you mean /boot/beos/system/boot/Bootscript ? I changed the line exec > /dev/null 2>&1 to exec > /dev/dprintf 2>&1 , am I supposed to see messages in the terminal now? Because I don't see anything. In order to have the media_addon loaded, it has to placed under /boot/beos/system/add-ons/media right? Apparently the only media add ons that gets loaded is the mixer, while the usb_webcam is not longer loaded even if it's there. Since it used to get loaded, before I started coding it, I need to know why it doesn't get loaded anymore, and for that I need its, or the media_server, debug info. :) Is there any documentation about media addons development or something close?
