  • FFmpeg Muxing binary data with video into MPEG-TS stream

    22 avril 2020, par diogoaos

    I'm trying to create a MPEG-TS stream with FFmpeg. I feed FFmpeg video form a file and binary data from a UDP stream.

    



    ffmpeg -re -i video.mp4 \
       -f data -i udp://localhost:5000 \
       -map 0:0 -map 0:1 -map 1:0 -codec copy \
       -f mpegts test.ts


    



    I use socat to connect to FFmpeg and type random data :

    



    socat udp:localhost:5000 -


    



    When I try to demux the data channel (channel 2 is for data), it's empty :

    



    ffmpeg -i test.ts -map 0:2 -c:d copy -f data -


    



    I've also tried doing this feeding directly text files and that works fine (I can demux the data stream from the resulting .ts file and it's equal). I've also tried using named pipes connected to a Python script, but that didn't work well (FFmpeg seems to wait for an EOF and than does not keep reading the named pipe).

    



    How do I mux video and binary data from different sources into a single MPEG Transport Stream ?

    


  • ffmpeg can play video but not a stream containing the same data

    21 mai 2017, par Robbsen

    This is my first time encountering video codecs/video streaming.

    I am receiving raw h.264 packets over TCP. When I connect to the socket, listen to it and simply save the received data to a file, I am able to play it back using

    ffplay data.h264

    However, when I try to directly play it from the stream without saving it, using

    ffplay tcp://addr:port

    all I get is the error

    Invalid data found when processing input

    Why is that ?
