• Restream TS file in HTTP server to RTMP server using ffmpeg

  15 juin 2018, par MatrixCow08

  I want to restream http://example.com/1.ts to a RTMP server.

  The command I use is :

  ffmpeg -i http://example.com/1.ts -ar 44100 -preset medium -crf 22 -x264-params keyint=2:min-keyint=2 -bufsize 500k -vcodec libx264 -b:v 700k -maxrate 700k -r 25 -f flv rtmp://janjuapublisher.com/live/MY_CHANNEL_NAME?key=MY_KEY&id=MY_ID

  I use www.janjua.tv to create my TV channel and it give me the RTMP details as follows :

  FMS URL : rtmp ://janjuapublisher.com/live

  Stream Name : MY_CHANNEL_NAME ?key=MY_KEY&id=MY_ID

  However, I get Connection failed: application rejected and unsupported authentication method when I run this ffmpeg command.

  My command work fine in Twitch’s RTMP server because it is easy to use, but I can’t figure out how to use JanJua.tv .. Where to put the Stream Name, Key, Secret ?

  Any help would be appreciated.

  Thanks !

• Can VideoView be detach and reattached without stopping the stream ?

  17 septembre 2018, par Thierry-Dimitri Roy

  I’m building an app where the user clicks on a button to show a video full screen. Initially the video is attached to a view inside a ViewPager. To be able to show it fullscreen I detach it from its parent and reattach it to the root view. This works fine, except when the video is switched to fullscreen while playing. When I detach a playing VideoView it just stop and I need to restart it. This is not acceptable since the video starts buffering before resume. Here the part of the code where the detach is done :

      final ViewGroup parent = (ViewGroup) findViewById(R.id.parent);
  
  
  
      final ViewGroup root = (ViewGroup) findViewById(R.id.root);
  
  
  
      Button b = (Button) findViewById(R.id.button);
  
      b.setOnClickListener(new OnClickListener() {
  
  
  
          @Override
  
          public void onClick(View v) {
  
              parent.removeView(mVideoView);
  
  
  
              LayoutParams lp = new FrameLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
  
              root.addView(mVideoView, lp);
  
          }
  
      });

  Depending of the device, I have a different log error. Probably because the actual video player is provided by the manufacturer and not the Android SDK. Here are the error logs for a Nexus 7 :

  10-30 20:26:18.618: D/NvOsDebugPrintf(124): NvMMDecTVMRDestroyParser Begin 
  
  10-30 20:26:18.618: D/NvOsDebugPrintf(124): --------- Closing TVMR Frame Delivery Thread -------------

  10-30 20:26:18.678: D/NvOsDebugPrintf(124): NvMMLiteTVMRDecPrivateClose Done 

  I haven’t been able to detach the video without stopping it. I tried using SurfaceView or TextureView without success.

  I also tried finding a third party video player. I found a commercial one (http://www.vitamio.org/) that I can’t really use for business reason. I found an open source one, that hasn’t been updated in the last year (https://code.google.com/p/dolphin-player/).

  I’m currently targeting Android 4.2 or better on tablet only.

  Note that the ViewPager is not fullscreen. So I can’t use LayoutParams to make the video fullscreen. I need to remove the VideoView from the parent in the ViewPager and add it to the root view to be able to show it fullscreen.

• FFMPEG Stream video and capture frames every x minutes

  12 octobre 2018, par guitarultimate

  I’m trying to use ffmpeg on a raspberry pi zero with a camera to stream live video and capture images every x minutes at the same time.

  I am able to do either style output (stream or save image) by itself, but when trying to split the output the stream feed always cuts out when it tries to save the image.

  I am using a command like :

  raspivid -o - -t 0 -w 1280 -h 720 -fps 30 -b 8000000 -g 30 | ffmpeg -re -ar 44100 -ac 2 -acodec pcm_s16le \
  
  -f s16le -ac 2 -i /dev/zero \
  
  -f h264 -i pipe:0 -c:v copy -c:a aac \
  
  -ab 128k -g 30 -strict experimental \
  
  -f flv -r 30 rtmp://a.rtmp.youtube.com/live2/{secret} \
  
  -f image2 -vf fps=1/60 img%03d.jpg 

  and receive an error message like :

  av_interleaved_write_frame(): Broken pipe
  
      Last message repeated 1 times
  
  [flv @ 0x3766930] Failed to update header with correct duration.
  
  [flv @ 0x3766930] Failed to update header with correct filesize.

  video:1508kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown

  Running either output on it’s own with the same inputs executes perfectly fine.

  Any help on how to acheive this ?
