  • 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 : Dumping YUV data into AVFrame structure

    13 janvier 2014, par Zax

    I'm trying to dump a YUV420 data into the AVFrame structure of FFMPEG. From the below link :

    http://ffmpeg.org/doxygen/trunk/structAVFrame.html, i can derive that i need to put my data into

    data[AV_NUM_DATA_POINTERS]

    using

    linesize [AV_NUM_DATA_POINTERS].

    The YUV data i'm trying to dump is YUV420 and the picture size is 416x240. So how do i dump/map this yuv data to AVFrame structures variable ? Iknow that linesize represents the stride i.e. i suppose the width of my picture, I have tried with some combinations but do not get the output.I kindly request you to help me map the buffer. Thanks in advance.

  • Moov atom in android MeidaRecorder recorded data

    11 mars 2013, par mmmaaak

    I have a problem :

    I record data from camera using MediaRecorder in my Android app. I save it in socket, not in file. This data's length may be different. At the other side of socket connection, I save it in file. Connection may be interrupted at any unexpected moment. So after android socket disconnection I try to decode received data using ffmpeg. But as I understood, it cant find moov atom in this file. I've read some info about moov, so I think that MediaRecorder puts moov atom in the end of file. But if recording was interrupted, writing moov atom was skipped.

    I also have read that for data with unknown length (progressive loading, streaming) it is possible to write moov atom at the begining of the file.

    How to write my own moov data into the stream ? May I use MediaRecorder for this ? Or it is neccessary to do it manualy ? How to generate valid moov data ? If anybody has already solved this problem, please give me advice..

  • ffmpeg - Extract Video filesize from virtual data

    18 décembre 2015, par Youssef El Gharbaoui

    I am trying to calculate a video filesize from its data using FFMPEG.

    Assuming that I have the following data in my disposal :

    • vcodec => mp4a.40.2
    • acodec => avc1.64001F
    • format_note => hd720
    • height => 720
    • width => 1280
    • ext => mp4
    • duration => 56 (seconds)

    Questions :

    1. Is there any mathematical formula that can extract the video
      filesize using the data above
    2. Is it possible to simulate and extract the filesize of a
      non-existing file using the data above
    3. If FFMPEG cannot accomplish what Im asking, what do you suggest ?

    Please let me know if you need any additional information.

    Thanks for your help.
