• Need help concatenating multiple 2 part .mp4s

  9 septembre 2016, par Jay Ford7

  Basically, I have about 200 2-part videos that I would like to concatenate as 100 individual files.

  All the files are labeled with the same file name but with part 1 and part 2 on the end, ie "Video Name Part 1...Video Name Part 2"

  Through basic searching I understand how to combine two videos into one video manually with ffmpeg, but is there a way for ffmpeg to recognize the naming structure and do a batch concatenation ?

  EDIT : I should’ve said I was on Windows !

  Thanks !

• 400 Bad Request Error uploading paperclip videos

  5 mars 2017, par jalen201

  Im trying to upload videos with paperclip. When i hit the submit button i receive.

  RSolr::Error::Http - 400 Bad Request Error: 

  this is the migration

  class AddAttachmentVideoToPins < ActiveRecord::Migration
  
    def self.up
  
      change_table :pins do |t|
  
        t.attachment :video
  
      end
  
    end
  
  
  
    def self.down
  
      remove_attachment :pins, :video
  
    end
  
  end

  Heres the model

  class Pin < ApplicationRecord
  
    acts_as_votable
  
    belongs_to :user
  
    has_many :comments
  
  
  
    searchable do
  
      text :title, :boost => 5
  
      text :description
  
    end
  
  
  
    has_attached_file :image, styles: {medium: "300x300>" }
  
    validates_attachment_content_type :image, content_type: /\Aimage\/.*\z/
  
  
  
    has_attached_file :video, styles: {
  
      :medium => {
  
        :geometry => "640x480",
  
        :format => 'mp4'
  
      },
  
      :thumb => { 
  
        :geometry => "160x120", :format => 'jpeg', :time => 10 
  
      }
  
    },
  
    :processors => [:transcoder]
  
  
  
    validates_attachment_content_type :video, content_type:  /\Avideo\/.*\Z/

  also i added these 4 gems, and installed ffmpeg with homebrew

      gem 'paperclip', '~> 5.1'
  
  
  
      gem 'aws-sdk', '~> 2.8'
  
  
  
      gem 'paperclip-av-transcoder', '~> 0.6.4'
  
  
  
      gem 'paperclip-ffmpeg', '~> 1.2'

  lastly this is my controller, i added :video as a strong parameter.

  class PinsController < ApplicationController
  
  
  
    before_action :find_pin, only: [:show,:edit,:update,:destroy, :upvote]
  
    before_action :authenticate_user!, except: [:index,:show]
  
  
  
    def index
  
      @search = Pin.search do
  
        fulltext params[:search]
  
      end
  
      @pins = @search.results
  
    end
  
  
  
    def new
  
      @pin = current_user.pins.build
  
    end
  
  
  
    def show
  
      @comments = Comment.where(pin_id: @pin).order('created_at DESC')
  
    end
  
  
  
    def edit
  
      @lookup = User.all
  
    end
  
  
  
    def profile
  
      @users = User.all
  
      if User.find_by_username(params[:id])
  
        @username = params[:id]
  
        @user = User.find_by_username(params[:id])
  
      else
  
        redirect_to root_path
  
      end
  
      @user_pin = Pin.all.where('user_id = ?',       User.find_by_username(params[:id]).id)
  
    end
  
  
  
    def update
  
      if @pin.update(pin_params)
  
        redirect_to @pin, notice: "Pin was succesfully updated"
  
      else
  
        render 'edit'
  
      end
  
    end
  
  
  
    def destroy
  
      @pin.destroy
  
      redirect_to root_path       
  
    end
  
  
  
    def upvote
  
      @pin.upvote_by current_user
  
      redirect_to :back
  
    end
  
  
  
    def create
  
      @pin = current_user.pins.build (pin_params)
  
  
  
      if @pin.save
  
        redirect_to @pin , notice: "Succesfully created new pin"
  
      else
  
        render 'new'
  
      end
  
    end
  
  
  
    private
  
  
  
    def pin_params
  
      params.require(:pin).permit(:title, :description, :image, :video)
  
    end
  
  
  
    def find_pin
  
      @pin = Pin.find(params[:id])
  
    end
  
  end

  i added this in the view

  <%= video_tag @pin.video.url(:medium), controls: true, style: "max-width: 100%;" %>

  If anyone could help that would be greatly appreciated

• Ruby gem to transcode video on the fly

  28 novembre 2013, par Erick

  I am looking to create myself a little media server (read : little pet project for fun) at home.

  Is there any gem that would allow me to transcode on the fly and stream ?

  I know rvideo wraps ffmpeg but it's a one time thing. The only thing I could do is to transcode to a temp file and then stream that file. It doesn't sound like the idea solution.

  Anyone has done this in the past ?

  [edit] Looking to transcode anything (avi, xvid, divx, mkv, mpeg, flv) into mpeg4 to permit a normal html5 video player to do the job.
