Create 4K video with Mjpeg codec in ffmpeg
25 novembre 2018, par SulliI’m trying to produce a simple 6 seconds video clip by zooming on an image (.mov output, mjpeg codec). I can get this command to work when I set the output to be 1920x1080 :
ffmpeg -y -r 25 -nostdin -loop 1 -i input.jpg -vf "zoompan=z='min(zoom+0.0015,1.5)':d=700:x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)'" -c:v mjpeg -qscale:v 1 -t 6 -s "1920x1080" "test/output.mov"but it’s not working anymore when I set the output to be 4K (3840x2160) : the command hangs, is killed or produces a corrupted output.
My input.jpg resolution is 4240x2832.
What am I missing ?

Not able to scale, pad and combine 2 videos using FFmpeg
21 novembre 2018, par MayankI am using FFMpeg to scale, pad and merge 2 videos and generate one mp4 file. I am using the following command which leads to an output file with no audio for few seconds in the middle of the second video. Also, there is a faint white border displayed for few seconds on the black frame that I am creating. Though there are no errors in the command but I am getting a warning "[swscaler @ 0x6987800] Warning : data is not aligned ! This can lead to a speed loss".
I checked other posts here and tried the solutions provided but it didn’t work for me. It would be great if some one can help point out what I am missing.
Thanks in advance.
Here is the command :
ffmpeg -i 1_a.opus -i 2_a.opus -itsoffset 0.024181 -i 01_v.webm -itsoffset 0.113192 -i 02_v.webm -filter_complex \

How to remove everything but video and stereo audio stream from video with ffmpeg ?
20 octobre 2019, par user3776738I’m trying to get a clean h264 video from a mkv file.With clean I mean that it has only a video stream plus stereo sound.
The inputfile can have multiple channels and subtitles and other unknown stuff, which I don’t need.
I’m using ffmpeg with this command :ffmpeg -i "input.mkv" -ac 2 -vf scale=trunc(oh*a/2)*2:480 -c:v libx264 "output.mp4"This should give me a 480p video with stereo sound,which I require.
I tried multiple -map or dispositions commands with ffmpeg to remove the subtitles whithout any success.How can I remove everything but video and stereo stream with ffmpeg and get a 480p stereo sound video ?
Edit :
Output of ffmpeg - "input.mkv" -i "output.mp4" :ffmpeg -i "input.mkv" -i "output.mp4"
