How could I get the whole video from a ndi resource?

[guCiel]

According to your example, i can get image by recv_capture ,but it depends on how the while circulation fast. if a ndi resource is playing a video, how can I get a while video to save as v1.mov in local file.

Thank you for everything.

Hi, are you using cv2.VideoWriter for video encoding?
cv2.VideoWriter connot respect a time due to frame based.
I added example for recieving with PyAV. Please see ec6bf44

I tried it in the following environment.

Python 3.10.4
ndi-python 5.1.1.1
PyAV 9.0.2

pip install ndi-python av
python recv_av.py

I hope to help you.
