I am trying to use 2 Dxr3 board on a single PC, but I am able to play only 1 DivX A/V stream with Mplayer. Here what I did: 1 - Module creation: I created a file: devices_1.sh (a copy of devices.sh with some modification): ------------------------------------------------ #! /bin/sh # This is a simple scripts to create the devices for em8300 driver, # it should abort if you have the devfs filesystem mounted, em8300 # supports devfs so there should be no need. DEVFS=`cat /proc/mounts | grep " devfs "` if [ -z "$DEVFS" ] ; then echo "Devfs not mounted creating device nodes" mknod /dev/em8300-1 c 121 0 ln -fs /dev/em8300-1 /dev/em8300 mknod /dev/em8300_mv-1 c 121 1 ln -fs /dev/em8300_mv-1 /dev/em8300_mv mknod /dev/em8300_ma-1 c 121 2 ln -fs /dev/em8300_ma-1 /dev/em8300_ma mknod /dev/em8300_sp-1 c 121 3 ln -fs /dev/em8300_sp-1 /dev/em8300_sp chmod 666 /dev/em8300* else echo "Hmmm, looks like you have devfs mounted, Im going to be safe and leave things alone!" fi ------------------------------------------------ And, I type "make devices" (of cource inthe makefile, I have the following line: @sh devices_1.sh ). And I got: # ll /dev/em8300* lrwxrwxrwx 1 root root 13 Feb 9 12:26 /dev/em8300 ->/dev/em8300-1 crw-rw-rw- 1 root root 121, 0 Dec 26 12:17 /dev/em8300-0 crw-rw-rw- 1 root root 121, 0 Feb 9 12:26 /dev/em8300-1 lrwxrwxrwx 1 root root 16 Feb 9 12:26 /dev/em8300_ma -> /dev/em8300_ma-1 crw-rw-rw- 1 root root 121, 2 Dec 26 12:17 /dev/em8300_ma-0 crw-rw-rw- 1 root root 121, 2 Feb 9 12:26 /dev/em8300_ma-1 lrwxrwxrwx 1 root root 16 Feb 9 12:26 /dev/em8300_mv -> /dev/em8300_mv-1 crw-rw-rw- 1 root root 121, 1 Dec 26 12:17 /dev/em8300_mv-0 crw-rw-rw- 1 root root 121, 1 Feb 9 12:26 /dev/em8300_mv-1 lrwxrwxrwx 1 root root 16 Feb 9 12:26 /dev/em8300_sp -> /dev/em8300_sp-1 crw-rw-rw- 1 root root 121, 3 Dec 26 12:17 /dev/em8300_sp-0 crw-rw-rw- 1 root root 121, 3 Feb 9 12:26 /dev/em8300_sp-1 2 - Modules initialisation: # ./ldm and # ./em8300setup Microcode uploaded to /dev/em8300-0 Current settings are: Video Aspect Audio Spu PAL 4:3 ANALOG ON Microcode uploaded to /dev/em8300-1 Current settings are: Video Aspect Audio Spu PAL 4:3 ANALOG ON 3 - Play the movies: I use the following command to play the movies: $ mplayer -aid 2 -vo dxr3:prebuf:sync:norm=3:1 -ao oss:/dev/em8300_ma-1 ./film1.avi and $ mplayer -aid 1 -vo dxr3:prebuf:sync:norm=3:0 -ao oss:/dev/em8300_ma-0 ./film0.avi When playing film1, the play is OK (Video + Audio), but I can't start film0, I got an error: $ mplayer -aid 1 -vo dxr3:prebuf:sync:norm=3:0 -ao oss:/dev/em8300_ma-0 ./film0.avi Using GNU internationalization Original domain: messages Original dirname: /usr/share/locale Current domain: mplayer Current dirname: /usr/local/share/locale MPlayer 0.90rc2-2.95.4 (C) 2000-2002 Arpad Gereoffy (see DOCS) CPU: Advanced Micro Devices Athlon TB Thunderbird (Family: 6, Stepping: 2) CPUflags: MMX: 1 MMX2: 1 3DNow: 1 3DNow2: 1 SSE: 0 SSE2: 0 Compiled for x86 CPU with extensions: MMX MMX2 3DNow 3DNowEx Reading /usr/local/etc/mplayer/codecs.conf: 49 audio & 125 video codecs Font /home/etienne/.mplayer/font/font.desc loaded successfully!
