Video

Type of videos supported

This library supports common video formats such as MP4, AVI, MOV, and MKV. For best compatibility, use MP4 (H.264 codec).

Reading video

The class VideoHandler can read video files and provide frame-by-frame access. It supports various formats and allows synchronization with time series data.

import pynaviz as viz

handler = viz.VideoHandler("path_to_video.mp4")

handler.get(10.0) # Returns the frame closest to 10 seconds

You can specify the timestamps for each frame if needed:

import numpy as np
import pynaviz as viz
timestamps = np.arange(0, 100, 0.033)  # Example timestamps for 30 FPS video
handler = viz.VideoHandler("path_to_video.mp4", time=timestamps)

Simple video display

import pynaviz as viz

handler = viz.VideoHandler("path_to_video.mp4")

v = viz.PlotVideo(handler)
v.show()

Videos can be display by providing the path directly:

import pynaviz as viz

v = viz.PlotVideo("path_to_video.mp4")
v.show()

Video display with pyqt6

import pynaviz as viz

handler = viz.VideoHandler("path_to_video.mp4")

v = viz.VideoWidget(handler)
v.show()

Videos can be display by providing the path directly:

import pynaviz as viz

v = viz.VideoWidget("path_to_video.mp4")
v.show()
