Shown below is the ffmpeg version I'm running. I have two questions about different issues: 1) performance tuning and 2) using --enable-shared. --------------------------------------------------------------------------- reid at linux:~/FFMpeg-20050519/FFMpeg-20050519> ffmpeg -version ffmpeg version 0.4.9-pre1, build 4755, Copyright (c) 2000-2004 Fabrice Bellard configuration: --prefix=/usr --enable-mp3lame --enable-gpl built on May 18 2005 22:26:04, gcc: 3.3.4 (pre 3.3.5 20040809) ffmpeg 0.4.9-pre1 libavcodec 4755 libavformat 4624 ---------------------------------------------------------------------------- 1) Regarding performance tuning, I wonder if I well get better performance from ffmpeg if I ./configure it with the cpu info I'm using? I have an AMD x86_64. Should I use the --tune option, and would the syntax be --tune=x86_64, or some other syntax. What might that be, please? 2) When I have run ./configure with --enable-shared the Make bombs. Should I be adding some other options or switches (meaning..is it something I'm doing wrong?) and can you tell me what it is I need to do or is ffmpeg just not ready for --enable-shared with x86_64?
