Hi everybody,
This patch against wengophone-2.1 adds some aliases for the YUY2 pixel
format to the list of format codes that pixertool recognizes. It also
adds the UYVY conversions on the V4L side. With it, I was able to get
a YUYV webcam to supply video to wengophone on Linux.
It also seems important that the V4L webcam module support requesting
supported pixel formats from the driver. Otherwise, for drivers that
support multiple pixel formats, but were last configured to use a
format that wengophone does not support, capture will fail.
Thanks.
