I need to extract video frames in a folder. I have 90 videos in a folder and would like to extract each video frames in a seperate folder one time.
How could I do that?
Below is the code I tried so far but it works for one video only. I would like to do this for all the videos in a folder one time:
import os
import numpy as np
import cv2
from glob import glob
def create_dir(path):
try:
if not os.path.exists(path):
os.makedirs(path)
except OSError:
print(f"ERROR: creating directory with name {path}")
def save_frame(video_path, save_dir, gap=1):
name = video_path.split("/")[-1].split(".")[0]
save_path = os.path.join(save_dir, name)
create_dir(save_path)
cap = cv2.VideoCapture(video_path)
idx = 0
while True:
ret, frame = cap.read()
if ret == False:
cap.release()
break
if idx == 0:
cv2.imwrite(f"{save_path}/{idx}.png", frame)
else:
if idx % gap == 0:
cv2.imwrite(f"{save_path}/{idx}.png", frame)
idx += 1
if __name__ == "__main__":
video_paths = glob("D:/test_/crops/*")
save_dir = "save"
for path in video_paths:
save_frame(path, save_dir, gap=1)
import os
import numpy as np
import cv2
from glob import glob
def create_dir(path):
try:
if not os.path.exists(path):
os.makedirs(path)
except OSError:
print(f"ERROR: creating directory with name {path}")
def save_frame(video_path, save_dir, gap=1):
name = video_path.split("/")[-1].split(".")[0]
save_path = os.path.join(save_dir, name)
create_dir(save_path)
cap = cv2.VideoCapture(video_path)
idx = 0
while True:
ret, frame = cap.read()
if ret == False:
cap.release()
break
if idx == 0:
cv2.imwrite(f"{save_path}/{idx}.png", frame)
else:
if idx % gap == 0:
cv2.imwrite(f"{save_path}/{idx}.png", frame)
idx += 1
if __name__ == "__main__":
video_paths = glob("D:/test_/crops/*")
save_dir = "save"
for path in video_paths:
save_frame(path, save_dir, gap=1)
