• Fade Video-Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

  27 octobre 2018, par varmashrivastava

  I am using below command to add Fade In Fade Out effect to my video

  {"-y", "-ss", "" + startMs / 1000, "-t", "" + (endMs - startMs) / 1000, "-i", inputPath, "-acodec", "copy", "-vf", "fade=t=in:st=0:d=5,fade=t=out:st=" + String.valueOf((endMs - startMs) / 1000 - 5) + ":d=5", outputPath};

  I received below error-

  Why is causing this error in above command ?Any help will be welcome.

• Adding fade in and out transition between the images while creating video from images with FFmpeg

  30 mai 2018, par BentCoder

  The command below creates a video out of unknown amount images and a background audio. I am looking a way to add fade in and out transition between the images. What should the command be in order to achieve this ?

  I have seen the examples in links below but sadly cannot implement it.

  • Create video with 5 images with fadeIn/out effect in ffmpeg
  • Slideshow with crossfading between the pictures

  Command

  ffmpeg \
  
    -pattern_type glob \
  
    -framerate 1/3 -i "/images/img-*.png" \
  
    -framerate 1/3 -loop 1 -t 5 -i "/images/background.png" \
  
    -i "/audios/audio.mp3" \
  
    -filter_complex \
  
      "[0:v]scale=854:480,setsar=1[v0]; \
  
       [1:v]scale=854:480,setsar=1[v1]; \
  
       [v0][v1]concat=n=2:v=1:a=0,format=yuv420p[v]" \
  
    -map "[v]" -map 2:a \
  
    -c:v libx264 \
  
    -c:a aac \
  
    -shortest \
  
    -movflags +faststart \
  
    "/output/video.mp4"

  If you wish the the the output, it is here.

  Note : If it helps, the size of my images and the names are all different. Some big some small and UUID names.

• How to restore a recorded mkv video back to its original state [closed]

  5 avril 2023, par itpotatoes

  The mkv video recorded with the Kinect camera was converted to mp4 after converting the color, depth, and ir video to avi using mkvtoolnix.
When I try to convert this back to avi with ffmpeg, it says that the depth and ir images cannot contain rawvideo gray16be in the avi container. Does anyone know of another way ?

  


  I could change it to another codec, but I couldn't convert it to rawvideo gray16be format.
