• Compiling ffmpeg only for converting images to video(w/ sound)

  14 décembre 2012, par digvijay91

  Ok, so I have successfully compiled ffmpeg for android using the Guardian Project source code. Now the binary comes out around 10 MB. But since it has to goto a phone, i just wanted it to be as small as possible.
  Now The Guardian Project code has a file configure_ffmpeg.sh(goto link to see) which it says to change to add/remove functionality. But i have no clue what does what. So could some help me out sorting this. Ideally I would be able to disable a few things.

  Thanks,

• Trying to merge wav with video file using ffmpeg

  12 août 2023, par bat_cmd

  This batch file isn't working and I know the ffmpeg commands work when the command is on its own.

  


  I am using a WAV file that's exactly the length of the video (it was extracted from the video I am trying to add it back to).

  


  The NOAUDIO and NOVIDEO labels work properly if I delete the wav and/or video file from the folder where ffmpeg.exe and the batch file are.

  


  When the batch file is run with a wav audio and mp4 video file there, it just flashes up a command window. I tried putting pause after every single command but, still no joy.

  


  Is there a mistake here somewhere ?

  


  Cheers folks...

  I just tested this and it does work, using the exact same commands as in the above batch file just with all the labels removed...

  


  For %%a IN ("*.wav") DO Set FILEWAV=%%~na

:MP4FILE
For %%a IN ("*.mp4") DO Set FILEMP4=%%~na
start /wait ffmpeg.exe -i "%FILEMP4%.mp4" -i "%FILEWAV%.wav" -c:v copy -map 0:v:0 -map 1:a:0 "%FILEMP4%-NEW.mp4"
goto FINISHED

:FINISHED
exit


  


  So I know the reason it's not working is something to do with the order the batch file runs. It's odd because I have another batch file just like it for extracting the WAV in the first place and that does work, with labels set out just like the first batch file above. Perplexing.

  


  If I reduce it to just this, it works...

  


  For %%a IN ("*.wav") DO Set FILEWAV=%%~na

For %%a IN ("*.avi") DO Set FILEAVI=%%~na
start /wait ffmpeg.exe -i "%FILEAVI%.avi" -i "%FILEWAV%.wav" -c:v copy -map 0:v:0 -map 1:a:0 "%FILEAVI%-NEW.mp4"

For %%a IN ("*.mp4") DO Set FILEMP4=%%~na
start /wait ffmpeg.exe -i "%FILEMP4%.mp4" -i "%FILEWAV%.wav" -c:v copy -map 0:v:0 -map 1:a:0 "%FILEMP4%-NEW.mp4"

For %%a IN ("*.webm") DO Set FILEWEBM=%%~na
start /wait ffmpeg.exe -i "%FILEWEBM%.webm" -i "%FILEWAV%.wav" -c:v copy -map 0:v:0 -map 1:a:0 "%FILEWEBM%-NEW.mp4"

For %%a IN ("*.mkv") DO Set FILEMKV=%%~na
start /wait ffmpeg.exe -i "%FILEMKV%.mkv" -i "%FILEWAV%.wav" -c:v copy -map 0:v:0 -map 1:a:0 "%FILEMKV%-NEW.mp4"

exit
