Unrecognized option 'qp'

[nju-cn]

Hi, I run the code but it occurs the problem "Unrecognized option 'qp'". What's wrong with it?

It is most likely due to the ffmpeg version is too low. Conda will implicitly install an old version of ffmpeg when installing opencv. So you may need to install ffmpeg manually.

Hi, thanks for your work. That's interesting. A question is that the bandwidth estimator is not released in the current version, right ?
Thanks

The problem is caused by ffmpeg version, but it is not because your version is too low. I came up with the same problem with my version is 4.3.

ffmpeg                    4.3 

But the problem is fixed when I degrade it to 4.2.2.

ffmpeg=4.2.2

I got inspiration from https://github.com/Zulko/moviepy/issues/657#issuecomment-972144503. Hope to help!

Run ffmpeg -version and check whether you have --enable-libx264 in configuration. If not try rebuild it with the enable libx264 flag
