opdenkamp/xbmc/tree/m...s/vdr-vnsi
XBMC 10.0 PVR-Build (PPA - https://launchpad.net/~lars-opdenkamp/+archive/xbmc-pvr)
While watching TV the performance is perfect for the most of the channels only some channels make problems. It's reproducible the same channels (for example ARD HD, Anixe HD, SIXX SD). Sometimes now sound-stream is avaible, sometimes the picture is is extremly fragmented. sometimes its played extremly slow. sixx SD has permanently the problem, that 1/3 of the picture-frames seems to be dropped. The sound is played well and synchron to the picture-steam.
The interesting thing is: If i use VDR with libxineoutput (testinstall yavdr 0.3.0) all channels perform perfectly if i switch to vnsi playback within yavdr the same problem appears again. If i switch to tvheadend the playback within xbmc is also perfect. it seemes ther is a problem with the combo vdr-vnsi-xbmc and this specific channels. But i don't know how to debug
i stay in contact with the vendor of my tv-card (sundtek) they analyse the raw-transponder-stream and notice that sixx(sd)/anixe hd(1080i) lying next together, they assume that could make problems.
Noticeable is, that the CPU Usage for VDR jumps up (from nearly 0 to somthing below 30%) if i tune in into the problematic channels. Additionaly it seems the error-message "VNSI-Error: DTS discontinuity." appears more frequently in the syslog.
Hardware info:
vdr backend: Atom330, 1Gbit lan. (only capturing the signal and delivering it via vnsi)
xbmc-frontend: Core2Duo 3Ghz per Core, 8800Gts VDPAU eneabled (displaying the VNSI signal)
both machines are remotely available for debugging purpose and if needed i'am able tho hack some code. But currently i don't even know to look were to start debugging.
