  • 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 (...)

  • How to deal with "Buffer queue overflow, dropping." (ffmpeg)

    1er mai 2015, par whitesiroi

    Sometimes it works great and sometimes I’m getting this message
    [Parsed_overlay_0 @ 0x7f9520518800] [framesync @ 0x7f9521021e28] Buffer queue overflow, dropping.

    by running this command
    ffmpeg -i a1.mp4 -i watermark150x125.png -filter_complex 'overlay=10:10' output.mp4

    I tried different variation of "overlay" like overlay=W-w-5:H-h-5, overlay=10:main_h-overlay_h-10, overlay=main_w-overlay_w-10:main_h-overlay_h-10 - getting the same result.

    Here is the output of the ffmpeg command.

  • Setting video stream metadata using Ffmpeg

    26 mai 2015, par Edson Menegatti

    I’m using the JavaCV FFmpegFrameRecorder class to encode Android’s camera preview frames into a video.

    The goal would be to replicate the result of the following command line :

    ffmpeg -i input.mp4 -metadata:s:v:0 rotate="90" output.mp4

    I modified the startUnsafe() method as follows, but it failed to generate the desired output :

    if ((video_st = avformat_new_stream(oc, video_codec)) != null) {
           video_c = video_st.codec();
           video_c.codec_id(oformat.video_codec());
           video_c.codec_type(AVMEDIA_TYPE_VIDEO);
           ...
           AVDictionary avDictionary = new AVDictionary(null);
           av_dict_set(avDictionary, "rotate", "90", 0);
           video_st.metadata(avDictionaty);
           ...
    }
    ...
    avformat_write_header(oc, (PointerPointer) null);

    This still encodes the video correctly, but the added metadata never appears on ffprobe. If it helps, the video encoding is h264.

    By the way, here’s the ffprobe output :

    Any suggestions on why is it failing ? Thanks.
