Error: ROI17_TOI-failed to compute the signal

[kadnan]

I am getting bunch of errors while running the command python dfxdemo.py measure make vid.mp4. The error dump is below:

You might be loading two sets of Qt binaries into the same process. Check that all plugins are compiled against the right Qt binaries. Export DYLD_PRINT_LIBRARIES=1 and check that only one set of binaries are being loaded.
QObject::moveToThread: Current thread (0x7fb42e521030) is not the object's thread (0x7fb43682b660).

I installed pip install opencv-python-headless and now it says:

On dashboard it shows status as In Progress

Hello Adnan,

If you use opencv-headless, there is no GUI support. If so, please run python dfxdemo.py measure make --no_render so that the demo doesn't attempt to show any GUI.

That said, your Status 400 seems to indicate an issue on the server. I will ask someone from the backend team to take a look.

Hello @kadnan ,

Please make sure that you are using the latest Python demo client. You should see a message saying Loaded: mobile20200702 before you see Created DFX Collector.

If the issue persists, please send us the payloads generated with --debug_save_chunks_folder as an argument when making a measurement, or the video you used.

[kadnan]

@YukeSW I just cloned a couple of days back. ARe you saying to run a git pull of this repo?

[YukeSW]

If you just cloned a few days ago, it should be the latest version. You can still run a git pull to make sure.

If you still see that error, please send us the payloads or the video.

@YukeSW Here I got the error dump:

By enabling debugging it generated 3 files:

[YukeSW]

From your payload, it seems your video has a low FPS. The expected FPS for Deepaffex to work is 30.

Please try if our sample video works for you. You can find it in Sample Data at https://deepaffex.ai/developers-sdk when you scroll the page to the bottom.

[kadnan]

@YukeSW The sample file worked well and I can see graph on Deepaffex website. My measurementId is 851ce148-f729-40f8-bf05-e1bef2d061c6 in case if you want to check further.

What should we do while making videos? The earlier videos i made from my mobile for ~ 30 seconds

[YukeSW]

In general, a mobile camera (iPhone preferable) should work for a 30 FPS camera, and a rear camera is better than the front one.

The FPS of your video was about 17 FPS based on the payload. You might want to try to record a new video or try a new camera.
