• How to encode video with ffmpeg for playback on Android ?

  3 janvier 2012, par Sean

  I've got a c++ library that is encoding video in realtime from webcams to mp4 files (H264). The settings i've got are as follows :

      codecContex->profile=FF_PROFILE_H264_BASELINE; //Baseline
  
      codecContex->gop_size=250;
  
      codecContex->max_b_frames=0;
  
      codecContex->max_qdiff=4;
  
      codecContex->me_method=libffmpeg::ME_HEX;
  
      codecContex->me_range=16;
  
      codecContex->qmin=10;
  
      codecContex->qmax=51;
  
      codecContex->qcompress=0.6;
  
      codecContex->keyint_min=10;
  
      codecContex->trellis=0;
  
      codecContex->level=13; //Level 1.3
  
      codecContex->weighted_p_pred = 2;
  
      codecContex->flags2|=CODEC_FLAG2_WPRED+CODEC_FLAG2_8X8DCT;

  This creates MP4 files that play on iOS devices and on Windows Phone 7 devices but not on Android devices. I've read that Android only supports movies encoded with the baseline profile. These settings should produce a baseline movie but when I look at the generated MP4 file with MediaInfo it says it's AVC(High@L1.3). This might be why it's not working but I can't seem to get it to generate something with AVC(Baseline@L1.3)...

  If I remove the last line :

  codecContex->flags2|=CODEC_FLAG2_WPRED+CODEC_FLAG2_8X8DCT;

  Then MediaInfo reports the file as being "AVC(Main@L1.3)" instead - but those flags are part of the Baseline profile !

• How do I get videos to upload using ruby on rails carrierwave-video ?

  9 juillet 2016, par Eric

  Updated as of July 9, 2016

  I tried to follow the instructions on the github website for the video uploader process using carrierwave-video gem but get an error that says the file or directory mmpeg -i doesn’t exist.

  The upload path for images functions correctly, just not the video one.

  I have added all of the following code necessary to help solve the error and minified as much as i possibly could.

  Video uploader code using carrierwave

  class VideoUploader < CarrierWave::Uploader::Base

    include CarrierWave::Video
  
    storage :file
  
  
  
    version :mp4 do
  
      process :encode_video => [:mp4, resolution: "100x100"]
  
    end
  
  
  
    def store_dir
  
      "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  
    end
  
  end

  Here is the movie controller code that handles uploading of videos

  class MoviesController < ApplicationController
  
     include MoviesHelper
  
  
  
     def index
  
        mode "index"
  
     end
  
  
  
     def show
  
        mode "show"
  
     end
  
  
  
     def new
  
        mode "new"
  
     end
  
  
  
     def edit
  
        mode "edit"
  
     end
  
  
  
     def create
  
        mode "create"
  
     end
  
  
  
     def update
  
        mode "update"
  
     end
  
  
  
     def destroy
  
        mode "destroy"
  
     end
  
  
  
     def review
  
        mode "review"
  
     end
  
  
  
     def approve
  
        mode "approve"
  
     end
  
  
  
     def deny
  
        mode "deny"
  
     end
  
  end

  Here is the model data for the movie that goes with it

  class Movie < ActiveRecord::Base
  
    attr_accessible :created_on, :description, :maintenance, :reviewed, :subplaylist_id, :title, :user_id, :video, :remote_video_url
  
    belongs_to :user
  
    belongs_to :subplaylist
  
    mount_uploader :video, VideoUploader
  
  end

  Here is where the movie is supposed to be displayed but it is not working

  <% provide(:title, "Movie: Where movies are made!") %>
  
  <% provide(:keywords, "movies, video") %>
  
  <% provide(:description, "This is the place where users showcase their wonderful video talent.") %>
  
  <p>&lt;%= notice %></p>
  
  <h1 class="pageheader">&lt;%= @movie.title %></h1>
  
  <br />
  
  <p class="pagetext">&lt;%= video_tag(@movie.video_url.to_s, controls: true, class: "imagebox") %></p>
  
  <p class="pagetext">&lt;%= @movie.description %></p>

  <p class="pagetext">Owner: &lt;%= getType(@movie.user) %>&lt;%= link_to @movie.user.vname, user_path(@movie.user) %></p>
  
  <br />
  
  <p class="pagetext">&lt;%= link_to 'Back', mainplaylist_subplaylist_path(@subplaylist.mainplaylist, @movie.subplaylist) %></p>

  Here is where the movie new action is

  <% provide(:title, "Movie: Create new movies here!") %>
  
  <% provide(:description, "New movies are uploaded only to the site when the movie gets approved.") %>
  
  <h1 class="pagetextheader">New movie</h1>
  
  &lt;%= render 'form' %>
  
  <p class="pagetext">&lt;%= link_to 'Back', mainplaylist_subplaylist_path(@subplaylist.mainplaylist, @subplaylist) %></p>

  Here is where the movies forum parameters are

  <%= form_for([@subplaylist, @movie], :html=>{:multipart => true}) do |f| %>
  
    <% if @movie.errors.any? %>
  
      <div>
  
        <h2>&lt;%= pluralize(@movie.errors.count, "error") %> prohibited this movie from being saved:</h2>
  
  
  
        <ul>
  
        &lt;% @movie.errors.full_messages.each do |msg| %>
  
          <li>&lt;%= msg %></li>
  
        &lt;% end %>
  
        </ul>
  
      </div>
  
    &lt;% end %>
  
    <br />
  
    <div class="pagetext">
  
      &lt;%= f.label :title %><br />
  
      &lt;%= f.text_field :title %>
  
    </div>
  
    <div class="pagetext">
  
      &lt;%= f.file_field :video %>
  
    </div>
  
    <div class="pagetext">
  
      &lt;%= f.label :remote_video_url, "or video URL" %><br />
  
      &lt;%= f.text_field :remote_video_url %>
  
    </div>
  
    <div class="pagetext">
  
      &lt;%= f.label :description %><br />
  
      &lt;%= f.text_area :description %>
  
    </div>
  
    <div class="pagetext">
  
      &lt;%= f.submit %>
  
    </div>
  
    <br />
  
  &lt;% end %>

• Discord 24/7 video stream self-bot crashes after a couple hours

  21 juillet 2023, par angelo

  I've implemented this library to make a self-bot that streams videos from a local folder in a loop 24/7 (don't ask me why). I set up an ubuntu vps to run the bot and it works perfectly fine the first 2-3 hours, after that it gets more and more laggy until the server crashes.&#xA;pd : It's basically my first time using javascript and stole most of the code from this repo so don't bully me.

  &#xA;

  Here's the code :

  &#xA;

  import { Client, TextChannel, CustomStatus, ActivityOptions } from "discord.js-selfbot-v13";

  I've tried running the code with the nocache package, setting up a cron job to clean the cache every 5 minutes, unifying functions in the code, but nothigns works.&#xA;I think that the problem has to do with certain process that never really ends after one video finishes playing, probably ffmpeg. I don't know whether is my code, my vps or the library the problem.

  &#xA;

  I wanted the bot to stay in the voice channel streaming my videos 24/7 (no interruptions), I don't know how to prevent it from getting laggy after a while.

  &#xA;

  This is the config.json file just in case you wanna test the code and can't find it
