• -shortest is not working while looping audio with amovie in FFMPEG

  18 juin 2019, par Nikunj Paradva

  Here input is two video total 40 second, i am concate that and speed up 4x,then video duration is 10 second,

  audio input duration is dynamic it ll be shorter than video or bigger than video duration that’s why i am using amovie command for replace audio with looping to infinite, and add -shortest command at last.

  but it won’t be worked. it goes to infinite process.

  Here is my command

  [-y,
  
   -i, /storage/emulated/0/Received/VID-20190407-WA0001.mp4,
  
   -i, /storage/emulated/0/Received/MP4_20190220_114210.mp4,
  
   -strict, experimental,
  
   -filter_complex, [0:v]scale=iw*min(480/iw\,480/ih):ih*min(480/iw\,480/ih), pad=480:480:(480-iw*min(480/iw\,480/ih))/2:(480-ih*min(480/iw\,480/ih))/2,setsar=1:1[v0];
  
                    [1:v]scale=iw*min(480/iw\,480/ih):ih*min(480/iw\,480/ih), pad=480:480:(480-iw*min(480/iw\,480/ih))/2:(480-ih*min(480/iw\,480/ih))/2,setsar=1:1[v1];
  
                    [v0][v1] concat=n=2:v=1[vTemp];[vTemp]setpts=0.25*PTS[finalv];
  
                    amovie=/storage/emulated/0/VideoEditor/.caches/Video_editor_1560762451434.mp3:loop=0,asetpts=N/SR/TB[aaa],
  
    -map, [finalv], -map, [aaa],
  
   -shortest, -preset, ultrafast,
  
   /storage/emulated/0/Video_1560762463583.mp4]

  here is logs of the process (logs going to infinity, but i added till stackoverflow limit)

• FFMPEG extracting 1 second resized with copy codec

  28 avril 2019, par boblapointe

  How can I extract 1 second ( using fast seek ) from a video, resize it, using vp9 ? I always get the same errors. Here are the bare bone commands I’m trying :

  ffmpeg -ss 00:00:10 -i test.webm -to 00:00:01 -filter:v "scale=min(iw\,1280):min(ih\,720):force_original_aspect_ratio=decrease" -c:v libvpx-vp9 -y output.webm

  It returns :

  "Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)

  After playing around I realize that this will work :

  ffmpeg -ss 00:00:10 -i test.webm -to 00:00:01 -c copy -y output.webm

  Not ideal but at least it works, so I add the filter :

  ffmpeg -ss 00:00:10 -i test.webm -to 00:00:01 -filter:v "scale=min(iw\,1280):min(ih\,720):force_original_aspect_ratio=decrease" -c copy -y output.webm

  Ant then I get :

  "Filtering and streamcopy cannot be used together."

  I’ve tried all kinds of combinations, unsuccessfully. Any hint would be appreciated. Thank you

• Video not clear when concatinate videos thogther using ffmpeg

  5 février 2018, par no name

  I have 3 types of the video first is start video played when the video start, the main video which is the main content of the video and last is the end video I want to add them together they have different resolutions so I use a text file to write the videos name like this.

  file start.mp4
  
  file main.mp4
  
  file end.mp4

  then I use this command with FFmpeg

  FFmpeg -f concat -i ffmpeg-sound.txt -c copy final_output.mp4

  the problem is when I start watching the video the first video image is appearing in all the video duration I tried different player every one shows me a crashed photo but the sound is working fine.
  also, the main video is created from mp3 file and image with subtitle it’s not original or downloaded from anywhere and I want to concatenate them.
  what i tried when i make some searches and i thought it’s the problem that they have different resolution so i tried this command on both 3 videos to make them have the same resolution so no problem show after the concatenate
  

  FFmpeg -y -i end.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts end.mp4.ts

  and try to add the 3 files again with ts formate and the same problem shown too so please any help to solve this
  Update
  i tried to use this command to change all the three videos to 1280x720

  FFmpeg -i a.mp4 -vf scale=1280:720 a1.mp4

  after testing the problem exactly i found that the first video only works then when it go to next video to show it, the screen is a freeze on the last image from the first video. I don’t know why this problem even after i make them same scale !
  here is the output of

  ffmpeg -i start.mp4 -i a.mp4 -i end.mp4

  output this before edit all the videos resulution to 1280x720
