No more stabilised data, unplayable video about gyroflow

[ElvinC]

Thanks for the info about what encoders work. The progress percent is not really "stuck" since it doesn't print a message after completion (sorry about that) no more stabilization data should also terminate and save the file, so it was a problem with the encoder.

Oops, ignore prior to my edits. I have exactly the same error on a 2015 Macbook, also tried same options as Sebastian, and behavior is the same: gyroflow runs but the output doesn't open in Quicktime. Davinci Resolve shows the media as "offline" when imported. Opens in VLC but not quite sure what to do with it since it doesn't work in Resolve :)

@petervieth sorry, forgot to add a message here. If you're using the executable, then the bug should have been fixed on the master branch. Let me know if you're still having problems using that. New executables will be out soonish.

Thanks for the explanation. Unfortunately I don't use python and getting it working on Mac is not fun (I just tried again for half an hour and gave up). I know clobbering python 2.7 is bad. EDIT: While I have your attention... is there some way to output in the src frame rate? I have 29.97 going in but 50 going out. I also shoot in 59.94 on GH5; this test footage is from GX85 on a cinelifter. EDIT2: I tried on a Windows machine but poetry cannot find opencv. I realize this is the wrong place to ask these questions, if you have a recommendation let me know.

@petervieth Did you run poetry install first, followed by poetry run python gyroflow.py? I just tried with a fresh clone of the master branch and didn't have any issues. Can you send the the error messages you're getting?

[petervieth]

Yes, I went to the poetry site and followed the instructions. I can't seem to figure out how to get it to save the environment once I close the shell though (I just ran it using $HOME/.poetry/bin/poetry )

On Windows, the error is: Unable to find installation candidates for opencv-python (4.1.2.30)
On MacOS: NoCompatiblePythonVersionFound
But I installed python 3.7 so I know that's not true (pyenv install 3.7.0), it probably just can't find it and I'm not sure how to tell it where it is, or where 3.7 lives.
EDIT: I used to be a Java and C++ developer until 2010, have only written firmware and Javascript since then. So I know the pain of Java development environments, and I assume python is the modern form of masochism :)

[petervieth]

It's because I was using Python 3.9 and you're using something earlier. There is no 4.1.2 of opencv-python for 3.9 of any architecture, which is why poetry can't find it. I figured this out by trying to use a local repo. Maybe you wish to add a note about this to the webpage for python n00bs like myself :)

@petervieth oooh that makes sense, nice find. I'll make sure to add a note. Thanks!
