Arch Linux User Repository

@jose1711 fixed

currently it's incompatible with opencv 4. to workaround disable by passing -DPLUGIN_INPUT_OPENCV=OFF to cmake

There is some minor wackiness going on with the PKGBUILD here. If you're trying to set CMAKE_BUILD_TYPE in package(), the bash-ism $() will try to run the command within the parenthesis. CMAKE_BUILD_TYPE is (probably) intended to be a variable, not an executed command. The CMAKE_BUILD_TYPE defaults to Release in the mjpg-streamer CMakeLists.txt, so setting this here is unnecessary (unless you actually wanted it to be Debug, but probably not).

I cannot maintain this package any longer. Hope that someone will do it.

I think this may be a fault in my two cameras; looking at the v4l2 output I see this

v4l2-ctl --list-formats
ioctl: VIDIOC_ENUM_FMT
Index : 0
Type : Video Capture
Pixel Format: 'YUYV'
Name : YUYV 4:2:2

so it seems neither allows for mjpeg; sorry for noise.

I have done clean installs on two x64 machines running latest Arch. When I use -i "input_uvc.so -y" I see things fine. When I run without I see the website, but the stream contains no data.

I did some debugging (even added some of my own) and there is data being grabbed and passed to the cam_thread (at least the length appears to be 2 x 640 x 480), but I don't see any frames appearing in the stream

@replabrobin I have no problem upgrading to linux 4.2.5-1. What happens if you perform a clean installation of mjpg-streamer?

I'm finding that the problem with mjpeg is back even with the patch in place; course my kernel is 4.2.5-1

Please add armv6h to architectures for raspberry pi :-)
