Hello. Itīs me again... ;-) Last week I wrote, that I would like to create a pseudo-device "video" which handles the functionality which is provided by the videodev.* sources to linux. But after a while, I couldnīt realize the advantages from such a device. Because the device-driver behavior is a little bit different than that on linux, I donīt think, that we need such a pseudo device, if we code the hardware-driver itself in a video4linux compatible way. And the user sets the link from /dev/video to /dev/whatevervideodevice itself (or through the MAKEDEV script). The other thing is, if the system would use such a pseudo-device, everything that is read/written to/from the hardware-device passes the kernel for 2 times. Maybe Iīm totally wrong, or you can correct me in any way... What would you think about it? Thanks in advance. Joachim Jaeckel.
