Hi,
I'm working on a driver for a usb camera that outputs an mjpeg stream.
For various reasons, this needs to be v4l, not v4l2. But v4l provides
no real support for compressed streams. For now I've kludged an
application that uses libjpeg to decode the stream, but this breaks the
v4l api (as far as I can tell). What are people's thoughts on this
problem? I think my choices are to either provide a kernel module that
does the decoding, or continue using a user level codec, but having to
provide an "enhanced" viewer. I'm not enthralled with the idea of a
kernel codec. This driver will eventually be used in an embedded 2.4
kernel, as well as for normal webcam type cameras for desktop linux.
Any thoughts on what direction to go in? Thanks,
Steve
