Waibel (nikiwaibel) Assigned to: Nobody/Anonymous (nobody) Summary: xine-lib: bus error on sol8/sparc sol9/sparc Initial Comment: xine-lib reports a bus error on sol8/sparc, sol9/sparc but works fine on sol9/x86!!!, lnx/x86, lnx/x86_64. tested with and without medialib. the problem is i dont know how to debug this, because: === nwaibel@blade100-2 ~ $ gdb xine GNU gdb 6.0 Copyright 2003 Free Software Foundation, Inc.

(maybe medialib). ---------------------------------------------------------------------- Comment By: James Stembridge (jstembridge) Date: 2005-02-03 15:44 Message: Logged In: YES user_id=537148 Ok, to test that you can disable the cache by adding #nocache to the end of the MRL. For example: xine /home/download/kb3teaser.avi#nocache ---------------------------------------------------------------------- Comment By: Niki W.

But there are still several other posibilities to catch the bug: - try, if there are some formats, videooutputs, which are OK - search the "ugly" plugin: - audio?: xine MRL#noaudio - video?: xine MRL#novideo - cache?: xine MRL#nocache - demux?: xine MRL#demux:cdda (should be heard strange noise) (it expects CDDA demuxer works fine) - demux?, other test: xine MRL#demux:cdda\;save:file.dat (the file will be shorter to multiply of 2352) (it expects CDDA demuxer works fine) - and combinations: xine MRL#nocache\;demux:cdda\;novideo\;noaudio - and various input plugins - binary search the CVS version, which worked fine (but it might be hard work :-() Cheers, Frantisek ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=109655&aid=1115338&group_id=9655 |
