After solving my device major/minor problem, I can play movies (A/V) on each H+ board. To create the device for thr 2sd board, use the minor 4,5,6,7 See the devices_1.sh script: ------------------------------------------------ #! /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 4 ln -fs /dev/em8300-49 /dev/em8300-1 mknod /dev/em8300_mv-1 c 121 5 ln -fs /dev/em8300_mv-49 /dev/em8300_mv-1 mknod /dev/em8300_ma-1 c 121 6 ln -fs /dev/em8300_ma-49 /dev/em8300_ma-1 mknod /dev/em8300_sp-1 c 121 7 ln -fs /dev/em8300_sp-49 /dev/em8300_sp-1 chmod 666 /dev/em8300* else echo "Hmmm, looks like you have devfs mounted, Im going to be safe and leave things alone!" fi ------------------------------------------------ For board 3 use minor: 8,9,10,11 and for 4th board use minor 12,13,14,15 (not tested by myself). There is a small bug in Mplayer (I am using: 0.90rc2-2.95.4), as it confuse the ASCII code and the device number. So, device 0 is seen as 48, and device 1 as 49, so when you access /dev/em8300-0, in fact Mplayer try /dev/em8300-48. Same for dev/em8300-1, Mplayer try /dev/em8300-49. For the moment, this bug can be bypassed using a link as you can see in the script (ln -fs /dev/em8300-49 /dev/em8300-1). Then setup devices and upload the microcode: # ./ldm and # ./em8300setup You should see 2 uploades. And play: $ mplayer -aid 2 -vo dxr3:prebuf:sync:norm=3:1 -ao oss:/dev/em8300_ma-1 ./film1.avi $ mplayer -aid 1 -vo dxr3:prebuf:sync:norm=3:0 -ao oss:/dev/em8300_ma-0 ./film0.avi On my AMD 1.2GHz, with 256Mo SDRAM, both movies are fluent (512x288) and picture on TV is perfect. If I try to play a 3th movie on my VGA and Sound Board, this 3th movie is jerky. I will try with 2 more boards, and keep you updated.
