  11 mai 2018, par Adnan Khan

  Want to concatenate two audio files. i used an npm package known as audioconcat but when i installed and configured the below code i am confronted with the following error

  Error: Error: Cannot find ffmpeg

• getting 2 video streams in output.mkv ?

  3 janvier 2024, par Kirito

  In short, I have 1 video.mkv and 1 subtitle.ass. Using ffmpeg, I am adding subtitles to the video without removing the previous subtitles that came with the video. The problem is that some videos' output.mkv files are getting a duplicate video stream. Not all the videos I tested have this issue. I have added the log of one of those for reference.

  


  Here is my code :

  


   ffmpeg -i input_video.mkv -i subtitle_path.ass -c:v copy -c:a copy -c:s copy -map 0:v:0
 -map 0:m:language:jpn -map 0:s -map 1 -metadata:s:s:3 language=ara -max_interleave_delta 0 -y output_path.mkv


  


  \TEST> ffmpeg -i input_video.mkv -i subtitle_path.ass -c:v copy -c:a copy -c:s copy -map 0:v:0 -map 0:m:language:jpn -map 0:s -map 1 -metadata:s:s:3 language=ara -max_interleave_delta 0 -y output_path.mkv
