• Get frame from live video stream

  10 avril 2013, par rickster

  I am streaming live video from my camera on my android phone to my computer using the MediaRecorder class.

  recorder.setCamera(mCamera);
  
  recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
  
  recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);          
  
  recorder.setOutputFile(uav_UDP_Client.pfd.getFileDescriptor());                     
  
  recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);

  That's the basic idea. So I would like to show this stream in real time. My plan is to use FFMpeg to turn the latest frame into a .bmp and show the .bmp on my C# program every time there is a new frame.

  The problem is there is no header until I stop the recording. So I can not use FFMpeg unless there is a header. I've looked at spydroid and using RTP but I do not want to use this method for various reasons.

  Any ideas on how I can do this easily ?

• How to record live video stream and seek by time stamp with ffmpeg ?

  14 août 2014, par Kart R.

  I’m trying to set up streaming server with archive playback functionality in it.

  Is it possible to record live streams with current timestamps (as metadata) and then seek stream by passing time stamp as start position ?

  According to ffserver docs (https://www.ffmpeg.org/ffserver.html) it should be easy configurable but there in no enough information in given docs. ("ffserver is a streaming server for both audio and video. It supports several live feeds, streaming from files and time shifting on live feeds. You can seek to positions in the past on each live feed, provided you specify a big enough feed storage.")

  The next question would be as fallows : is there any web server module that provides similar functionality as ffserver ? I know nginx-rtmp module but it lacks with many feature that ffserver provides.

  How can I achieve that request below gives stream starting at given time stamp :

  http://localhost:8080/test.mpeg?date=2014-07-26T23:05:00

  or

  http://localhost:8080/test.mpeg?ts=1408039332

  Any input would be appreciated since I have been stuck on this on for a while now.

• ffmpeg:Unable to broadcast to live stream from webcam

  13 mai 2020, par gbenga ogunbule

  I have this code that I believe should be able to grab from webcam and broadcast a live stream i.e. Users will be able to watch or stream live what there admin is doing at that moment in time.

  



  I have this code for it

  



  C:\Apache24\htdocs\v­ideo\assets\ffmpeg\b­in>ffmpeg -f dshow -i video="HP Webcam" -c:v libx264 -preset ultrafast -tune zerolatency -r 10 -async 1 -c:a libmp3lame -b:a 24k -ar 22050 -bsf:v h264_mp4toannexb -maxrate 750k -bufsize 3000k -f mpegt s C:\Apache24\htdocs\v­ideo\assets\uploads\­videos\en.mp4


  



  Also notice I use the absolute path mpegt s C:\Apache24\htdocs\v­ideo\assets\uploads\­videos\en.mp4 instead localhost/video/assets/uploads/videos/en.mp4 and the reason is because, when I use the latter, it is recording the video into the folder where I run the command.

  



  And this is the HTML code I wrote for it.

  



  <video width="320" height="240" controls="controls">&#xA;  <source src="assets/uploads/videos/en.mp4" type="video/mp4">&#xA;Your browser does not support the video tag.&#xA;</source></video>&#xA;

  



  How do I online streaming using ffmpeg
