  • ffmpeg codec error on audio file

    31 juillet 2013, par foosion

    I have some m4a files that will not play properly using the google music player app on my Android phone, although they play fine on most everything else. I thought the problem was the container and thought "ffmpeg -i bad.m4a -codec copy good.m4a" might help. However, when I run on the problem files, I get error messages. Running this command on non-problem files has not generated error messages.

    Please suggest ways to fix (other than re-encoding).

  • flvEncoder .flv output won't convert to .mp4 with ffmpeg

    31 juillet 2013, par Emma Assin

    My current project involves creating a .flv using AIR (using https://github.com/zeropointnine/leelib/tree/master/src/leelib/util/flvEncoder) - which then has to be converted into an .mp4, for which we are using ffmpeg.

    The .mp4 output is the correct dimensions and duration, but blank (no images). Audio is not an issue as the original output has no audio.

  • Paperclip-ffmpeg not working on Rails

    28 juillet 2013, par Lee7355512727

    I installed Paperclip-ffmpeg and tried to upload a flv file, but it seems there are some problems converting the file.

    I added Paperclip.options[:command_path] = "/usr/bin/" (I got the path by using which ffmpeg) to my config/environments/development.rb file, following the instructions on the paperclip-ffmpeg github page.

    Here is my model subquestion.rb, which contains a paperclip field called qflv :

    class Subquestion < ActiveRecord::Base
    
    belongs_to :question
    
    has_many :qimages , :dependent =>  :destroy
    

    
    has_attached_file :qflv, styles: {
    
        medium: {geometry: "640*480", format: 'flv'},
    
        thumb: {geometry: "100*100#", format: 'jpg', time: 10}
    
    }, processors: [:ffmpeg]

    And here is my _subquestion_fields.html.erb file, where users upload videos :

    <%= f.file_field :qflv %>

    _subquestion_fields.html.erb is rendered by question.html.erb file :

    <%= nested_form_for @question, :url => {:action => 'create_question'} do |f| %>
    
       <%= f.fields_for :subquestions do |builder| %>
    
       <%= render 'subquestion_fields', :f => builder %>

    And here is part of the error message :

    There might be some problems with pkcs11 so I found this article :

    But I could not find /etc/xdg/autostart/gnome-keyring-*.desktop.
