Hi, I am having the same issue. Does anyone have a solution? Thank you!
Hello
This is a known issue of V4L2 on TX2 made by the NVidia engineers. There are two solutions: 1) Look at https://github.com/TheImagingSource/tiscamera/issues/268 That may helps 2) Uses Aravis instead of v4l2. Download file aravis_usbvision_0_10.zip and copy it into your tiscamera directory of your TX2. Then perform following steps:
cd tiscamera
patch -p1 aravis_usbvision_0_10.patch
mkdir build
cd build
cmake -DBUILD_ARAVIS=ON -DBUILD_TOOLS=ON ..
make
sudo make install
tcam-ctrl should list the USB camera as "aravis" now.
DFK 37UX265 ARAVIS 34819936
== known problems indexing takes long -> aravis issue. gige-daemon only lists gige devices not UsbVision high framerates do not work -> aravis issue.
The second method is safer than patching the Kernel. But Aravis is somewhat less performant, than v4l2.
I forgot to mention: I was told, the "development" branch of tiscamera does not use the UVC Exntion anymore. Thus the first step should be check out and build this branch. I must admit, I had no time testing that on my own.
I hope, this helps

Hi Stefan,
We first tried the aravis solution but we couldn't make it work. In the end, with the solution in #268 it finally works! Thank you very much for your help!
You can close this issue for my part.
Thank you very much for your feedback!
Hi, I am trying to modify the properties of my DFK33ux252 on a NVIDIA Jetson TX2 board. I am having issues retrieving the properties using tcam-ctrl (using tiscamera last version driver). It only shows very few properties, comparing with my desktop computer (see properties below). Thank you!
