USB Webcam driver (c) 2004-2008 François Revol. Parts (c) Be,Inc. (ProducerNode sample code). Current version of my USB Webcam driver. WORK IN PROGRESS! Uses the USB Kit (userland API, needs libusb) to publish a media node representing the webcam. It currently only works with my Sonix webcam (3Euro cheapo cam, using an SN9C120 chip), but is modular enough to easily expand it, some code is already there to detect Quickcams. Note however that most webcams only support isochronous transfers, so will NOT work in R5 or even Zeta as isochronous is mostly not working. That's the reason for only supporting my Sonix webcam as it is bulk capable. As soon as iso support is added to the USB stack and the USB Kit it should be possible to support other webcams quite easily. For now you should be able to build it under Zeta with the makefile provided. There are 3 kinds of device-specific folders : addons/ contains actual usb chip support code for each device. sensors/ contains code to handle CMOS sensors, as each model of a specific brand usually have a different CMOS chip despite a common usb chip. cstransforms/ for colorspace transforms so other device using the same weird colorspace can reuse the code (not yet used, sonix has its own code for now). It should be possible to use Translator-based transforms, making it easy to support webcams sending JPEG pictures. Another option is to turn all cstransforms into actual Translators usable by other apps, or also media codecs but that would be more work for few added value. Other notes and TODO: - finish the bayer cstransform and use that instead of copied (MIT) code in Sonix addon. - implement handling picture sizes correctly (currently forced in the ProducerNode and the Sonix code to 320x240) - there are currently 2 Deframer classes, the StreamingDeframer although more complex seems to work much better than the BufferingDeframer. Make my mind about them. - write isochronous code when USB Kit supports it - add quickcam support (I have some code around) (requires iso) - add code to support Fuji FinePix to merge the FinePix addon from bebits ? (need to find one to test) - design an extensible API to publish possible controls as ParameterWeb or forward ParameterWeb changes right to the device-specific addon and provide default handlers for usual controls ?
