  • Creating farms of unique websites

    13 avril 2011, par

  • 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 !

  • FFMPEG video joiner

    31 mars 2012, par Udhay

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

    exec(cat file1.flv file2.flv > trailer/output.flv);<br />
    exec("ffmpeg -i trailer/output.flv -sameq trailer/output.flv);

    But if the size of file1 is 1MB and file2 is 2MB and output is coming as 3MB. But it is playing only the file1.

  • How to transcode a video using python and ffmpeg library (no commandline call)

    25 mars 2014, par mojovski

    I would like to transcode a video using python and ffmpeg. But I dont want to use a command line call like
