• ffmpeg and the 'unable to find suitable output' error

  6 mars 2016, par Ahmet Oğruz

  I want to add an image to a video using ffmpeg as below ;

  ffmpeg -i input.avi -vf "movie=file.png [watermark]; [in][watermark] overlay=10:10 [out]" output.flv
  
  
  
   Runtime.getRuntime().exec("C:\\FFMPEG\\bin/ffmpeg -i D:\\contents\\DoubleKnockout\\videos\\1.mp4 -vf \"movie=D:\\contents\\tall.png  [watermark]; [in][watermark] overlay=10:10 [out]\" D:\\contents\\resultpng.mp4");  

  But I got

   Unable to find a suitable output format

  Any idea what’s going on ?

• How do I run the qt ffmpeg wrapper example ? (error : cannot find -lavutil)

  29 août 2013, par James

  I am using QT 4.8 on the raspberry pi trying to save a binary stream to a video file like mp4. I was able to create and save static images by converting it into a QImage, but QT does not seem to support actually saving that stream (or the series of QImages) to a video file.

  The only option I may have found is qt ffmpeg Wrapper
  https://code.google.com/p/qtffmpegwrapper/

  but the example won't run out of the box. I am having the same exact problem as this guy :

  https://code.google.com/p/qtffmpegwrapper/issues/detail?id=14&colspec=ID%20Type%20Status%20Priority%20Milestone%20Owner%20Summary%20Opened%20Closed%20Modified#makechanges

  All I did was download it and try to run the included example, but no go.
  Am I supposed to download ffmpeg files prior to using this ? apt-get install ffmpeg ?

  Thanks !
