Hello,
You can follow these steps to perform "webread" and analyze the video from the given link -
1. Download video data from the link using "webread
videoData = webread('https://upload.wikimedia.org/wikipedia/en/transcoded/4/4c/Green_and_cyan-green_demonstration_of_frame_rate_control_FRC_4K60.webm/Green_and_cyan-green_demonstration_of_frame_rate_control_FRC_4K60.webm.160p.webm');
2. Write video data to a file using "fwrite"
fid = fopen('vid_file_name.mp4', 'w');
fwrite(fid, videoData);
fclose(fid);
3. Read the video from the file using "VideoReader"
videoObj = VideoReader('vid_file_name.mp4');
4. Capture and display the video frames using a loop that iterates over all frames in the video
while hasFrame(videoObj)
frame = readFrame(videoObj);
imshow(frame);
end
5. Now you can analyze the frames as needed
Here is the example code -
% Download the video data
videoData = webread('https://upload.wikimedia.org/wikipedia/en/transcoded/4/4c/Green_and_cyan-green_demonstration_of_frame_rate_control_FRC_4K60.webm/Green_and_cyan-green_demonstration_of_frame_rate_control_FRC_4K60.webm.160p.webm');
% Write the video data to a file
fid = fopen('vid_file_name.mp4', 'w');
fwrite(fid, videoData);
fclose(fid);
% Read the video from the file
videoObj = VideoReader('vid_file_name.mp4');
% Capture and display the video frames
while hasFrame(videoObj)
frame = readFrame(videoObj);
imshow(frame);
% Analyze the frames as needed
end
Hope this helps!
