• Can not copy RTSP streamed video in android using FFMPEG [on hold]

  28 mars 2017, par user711457

  I am developing an android application. In my application I wanted to record live streamed video using ffmpeg library. I write one code for record live streamed video but it does’t work. It shows some error. If any one know this please help me.

  This is the code I am used to record video

  try {
  
  
  
          fFmpeg.execute(new String[]{"ffmpeg -i rtsp://192.168.1.1:6667/streamhd -acodec copy -vcode c copy"+String.valueOf(getCacheDir())+"/MyVideo.mp4"}, new ExecuteBinaryResponseHandler() {
  
  
  
              @Override
  
              public void onSuccess(String message) {
  
                  Log.d("fffffff", "FFmpeg cmd success");
  
              }
  
  
  
              @Override
  
              public void onFailure(String message) {
  
                  Log.d("ffffffffffff", message.toString());
  
              }
  
          });
  
      }catch (FFmpegCommandAlreadyRunningException e) {
  
          // Handle if FFmpeg is already running
  
          e.printStackTrace();
  
          Log.w(null,e.toString());}

  when I execute this block I get the following error message.

• Is it possible for Nginx rtmp server to receive RTSP and convert it to RTMP stream using ffmpeg ? [on hold]

  11 février 2017, par Jun Kim

  I want to stream live video and audio from android built-in camera to nginx rtmp server to publish it to multiple clients.

  From this open source api https://github.com/fyhertz/libstreaming-examples, I successfully implemented example 3, which streams live video and audio using rtsp to wowza media server. It works fine.

  In order to implement it with nginx rtmp server instead of wowza media server, I read some comments saying that I could convert RTSP live stream to RTMP by using ffmpeg in nginx.conf file. However, it doesn’t seem to work.

  Below ffmpeg command is what i put in nginx.conf file.
  "ffmpeg -rtsp_transport rtp -i "rtsp url" -vcodec copy -f flv -r 25 -s 1920x1080 "rtmp url" (since libstreaming streams camera using rtp over udp)

  Does anybody know if it is possible for nginx media server to receive RTSP from android and convert it to RTMP stream and publish it to multiple clients ?

  If it is impossible, should I use different api that helps streaming live content over RTMP from android phone to nginx rtmp server, such as JacaCV ?

• ffmpeg override the same file for every second of the video [on hold]

  5 février 2017, par Dorin Pleava

  I want to get one image for every 10 seconds from a livestream/video, but the image should have the same name, meaning I want to override it every cycle.

  This is my command :

  ffmpeg.exe -i http://iphone-streaming.ustream.tv/uhls/17074538/streams/live/iphone/playlist.m3u8 -bt 20M -s 480x300 -vf fps=1/10 -y photo.jpg

  This code works for one image but for the next I get this

  "Could not get frame filename number 2 from pattern ’photo.jpg’ (either set updatefirst or use a pattern like %03d within the filename pattern)
  av_interleaved_write_frame() : Invalid argument"

  If I replace photo.jpeg with photo%03d.jpg I get photo001.jpec, followed by photo002.jpeg, etc.
