reduce bitrate using ffmpeg
27 mai 2017, par WantItI 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 :

Uploading videos on rails website
16 mai 2017, par DinukapereraI am trying to let my users upload videos on my website(not deployed yet, testing locally). I have it set up in a manner where if the "user information" gets saved, it will take them to the "root_path", which is the homepage. If the user information is not saved, it will render the form again. Before I added the video upload feature, all the information got saved and everything worked well, but after adding the feature, it keeps rendering the same form over and over again since the information is not getting saved. How do I check what’s wrong ? The command line gives me this error :
The user information form partial :
`<%= simple_form_for @userinfo do |f| %>
<%= f.input :name, label: 'Full name', error: 'Full name is mandatory' %>
<%= f.input :username, label: 'Username', error: 'Username is mandatory, please specify one' %>
<%= f.input :school, label: 'Name of college' %>
<%= f.input :gpa, label: 'Enter GPA' %>
<%= f.input :email, label: 'Enter email address' %>
<%= f.input :number, label: 'Phone number' %>
<%= f.file_field :video %>
<%= f.button :submit %>
<% end %>`
My user controller (This is the user information controller, does not control user email and password. I’m using the devise gem for user sign in, sign out, and sign up) :`
class UsersController < ApplicationController
def index
end
def show
end
def new
@userinfo = User.new
end
def create
@userinfo = User.new(user_params)
if @userinfo.save
redirect_to root_path
else
render 'new'
end
end
def edit
end
def update
end
def destroy
end
private
def user_params
params.require(:user).permit(:name, :username, :email, :number, :school, :gpa, :major, :video)
end
end`
This is the user model (usermain is the model related to user password and email. The user information in the user model belongs to the usermain) : `
class User < ActiveRecord::Base
belongs_to :usermain
has_attached_file :video, styles: {:video_show => {:geometry => "640x480",:format => 'mp4'},:video_index => { :geometry => "160x120", :format => 'jpeg', :time => 10}}, :processors => [:transcoder]
validates_attachment_content_type :video, content_type: /\Avideo\/.*\Z/
end`
This is the migration file that creates the user information table :`
class CreateUsers < ActiveRecord::Migration
def change
create_table :users do |t|
t.string :name
t.string :username
t.string :email
t.string :number
t.string :school
t.string :gpa
t.string :major
t.timestamps null: false
end
end
endThis is adding the "video" field to the above created user information table:
class AddAttachmentVideoToUsers < ActiveRecord::Migration
def self.up
change_table :users do |t|
t.attachment :video
end
end
def self.down
remove_attachment :users, :video
end
end`
I also have paperclip and ffmpeg installed. When I say installed, it’s literally just that. I’m not sure if I have to manipulate paperclip or ffmpeg in any way to make it work with the videos, I have just installed and did nothing else with them. I have been pulling my hair out for the past two days. Any help is appreciated.
