[media] mem2mem_testdev: improve field handling

2014-03-11T13:34:56Z

try_fmt should just set field to NONE and not return an error if a different field was passed. buf_prepare should check if the field passed in from userspace has a supported field value. At the moment only NONE is supported and ANY is mapped to NONE. Signed-off-by: Hans Verkuil Signed-off-by: Kamil Debski Signed-off-by: Mauro Carvalho Chehab

[media] mem2mem_testdev: pick default format with try_fmt

2014-03-11T13:30:08Z

This resolves an issue raised by v4l2-compliance: if the given format does not exist, then pick a default format. While there is an exception regarding this for TV capture drivers, this m2m driver should do the right thing.

[media] mem2mem_testdev: use 40ms default transfer time

2014-03-11T13:29:38Z

The default of 1 second is a bit painful, switch to a 25 Hz framerate. Signed-off-by: Hans Verkuil Signed-off-by: Kamil Debski Signed-off-by: Mauro Carvalho Chehab

[media] v4l: Copy timestamp source flags to destination on m2m devices

2014-03-05T19:47:15Z

Copy the flags containing the timestamp source from source buffer flags to the destination buffer flags on memory-to-memory devices. This is analogous to copying the timestamp field from source to destination. Signed-off-by: Sakari Ailus Acked-by: Kamil Debski Signed-off-by: Mauro Carvalho Chehab
