At some point it is necessary; however, you should avoid doing format conversions in the kernel. But if you don't do it, no application will understand the format. My recommendation: in the short term, write format conversions into the kernel driver so that applications work using the standard V4L(2) api. Invent also new format description, so that userspace applications can get the raw the if they understand it. In the longer term, prepare to stream the raw data into userspace, and write an userspace module to do the format conversion. A Gstreamer module would be nice, then every application would benefit from it when they are all converted to use gstreamer :-> -- | Tuukka Toivonen <tuukkat@xxxxxxxxxx> [OpenPGP public key | Homepage: http://www.ee.oulu.fi/~tuukkat/ available] | M.Sc.
