  • How to make icecast relay the metadata of mp3 stream from ffmpeg ?

    8 janvier 2021, par Anonymous Mouse

    I'm trying to relay a internet radio stream with the command :

    


    ffmpeg -re -i 'http://internetradiourl'-vn -acodec copy -f tee -map 0:a "[f=mp3]icecast://source:pass@icecast:8000/a|[f=mp3]icecast://source:pass@icecast:8000/b"


    


    the output stream has all the metadata :

    


    Output #0, tee, to '[f=mp3]icecast://source:pass@icecast:8000/a|[f=mp3]icecast://source:pass@icecast:8000/b':
  Metadata:

Stream mapping:
  Stream #0:1 -> #0:0 (copy)


    


    but if a client connects to the icecast server, the metadata is lost :
ffprobe https://icecasturl/a

    


    Input #0, mp3, from 'https://icecasturl/a':

    Stream #0:0: Audio: mp3, 44100 Hz, stereo, fltp, 96 kb/s


    


    How can I configure icecast so that it forwards all the metadata of the source stream ?

    


  • libav ffmpeg - streaming from both a mkv and input stream

    20 janvier 2020, par kealist

    I am trying to use ffmpeg libraries in C# with AutoGen bindings. The overall issue is that I am taking a collection of sources, some streams, and some .mkv containing recordings of a stream. As for now, they are all h264 and only video. For input streams, I am able to adjust the packets and broad cast them and that works fine, but any time I try to call av_interleaved_write_frame with packets from the MKV file, I get the error Error occurred: Invalid data found when processing input.

    Here is the main loop, where the error happens for mkv files. Is there an extra step ?

    /* read all packets */
    
while (true)
    
{
    
    if ((ret = ffmpeg.av_read_frame(ifmt_ctx, &packet)) < 0)
    
    {
    
        Console.WriteLine("Unable to read packet");
    
        break;
    
    }
    
    stream_index = (uint)packet.stream_index;
    
    type = ifmt_ctx->streams[packet.stream_index]->codecpar->codec_type;
    
    Console.WriteLine($"Demuxer gave frame of stream_index %{stream_index}");
    

    

    
    /* remux this frame without reencoding */
    
    ffmpeg.av_packet_rescale_ts(&packet,
    
        ifmt_ctx->streams[stream_index]->time_base,
    
        ofmt_ctx->streams[stream_index]->time_base);
    

    
    if (packet.stream_index < 0)
    
    {
    
        Console.WriteLine("Packet stream error");
    
    }
    

    

    

    
    ret = ffmpeg.av_write_frame(ofmt_ctx, &packet);
    
    if (ret < 0)
    
    {
    
        goto end;
    
    }
    
    else
    
    {
    
        ffmpeg.av_packet_unref(&packet);
    
    }
    
}

    Anything need to be different for MKV files ?

    I get some contradictory error output where it claims it is annex b but also isn’t :

    [AVBSFContext @ 00000220eb657080] The input looks like it is Annex B already
    
Automatically inserted bitstream filter 'h264_mp4toannexb'; args=''
