HDMI and Composite capture on Lager, for kernel 4.1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



  This is our latest test branch for video support on Lager, ported
to kernel 4.1 as per commit 9cae84b32dd52768cf2fd2fcb214c3f570676c4b
("[media] DocBook/media: fix syntax error") on the media-tree master
branch last week.

  Single frame and video capture is working with appropriate test
cases for gstreamer, some (minor) quirks notwithstanding.
Functionally, this is in more or less the state we need it to be; for
the rest of the world we hope we have enhanced the ability to do any
necessary debugging on it. The intention is to upstream this version
as soon as possible, subject to feedback.

  NB: for single frame capture, images of appropriate resolutions are
created from both composite and HDMI inputs. For best quality video
capture we have found that gst-launch-1.0 needs a pipeline specifying
width, height, format ("=YUY2" in particular has an appropriate
turnaround time for smooth results), and framerate.
