Re: vdr htpc + xine = dropped frames warning

[Jiri Dobry <jdobry@xxxxxxxxxx>]

Hello,

Dropped frames with xine/xineliboutput + vdr is real problem.
And suppress warning messages is not solution. Dropped frames is visible. Sometimes less, sometime more.

This steps little help:
Option "TripleBuffer" "true"  in xorg.conf in Screen section

In xine configuration file:
video.processing.ffmpeg_pp_quality:0
video.processing.ffmpeg_skip_loop_filter:all
engine.decoder_priorities.vdpau_h264:1
engine.decoder_priorities.vdpau_mpeg12:1
engine.decoder_priorities.vdpau_mpeg12:1

Disable VSYNC synchronization will reduce CPU usage dramaticaly to 0-8% on mpeg2/h264, with small effect to dropped frames:
xvattr -a XV_SYNC_TO_VBLANK -v 0

If you have AMD/integrated graphic, force minimum frequency for scaller to 1.8Ghz, it have bandwidth problem:
echo 1800000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

During 4 month I was try everything. Over 20 different version of xinelib, over 20 version of ffmpeg, 4 different computers. Nothing was 100% solution.

I was try to create thread on nvnews server, but sometime I thing tha I am alone who is able too see this problem. (http://www.nvnews.net/vbulletin/showthread.php?p=2134207)

I am running a htpc with vdr 1.7.11 + xine

I was using oxine where there is no problem with warnings but unfortunately it does not support vdpau and doesn't seem to be regularly maintained.

I have disabled dropped frames warning in xine but somehow I still get from time to time a window telling me that xine is dropping some frames.
Since the HTPC is not connected to a mouse the only work around is to press the power button on the remote (which is mapped to a script that kills xine and returns to the main menu)

I would appreciate if somebody could point me to a sure way to get rid of all warnings in xine, in fact I do not want xine to display anything other than the vdr osd and the ts stream.
Is easy to patch the xine source code to act more suitably to an htpc?
    

Make sure you are _not_ running xine when you edit ~/.xine/config, and
make sure you edit the correct one.  Meaning if you start xine as
root, login as root and edit the config file.  If you start it as a
user, login with that user name and edit, etc.....

The correct setting would be:
gui.dropped_frames_warning:0
