• Not able to scale, pad and combine 2 videos using FFmpeg

  21 novembre 2018, par Mayank

  I 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 \

• Create 4K video with Mjpeg codec in ffmpeg

  25 novembre 2018, par Sulli

  I’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 ?

• FFmpeg : How to apply volume filter fast in ffmpeg

  29 novembre 2018, par Prashant_Sarin

  i am using below code for applying volume filter in ffmpeg, but its taking too long.Let’s say the audio itself is for 5 minutes then applying this filter takes 3 minutes. Can someone help to speed up the process.

  my command is as :

  var command = "-i $audioPath -af volume=enable='between(t,5,10)':volume=0.25,volume=enable='between(t,15,20)':volume=0.25 $outputFile"
