• Creating a simple transition between all images in a folder

  28 mai 2014, par Vikram

  I am trying to make ffmpeg pick up every picture file in a folder (pngs, for example) and create a video (in mp4, for example), but put a blend transition in between all photos in one command? Any ideas?

  Thanks for all your help!

• Convert YUV to MP4 and YUV with one FFmpeg command

  27 mai 2014, par user3319828

  I want to encode an input YUV file to an output MP4 file and also generate a YUV file with the same quality as the MP4 file. However, when I type the following code, the generated YUV file is just a copy of the input file:

  ffmpeg -y -s 352x288 -i inp.yuv -crf 31 -r 30 -pix_fmt yuv420p -c:v libx264 out.mp4 out.yuv
  

  One way I can solve the problem is to first generate the MP4 file using one command and then type another command to convert the MP4 file to YUV:

  ffmpeg -y -s 352x288 -i inp.yuv -crf 31 -r 30 -pix_fmt yuv420p -c:v libx264 out.mp4
  ffmpeg -y -i out.mp4 out.yuv
  

  Is it possible to do this only with one FFmpeg command?
