Here is a bunch of fixes for gspca and a couple of fixes for

Hello,
I'm trying to get video using v4l2 ioctls from a gspca_ov519 camera, and after
STREAMOFF all buffers are still flagged as QUEUED, and QBUF fails. DQBUF also
fails (blocking for a 3 sec timeout), after streamoff. So I'm stuck, after
STREAMOFF, unable to get pictures coming in again. (Linux

I'm glad that we were able to add support for additional devices, but
this device is not in fact the Hauppauge Woodbury that it claims to
be -- I think it would be a better idea to copy the
AU0828_BOARD_HAUPPAUGE_WOODBURY configuration into a new structure,
rename it to something more appropriate,

Hi,
I think I discovered an interesting issue with dma_buf.

Hi,
This bug also causes the camera to crash when changing fps in
guvcview, uvc devices (at least all the ones I tested) require the
stream to be restarted for fps to change, so in the case of this
driver after STREAMOFF the camera just becomes unresponsive.

Those patches add end of stream handling for s5p-mfc encoder.
The first patch was sent already to the list as RFC, but the discussion ended
without any decision.
This patch adds new v4l2_buffer flag V4L2_BUF_FLAG_EOS. Below short
description of this change.
s5p_mfc is a mem-to-mem MPEG/H263/H264
Some devices requires indicator if the buffer is the last one in the stream.
Applications and drivers can use this flag in such case.

s5p-mfc encoder after receiving buffer with flag V4L2_BUF_FLAG_EOS
will put all buffers cached in device into capture queue.
It will indicate end of encoded stream by providing empty buffer.

More flexible and extensible syntax for format which allows better usage
of the selection API.
Continue supporting the old syntax but remove the documentation for it. It
was not supported in an official release and its use is thus deprecated.
