Hi -

Unless you are logged in as root you must "sudo ./load". If this does not work you might try installing v4l-utils and try again.

I'm on arch linux. I was getting a similar error (videobuf2-core missing), but it seems to be included as videobuf2-common on this distro. I'm not sure about this though.

v4l-utils installed, to run sudo ./load but still same error.

before was videobuf2-core missing, but afrer reinstalling TBS drivers i see that error:
modprobe: ERROR: could not insert 'videobuf2_v4l2': Invalid argument
modprobe: ERROR: could not insert 'videobuf2_v4l2': Invalid argument
insmod: ERROR: could not insert module ntv2video.ko: Unknown symbol in module

Linux www 5.0.5-arch1-1-ARCH #1 SMP PREEMPT Wed Mar 27 17:53:10 UTC 2019 x86_64 GNU/Linux
sudo ./load
insmod: ERROR: could not insert module ntv2video.ko: Unknown symbol in module

I'm also getting build errors related to the following lines:

ntv2_params.c
do_gettimeofday(&tv);

ntv2_v4l2ops.c
.vidioc_cropcap = ntv2_cropcap,

Hi -

Thanks for reporting this. I will look into it as soon as I have a system with a 5.0 kernel.

I have update the driver to fix the build errors.

Working on 5.1.2 also. On Arch Linux, I'm using these modifications to the load script:

-/sbin/modprobe videobuf2-core
+/sbin/modprobe videobuf-vmalloc
+/sbin/modprobe videobuf2-common
+/sbin/modprobe videobuf2-dma-contig
+/sbin/modprobe videobuf2-dma-sg
+/sbin/modprobe videobuf2-dvb
+/sbin/modprobe videobuf2-memops
+/sbin/modprobe videobuf2-v4l2

I doubt all of those are required; I basically included anything related to videobuf2 until it worked. It probably only needs videobuf2-common.

No longer working for me on Arch Linux 5.4.13. Fails while loading the driver:

Hi. Looks like you have some videobuf-* modules linked in which will not work. The driver requires videobuf2-*. It appears the videobuf2-core module name has been changed to videobuf2-common. I have fixed the "make load" to load the correct module. This works for me in 5.3. Let me know if it works for you. Thanks.

Can you try on 5.4? I don't think I had ever had any problems on 5.3.
