About the 404 error, I have the same problem.

It may happen when the deskshare video is not a video but just images from presentation.

I was able to generate the missing video with following steps:

  • Open shapes.svg
  • You will have all slides.
  • Generate a file (data.txt in the same output directory than the one specified to download.py) that will have:

file 'presentation/xx-yy/slide-1.png'
duration 746.4
file 'presentation/xx-yy/slide-2.png'
duration 204.9
...
To get duration, substract out - in

Finally run:

ffmpeg -f concat -i .\data.txt -vf fps=2 -c:v libx264 -preset veryslow -crf 22 -aq-mode 3 -pix_fmt yuv420p out.mkv

If you increase fps too much, ffmpeg may take huge amount of memory (20 Go) in my case.

I manually did it with regex and excel (for substract) but it could be done in a small py script I think.
