Bodypix scaling breaks fake.py (?)

[liske]

Is it possible that c156ee9 had broken fake.py? I'm not sure if it is related to my docker setup, does it work for you @fangfufu ?

It works for me. Are you using Python 3?

Ah, do note that bodypix_url='http://127.0.0.1:9000'. Previously bodypix_url='http://fakecam:9000'.

I used the updated Dockerfile using python3 and native Debian packages for the requirements (only pyfakecam is installed using pip).

There was some more errors before which was scrolled out of my terminal:

fakecam_1  | [ WARN:0] global ../modules/videoio/src/cap_gstreamer.cpp (480) isPipelinePlaying OpenCV | GStreamer warning: GStreamer: pipeline have not been created
fakecam_1  | [ERROR:0] global ../modules/videoio/src/cap.cpp (116) open VIDEOIO(GSTREAMER): raised OpenCV exception:
fakecam_1  | 
fakecam_1  | OpenCV(4.2.0) ../modules/videoio/src/cap_gstreamer.cpp:743: error: (-215:Assertion failed) uridecodebin in function 'open'

Since it use network_mode: host the new bodypix_url is working (there is no more docker network around for the containers).

If it is working for you it is related to the dockered stuff... so I need to review it.

I can't really tell if it failed to open the real webcam or the virtual webcam.

[liske]

It was nothing docker related. I'm using my Android phone as webcam (using adb-ffmpeg-v4l2loopback) and I've just used the wrong resolution of 640x360 instead of 1280x720 (pick the wrong line from my bash history).

Now it is working again, although the following messages are still there:

fakecam_1  | [ WARN:0] global ../modules/videoio/src/cap_gstreamer.cpp (480) isPipelinePlaying OpenCV | GStreamer warning: GStreamer: pipeline have not been created
fakecam_1  | [ERROR:0] global ../modules/videoio/src/cap.cpp (116) open VIDEOIO(GSTREAMER): raised OpenCV exception:

Glad that you got it sorted.

On a side note, I do have needrestart installed on my machines. It works great. I feel this is my 5 mins of fame. ;)
