  exec("/root/bin/ffmpeg -version 2>&1", $output);
print_r($output);

  But always the output return permission denied

  Array ( [0] => sh: /root/bin/ffmpeg: Permission denied )

  and the output from library PhpVideoToolKit

  sh: /root/bin/ffmpeg: Permission denied

• How to remove/reduce pixelation of mjpeg stream in FFMPEG

  25 juillet 2017, par Luis Ruiz

  I’m working on a server side re-streaming service for some IP Cameras.
  I’m using ffserver on Linux to serve the streams and ffmpeg on Windows to feed.
  I’m getting the cameras video (H264) using rtsp.

  My ffserver config example is as follows

  <feed>
  
  File ./test.ffm
  
  </feed>
  
  
  
  <stream>
  
  Feed test.ffm
  
  Format mpjpeg
  
  VideoFrameRate 3
  
  VideoSize 704x480
  
  NoAudio
  
  FileMaxSize 100k 
  
  VideoHighQuality
  
  </stream>

  and the way ffmpeg is feeding :

  ffmpeg -rtsp_transport tcp -i "rtsp://admin:admin@192.168.1.12:554/cam/realmonitor?channel=1&subtype=0" -vcodec copy -acodec copy "http://192.168.1.101:8090/test.ffm"

  Resulting video is Very pixelated and it differs from the real image.

  Cameras’ configuration are as follows :

  Resolution: D1 (704*480)
  
  FrameRate: 3
  
  BitRate: 256k
  
  BitRateType: Variable

  Is there anything i’m missing or doing wrong ?

  Thanks in advance for any help
