  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

    I am working on merging videos, but is not merging my videos. Here is the code

  • 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 !
