I'm receiving the error "Unable to stop the stream: Inappropriate ioctl for device" when trying to open a video file with OpenCV 3. Before marking as a duplicate, please note that I've looked at a lot of posts and none of them solved the problem for me. I've setup a virtual environment under conda.

I know there's a way to install OpenCV with conda but I don't believe it includes ffmpeg or other cuda abilities I need included. I've built the source for OpenCV 3. I've also set all of the python3 cmake variables to point to the python instance in the virtual environment in question:.

After generating the make configuration I compile inside the build directory with make -j8 then install with sudo make install. If I now start Python in the virtual environment I can import cv2, but I see the above error when I try to open a video file. I can capture video from the webcam without a problem. In python the command print cv2.

The script tries to open a file from a certain directory and it fails to read the file because file has no read permission, but I get a different error saying inappropriate ioctl for device.

If you'd show your code, I bet someone would rapidly point out your error. They can be areas on disk organized by a file system, but they could equally well be a network connection, a bit of shared memory, the buffer output from another process, a screen or a keyboard.

In order for perl to be really useful it mirrors this model very closely, and does not treat files by emulating a magnetic tape as many 4gls do. It used to be triggerred primarily by attempts to configure terminal properties e.

More generally, it is triggered when doing an ioctl on a device that does not support that ioctl, hence the error string. Then find out what file number was used, and what open call returned that file number. I just fixed this perl bug. If so whats going on is perl debug tries to query and perhaps reset the terminal width.

The alternative would be for your debug session to hang forever because you did not see the prompt for instructions. Since this is a fatal error and also quite difficult to debug, maybe the fix could be put somewhere in the provided command line? Got the inappropriate icotl for device error and tried everything that came to mind. Read just about every post on the net related to this. Obviously the problem was isolated to the mounted Windoze share on the Linux server.

Looked at the file permissions on the Windoze box and noted the files had their permissions set to read only. Changed those, went back to the Linux server and all worked as expected. This may not be the solution for most but hopefully it saves someone some time. Learn more. Asked 10 years, 8 months ago. Active 1 year, 2 months ago. Viewed k times. I have a Perl script running in an AIX box. Shouldn't it say something like no read permissions for file or something similar?

It works out of the box on both Ubuntu I also tried with the official Ubuntu packages coming in the quite old v2. Please compare output of cv::getBuildInformation from 3.

Probably you need to install additional development packages to enable this functionality when building OpenCV from sources. Could that be? Here is the full output for each: Buildinfo I've tried the same on two different machine one without any camera and then the notebookboth yielding the same result.

Yes, the internal camera works without any problems, it's just this framegrabber that makes problems. I did as you suggested sudo apt-get install libv4l-0 libv4l-devreran cmake and sudo make install and rebuilt my program.

The output is still the same though:. Still same result:. I've just pulled the latest changes and am building it again, I don't think it will make any difference to Update 2 above though. So it's not a bug in master after allso I hope it's fine if I close it. Thank you very much for your help, alalekmshabunin.

Edit CmakeVars. I had the exact same issue using Manjaro I removed the old implementation of OpenCV, went and reinstalled it from scratch. Then in the output of the Cmake installation I noticed Can't find ffmpeg - 'pkg-config' utility is missing.

Installed the pkg-config and re ran cmake, make and now everything works. And if you compile and install the opencv without FFMPEG, you will get error "Unable to stop the stream: Inappropriate ioctl for device" for video related samples. This is:. Unspecified error The function is not implemented.
