75403 2004-12-22 21:44 0000 libtheora doesn't work with -O3 in mplayer and xine 2005-02-06 09:01:20 0000 1 1 1 Unclassified Gentoo Linux Ebuilds unspecified x86 Linux RESOLVED FIXED P2 normal --- 1 caneko@gmail.com media-video@gentoo.org caneko@gmail.com 2004-12-22 21:44:23 0000 Using optimization -O3 makes libtheora to doesn't work with neither MPlayer nor Xine, complaining about the theora header. Reproducible: Always Steps to Reproduce: 1. CFLAGS="-O3" emerge media-libs/libtheora 2. mplayer somevideo.ogg (with theora video codec) 3. xine somevideo.ogg Actual Results: The sound is played fine, but no video is displayed. MPlayer gives the following (sniped to interesting part): Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family Could not open codec. VDecoder init failed :( Opening video decoder: [theora] Theora/VP3 Broken Theora header; errorCode=-20! VDecoder init failed :( Cannot find codec matching selected -vo and video format 0xFFFC. Read DOCS/HTML/en/codecs.html! Xine fails with: libtheora: cannot decode stream without header Expected Results: Both players should play both files without problems. Changing the -O3 flag with -O2 solves the problem in both players. chriswhite@gentoo.org 2005-02-06 09:01:20 0000 Fixed in cvs, thanks for reporting:)
