hung when creating the avi

[juul1a]

maybe i didn't wait long enough, but after I hit stop recording the program hung here:

about to execute:
mencoder mf://*.png -mf type=png:w=800:h=600:fps=25 -ovc lavc -lavcopts vcodec=mpeg4 -oac copy -o output.avi

no output file, but all the screenshots are there and happy. any ideas?

awesome tool btw :) hope i can get it working

Oh, hey there. 👋

The tool is quite a few years old, so I forgot the details.
What happens if you run the command directly from the commandline?
Also, what Operating System are you running on and what's your version of mencoder (mencoder -v)?

We could also switch to ffmpeg as the underlying encoder, given the fact that mencoder uses ffmpeg in the background. 🤔

Nice website, btw.

Oh 😅 thank you!!

Lets see... running the command and mencoder -v gives me a good ol' command not found so that's definitely something. I just looked up mencoder for mac and people are saying it comes with MPlayer? Tried installing mencoder and mplayer using homebrew and neither of those did a thing. I'm on Mac OS 10.12.6. I do have experience ffmpeg though so maybe we just adjust it to use that without mencoder.

Thanks for hte quick reply (:

So I moved to ffmpeg and updated the docs. Can you give it another shot?

[juul1a]

Thanks! I'll download again and give it a go, then let you know. Appreciate your help + efforts (:

Ok sweet, it works!! It threw an error initially:
File "timelapse.py", line 33, in <module> class Timelapse(NSObject): File "timelapse.py", line 103, in Timelapse @objc.python_method AttributeError: 'module' object has no attribute 'python_method'
so I just went in and commented out @objc.python_method on lines 103, and 121, then it worked like a charm :)

Thanks so much for your help!

Ah yeah, that's because you have an old version of the Objective C bindings.
Something like a pip install --force-reinstall pyobjc might help.
Alternatively, I've added a requirements.txt, so you could use virtualenv and do the following:

virtualenv venv
source venv/bin/activate
pip install -r requirements.txt

Glad it works, though.
One warning: please copy the output file to a safe place after each run, because the output file is hardcoded to output.mp4 for now. 😉

Great job @mre!
However I didn't see the requirements.txt in this repo

[mre]

Oh, thanks for the heads-up @ju5td0m7m1nd. Pushed it to the repo now. 👍

I think this can be closed now.
