video show no content

[utixx]

simple code, but output video shows no content.

checked that variant video has value and have installed ffmpeg and set it in the system path.

Unfortunately I cannot reproduce the problem.

Does it work when ran in Colab, e.g., https://colab.research.google.com/github/google/mediapy/blob/main/mediapy_examples.ipynb ?

Please try !pip show mediapy to see the version number, and similarly !ffmpeg -version.

Also, try generating the video at size (200, 200) and pressing the play/pause button in the video window.

It works well in Colab and Chrome.

But the problem still exists in PyCharm.

I have not used PyCharm. Access to Jupyter notebook requires PyCharm Pro? It could be that the display of videos as implemented by mediapy does not function under PyCharm.

You could also try:

media.show_video(video, fps=10, codec='gif')

This uses an <img> rather than <video> HTML element.

‘gif’ works.

btw, why can't mediapy display video when using the plugin Jupyter notebook in PyCharm Pro?

Probably PyCharm does not support the display of HTML
