[MPlayer-users] mplayer crash extracting audio from rawdv file

[Steven M. Schultz]

Greetings -

	I can extract the audio from a .mpg file using the command:

mplayer -v -vc dummy -vo null -ao pcm -aofile foo.wav capture005.mpg

	but when using a raw dv file (!form2 avi) with:

mplayer -v -vc dummy -vo null -ao pcm -aofile foo.wav capture005.dv
	
	I get a MPlayer crashed message.   Everything starts out fine, the
	"AO: Description: RAW PCM/WAVE file writer audio output" indicates
	that things are well under way and then the crash:

MPlayer interrupted by signal 11 in module: decode_audio 
- MPlayer crashed by bad usage of CPU/FPU/RAM. Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and disassembly. For details, see DOCS/bugreports.html section 5.b.
- MPlayer crashed. This shouldn't happen. It can be a bug in the MPlayer code _or_ in your drivers _or_ in your gcc version. If you think it's MPlayer's fault, please read DOCS/bugreports.html and follow instructions there. We can't and won't help unless you provide these informations when reporting a possible bug.
Uninit audio filters...

	What did I do wrong _this time_ :)
