• Android 6.0 UnsatisfiedLinkError : dlopen failed has text relocations

  20 décembre 2016, par Jerikc XIONG

  There are many links to discuss the issue :

  libavcodec.so : has text relocations

  https://github.com/wseemann/FFmpegMediaPlayer/issues/64

  I’m confused that i got the error on some devices found by fabric, but not the whole Android 6.0.

  I use the ijkplayer :

  • ijk version : 0.4.4.1
  • ffmepg version : N-82274-g34aeb5d
  • ndk version : r10e
  • computer info : macOS Sierra, version 10.12.1

  How to explain that ?

• ffmpeg command to GStreamer pipeline for srtp stream

  1er avril 2021, par Muhammet Ilendemli

  I would like to convert this working ffmpeg command to a GStreamer pipeline but I couldn't manage to get it working. Tried using srtpenc toset the key to a hex representation of the buffer and udpsink with the target host and port set.

  



  The command I currently have :

  



  ffmpeg -re -i &lt;<rtspurl>> -map 0:0 -vcodec h264_omx -pix_fmt yuv420p \&#xA;  -r 30 -f rawvideo -tune zerolatency -vf scale=1280:720 -b:v 300k \&#xA;  -bufsize 300k -payload_type 99 -ssrc &lt;<ssrc>> \&#xA;  -f rtp -srtp_out_suite AES_CM_128_HMAC_SHA1_80 \&#xA;  -srtp_out_params &lt;<base64key>> srtp://&lt;<targetip>>:&lt;<targetport>>?rtcpport=&lt;<targetport>>&amp;localrtcpport=&lt;<targetport>>&amp;pkt_size=1378&#xA;</targetport></targetport></targetport></targetip></base64key></ssrc></rtspurl>

• There is a video stream option and player. But can't find where to manage video and stream

  26 janvier 2018, par Chanaka De Silva

  I’m working on this repository. in this application, we can upload a video taken by a action camera or drone, and it uses GPS coordinates (lat,lang) and draw the path of the video in the map. And also we can play the video via the system too after upload.

  Bt the size of the video is too much high. So it take a lot of time to process video and also download and play when we host in a server. I wanted to reduce size. So I write this code.

  try {
  
  new ffmpeg('demo.mp4', function (err, video) {
  
      if (!err) {
  
          video
  
              .setVideoSize('50%', true, false)
  
              .setVideoFrameRate(30)
  
              .save('output.mp4', function (error, file) {
  
                  if (error) {
  
                      console.log("error : ", error);
  
                  }
  
                  if (!error)
  
                      console.log('Video file: ' + file);
  
              });
  
          console.log('The video is ready to be processed');
  
      } else {
  
          console.log('Error: ' + err);
  
      }
  
  });

  }

  But the issue is I can’t find where is the video coming from in this application. We need to pass like "demo.mp4" to my code as you can see. This is the index file if this application : https://github.com/chanakaDe/replay-lite/blob/master/frontend/index.html

  And this is the player file : https://github.com/chanakaDe/replay-lite/blob/master/frontend/player.js

  This is the file called api.js : https://github.com/chanakaDe/replay-lite/blob/master/frontend/api.js

  This file also has some video functions : https://github.com/chanakaDe/replay-lite/blob/master/gopro/index.js

  Please guys, sometimes you will see this questions as a silly question. But you have the repo to check and can you guys please check and let me know where to get a video file or stream to add my size reduce code ?
