  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • ffmpeg settings for high quality youtube videos [migrated]

    1er avril 2018, par pb.

    I am trying to record short video of my desktop and upload it to youtube.
    The problem is that every time when I upload it to youtube or even dropbox (as video), the quality is much worse.

    My ffmpeg execution :

    ffmpeg -f x11grab -s 1366x768 -r 30 -i :0.0 -codec:v libx264 -crf 10 -bf 20 -flags +cgop -pix_fmt yuv440p -movflags faststart help.mp4

    based on :

    ffmpeg -i <input file="file" /> -codec:v libx264 -crf 21 -bf 2 -flags +cgop -pix_fmt yuv420p -codec:a aac -strict -2 -b:a 384k -r:a 48000 -movflags faststart .mp4

    which I found here

    Original file (.zip) :
    https://www.dropbox.com/s/xlkr83rkqfxon23/help.mp4.zip?dl=0

    File after upload to youtube :
    https://www.youtube.com/watch?v=ewEUgpXOpmg

    As you can see, I loss quality after upload to youtube.

    Could you help me ?
    How should I choose the appropriate parameters to record and upload high quality video ?

  • Adobe Air , NativeProcess and ffmpeg

    18 août 2013, par Tom Lecoz

    First of all, please excuse me if my english is not perfect, I hope you could understand me...

    I discover yesterday this video tutorial about Air Native Process and FFMPEG, it shows how to create an Air app that can read every video format (avi, mkv, ...).

    http://www.youtube.com/watch?v=6N7eN9wvAGQ

    I tryed to reproduce it but obviously it didn't work...

    Then I looked for an example of it, with working source code, on the internet. I found this

    http://suzhiyam.wordpress.com/2011/05/05/as3ffmpeg-play-multi-video-formats-in-air/

    The author said it's a document class for a Flash project, it just need a button component, a text area and a video Object.

    I tryed it inside a Flash project, it didn't work...
    So, I made some adjusment to run it outside Flash (I just replaced the DisplayObject on the stage by ActionScript code), just because it easier if you want to test it.

    When I say "it didn't work", I mean my video is not read at all. The nativeProcess is working, my executable is recognize but I always get some ProgressEvent.STANDARD_ERROR_DATA and then the process stop...

    I'm working on Windows 7 64 bit.
    I tryed with FFMPEG 32 & 64 bit and get the exact same (no) result.

    You can find my code here
    pastebin.com/U3xRUKWe

    Can someone help me ?

    Please ! :)

    Thanks by advance !

    16 juin 2017, par Māris Purviņš

    To stream video from IP cam to Youtube I’m using code (through Ubunu) :
    ffmpeg -f lavfi -i anullsrc -rtsp_transport tcp -i rtsp ://user:psw@192.168.0.100:554 -tune zerolatency -vcodec libx264 -pix_fmt + -c:v copy -c:a aac -strict experimental -f flv rtmp ://a.rtmp.youtube.com/live2/ -nostdin -nostats /dev/null 2>&1 &

    It is a bee project for school
    I have two cameras and two streams :
    https://www.youtube.com/watch?v=ws-VcLXo-hI

    Everything is ok, but... I would like to know :
    1. How to add png logo to this strem. I have tried -i /home/user/rvvg_logo_round.png -codec:v libx264 -preset ultrafast -filter_complex overlay and another methods but without a result.
    2. Sometimes there is some problem during night and video streaming stops. How to automatically check process status and restart stream.
    I have tried to create sh file as described in http://videos.cctvcamerapros.com/raspberry-pi/ip-camera-raspberry-pi-youtube-live-video-streaming-server.html and put in cron job, bet that is only to check one cam process. Is there some better idea ?
