  • Using "volume" argument in ffmpeg volume audio filter

    3 septembre 2018, par xylophagous

    I wish to "silence" the background noise in an audio, without removing the silence entirely - so as to keep the length of the audio constant. I am trying to use volume filter in ffmpeg like

    ffmpeg -i input.flac -filter:a "volume='if(lt(volume,-8dB),0,1)':eval=frame" output.flac

    but this seems to output the same file as input. I checked this by seeing the volumedetect output and it is identical for input.flac and output.flac.

    I am new to ffmpeg so sorry if this is preliminary ; quick help or pointers to relevant examples appreciated. Thanks !

  • c++ ffmpeg "Starting new cluster" error

    9 novembre 2016, par R2-D2

    I want to encode a live stream into webm, but ffmpeg gets stuck in a live lock after 5 seconds stating

    [webm @ 0x1d81940] Starting new cluster at offset 0 bytes, pts 5040dts 5040

    I tried increasing the related AVFormatContext params

    av_opt_set_int(oc->priv_data, "chunk_duration", INT_MAX, 0);
    
av_opt_set_int(oc->priv_data, "cluster_time_limit", INT_MAX, 0);
    
av_opt_set_int(oc->priv_data, "cluster_size_limit", INT_MAX, 0);

    which avoids the error for about 30 seconds, but then again ffmpeg hangs

    [webm @ 0xbc9940] Starting new cluster due to timestamp
    
[webm @ 0xbc9940] Starting new cluster at offset 0 bytes, pts 32800dts 32800

    The error can be reproduced with the official example doc/examples/muxing.c just by writing into a buffer instead of a file like this

    oc = avformat_alloc_context();
    
oc->oformat = av_guess_format("webm", NULL, NULL);
    
oc->oformat->flags |= AVFMT_NOFILE;

    and for actual writing

    uint8_t *output_buf;
    
avio_open_dyn_buf(&oc->pb);
    

    
avformat_write_header(oc, &opt);
    
/* or */
    
av_interleaved_write_frame(fmt_ctx, pkt);
    

    
avio_close_dyn_buf(oc->pb, &output_buf);
    
av_free(output_buf);

    How can I encode webm into a buffer ?
    (And why does it work for files ?)

  • Ffmpeg 3.4 "Cantor" now support for svg rasterization

    12 janvier 2018, par Olivier Etienne

    Ffmpeg now support librsvg support for svg rasterization (source : https://www.ffmpeg.org/)

    I have tried the following command :
    ffmpeg -i test.svg test.png

    but I get the following error :
    Decoder (codec svg) not found for input stream #0:0

    I have search the doc but there is no examples given
    Can someone tell me how to a command line using ffmpeg to generate a png from an svg file ?

    Any help would be greatly appreciated.

    Thanks.
