Recently, i notice that the downloaded video distorts if i try to forward/backward seek. I have created a config file and below are the contents of it.

-o ~/Downloads/Youtube/%(title)s.%(ext)s

-f 'bv[height=1080][ext=mp4]+ba[ext=m4a]' --merge-output-format mp4

-f 'bv+ba/b' --merge-output-format mp4

Any idea if I’m using any setting wrongly? please suggest a better way?

vada-pav commented 2 years ago

My bad. I am new to this and did not know how to interpret the text instructions. Do i need to change anything in order for video to not distort while seeking?

Lesmiscore commented 2 years ago

The video does seek properly (both forward/backward) without any visible errors to me. Try changing player or ffmpeg

Change ffmpeg? How? I use vlc media player. Could it be because of it? Any recommendations for players on mac?

This is the distortion i see. Screenshot 2022-07-31 at 5 06 01 PM

It is possible your video player cannot properly handle vp9 in mp4. I suggest you try playing in latest version of ffplay/mpv to confirm

yt-dlp / yt-dlp

Video distorts after downloading? Weird behaviour. #4500
