• Revision 103307 : - Les plugins-dist de spip 3.2 ne sont pas supposé avoir de support pour ...

  17 mars 2017, par spip.franck@… — Log

   Les plugins-dist de spip 3.2 ne sont pas supposé avoir de support pour qu’il fonctionne avec spip 3.1, donc, j’ai fait un z+1 quand il y avait déjà un "y" de différence entre spip 3.1 et 3.2 sinon, j’ai fait un y+1, ainsi il sera toujours possible de faire des corrections d’éventuel bugs future qui ne concernerait que les plugs de la version 3.1
   La version de mini de compatibilité est maintenant 3.2.0-dev, comme, ça, quand l’alpha sortira, cela devrait être bon (quand la version 3.2.0 stable sortira, je mettrais 3.2.0 comme version mini)
   Il y avait aussi un ou deux mots avec des accents comme par exemple &amp ;#232 ; j’ai fait le changement pour y mettre à la place è ou autres

• Adding mp3 metadata with space in ffmpeg using bash [duplicate]

  This question already has an answer here :

  • When to wrap quotes around a shell variable ?

  I have this bash script on downloading youtube videos then convert it to mp3 using youtube-dl and ffmpeg.

  #!/bin/bash
  
  
  
  ytlink=""
  
  outputFileName=""
  
  title=""
  
  artist=""
  
  album=""
  
  
  
  while getopts l:o:t:r:b: flag; do
  
    case "${flag}" in
  
      l) ytlink="${OPTARG}";;
  
      o) outputFileName="${OPTARG}";;
  
      t) title="${OPTARG}";;
  
      r) artist="${OPTARG}";;
  
      b) album="${OPTARG}";;
  
    esac
  
  done
  
  
  
  youtube-dl "$ytlink" --add-metadata --extract-audio --audio-format mp3 --output "temp.%(ext)s"
  
  
  
  tempFilename="temp.mp3"
  
  outputFileName="$outputFileName.mp3"
  
  
  
  args+=("-i" "$tempFilename" "-metadata" "title='$title'" "-metadata" "artist='$artist'" "-metadata" "album='$album'" "-metadata" "comment=Source:$ytlink")
  
  ffmpeg -loglevel debug ${args[@]} -acodec copy "$outputFileName"
  
  rm "$tempFilename"

  This script is fine if I have one word title/artist/album. However, if I have a space, ffmpeg interprets each word before space as another parameter. This is how I use this on command line :

  ./yttomp3.sh -l "https://www.youtube.com/watch?v=KwQnSHAilOQ" -o "Lee - Autumn Day" -t "Autumn Day" -r "Lee" -b "(Free) Lo-fi Type Beat - Autumn Day"

  The debug output of ffmpeg :

  Splitting the commandline.
  
  Reading option '-loglevel' ... matched as option 'loglevel' (set logging level) with argument 'debug'.
  
  Reading option '-i' ... matched as input url with argument 'temp.mp3'.
  
  Reading option '-metadata' ... matched as option 'metadata' (add metadata) with argument 'title='Autumn'.
  
  Reading option 'Day'' ... matched as output url.
  
  Reading option '-metadata' ... matched as option 'metadata' (add metadata) with argument 'artist='Lee''.
  
  Reading option '-metadata' ... matched as option 'metadata' (add metadata) with argument 'album='(Free)'.
  
  Reading option 'Lo-fi' ... matched as output url.
  
  Reading option 'Type' ... matched as output url.
  
  Reading option 'Beat' ... matched as output url.
  
  Reading option '-' ... matched as output url.
  
  Reading option 'Autumn' ... matched as output url.
  
  Reading option 'Day'' ... matched as output url.
  
  Reading option '-metadata' ... matched as option 'metadata' (add metadata) with argument 'comment=Source:https://www.youtube.com/watch?v=KwQnSHAilOQ'.
  
  Reading option '-acodec' ... matched as option 'acodec' (force audio codec ('copy' to copy stream)) with argument 'copy'.
  
  Reading option 'Lee - Autumn Day.mp3' ... matched as output url.
  
  Finished splitting the commandline.

  I tried enclosing the arguments to quotes on the script but it’s still not working. How should I deal with this ? Thanks.

• ERROR : Cannot Autodetect input stream or No signal

  23 juin 2022, par Damián Devera

  I am using Decklink Mini Recorder to capture video (it has SDI and HDMI inputs, tried both).

  


  This is my setup : Debian 10.2.1 (non GUI), ffmpeg 5.0, Blackmagic software 12.3

  


  For that I installed custom build of ffmpeg :

  


  sudo apt-get update -qq && sudo apt-get -y install \
  autoconf \
  automake \
  build-essential \
  cmake \
  git-core \
  libass-dev \
  libmp3lame-dev \
  libfreetype6-dev \
  libtool \
  libvorbis-dev \
  pkg-config \
  texinfo \
  wget \
  zlib1g-dev
sudo apt-get -y install \
  nasm yasm

sudo apt-get install -y libopus-dev
sudo apt-get install -y libvpx-dev
sudo apt-get install -y libx264-dev
sudo apt-get install -y libx265-dev
sudo apt-get install -y libnuma-dev
sudo apt-get install -y libfdk-aac-dev
sudo apt-get install -y libmp3lame-dev

cd ~/ffmpeg_sources && \
git -C fdk-aac pull 2> /dev/null || git clone --depth 1 https://github.com/mstorsjo/fdk-aac && \
cd fdk-aac && \
autoreconf -fiv && \
./configure --prefix="$HOME/ffmpeg_build" --disable-shared && \
make && \
make install



cd ~/ffmpeg_sources

sudo cp ffmpeg ffprobe /usr/local/bin/


  


  I can see my card using Blackmagic softwares for the card and also using ffmpeg -sources decklink.

  


  But when I try to run this : ffmpeg -f decklink -i 'DeckLink Mini Recorder' -t 10 -c:v libx264 -f mp4 test.mp4

  


  I get error : Cannot Autodetect input stream or No signal  DeckLink Mini Recorder: Input/output error

  


  UPDATE 1 : I used new command ffmpeg -y -format_code 23ps -f decklink -i 'DeckLink Mini Recorder' test.mov -report
Now I can run command, but I capture only colour bars.

  


  UPDATE 2 : I used new command ffmpeg -f decklink -video_input hdmi -i ‘DeckLink Mini Recorder’ -t 10 test.mp4
I am now capturing over HDMI.

  


  Now I am trying to use SDI on the card (which is my main target) but running into same problems (using this command : ffmpeg -f decklink -video_input sdi -i ‘DeckLink Mini Recorder’ -t 10 test.mp4). I have HDMI to SDI convertor from BlackMagic (HDMI to SDI 3G). Does anybody know, what is the problem ?
