Online trimming with FFMPEG

[danielko]

Hi everybody,

does ffmpeg supports trimming of a online video content?
I.e. if I want to trim and download only a certain part of a online video content, instead of downloading the entire video.

Thank you

ffmpeg -t XXXX .......

start at: -ss HH:MM:SS.ddd
length: -t HH:MM:SS.ddd

start at: -ss HH:MM:SS.ddd
length: -t HH:MM:SS.ddd

Can you please give an example, let's say for this video:

1. In ffmpeg: youtube-dl -g "YOUR YOUTUBE LINK"

Ffmpeg will find 2 links, 1 for audio, 1 for video.

2. Copy and paste in the following command:

ffmpeg -ss 27:11 -i "FIRST LINK" -ss 27:11 -i "SECOND LINK" -map 0:v -map 1:a -t 0:08 -c:v libx264 -c:a aac FILENAME.mkv

-ss is starting point of the video and audio links (in this case 27:11) and -t is how many seconds/minutes/hours to cut from -ss (in this case 8 seconds)
