2015-03-18 Thread Chris Whittenburg
We're working on a DM3730 platform running a 3.5.7 kernel, using the pipeline below to take a 12-bit monochrome sensor (Aptina AR0130) and convert it to UYVY format for use with the TI codecs. In general, this works, but the images end up looking washed out. Running them thru a "normalize" functio

I'm using oe-core to build the 3.0.7+ kernel, which runs fine on my beagleboard-xm. I'm interested in the media controller framework, which I believe is in this kernel. I expected there to be a /dev/media0, but it is not there. I do see "Linux media interface: v0.10" in my dmesg log, so I know m
