This is a bugreport for mplayer, or probably ffmjpeg. Mplayer cannot play the mjpeg avis correctly with ffmjpeg, that are created using lavrec with a Matrox Marvel G400-TV card. It starts playing, sound works, but only a blank window is showed. (The OSD works.) I can play the avis using the win32 dlls. Included files: mplayer -v -v log output: marvel-mjpeg-with-ffmpeg.log.gz sample avi: marvel-mjpeg-sample.avi System information Kernel version: Linux alom 2.4.7 #1 Tue Oct 16 16:48:14 CEST 2001 i686 unknown Libc version: /lib/libc-2.2.4.so X version: 4.1.0 GCC version: Reading specs from /usr/lib/gcc-lib/i386-linux/2.95.4/specs gcc version 2.95.4 20011006 (Debian prerelease) LD version: GNU ld version 2.11.92.0.12.3 20011121 Debian/GNU Linux Binutils version: GNU assembler 2.11.92.0.12.3 20011121 Debian/GNU Linux Copyright 2001 Free Software Foundation, Inc.
