How to extract a sub portion of a large video file
25 juin 2012, par user1478077I want to extract a small portion of video from a large video file on the basis of a given start and end time.
My internet search shows that many suggest using Xuggle to do this, but I am unfamiliar with this library, its use, or how one can use it to achieve my goals. Please help me with this.

Why ffmpeg/mplayer2 play sloppy something that vlc plays well ?
8 octobre 2015, par exebookWhile trying to play with mplayer2 or stream with ffmpeg, the video has a slight delay about every 12 seconds. Sometimes leading to distorted picture. But the same input plays back perfectly with vlc. What could be the reason for this ?
mplayer2 shows it’s infamous "YOUR SYSTEM IS TOO SLOW TO PLAY THIS", but neither of its suggestions make difference.

How to get FFmpeg to consistently apply speed effect to first few frames ?
16 janvier 2021, par melody_florumI am using FFmpeg to apply speed effects to short gifs and videos and I noticed strange stuttering on looping gifs when sped up. I manually tested and found what was going on. FFmpeg failed to apply the speed filter to the first few frames of the video.


I started with this file, which loops between the numbers "1 2 3 4" every frame.




I then ran the command
ffmpeg -i 123410fps.mp4 -vf setpts=0.5*PTS 123410fpsout.mp4


That left me with this file : 123410fpsout.mp4


On close analysis, I discovered that the output file didn't show a repeating
1 3 1 3
or2 4 2 4
pattern, but shows1 2 3 4 1 3 1 3 1 3...
the speed effect didn't apply for the first few frames

I apologize if it sounds like i'm being super nitpicky, but my usage for this is on very short gifs and videos where this effect is very apparent. How can I prevent this effect from happening and have a 100% consistent speed effect applied to the video ? I don't mind using other non-ffmpeg software but a CLI solution that works easily for most videos is ideal.


In case anyone is wondering, I don't use ffmpeg to encode gifs, i use gifski from ffmpeg exported image sequences. The problem shows up even when no gifs are used, so it's not a gifski problem.
