Extract specific frames of youtube video without downloading video
22 janvier 2023, par Kashish AroraI need to extract specific frames of an online video to work on an algorithm but I don't want to download the whole video because that would make it highly inefficient.


For starters, I tried working with youtube videos. I can download whole of the video using
youtube-dl
in this way :

ydl_opts = {'outtmpl': r'OUTPUT_DIRECTORY_HERE',}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
 ydl.download([url])



And then I can capture individual frames.


I need to avoid downloading the whole video. After some research, I have found that
ffmpeg
might help me do this. I found no way to download just the frames so if this is not possible, the second option is that I can download specific portions of the video. One such example in linux is here but I couldn't find any solution for python.

What is a good way to download just the frames, or portions of videos (in python) without downloading the entire thing ?

How to extract a video segment from a video using FFMPEG ?
7 février 2013, par WajihI am a newbie to FFMPEG, I am stuck at using FFMPEG to extract a segment of video. Since I am using the direct command line interface.
What would be the command line arguments if I am to extract say, video from frame 0 to frame 100000 or if I wanted to extract a video segment of 1 hour from a video that is 5 hours long ?Thanks !
