  • De l’upload à la vidéo finale [version standalone]

    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
    Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

  • Rails using stremio-ffmpeg gem to watermark a movie while uploading

    16 juin 2016, par Felix

    I am using carrierwave to upload a movie to amazon s3 that works perfect.

    Now I want to add a watermark to the movie while uploading or after uploading, I don’t know, what’s the best way ?

    I tried this :

    movie_controller.rb action uploadVideo

    movie = FFMPEG::Movie.new(@vid.video.url)
    

    
puts "........................................"
    
puts movie.inspect
    

    
if @vid.save

    Just to find out if the video is catched from stremio.

    But then I got the error that the movie is not found, the problem is that it doesn’t look in the amazon s3 bucket, it looks on my local server

    No such file or directory - the file '/uploads/tmp/1462954331-3471-8766/VID-20160424-WA0013.mp4' does not exist

    What could be the solution ? or should I do this in carrierwave uploader ?

    UPDATE :

    When I do this after the .save action it looks at amazon s3 bucket .. but also says that the movie isn’t there. But if I call it directly in browser it’s displayed.

    UPDATE Code :

    #Laedt ein Video hoch
    
def uploadMovie
    
  @user = User.find_by_id session[:user_id]
    
  #Holt alle Channels für die er eine Berechtigung hat (Eingeloggter user)
    
  @user = User.find_by_id session[:user_id]
    
  @knowledgeproviderList = @user.knowledgeprovider
    
  @channels = Channel.where(knowledgeprovider_id:     @knowledgeproviderList.pluck(:id))
    
  @vid = Movie.new(movies_params)
    
  @channel = Channel.find(params[:vid][:channel_id])
    
  @vid.channel = @channel
    

    
  #Fügt dem Movie einen Tag hinzu
    
  createTag params
    
  createCategory params
    

    

    

    
  if @vid.save
    
    flash[:notice] = t("flash.saved")
    

    
    #movie = FFMPEG::Movie.new(@vid.video.url)
    

    
    #puts "........................................"
    
    #puts movie.inspect
    

    
    redirect_to :action => :add
    
   else
    
     redirect_to :action => :add
    
  end
    
 end

    Update error :

    movie = FFMPEG::Movie.new(@vid.video.current_path)
    

    
options = {watermark: "mages/header.png", resolution: "640x360", watermark_filter: { position: "RT", padding_x: 10, padding_y: 10 } }
    
movie.transcode("movie.flv", options)

    enter image description here

    Update :
    Added the code in the uploader :

      process :watermark_movie
    

    
     def watermark_movie
    
       if self.file.path
    
             options = {watermark: "images/header.png", resolution: "640x360", watermark_filter: { position: "RT", padding_x: 10, padding_y: 10 } }
    
             self.model.file = FFMPEG::Movie.new(self.file.path).transcode("#{root}/#{cache_dir}/#{self.cache_id}/file.mp4", options)
    
        end
    
      end

    I'm following this guide http://trac.ffmpeg.org/wiki/CompilationGuide/Centos to first install the dependencies and compile the package.

  • 'C' program to pipeout audio file to FFMPEG and generate Video file

    9 mai 2017, par soflow

    I am attempting to write a short ’C’ program which reads in an Audio file using FFMPEG, processes that file using a ’C’ program, and then outputs a file via FFMEPG, which combines the new, modified audio together with a Video representation using the FFMPEG showwaves filter.

    At present the program attempts to do the following :-

    i) Read in an audio file, using pipein thorugh FFMPEG
    ii) Process the audio file using a portion of the ’C’ program
    iii) Pipeout the modified audio to FFMPEG, and generate a file using the ’showwaves’ filter in FFMEPG to create an MP4 file with audio and video.

    The following code run form the ommand line in FFMPEG generates the Audio/Video MP4 I want to create :-

    ffmpeg -y -f s16le -ar 44100 -ac 1 -i 12345678.wav  -i 12345678.wav  -filter_complex  "[0:a]showwaves=s=1280x720:mode=line:rate=25,format=yuv420p[v]" -map "[v]" -map 1:a:0 -codec:v libx264 -crf 21 -bf 2 -flags +cgop -pix_fmt yuv420p -codec:a aac -strict -2 -b:a 384k -r:a 48000 -movflags faststart  12345678.mp4

    "

    This code generates a processed audio file, and outputs it to a .wav file as required :-

    #include 
    
#include 
    
#include 
    

    
void main()
    
{
    
// Launch two instances of FFmpeg, one to read the original WAV
    
// file and another to write the modified WAV file. In each case,
    
// data passes between this program and FFmpeg through a pipe.
    
FILE *pipein;
    
FILE *pipeout;
    
pipein  = popen("ffmpeg -i 12345678.wav -f s16le -ac 1 -", "r");
    
pipeout = popen("ffmpeg -y -f s16le -ar 44100 -ac 1 -i - out.wav", "w");
    

    
// Read, modify and write one sample at a time
    
int16_t sample;
    
int count, n=0;
    
while(1)
    
{
    
    count = fread(&sample, 2, 1, pipein); // read one 2-byte sample
    
    if (count != 1) break;
    
    ++n;
    
    sample = sample * sin(n * 5.0 * 2*M_PI / 44100.0);
    
    fwrite(&sample, 2, 1, pipeout);
    
}
    

    
// Close input and output pipes
    
pclose(pipein);    
    
pclose(pipeout);
    
}

    (This code borrowed from ted Burke’s excellent post here)

    I have made an attempt as shown below, but this is not working :-

    #include 
    
#include 
    
#include 
    

    
void main()
    
{
    
// Launch two instances of FFmpeg, one to read the original WAV

    Ideally someone can suggest an improved version of the pipeout command above - alternately another process to achieve this would be interesting

    * EDIT *

    Thanks to @Mulvya, the revised pipeout line is now :-

    pipeout = popen("ffmpeg -y -f s16le -ar 44100 -ac 1 -i -  -filter_complex  "[0:a]showwaves=s=1280x720:mode=line:rate=25,format=yuv420p[v]" -map "[v]" -map 1:a:0 -codec:v libx264 -crf 21 -bf 2 -flags +cgop -pix_fmt yuv420p -codec:a aac -strict -2 -b:a 384k -r:a 48000 -movflags faststart  12345678.mp4

    ", "w") ;

    On compiling with gcc I get the following error messages :-
