nv21
Functions for reading and decoding the data of frames in NV21 format.
Basically it wraps the cv2-based conversion with some check in order to avoid some confusing cv2 errors.
Available functions
nv21_to_rgbread_nv21_from_fileyuv_to_nv21
Example
import cv2
import matplotlib.pyplot as plt # do not forget to install `matplotlib` first
import nv21
# Check the "data" folder of this repository.
img = cv2.imread('./data/example.png')[..., ::-1] # to RGB
h, w = img.shape[:2]
nv21_data = nv21.yuv_to_nv21(
cv2.cvtColor(img, cv2.COLOR_RGB2YUV)
)
restored_img = nv21.nv21_to_rgb(nv21_data, w, h)
# Draw results
plt.subplot(1, 3, 1)
plt.axis('off')
plt.imshow(img)
plt.subplot(1, 3, 2)
plt.axis('off')
plt.imshow(nv21_data, cmap='gray')
plt.subplot(1, 3, 3)
plt.axis('off')
plt.imshow(restored_img)
plt.show()
