Python backtrace
Another portrait input video with format 406 × 720 produces a similar Blender crash.
Your extension appears in Blender only when running sudo ./blender, not ./blender.
Could the problem here be related to other installed software? I have several versions of opencv, mediapipe and probably pip on my system from other blender extensions that use mediapipe. Unlike your extension these do not have an uninstall software command, making removing the offending versions difficult.
Great work here. Looking forward to using this.
Similar problem in new Fedora 36 installation.
Removing and reinstalling dependencies did not help.
Hand markers are displayed in the movie frame that flashes for a few seconds before Blender crashes.
Here is blender.crash.txt
Terminal output follows.

I'm not familiar with fedora and sadly my VM doesn't let me install it properly so I cannot test myself. Anyways, I did some research and you could try the following:
- Don't set the stream frame writable flags to false:
- navigate to
src/cgt_detection/cgt_detector_interface.py - comment out line 84:
# self.stream.frame.flags.writable = False
- Try downgrading mediapipe :
- find the path to blenders python.exe in blenders python console with the cmd:
sys.executable - shutdown blender, open the terminal and uninstall mediapipe:
'python.exe-path' -m pip uninstall mediapipe - install older mediapipe versions:
'python.exe-path' -m pip install mediapipe==0.8.7 - (I'd try versions in between 0.7 - 0.10, but 0.8.7 seems to be a good first test)
Your extension appears in Blender only when running sudo ./blender, not ./blender.
Weird, this should only be an issue when installing the dependencies, maybe there is a permission issue? Can you provide a log message?
Unlike your extension these do not have an uninstall software command, making removing the offending versions difficult.
Yes, there can be issues. The requirements can be fairly specific (which is a bummer). I included an "uninstall dependencies" button as sometimes it's required to use specific package versions. Using it may break other tools. Are the add-ons using mediapipe and open-cv running properly on your system? If so, could you check the mediapipe / open-cv-contrib versions or send me a link to their git?
I'll try your suggestions today and reply.
Just installed Blender 3.0.0 thinking that the problem might be an extension compatibility issue with newer Blender versions but from the output below it appears the same problem exists with the 3.0 version.
When I did a fresh install of Fedora 36 two days back I assumed it would eliminate any old versions of mediapipe, openCV and pip, but that is apparently not the problem here, unless those versions reside in my /home data partition. That seems unlikely.
Below is the terminal output for Blender 3.0.0, which has some warnings about running pip as root user and using an old version of pip, but maybe those are not important?

Will reply to your other suggestions in a bit.
Your extension appears in Blender only when running sudo ./blender, not ./blender.
Weird, this should only be an issue when installing the dependencies, maybe there is a permission issue? Can you provide a log message?
This issue disappeared. The addon is visible without running sudo ... not sure why the change happened.
Unlike your extension these do not have an uninstall software command, making removing the offending versions difficult.Yes, there can be issues. The requirements can be fairly specific (which is a bummer). I included an "uninstall dependencies" button as sometimes it's required to use specific package versions. Using it may break other tools. Are the add-ons using mediapipe and open-cv running properly on your system? If so, could you check the mediapipe / open-cv-contrib versions or send me a link to their git?
The other mediapipe addons I had been using are changing quickly. Close2animation has gone off the radar. Carlos has a Blender mediapipe addon at https://github.com/carlosedubarreto/b3d_mocap_import. It requires a lot of downloads and I don't have it installed on a current Blender version.
I just tried BlendyPose in Blender 2.93 and it worked well for limited display of mediapipe's capability, though it crashes after finishing the video. BlendyPose has a new fork at https://github.com/SpectralVectors/PosePipe that I will try to install, just for testing. For some reason installing new addons in Blender in Fedora 36 is now problematic.

Attempting to change to mediapipe0.8.5 gave the following:

Changing to the latest mediapipe0.8.10.1 in Blender3.2.1 gives a fullsize upside down output display with markers. After a few seconds Blender crashes again.

Sorry for the multiple posts above - some strange thing with Github at that time. Fedora 36 seems better in that regard.
Most of the problems I mentioned in this issue have disappeared in Fedora 36 running Blender 3.3.1, probably thanks largely to upgrades especially in the development branch.
One problem that remains with some movies is that the video is shown upside down and therefore has little Mocap detection. For me this happens with higher res video from a Samsung Note5 camera. Some other internet and mobile camera movies work fine, with normal right-side-up display.
The only other issue is jittering of the mocap. Will try the smoothing you describe in the documentation. Am wondering whether the mediapipe smooth_landmarks and smooth_segmentation commands might be good selectable options. https://google.github.io/mediapipe/solutions/pose#smooth_landmarks
From all the informations I've gathered over the time the issue is usually based on either the mediapipe or the opencv binary. Sadly I can only recommend manual work in this case. The following informations are based on the current version on the main branch - I'll create a release soon.
- The current mediapipe version 0.9.1.0 comes with opencv-contrib-python 4.7.0.68
- opencv-contrib-python 4.7.0.68 may leads to binary issues - 4.5.5.64 seems to be more stable but it's not foolproof. On some system you may want to install opencv via your local package manager.
- In the current BlendArMocap version (main branch) the local user site-packages are getting imported (before the release I'll make it optional in the prefs, so you might have to toggle a boolean button).
- Make sure to not install any of mediapipe 0.8.x releases - they have corrupted dependency tree by default.
- Make sure to not have multiple opencv packages installed at one (like headless+opencv+opencvcontrib). To check it use the cmd
python3 -m pip freeze | grep cv.
TL;DR Most likely you'll have to install dependencies manually and fix common linux issues:
// test if the default mp package does the trick
python3 -m pip install mediapipe==0.9.1.0
// try installing another opencv version
python3 -m pip uninstall opencv-contrib-python
// check for remains (sometimes pip fails and you have to remove them manually)
python3 -m pip freeze | grep cv
python3 -m pip install opencv-contrib-python==4.5.5.64
// if that still doesn't work, remove it and consider to install other cv2 versions or install it with your local package manger
Thanks for explaining this. After an upgrade to Fedora 37, running the command, "python3 -m pip freeze | grep cv" gave no output, which seems like a good result.
