• ffmpeg - Use filter in android

  12 décembre 2013, par kikuchi

  I'm trying to use the movie filter in my android project with ffmpeg. I use a fork of the guardian project : Cheers-dev

  It use a recent version of ffmpeg ( 15 days old atm). I added the option --enable-filter=movie to activate the filter.

  I use this command line in my android project :

  ffmpeg -i input.mp4 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]" -strict -2 outputvideo.mp4

  It perfectly works with my desktop version on Debian Wheezy. But it's impossible to make it work on my Android. All other commands works.

  Here the error when it fails : No such filter: 'movie'.

  I also tested with the option -filter_complex with a somewhat different error :

  $ ffmpeg -y -loglevel debug -i /storage/sdcard0/test/hsgjr_export.mp4 -i /storage/sdcard0/test/watermark.png -filter_complex "[0:v][1:v]overlay=main_w-overlay_w-10:main_h-overlay_h-10[out]" -map [out] -map 0:a -codec:a copy /storage/sdcard0/test/hsgjr_watermark.mp4

  The output is better than the previous one but I think I'm missing something.

  SOLUTION : I removed the quote from the filter_complex argument and it worked.

  Here is the working command :

  $ ffmpeg -y -i /storage/sdcard0/test/hsgjr_export.mp4 -i /storage/sdcard0/test/watermark.png -filter_complex [0:v][1:v]overlay=main_w-overlay_w-10:main_h-overlay_h-10[out] -map [out] -map 0:a -codec:a copy /storage/sdcard0/test/hsgjr_watermark.mp4

  Fix decoder mismatch with ssse3 enabled

  This patch fixed issue 661 : "Decoder produces mismatched outputs
  with ssse3 enabled and disabled." In sub-pixel filters, a pixel
  value was multiplied by a filter coefficient, and the results
  were added up. The order of adding up these multiplications had to
  be arranged carefully to prevent incorrect overflowing.
