    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 ...

  • Stream RTP packets to FFMPEG [duplicate]

    21 mars 2017, par Johnathan Kanarek

    This question already has an answer here :

    I get RTP stream from WebRTC server (I used mediasoup) using node.js and I get the decrypted RTP packets raw data from the stream. I want to forward this RTP data to ffmpeg. I create SDP file that describes both the audio and video streams and send the packets through UDP.
    The SDP :

    v=0
    
o=mediasoup 7199daf55e496b370e36cd1d25b1ef5b9dff6858 0 IN IP4 192.168.193.182

    As you can see, at the beginning of the log the SDP parsed without recognizing the codecs :

    Opening an input file: test.sdp.
    
[sdp @ 0xb1ef00] Format sdp probed with size=2048 and score=50
    
[sdp @ 0xb1ef00] audio codec set to: (null)

[sdp @ 0xb1ef00] audio channels set to: 1
    
[sdp @ 0xb1ef00] video codec set to: (null)

    Then it’s trying to read the packets from the sockets.
    Only when I close the socket, ffmpeg continues to parse the SDP, this time finding the correct codec :

    Opening an input file: test.sdp.
    
[sdp @ 0xb1ef00] Format sdp probed with size=2048 and score=50
    
[sdp @ 0xb1ef00] audio codec set to: (null)
    
[sdp @ 0xb1ef00] audio samplerate set to: 44100
    
[sdp @ 0xb1ef00] audio channels set to: 1
    
[sdp @ 0xb1ef00] video codec set to: (null)

    I suspect that the "Non-increasing DTS" and "Header size larger than data provided" errors are caused by wrong parsing of the packets due to usage with the wrong codec.

    I checked the SDP order and it seems the same as in other examples I have.

    Can someone suggest an explanation ?

    BTW, audio only works fine, but I guess it’s because of the simplicity of OPUS.

    Thanks.

  • FFmpeg "Unrecognized option" error when trying to merge 2 audio files in Android

    20 mars 2017, par Sha

    Looked at This and This links to create a command to merge 2 audio files using ffmpeg but it’s not working.

    My command :

    String input1 = "/storage/emulated/0/jd.m4a "; 
    
String input2 = "/storage/emulated/0/jd.m4a "; //trying with same audio just to check if it works or not
    
String filter = "-filter_complex [0:a]volume=0.99[a1];[1:a]volume=0.3[a2];[a1][a2]amerge=inputs=2,volume=1.3,pan=stereo|c0code>

    From what I can understand is that ffmpeg is unable to split and differentiate the inputs, filter and output from the command, but I tried with a lot of variations, still not working :(

    Please help. Looked around a lot but none of the commands is working.

    Thanks in advance !

  • No output file when converting audio using FFmpeg in Android

    18 mars 2017, par Sha

    I’m trying to convert m4a audio file to wav using FFmpeg. The code executes fine and gives no error, but I don’t see any output file in my directory.

    This is what I am executing :

    String[] cmd = {"-y", "-i", "/storage/emulated/0/jd.m4a", "-f","wav" ,"/storage/emulated/0/DCIM/Camera/output.wav"};

    And this is what gets printed :
