use yolo_prune to run video error

[107060009]

I ran the work in yolo_prune folder, and I got the result by ./yolo ./image/ i. But I ran into an error when I inference the model by the following command :
./yolo {VideoFileName.avi} v

The error message is :

Failed to query video capabilities: Inappropriate ioctl for device
libv4l2: error getting capabilities: Inappropriate ioctl for device
VIDEOIO ERROR: V4L: device ./video/road_trafifc.mp4: Unable to query number of channels

open video error!

It seems like missing some Gstreamer plugins, and I wonder how to solve it or tell me another way to run the video input successfully.
Thank you!

It seems like your video file or camera has some problem. Try another video or device first

Is the video supposed to be .avi or .mp4 file?
Or there are some restrictions for the input video?

Sorry, I don't remember the content in yolo_prune. I recommend you turn into the yolo_keras in this project.

And for your problem, try another video or just one image to see if the code works well.

I tried one image as input, and yolo_prune works well.

I also tried the work in yolo_keras.
I ran the Makefile in yolo_keras/yolo_pynq2 and generated the yolo executable file.
However, when I ran the command:
./yolo dog.jpg
the pynqz2 unexpectedly disconnected the network and then shut down.
Is there any problem in my steps?

Unexpectedly shutting down usually means the power input is not enough. If you follow the steps in the guideline, it should work. It is hard for me to reproduce your problem.
