• Getting 500 error when uploading video to twitter from android app

  11 juillet 2016, par Sakshi

  I am trying to compress video using FFMPEGAndroid library using the following command.

  {"-y" ,"-i", file.getAbsolutePath(),
  
  "-c:v", "libx264", "-crf", "20",
  
  "-aspect", "1:1",
  
  "-pix_fmt", "yuv420p",
  
  "-c:a", "aac", "-strict","experimental",
  
  "-b:a", "96k", "-ac", "2", "-ar", "44100",
  
  "-preset", "ultrafast",
  
  "/storage/emulated/0/output.mp4"}

  When I try to share the video on Twitter from my android app, I get 500 Internal Server Error. I am able to share same video on Facebook and on my app. I have been read a lot of forums and FFMPEG manuals but no luck.

• At least one output file must be specified

  11 mai 2015, par Desipicforu Blogspot

  I am using this command in ffmpeg

     ffmpeg -i test.flv -i /var/www/phpvibe/logo.gif -filter_complex "scale=1200:-1,overlay=0:0" -s 1280x720 -vcodec libx264 -s 640x360 -movflags test.mp4 2>&1

  But i am getting this

   string(42) "At least one output file must be specified"

  updated :-

  php code :-

   $output ='{ffmpeg-cmd} -i {input} -i /var/www/phpvibe/logo.gif -filter_complex "scale=1200:-1,overlay=0:0" -s 1280x720 -vcodec libx264 -s {ffmpeg-vsize} -threads 4 -movflags {output}.mp4 2>&1';
