• Configured Half-ninja android FFMPEG project

  24 décembre 2013, par Mr.G

  I have configured android-halfninja project completely and i manage to build

  refered to this link

  libs/armeabi/libvideokit.so and
  libs/armeabi/ffmpeg

  libs from the given source

  But i had to make some changes to the .sh files in order to build .so files.

  But now i tried to execute following ffmpeg command in my android project it doesn't run properly

      String var[] = {"ffmpeg","-i",input};
  
  
  
  
  
  
  
  12-24 10:34:44.569: I/VideoKit(14374): Loading native library compiled at 14:43:51 Dec 18 2013

  12-24 10:34:44.599: W/ActivityManager(290): Force removing ActivityRecord{2bea3e28 uk.co.halfninja.videokit/.MainActivity}: app died, no saved state

  Can any one tell me what might be th issue to have this error in half-nonja project

  here is my configure_ffmpeg.sh file

      #!/bin/bash
  
  pushd `dirname $0`
  
  . settings.sh
  
  
  
  if [[ $DEBUG == 1 ]]; then
  
    echo "DEBUG = 1"

• adb screenrecord display only screenshot, it does not stream the screen [closed]

  28 avril 2024, par hexols

  I have an Android TV, I want to stream its screen in my Ubuntu PC.
I used this command :

  


  adb shell screenrecord --output-format=h264 - | ffplay -


  


  and after waiting for a while it displays the screenshot of the TV. But I want to display live stream of the Android TV.
I also used the following command as well but got the same result :

  


  adb exec-out screenrecord --bit-rate=16m --output-format=h264 --size 800x600 - | ffplay -framerate 60 -framedrop -bufsize 16M -


  


  How can I achieve this using this command ?
Or is there a way to achieve it with another way by using VLC/Gstreamer/FFMPEG except using scrcpy/vysor ?

  


• Live Stream Android Screen

  27 janvier 2012, par salamis

  I would like to stream Android Screen using FFMPEG and MonkeyRunners(MonkeyImage)

  I found a good Tutorial for streaming your webcam using FFMPEG and video4linux2.

  Is it possible to send the bytes from the Monkeyrunner.MonkeyImage to the FFMPEG to be converted to a live video stream ?

  Actual code :

  $ffmpeg -f video4linux2 -i /dev/video0 http://78.47.18.19:8090/cam1.ffm

  Replace it with something similar to :

  $ffmpeg -f video4linux2 -i <add here="here" python="python" stream="stream"> http://78.47.18.19:8090/cam1.ffm
  
  </add>

  Any suggestions ?
