I haven't tested it, and I was planning to ignore 4.0 until my next build. But looking at a system with an earlier 60.0 beta, $strings /usr/lib/firefox/libxul.so | grep libavc media.libavcodec.allow-obsolete Invalid FFMpeg libavcodec candidate Unusable LibAV's libavcodec 57 Invalid LibAV libavcodec candidate Obsolete FFMpeg libavcodec candidate Obsolete LibAV libavcodec candidate unsupported-libavcodec libavcodec-ffmpeg.so.57 Invalid libavcodec candidate libavcodec-ffmpeg.so.56 libavcodec.so.57 libavcodec.so.56 libavcodec.so.55 libavcodec.so.54 libavcodec.so.53 So I assume that if firefox is run from a term it might produce one of those messages (maybe others - I forget if more than libavcodec is partially-shipped in the firefox sources). Looking back, we had 56 in BLFS-7.9 (ffmpeg-2.8 series) and all of the various 3-series versions here had 57. This is very bad news. Thanks for the report, not sure how to fix it. ĸen -- This email was written using 100% recycled letters. -- http://lists.linuxfromscratch.org/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
