• ffmpeg does not copy custom metadata

  20 juin 2015, par e110c0

  I’m trying to fix some videos made with an iDevice. The videos have a rotation in the metadata which is only understood by Apple and its software but noone else. Fixing this is quite simple, but I also would like to keep the other metadata in the files like the geolocation.

  I tried a couple of versions, all with the same result, e.g. :

  ffmpeg -i input.mov -vf vflip,hflip -map_metadata 0 -metadata:s:v:0 rotate=0  -acodec copy output.mp4

  This should work, it already gives the correct preview of metadata :

  I also tried to add the one tag I’m interested in by hand with

  -metadata:g location=+48.2683+007.7205+172.710/

  with no change in the result.

  Output as .mov doesn’t change anything, neither.

  Is there any trick to add non-standard metadata ? How do I get the location back in there ?

  Thanks in advance to anyone who can give some insight on this.

• compile ffmpeg with alsa support on Ubuntu 12.04 amd64

  6 octobre 2015, par user1129812

  I had followed the ffmpeg compile instructions described in "CompilationGuide/Ubuntu – FFmpeg" and had successfully compiled a version of ffmpeg on my Ubuntu 12.04 amd64 system. This compiled version of ffmpeg works ok for my normal usage. However, recently, I want to grab my Ubuntu desktop with sound from applications, I follow the instructions in "HOWTO : Proper Screencasting on Linux" and I use the command :

  ~/bin/ffmpeg -f alsa -ac 2 -i hw:0 -f x11grab -r 30 -s 1024x768 -i :0.0 -acodec pcm_s16le -vcodec libx264 -preset ultrafast -crf 0 -threads 0 out_video_test.mkv

  to want to grab my Ubuntu desktop with sound from application. The terminal output from this command is :

  The video part is grabbed ok but there is no sound in the output video. I had followed the procedures described in the FAQ in "HOWTO : Proper Screencasting on Linux" to use "pavucontrol" to set "capture application audio instead of mic". However, I still could only grab video from my Ubuntu desktop.

  I find that I have installed libasound2-dev in my Ubuntu 12.04 amd64 system. The "libasound.so" file is in /usr/lib/x86_64-linux-gnu while the "asoundlib.h" file is in /usr/include/alsa. The config options when I compile ffmpeg is :

  PATH="$PATH:$HOME/bin" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure 
  
    --prefix="$HOME/ffmpeg_build" 
  
    --extra-cflags="-I$HOME/ffmpeg_build/include"

    --enable-libvpx 
  
    --enable-libx264 
  
    --enable-nonfree 
  
    --enable-x11grab

  I want to know that how do I find out whether I have compiled the alsa support into my ffmpeg ? Do I need to add the ffmpeg config option

  --extra-libs=-lasound

  to get alsa support when compiling ffmpeg ? (as described in some discussions in the internet) If yes, how do I specify the paths of "libasound.so" and "asoundlib.h" so that they would be used in the ffmpeg compilation process ?

  Moreover, if alsa support is already compiled in my ffmpeg, what else should I try so as to be able to grab sound from application using my ffmpeg ?

  Any idea. Thanks for any suggestion.

• ffmpeg doesn't correctly work with mkv

  26 avril 2017, par Alex

  Now I’m trying to trim mkv file with ffmpeg command.

  ffmpeg -y -i 1.mkv -filter_complex "[0:0]trim=start=201:duration=28,setpts=PTS-STARTPTS" a.mp4

  after processing a.mp4 is created with length(28s), but there is problems.

  1. Video is some flapped while playing.
  2. Audio is continued though playing has ended beyond 28s.

  So could you guys tell me what can I do ?

  When ffmpeg processing, it shows some errors as like this :
