I solved it by modifying the Makefile in the /usr/src/xine-lib-1.2/src/audio_dec directory.

Help building xine-lib-1.2 --with-external-ffmpeg
by Stefan Ellenberger 01 Oct '08

Thanks Niels, indeed this helped me as well. Now I'm getting a HUGE amount of "undefined reference to av_log" It starts browsing the ffmpeg source tree (where I built ffmpeg) for libav c files here's the one that makes it quit: /usr/local/lib/libpostproc.a(postprocess.o): In function `pp_get_mode_by_name_and_quality': /usr/src/ffmpeg_12.09.2008_test/libpostproc/postprocess.c:758: undefined reference to `av_log' /usr/src/ffmpeg_12.09.2008_test/libpostproc/postprocess.c:776: undefined reference to `av_log' /usr/src/ffmpeg_12.09.2008_test/libpostproc/postprocess.c:787: undefined reference to `av_log' /usr/src/ffmpeg_12.09.2008_test/libpostproc/postprocess.c:899: undefined reference to `av_log' /usr/src/ffmpeg_12.09.2008_test/libpostproc/postprocess.c:901: undefined reference to `av_log' /usr/local/lib/libpostproc.a(postprocess.o):/usr/src/ffmpeg_12.09.2008_test/libpostproc/postprocess.c:1067: more undefined references to `av_log' follow collect2: ld returned 1 exit status make[3]: *** [xineplug_decode_ff.la] Fehler 1 make[3]: Verlasse Verzeichnis '/usr/src/xine-lib-1.2/src/combined/ffmpeg' make[2]: *** [all-recursive] Fehler 1 make[2]: Verlasse Verzeichnis '/usr/src/xine-lib-1.2/src/combined' make[1]: *** [all-recursive] Fehler 1 make[1]: Verlasse Verzeichnis '/usr/src/xine-lib-1.2/src' make: *** [all-recursive] Fehler 1 You happen to know a way around this as well? Since you are using XUbuntu like I do you might have experienced the same problem. I don't hope it is getting any worse than that... 1. how many fixes in the code have been necessary until you (Niels) could run a save compile? 2. Could anyone point out what kind of developer libraries you installed in order to compile xine-lib savely? I just added the minimum - meaning apt build dependencies for ffmpeg and xine-lib - this also covers all of the libs listed in the sidux wiki (http://www.vdr-wiki.de/wiki/index.php/Sidux_VDR_DVB-S2#xine-lib) > I did. Just edit /usr/src/xine-lib-1.2/src/audio_dec/Makefile. Look for > -ldts_pic and add -lm after it.

Or the stable 1.1.x releases? You might want to try the 1.1.x releases instead. SVN is bleeding edge and can sometimes result in ackward unstability. Anyway. Perhaps an optimized build of ffmpeg and xine-lib. Also, I can't really tell if a P4 3.0Ghz is fast enough. A DualCore is adviced for viewing HDTV. In both cases. You might want to experiment with the CoreAVC dshowserver plugin for Xine (link was posted a few days ago). While you have a single-core CPU, CoreAVC is much more faster then FFMpeg. In my case, my Core2Duo didn't go above the 100% resulting in dropouts of frames and audio in combination with FFMpeg. Now I'm testing with the CoreAVC dshowserver plugin for Xine, and I can now see my cores being used and the image (and Xine!) producte stable results. BTW, CoreAVC is an Windows plugin. But you can use it in combination with the dshowserver patch/enhancement. CoreAVC is not free though, it costs around 10,- ($15,-) but in imho, worth the money. Regards, Niels Wagenaar

High cpu usage with vdr-xine
by serge pecher 01 Oct '08

Hello, I made an installation follwing <a href="http://www.vdr-wiki.de/wiki/index.php/OpenSUSE_VDR_DVB-S2_-_xine">http://www.vdr-wiki.de/wiki/index.php/OpenSUSE_VDR_DVB-S2_-_xine</a>. I am using Ubuntu 8.04 + a S2-3200 on a P4 3 Ghz, 1GB ram When I play SD channels I have a cpu usage of +/- 20-30% When I try Simul HD I can see the CPU usage slowly going up to +/- 95 %, after what xine crashes I start Xine with the line given in the wiki. What tunning can I do ? thanks, sp
