Detailed description
The test produces video with synthetic frames and decodes it with same backend. GStreamer back-end produced video with some duplicated frames and loose user frames.
Steps to reproduce
- Install GStreamer
- Run videoio test
./bin/opencv_test_videoio
Issue submission checklist
- I report the issue, it's not a question
- I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
- I updated to the latest OpenCV version and the issue is still there
- There is reproducer code and related data files (videos, images, onnx, etc)
