• Android FFmpeg : get frame count from video

  17 août 2017, par Tix

  I only want to filter out 20% of frames from the start of the video and the end of the video, but i cant do that if i dont have total frame count.

  I alr know how to filter out frames, i just need to know how to get total frame count of a video.

  I’ve looked this up, and there was answers saying use ffprobe to fetch total number of frames in a video. However ffmpeg for android doesnt have it.. is there another way to get the frame count from a video ?

  Compiled ffmpeg for android using :

  compile ’com.writingminds:FFmpegAndroid:0.3.2’

• where to put the watermark png file in this code ?

  15 août 2017, par asif

  this is a line from ffmpeg video converter php script ;

  $ffmpeg." -i ".$video_to_convert." -vcodec flv -f flv -r 30 -b ".$quality."-ab 128000 -ar".$audio." -s ".$size." ".$converted_vids.$name.".".$new_format."

  where :

  .$video_to_convert. = input file

  .$converted_vids.$name. = output file

  .$new_format. ; = file extention format

  now i want to add watermark.png file, if i put any where i got error conversion
  as i added the line logo.png -filter_complex 'overlay in video quality line, i got error

  Error ;
