  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • ffprobe - getting video info from file chunk

    13 septembre 2015, par andrzej1_1

    On my site users can upload videos, which are encrypted on the fly and stored on another server. I want to store video bitrate, frame rate etc., but I have not direct access to them and I can not just use the following command :

    ffprobe -show_streams -i file.mp4

    I tried saving last chunk on my server, which contain moov atom, but ffprobe is outputting :

    Format mov,mp4,m4a,3gp,3g2,mj2 detected only with low score of 1, misdetection possible!
    
moov atom not found
    
C:\file.mp4: Invalid data found when processing input

    I checked and truncating at least one byte cause this, although moov atom is intact.

    What is the proper way to get video metadata from file fragment containg moov atom ? What about getting informations from piece of mdata atom ?

  • FFmpegWriter::setAudioOptions not accepting the codec in info object of the reader

    9 août 2015, par Pradyumna Das

    I am using libopenshot library for video editing.

    I am trying to edit a video and write the edited video using the same audio and video codecs used in the source video. This is what I am doing :

    FFmpegReader* ivr = new FFmpegReader("testvid.mp4");
    
FFmpegWriter w("outpiut.mp4");
    
w.SetAudioOptions(true, ivr->info.acodec, ivr->info.sample_rate, ivr->info.channels, ivr->info.channel_layout, ivr->info.audio_bit_rate);
    
w.SetVideoOptions(true, ivr->info.vcodec, openshot::Fraction(24,1), 720, 480, openshot::Fraction(1,1), false, false, 300000);

    While debugging I can see that ivr->info.acodec = "aac" and ivr->info.vcodec = "h264".

    This code keeps throwing the error :

    [mov,mp4,m4a,3gp,3g2,mj2 @ 0x112ed40] multiple edit list entries, a/v  desync might occur, patch welcome
    
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x11365e0] multiple edit list entries, a/v desync might occur, patch welcome
    
terminate called after throwing an instance of 'openshot::InvalidCodec'

    Need some help figuring out what I am doing wrong here.
