• Adding audio to mp4 using ffmpeg at certain offset gives output file #0 does not contain any stream

  18 mai 2018, par Armand

  I am attempting to add audio to a MP4 file using ffmpeg at a specific time, eventually I also want the audio to only play until a certain point, so if you can help with that also that would be great, otherwise if you can just assist me in figuring out what is causing this error.

  The arguments I use

  -y "E:\Documents\Content Bar/Photo Booth\PhotosDrop\2018-05-15 14-01-16OUT.mp4" -itsoffset  -i "E:\Downloads\wetransfer-250b26\05 Call of Love.mp3" -map 0:0 -map 1:0 -c:v copy -shortest "E:\Documents\Content Bar\Photo Booth\PhotosDrop\2018-05-15 14-01-16OUTOUT.mp4"

  This results in the following error :

• FFmpeg : why we need to create temp files during conversion

  29 mars 2019, par Awais fiaz

  I have been studying about ffmpeg, its properties and its usage. I have started using a pre-made PHP based script which creates temp files during conversion. I am trying to figure out what it actually does in this given command. Why is this command creating temp files during conversion and what is the purpose of it ?

  /usr/bin/ffmpeg -y -i /var/www/html/conversion_server/files/conversion_queue/15270581986ece98.mp4 -f mp4  -vcodec libx264 -preset superfast -r 23.97598565277  -maxrate 320000 -g 60 -crf 29 -profile:v baseline  -s 426x240 -aspect 1.77  -acodec libfdk_aac -ab 320k -ar 44100  /var/www/html/conversion_server/files/videos/2018/05/23/15270581986ece98/15270581986ece98-240.mp4 2> /var/www/html/conversion_server/files/temp/1527058199834e4.tmp

  Any help regarding this would be really appreciated.

• Command for putting watermark on video

  28 juin 2018, par Yupi

  I tried to put watermark on one video but FFmpeg command won’t execute and error code is 3037. I run the same code for trimming video and video is trimmed successfully so there is no issues with inputpath or outputpath also I have ic_watermark.png in assets folder. I tried with image from Drawable but same error code.

  So here is the command which I tried to run and put watermark in right corner :

  String[] cmd = new String[]{"-i", videoInputPath, "-i", imagePath, "-filter_complex", "overlay=main_w-overlay_w-5:main_h-overlay_h-5", videoOutPath };

  and this is the whole method :

  private void executeFFmepg(String inputPath, String outputPath, String customCommand){
  
  final Command command = videoKit.createCommand()
  
          .overwriteOutput()
  
          .inputPath(inputPath)
  
          .outputPath(outputPath)
  
          .customCommand(customCommand)
  
          .experimentalFlag()
  
          .build();
  
   new AsyncCommandExecutor(command, this).execute(); 
  
   }

  I used one library based on FFmpeg : https://github.com/inFullMobile/videokit-ffmpeg-android
  and description says that this is basically invoking FFmpeg main() with CLI arguments.

  This is what I get from Log :

  I tried many answers from similar questions but none of them worked.

  Is possible that error is in quotes ?

  I don’t have experience with FFmpeg so any help would be very appreciated. Thanks
