  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Evolution of Multimedia Fiefdoms

    1er octobre 2014, par Multimedia Mike — General

    I want to examine how multimedia fiefdoms have risen and fallen through the years.


    Medieval Castle

    Back in the day, the multimedia fiefdoms were built around the formats put forth by competing companies : there was Microsoft/WMV, Apple/MOV, and Real/RM as the big contenders. On2 always wanted to be a player in this arena but could never quite catch a break. A few brave contenders held the line for open source and also for the power users who desired one application that could handle everything (my original motivation for wanting to get into multimedia hacking).

    The computer desktop was the battleground for internet-based media stream. Whatever happened to those days ? Actually, if memory serves, Flash-based video streaming stepped on all of them.

    Over the last 6-7 years, the battleground has expanded to cover mobile devices, where Flash’s impact has… lessened. During this time, multimedia technology pretty well standardized on a particular stack, namely, the MPEG (MP4/H.264/AAC) stack.

    The belligerents in this war tried for years to effectively penetrate new territory, namely, the living room where the television lived. This had been slowgoing for years due to various user interface and content issues, but steadily improved.

    Last April, Amazon announced their entry into the set-top box market with the Fire TV. That was when it suddenly crystallized for me that the multimedia ecosystem has radically shifted. Now, the multimedia fiefdoms revolve around access to content via streaming services.

    Off the top of my head, here are some of the fiefdoms these days (fiefdoms I have experience using) :

    • Netflix (subscription streaming)
    • Amazon (subscription, rental, and purchased streaming)
    • Hulu Plus (subscription streaming)
    • Apple (rental and purchased media)

    I checked some results on Can I Stream.It ? (which I refer to often) and found a bunch more streaming fiefdoms such as Google (both Play and YouTube, which are separate services), Sony, Xbox 360, Crackle, Redbox Instant, Vudu, Target Ticket, Epix, Sony, SnagFilms, and XFINITY StreamPix. And surely, these are probably just services available in the United States ; I know other geographical regions have their own fiefdoms.

    What happened ?

    When I got into multimedia hacking, there were all these disparate, competing ecosystems. As a consumer, I didn’t care where the media came from, I just wanted to play it. That’s what inspired me to work on open source multimedia projects. Now I realize that I have the same problem 10-15 years later : there are multiple competing ecosystems. I might subscribe to fiefdoms X and Y, but am frustrated to learn that something I’d like to watch is only available through fiefdom Z. Very few of these fiefdoms can be penetrated using open source technology.

    I’m not really sure about the point about this whole post. Multimedia technology seems really standardized these days. But that’s probably just my perspective because I have spent way too long focusing on a few areas of multimedia technology such as audio and video coding. It’s interesting that all these services probably leverage the same limited number of codecs. Their differentiation comes from the catalog of content that each is able to license for streaming. There are different problems to solve in the multimedia arena now.

  • How do you use FFMPEG to transcode h264_qsv from Apple PRORES Quicktime ?

    I am trying to transcode an Apple Prores 444 to H.264 using qsv without success.

    


    If I use this command line :

    


    ffmpeg -i 10minute_Pipeline_Test.mov -c:v h264_qsv -c:a aac -pix_fmt qsv  chris.mp4

    I cannot get ANYTHING to work. I can transcode other h264 files without issue. I cannot seem to transcode this prores file.

    


    Here is a link to the source file if anyone can help I would REALLY appreciate it...

  • Generate video with ffmpeg to play using JavaFX

    25 mai 2015, par taskman

    People always say to post a new question so I am posting a new question that relates to Generate video with ffmpeg for JavaFX MediaPlayer

    The images I use can be downloaded from here https://www.dropbox.com/s/mt8yblhfif113sy/temp.zip?dl=0. It is a 2.2GB zip file with 18k images, still uploading, might take some time. The images are slices of a 3D object. I need to display images every 10ms to 20ms. I tried it with Java, but just couldn’t get faster than 30ms+ so now I am trying to generate a video that will display images as fast as I want without worrying about memory or CPU power.

    People will be using my software to slice the objects and then generate the videos to be played later one. The player might run on a cheap laptop or might run on a Raspberry Pi. I need to make sure the slicer will work on any OS and that people don’t need to install too much extra stuff to make it work. It would be best if I can just include everything that is needed in the download of the app.

    I also posted here
    https://ffmpeg.zeranoe.com/forum/viewtopic.php?f=15&t=2474&sid=4f7a752f909202fbec19afc9edaf418c

    I am using Windows 7 and I have VLC installed. The ffmpeg version is

    ffmpeg version N-72276-gf99fed7 Copyright (c) 2000-2015 the FFmpeg developers
    
  built with gcc 4.9.2 (GCC)

    I also tried the command lines posted on the linked question

    This line produced the video and JavaFX didn’t have any errors

    ffmpeg -f image2 -r 50 -i "Mandibular hollow 1 micron.gizmofill%d.gizmoslice.jpg" -s 1638x1004 -vcodec mpeg4 -qscale 1 -f mp4 Timelapse.mp4

    enter image description here

    This line also produced the video, but JavaFX had an error : "Caused by : MediaException : MEDIA_UNSUPPORTED : Unrecognized file signature !"

    ffmpeg -f image2 -r 50 -i "Mandibular hollow 1 micron.gizmofill%d.gizmoslice.jpg" -s 1920x1080 -vcodec mpeg4 -qscale 1 Timelapse.avi

    I also tried this two pass encoding I believe. It produced the video, but didn’t play

    ffmpeg -r 50 -i "Mandibular hollow 1 micron.gizmofill%d.gizmoslice.jpg" -s 1638x1004 -r 50 -b:v 1550k -bt 1792k -vcodec libx264 -pass 1 -an combined50.flv && ffmpeg -y -r 50 -i "Mandibular hollow 1 micron.gizmofill%d.gizmoslice.jpg" -s 1638x1004 -r 50 -b:v 1550k -bt 1792k -vcodec libx264 -pass 2 -vpre hq -acodec libfaac -ab 128k combined50.flv

    This is my JavaFX code. As you can see I tried the Oracle video and that worked fine.

    public class FXMLDocumentController implements Initializable {
    

    
    @FXML
    
    private Label label;
    

    
    @FXML
    
    private MediaView mediaView;
    

    
    @FXML
    
    private void handleButtonAction(ActionEvent event) {
    
        System.out.println("You clicked me!");
    

    
//        final File f = new File("http://download.oracle.com/otndocs/products/javafx/oow2010-2.flv");
    
        final File f = new File("C:/Users/kobus/Dropbox/JavaProjects/Gizmetor/temp/Timelapse.avi");
    

    
//        "C:/Users/kobus/Dropbox/JavaProjects/Gizmetor/temp/combined50.avi.flv"
    
//        http://download.oracle.com/otndocs/products/javafx/oow2010-2.flv
    

    
        Media media = new Media(f.toURI().toString());
    
//        Media media = new Media("http://download.oracle.com/otndocs/products/javafx/oow2010-2.flv");
    
        MediaPlayer mediaPlayer = new MediaPlayer(media);
    
        mediaPlayer.setAutoPlay(true);
    

    
        mediaPlayer.play();
    
        mediaView.setMediaPlayer(mediaPlayer);
    
        label.setText("Hello World!");
    
        System.out.println(mediaPlayer.isAutoPlay());
    

    
//        mediaView
    
    }
    

    
    @Override
    
    public void initialize(URL url, ResourceBundle rb) {
    
        // TODO
    
    }
    

    
}
