V4L/DVB: Add a new ERROR flag for DQBUF after recoverable streaming errors

2010-05-19T15:58:37+00:00

This flag is intended to indicate streaming errors, which might have
resulted in corrupted video data in the buffer, but the buffer can still
be reused and streaming may continue.

Setting this flag and returning 0 is different from returning EIO. The
latter should now indicate more serious (unrecoverable) errors.

This patch also solves a problem with the ioctl handling code in
vl42-ioctl.c, which does not copy buffer identification data back to the
userspace when EIO is returned, so there is no way for applications
to discover on which buffer the operation failed in such cases.

V4L/DVB: videodev2.h: move definition of enum v4l2_ctrl_type to the other control types

2010-05-19T15:57:06+00:00

For some reason the definition of enum v4l2_ctrl_type is far from the
place where it is actually needed. This makes it hard to work with this
header.

Move it to just before struct v4l2_queryctrl, which is the one that
actually uses it.

V4L/DVB: videodev2: introduce a common control for chroma gain

2010-05-18T03:50:16+00:00

Introduce a new control for modifying the chroma gain.  This allows for user
intervention in abnormal signal conditions cases where the decoder's chroma
AGC cannot compensate and the value needs to be adjusted manually.
