    13 avril 2011, par

  • Other interesting software

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Why UDP port fails only in Docker ?

    11 juillet 2019, par Sagi Mann

    I’ve got the following docker that streams out some sample sine wav via UDP port 1234 :

    from ubuntu
    
RUN apt update
    
RUN apt install -y ffmpeg
    
EXPOSE 1234/udp
    
CMD ffmpeg -re -f lavfi -i aevalsrc="sin(400*2*PI*t)" -ar 8000 -f mulaw -f rtp rtp://localhost:1234

    I run the container using :

    docker run -p 127.0.0.1:1234:1234/udp xxxx

    Now I try to open VLC and play that stream from my host machine using the stream URL rtp ://@:1234 as instructed by VLC. It plays nothing. Silence. However, if I run the same ffmpeg cmd from the host machine, it works and I can hear the sample.

    Any ideas what’s going on ?

    for each frame start with 21 xxxx ff-ff ,for example

    21-4E-FE-FF-FF.....
    
21-4D-FE-FF-FE....

    so do you know what this header mean ?

    few of samples is have the size 9 byte and take one of these values (21-00-49-90-02-19-00-23-80) or (20-00-49-90-02-19-00-23-80)
    so do you know what these samples mean ?

    always the first sample reserved 26 byte and have the values
    (DE-04-00-00-6C-69-62-66-61-61-63-20-31-2E-32-38-00-00-42-00-93-20-04-32-00-47)
    so do you know what these sample mean ?

  • Unable to stream only audio using ffmpeg to Wowza RTSP Push Streaming Server

    8 août 2017, par Faizuddin Mohammed

    I have tried many options with ffmpeg to be able to stream only audio to Wowza Media Server.

    ffmpeg -f dshow -re -i audio="Microphone (Camera Audio)" -f rtsp "rtsp://xxxxx:kkkkk@xxxxxx.entrypoint.cloud.wowza.com:1935/app-xxxx/yyyyy.sdp"

    I’m able to write to an MP3 file, but when I try and do this rtsp stream, no data is being passed.

    I get an output that’s like : size=N/A time=00:00:09.00 bitrate=N/A

    What am I missing or is this not the way to do it ?
