I think our last missing major feature is now SXGA. My progress is this:
1. The attached patch enabled me to make mplayer _request_ SXGA. Some I2C messages are SOI968 specific (enabling SXGA in the sensor).
2. The attached image is the output I get from mplayer. As you can see the NOKIA brand on my mobile is visible but most of the image is missing.
Ideas? GWater
