HEADLESS=True yet recieving GStreamer warnings

[ohioacer]

@nicholaskajoh, I really appreciate your project.

An issue I am experiencing is I'm still receiving GStreamer warnings despite the HEADLESS=True setting in the .env file (I used the .env.example).

The error I received when I typed python3 -m main is as follows:

Opening in BLOCKING MODE
NvMMLiteOpen : Block : BlockType = 261
NVMEDIA: Reading vendor.tegra.display-size : status: 6
NvMMLiteBlockCreate : Block : BlockType = 261

The file sample_traffic_scene.mp4 is there though in the proper directory (I downloaded it from the Google Drive link given in README).

I'm running it on Ubuntu on a Jetson Nano. Python 3 version 3.6.9

Please run find . in the project root and share the result here. I want to confirm the video file was placed in the path the code is using.

[nicholaskajoh]

Does it work when HEADLESS is False?

[ohioacer]

Yup yup. Same result in both states of Headless.

[ahmadkammonah]

I have the same error:

Invalid video source /mnt/c/Users/Ahmad Kammonah/Desktop/Ahmad/Python Test/OpenCV/assets/inputVideo.mp4 {'label': 'INVALID_VIDEO_SOURCE'}

Did anyone find a solution?
