  • reduce bitrate using ffmpeg

    21 mai 2017, par WantIt

    I have this command to run with ffmpeg to reduce bitrate.

    ffmpeg -y -i input.mp4 -b:v 1024k output_1024k.mp4

    where we want to take the input file and just reduced it’s bitrate (just 1024k). It works in the commandline.
    Now, I like to reduce bitrate via Java. I decided to use bytedeco/javacv FFmpegFrameGrabber and FFmpegFrameRecorder to perform the same function. Below is my code :

    FFmpegFrameGrabber grabber = new FFmpegFrameGrabber("input.mp4");
    
            grabber.start();
    

    
            FrameRecorder recorder = new FFmpegFrameRecorder("out.mp4", grabber.getAudioChannels());
    
            recorder.setSampleRate(256);
    
            recorder.start();
    

    
            Frame frame;
    
            while ((frame = grabber.grabFrame()) != null) {
    
                recorder.record(frame);
    
            }
    
            recorder.stop();
    
            grabber.stop();

    but it is saying the following error :

  • Video upload with carrierwave-video on Rails 4

    15 juin 2017, par MJRLGUE

    it’s been a while I am fighting to play a video in my rails app.

    I am using carrierwave-video, OS : Windows 10 64bits, to stream/show a video in user posts.

    Here is what I did :

    the file video_uploader.rb :

    class VideoUploader < CarrierWave::Uploader::Base
    

    
  include CarrierWave::Video
    
  storage :file
    
  def store_dir
    
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
    
  end
    
end

    in the file : _post.html.erb :

    with this line of code : <%= video_tag post.video_url :controls =>true %> I get a blank box with the size of the video.
    and I tried this too and still doesn’t work : <%= video_tag post.video.url if post.video? %>

    I tried ffmpeg too, I installed ffmpeg in my pc and I did include : process encode_video: [:mp4, callbacks: { after_transcode: :set_success } ] in video_uploader.rb file and I get this form error message :

    Video Failed to transcode with FFmpeg. Check ffmpeg install and verify
    video is not corrupt or cut short. Original error : ArgumentError

    Any suggestions please ?
