What is the status of merging your development with v4l-utils? Version 1.16.5 doesn't provide --get/set-routing options. Also in the master of v4l-utils I haven't found your code. What is the current way of changing routing the video switches (e.g. xilinx-axis-swtich which is not yet in the mainstream kernel)?

The header update patches need to be reworked but the media-ctl + libv4l2subdev patches probably rebase just fine. -- Regards, Sakari Ailus ^ permalink raw reply [flat|nested] 4+ messages in thread

I've recently rebased the latest version of the patches (exclusing the changes to the Renesas drivers) that was posted to the linux-media mailing list, and have pushed the result to git://linuxtv.org/pinchartl/media.git muxed-streams This has only been compile-tested so far, and I hope to test it on real hardware soon. -- Regards, Laurent Pinchart ^ permalink raw reply [flat|nested] 4+ messages in thread

I have patched linux-xlnx [1] kernel and media-xlnx [2] such I can continue my project. From Niklas I learned that video routing activities in the upstream kernel have been somehow halted. It's a pity. As a fresh guy in this particular topic one week ago, I was surprised: I found on Internet patches from last 2-3 years, the work seemed to be quite advanced, but it hasn't been merged to the upstream yet. From my side, I think video routing is important for targets processing heavily video streams, like FPGA accelerators. Unfortunately, due to my time constraints these days, I can't help in pushing the changes.
