• How to set header metadata to encoded video ?

  11 juin 2013, par Jona

  I'm encoding some images into an h264 video inside an mp4 container. I'm essentially using the ffmpeg example muxing.c. The thing is I'm trying to set some metadata in the mp4 container such as artist, title, etc...

  I thought using the following would work but it didn't :

  AVDictionary *opts = NULL;
  
  av_dict_set(&opts, "title", "Super Lucky Dude", 0);
  
  av_dict_set(&opts, "author", "Jacky Chan", 0);
  
  av_dict_set(&opts, "album", "Chinese Movie", 0);
  
  av_dict_set(&opts, "year", "05/10/2013", 0);
  
  av_dict_set(&opts, "comment", "This video was created using example app.", 0);
  
  av_dict_set(&opts, "genre", "Action", 0);
  
  
  
  // Write the stream header, if any.
  
  ret = avformat_write_header(oc, &opts);

  After the whole video is created I don't see any metadata written to the video file. Any pointers how to actually do this properly ?

• Concat videos with ffmpeg does not work [migrated]

  6 mai 2013, par Yannick Schinko

  I'm currently trying to concat 3 Videos which don't have a audio stream and adding a audio file in the same step.

  I created this command which should do the work :

  ffmpeg -y -r 30 -i data\intro.mp4 -vcodec ppm -f image2pipe -i data\render.ppm -i data\outro.mp4 -i "data\I could be the one.mp3" -c:v libx264 -crf 18 -preset slow -pix_fmt yuv420p -c:a copy -filter_complex "[0:0] [1:0] [2:0] concat=n=3:v=1:a=0 [v]" -map [v] -map 3:0 -shortest -metadata title="Development of BrainStoneMod" -metadata description="This is the development of the BrainStoneMod starting from 08th April, 2013" -metadata author="The_BrainStone" -metadata copyright="2013" -metadata year="2013" -metadata composer="" -metadata TBPM="" -metadata TDAT="" gource.mp4

  It is indeed a long command but it satisfied my needs until I wanted to embend the actual video in between a intro and a outro.

  I'm getting this log :

  What should I do ?

  By the way : This is the command I used before and worked out great :

  ffmpeg -y -r 30 -i "data\I could be the one.mp3" -vcodec ppm -f image2pipe -i data\render.ppm -c:v libx264 -crf 18 -preset slow -pix_fmt yuv420p -c:a copy -map 1:0 -map 0:0 -shortest -metadata title="Development of BrainStoneMod" -metadata description="This is the development of the BrainStoneMod starting from 08th April, 2013" -metadata author="The_BrainStone" -metadata copyright="2013" -metadata year="2013" -metadata composer="" -metadata TBPM="" -metadata TDAT="" gource.mp4

  Any ideas ?
