Create muted video and black screen video with FFmpeg on OS X
22 septembre 2017, par user2685832I’m trying to use FFmpeg on OS X to generate the following from a local mp4-file :
- A copy of the original video with no audio
- A copy of the original video with audio but without visuals (a black screen instead). This file also needs to be in mp4 format.
After reading through the documentation I am struggling to get the terminal commands right. To remove the audio I have tried this command without any success :
ffmpeg -i file.mp4 -map 0:0 -map 0:2 -acodec copy -vcodec copy
Could anyone guide me towards how to accomplish this ?
Thanks !

ffmpeg : given a video of any length, create timelapse video of 6-8 seconds long
14 mai 2018, par CDubI have an application which consumes video of any length (could be a few seconds, could be several minutes) and I want to use
ffmpeg
to return a "timelapse" version of the input video which will always be between 6 and 8 seconds long.I’ve been fiddling with the following :
ffmpeg -y -i in.mp4 -r 10 -vf setpts='0.01*PTS' -an out.mp4
Which seems to be a good start, but still generates very dynamic results given what
in.mp4
is.I also don’t fully understand the verbiage in the ffmpeg documentation, so I’m not even sure what arguments to use for
setpts
, or ifsetpts
is the correct filter I want to use. -
Is there a way to display video, then an image, then more video using OpenCV ?
24 septembre 2015, par kdibene1I have a bunch of frames (jpg images) and want to stitch some of them together and make a video, then display one image (essentially repeating the same frame for a number of seconds) and then stitch more frames together and continue playing the video. I want it to be continuous with no interruptions, is this possible ? I know about avconv and ffmpeg, but they only stitch together frames and make a video, they do not simply display a frame over and over again like with ImageMagick. Essentially what I want to do is take a bunch of image frames, stitch them together to an arbitrary point, then display an image, then stitch together the remaining frames to a video.
Can anyone help ?
