Greetings I'm trying to convert an ASF file to an MP3. I was positive mencoder had the ability to accomplish this, as mplayer can play the file. So to encode to MP3, I tried this command: mencoder -o lenny.mp3 -oac mp3lame -v lenny_kravitz_WeWantPeace.asf Turns out this command is COMPLETELY WRONG. The correct way to do this is: mplayer -ao pcm -aofile audio.wav lenny_kravitz_WeWantPeace.asf oggenc -o lenny.ogg audio.wav OK, fine, my bad. However, mencoder segfaults, which isn't pretty. Here's the segfault output: MEncoder 0.90rc5-3.3 (C) 2000-2003 Arpad Gereoffy (see DOCS) CPU: Advanced Micro Devices Athlon 4 PM Palomino/Athlon MP Multiprocessor/Athlon XP eXtreme Performance (Family: 6, Stepping: 2) Detected cache-line size is 64 bytes CPUflags: Type: 6 MMX: 1 MMX2: 1 3DNow: 1 3DNow2: 1 SSE: 1 SSE2: 0 Reading /home/saan/.mplayer/codecs.conf: can't open '/home/saan/.mplayer/codecs.conf': No such file or directory Reading /usr/share/mplayer/codecs.conf: 50 audio & 136 video codecs File not found: 'frameno.avi' Reading config file /home/saan/.mplayer/mencoder: No such file or directory init_freetype Using MMX (with tiny bit MMX2) Optimized OnScreenDisplay Not an URL!

I wonder if this is a gentoo bug or if it should instead be reported to the mencoder authors.
Greetings, In response to whether it should be reported to the mencoder authors--I really don
Greetings, In response to whether it should be reported to the mencoder authors--I really don´t know. I was under the impression that I should report the bug here, and if it´s a bug that should be reported to mencoder, the gentoo mplayer maintainer would handle it. I can´t remember where I got this impression, so perhaps I made it up... Thanks Ben
Voltron, your impression is correct
