• avformat/img2dec : add option to provide metadata fields related to input path

  1er janvier 2020, par Alexandre Heitor Schmidt

  avformat/img2dec : add option to provide metadata fields related to input path
  libavformat/img2.h : New field export_path_metadata to
  
  VideoDemuxData to only allow the use of the extra metadata
  
  upon explicit user request, for security reasons.
  libavformat/img2dec.c : Modify image2 demuxer to make available
  
  two special metadata entries called lavf.image2dec.source_path
  
  and lavf.image2dec.source_basename, which represents, respectively,
  
  the complete path to the source image for the current frame and
  
  the basename i.e. the file name related to the current frame.
  
  These can then be used by filters like drawtext and others. The
  
  metadata fields will only be available when explicitly enabled
  
  with image2 option -export_path_metadata 1.
  doc/demuxers.texi : Documented the new metadata fields available
  
  for image2 and how to use them.
  doc/filters.texi : Added an example on how to use the new metadata
  
  fields with drawtext filter, in order to plot the input file path
  
  to each output frame.
  Usage example :
  ffmpeg -f image2 -export_path_metadata 1 -pattern_type glob
  
   -framerate 18 -i '/path/to/input/files/*.jpg'
  
   -filter_complex drawtext="fontsize=40:fontcolor=white :
  
   fontfile=FreeSans.ttf:borderw=2:bordercolor=black :
  
   text='%metadata\:lavf.image2dec.source_basename\:NA':x=5:y=50"
  
   output.avi
  Fixes #2874.

  How give information about file with binary path /usr/bin/ffmpeg ?

  Peoples its not answer - its code for help all peoples-)

  Long time i search the correct code, now i write here. Washes it be useful to someone.

  1) get duration file

  ob_start();
  
  passthru("ffmpeg-9260.exe -i \"". $videofile . "\" 2>&1");
  
  $duration = ob_get_contents();
  
  ob_end_clean();
  
  
  
  
  
  preg_match('/Duration: (.*?),/', $duration, $matches);
  
  $duration = $matches[1];
  
  $duration_array = split(':', $duration);
  
  $duration = $duration_array[0] * 3600 + $duration_array[1] * 60 + $duration_array[2];
  
  $time = $duration * $percent / 100;
  
  $time = intval($time/3600) . ":" . intval(($time-(intval($time/3600)*3600))/60) . ":" . sprintf("%01.3f", ($time-(intval($time/60)*60)));

  2) get a picture of a particular frame of the video (flv or avi or another)

  ffmpeg -i video.avi -an -ss 00:01:30 -r 1 -vframes 1 -s 320×240 -y -f mjpeg screenshot.jpg

  3) how to convert video file to format .ogg

  a) ffmpeg -an -deinterlace -s 400×300 -r 20.00 -i CapeCodMarsh.avi -vcodec rawvideo -pix_fmt yuv420p -f rawvideo – |  ffmpeg -an -f rawvideo -s 400×300 -r 20.00 -i – -f yuv4mpegpipe – |  libtheora-1.0/lt-encoder_example –video-rate-target 512k – -o tmp.ogv
  
  
  
  b)ffmpeg -y -i CapeCodMarsh.avi -vn -acodec libvorbis -ac 2 -ab 128k -ar 44100 audio.ogg

  4) How I can get this value for the buffer ?

  var v = document.getElementById('file_id');
  
  var r = v.buffered.end(0);

  Enjoy=)
