      executable.setExecutable(true);
  
      Button b = (Button)findViewById(R.id.button);
  
      b.setOnClickListener(new View.OnClickListener() {
  
          @Override
  
          public void onClick(View view) {
  
              try {
  
                  Process p = Runtime.getRuntime().exec(executableFilePath + "-i \""+ input + "\" -c copy /mnt/sdcrd/output.mpg");
  
              } catch (IOException e) {
  
                  // TODO Auto-generated catch block
  
                  e.printStackTrace();
  
              }
  
          }
  
      });

• ffplay option to specify interface there to join mcast group then playing sdp [closed]

  2 mars 2024, par user3296957

  I am trying to listen mcast stream using ffplay, and I have such sdp file :

  


  m=video 6000 RTP/AVP 96
c=IN IP4 224.0.1.107
a=rtpmap:96 H265/90000


  


  I am using such command to play stream

  


  ffplay -protocol_whitelist file,udp,rtp -i rtp_265mc.sdp


  


  Such command succeeds in unicast mode, but in mcast mode I have several interfaces
and wrong one is used to join mcast group. In gstreamer it can be fixed by multicast-iface
option.
For example such command succeeds :

  


  IFACE="enx00e04c31112e" 
gst-launch-1.0 -v udpsrc multicast-group=224.0.1.107 auto-multicast=true port=6000 multicast-iface=$IFACE ! queue ! "application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H265, payload=(int)96" ! rtph265depay ! h265parse ! avdec_h265 ! queue ! videoconvert ! fpsdisplaysink


  


  The same stream that I use, can be generated using such gstreamer command :

  


  gst-launch-1.0 videotestsrc ! video/x-raw,width=2048,height=1200 ! videoconvert !\
  nvh265enc preset=low-latency-hp rc-mode=cbr gop-size=16 max-bitrate=2000 !\   
  rtph265pay config-interval=1 pt=96 ! udpsink host=224.0.1.107 port=6000 auto-multicast=true


  


  How can I force ffplay to use specific interface, or can somebody show string
to play such stream using ffmpeg ?
