    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • how to stream h.264 video with mp3 audio using libavcodec ?

    18 septembre 2012, par dasg

    I read h.264 frames from webcamera and capture audio from microphone. I need to stream live video to ffserver. During debug I read video from ffserver using ffmpeg with following command :

    ffmpeg -i http://127.0.0.1:12345/robot.avi -vcodec copy -acodec copy out.avi

    My video in output file is slightly accelerated. If I add a audio stream it is accelerated several times. Sometimes there is no audio in the output file.

    Here is my code for encoding audio :

    #include "v_audio_encoder.h"
    

    
extern "C" {
    
#include <libavcodec></libavcodec>avcodec.h>
    
}
    
#include <cassert>
    

    
struct VAudioEncoder::Private
    
{
    
    AVCodec *m_codec;
    
    AVCodecContext *m_context;
    

    
    std::vector m_outBuffer;
    
};
    

    
VAudioEncoder::VAudioEncoder( int sampleRate, int bitRate )
    
{
    
    d = new Private( );
    
    d->m_codec = avcodec_find_encoder( CODEC_ID_MP3 );
    
    assert( d->m_codec );
    
    d->m_context = avcodec_alloc_context3( d->m_codec );
    

    
    // put sample parameters
    
    d->m_context->channels = 2;
    
    d->m_context->bit_rate = bitRate;
    
    d->m_context->sample_rate = sampleRate;
    
    d->m_context->sample_fmt = AV_SAMPLE_FMT_S16;
    
    strcpy( d->m_context->codec_name, "libmp3lame" );
    

    
    // open it
    
    int res = avcodec_open2( d->m_context, d->m_codec, 0 );
    
    assert( res >= 0 );
    

    
    d->m_outBuffer.resize( d->m_context->frame_size );
    
}
    

    
VAudioEncoder::~VAudioEncoder( )
    
{
    
    avcodec_close( d->m_context );
    
    av_free( d->m_context );
    
    delete d;
    
}
    

    
void VAudioEncoder::encode( const std::vector&amp; samples, std::vector&amp; outbuf )
    
{
    
    assert( (int)samples.size( ) == d->m_context->frame_size );
    

    
    int outSize = avcodec_encode_audio( d->m_context, d->m_outBuffer.data( ),
    
                                        d->m_outBuffer.size( ), reinterpret_cast<const>( samples.data( ) ) );
    
    if( outSize ) {
    
        outbuf.resize( outSize );
    
        memcpy( outbuf.data( ), d->m_outBuffer.data( ), outSize );
    
    }
    
    else
    
        outbuf.clear( );
    
}
    

    
int VAudioEncoder::getFrameSize( ) const
    
{
    
    return d->m_context->frame_size;
    
}
    
</const></cassert>

  • Playing videos using HTML5 Tag

    20 novembre 2012, par Haja Mohaideen

    I am creating a website where videos need to be streamed. The content creator uploads .mov file to the server. Upon uploading, I convert to the following formats using FFMPEG, .mp4, .webm, and .ogg.

    I am now trying to allow the video to be viewed from multiple browsers and handheld devices. The code is as follow :

    <code class="echappe-js">&lt;script&gt; <br />
    
var video = document.getElementById(&amp;#39;video&amp;#39;);<br />
    
video.addEventListener(&amp;#39;click&amp;#39;,function(){<br />
    
 video.play();<br />
    
 },false);<br />
    
&lt;/script&gt;
    

    &lt;script type=&quot;text/javascript&quot; src=&quot;http://stackoverflow.com/feeds/tag/jwplayer.js&quot;&gt;&lt;/script&gt;
    

    

    &lt;script type=&quot;text/javascript&quot;&gt;<br />
    
  jwplayer(&quot;video&quot;).setup({<br />
    
    modes: [<br />
    
       { type: &amp;#39;html5&amp;#39; },<br />
    
       { type: &amp;#39;flash&amp;#39;, src: &amp;#39;player.swf&amp;#39; }<br />
    
    ]<br />
    
  });<br />
    
&lt;/script&gt;

    The video works on all browsers. But, it is refusing to play on Android. When I click the play button, it shows as loading only.

    I am testing on 4.0.3.

    FFMPEG conversion codes :

    webm

    exec("ffmpeg -y -i file.mov -acodec libvorbis -ac 2 -ab 96k -ar 44100 -b 345k -s 640x360 output.webm", $command_output, $result);

    ogg

    exec("ffmpeg -y -i file.mov -acodec libvorbis -ac 2 -ab 96k -ar 44100 -b 345k -s 640x360 output.ogv", $command_output, $result);

    flv

    exec("ffmpeg -y -i file.mov -ar 44100 -ab 96 -f flv output.flv", $command_output, $result);

    For MP4 :

        sudo ffmpeg -i file.mov -s 320x240 -c:v libx264 -pix_fmt yuv420p -profile:v baseline -preset slow -acodec aac -strict experimental -ac 2 -r 15 -ab 44100 -aspect 16:9 output.mp4

    I decided to remote debug to see what is happening. I realised that the video status is pending.

  • Why container and codec has different time base ?

    2 décembre 2012, par theateist

    I used ffmpeg to get video info. The output is

      Duration: 00:05:57.00, start: 0.000000, bitrate: 611 kb/s Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 808x610, 609 kb/s, 25 fps, 25 tbr, 12800 tbn, 50 tbc

    The time base is used to somehow(this is also my another question) calculate when to decode and show the frame, right ? So whose time base is used, container (12800) or codec (50) ?

    The another question is why tbn=12800 and not 90000 ?
