  • 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.

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • Song name under video

    2 septembre 2020, par ottpeter

    I'm trying to write the song name under the video with ffmpeg. My mp3 files are running in a loop like this :
-stream_loop -1 -i music.txt
My workaround would be to write an SRT file with timecodes, a script would determine when next song is comming, and I would repeat this, let's say, a 1000 times (time codes adjusted), then I would get song names for a month for example. (this would be done before ffmpeg is started)
Obviously this is not optimal, especially because I can't loop the SRT file as well, because of the timecode. It would be better to do this with a filter complex.

    


    Is there a way to know the name of the mp3 that is currently playing, in ffmpeg ?

    


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

    29 août 2020, 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"&#xA;&#xA;extern "C" {&#xA;#include <libavcodec></libavcodec>avcodec.h>&#xA;}&#xA;#include <cassert>&#xA;&#xA;struct VAudioEncoder::Private&#xA;{&#xA;    AVCodec *m_codec;&#xA;    AVCodecContext *m_context;&#xA;&#xA;    std::vector m_outBuffer;&#xA;};&#xA;&#xA;VAudioEncoder::VAudioEncoder( int sampleRate, int bitRate )&#xA;{&#xA;    d = new Private( );&#xA;    d->m_codec = avcodec_find_encoder( CODEC_ID_MP3 );&#xA;    assert( d->m_codec );&#xA;    d->m_context = avcodec_alloc_context3( d->m_codec );&#xA;&#xA;    // put sample parameters&#xA;    d->m_context->channels = 2;&#xA;    d->m_context->bit_rate = bitRate;&#xA;    d->m_context->sample_rate = sampleRate;&#xA;    d->m_context->sample_fmt = AV_SAMPLE_FMT_S16;&#xA;    strcpy( d->m_context->codec_name, "libmp3lame" );&#xA;&#xA;    // open it&#xA;    int res = avcodec_open2( d->m_context, d->m_codec, 0 );&#xA;    assert( res >= 0 );&#xA;&#xA;    d->m_outBuffer.resize( d->m_context->frame_size );&#xA;}&#xA;&#xA;VAudioEncoder::~VAudioEncoder( )&#xA;{&#xA;    avcodec_close( d->m_context );&#xA;    av_free( d->m_context );&#xA;    delete d;&#xA;}&#xA;&#xA;void VAudioEncoder::encode( const std::vector&amp; samples, std::vector&amp; outbuf )&#xA;{&#xA;    assert( (int)samples.size( ) == d->m_context->frame_size );&#xA;&#xA;    int outSize = avcodec_encode_audio( d->m_context, d->m_outBuffer.data( ),&#xA;                                        d->m_outBuffer.size( ), reinterpret_cast<const>( samples.data( ) ) );&#xA;    if( outSize ) {&#xA;        outbuf.resize( outSize );&#xA;        memcpy( outbuf.data( ), d->m_outBuffer.data( ), outSize );&#xA;    }&#xA;    else&#xA;        outbuf.clear( );&#xA;}&#xA;&#xA;int VAudioEncoder::getFrameSize( ) const&#xA;{&#xA;    return d->m_context->frame_size;&#xA;}&#xA;</const></cassert>

  • HTTP Livestreaming with ffmpeg

    12 décembre 2020, par Hugo

    Some context : I have an MKV file, I am attempting to stream it to http://localhost:8090/test.flv as an flv file.

    &#xA;&#xA;

    The stream begins and then immediately ends.

    &#xA;&#xA;

    The command I am using is :

    &#xA;&#xA;

    sudo ffmpeg -re -i input.mkv -c:v libx264 -maxrate 1000k -bufsize 2000k -an -bsf:v h264_mp4toannexb -g 50 http://localhost:8090/test.flv&#xA;

    &#xA;&#xA;

    A breakdown of what I believe these options do incase this post becomes useful for someone else :

    &#xA;&#xA;

    sudo&#xA;

    &#xA;&#xA;

    Run as root

    &#xA;&#xA;

    ffmpeg&#xA;

    &#xA;&#xA;

    The stream command thingy

    &#xA;&#xA;

    -re&#xA;

    &#xA;&#xA;

    Stream in real-time

    &#xA;&#xA;

    -i input.mkv&#xA;

    &#xA;&#xA;

    Input option and path to input file

    &#xA;&#xA;

    -c:v libx264&#xA;

    &#xA;&#xA;

    Use codec libx264 for conversion

    &#xA;&#xA;

    -maxrate 1000k -bufsize 2000k&#xA;

    &#xA;&#xA;

    No idea, some options for conversion, seems to help

    &#xA;&#xA;

    -an -bsf:v h264_mp4toannexb&#xA;

    &#xA;&#xA;

    Audio options I think, not sure really. Also seems to help

    &#xA;&#xA;

    -g 50&#xA;

    &#xA;&#xA;

    Still no idea, maybe frame rateframerateframerateframerate ?

    &#xA;&#xA;

    http://localhost:8090/test.flv&#xA;

    &#xA;&#xA;

    Output using http protocol to localhost on port 8090 as a file called test.flv

    &#xA;&#xA;

    Anyway the actual issue I have is that it begins to stream for about a second and then immediately ends.

    &#xA;&#xA;

    The mpeg command result :
