• what is the exact path to specify in php for ffmpeg for windows

  17 janvier 2014, par user3196597

  i'm new to ffmpeg..and i've been trying to figure out the exact path to specify while running it in a php exec() function the code below runs fine in terminal but not in php :

     1)c:/ffmpeg/bin/ffmpeg -y -i c:/xampp/htdocs/video/media/original.mp4 -f avi c:/xampp/htdocs/video/media/new.avi 2<&1
  
  
  
  
  
     2)c:/xampp/htdocs/video/ffmpeg/bin/ffmpeg.exe -y -i c:/xampp/htdocs/video/media/original.mp4 -f avi c:/xampp/htdocs/video/media/new.avi 2<&1

  that works fine in terminal but not in php, i think the problem is with the path specification..can anyone tell the exact path to use while working in windows,please ??

  thanks in advance friends :D

• Unable to run a program in PATH from Java code

  17 novembre 2012, par user1831004

  I am developing a Red5 media server application on a Mac (Dynamic Web Project in Eclipse). The app has to invoke FFMPEG to convert the video to a different format.

  I added "/Applications/FFMPEG" to PATH variable by running the following command in Terminal :

  echo 'export PATH=/Applications/FFMPEG:$PATH' >> ~/.profile

  When I invoke FFMPEG from terminal, it works fine. However, every time I run it from Java code with :

  Process p = Runtime.getRuntime().exec("ffmpeg");
  
  p.waitFor();

  I get the following error :

  Cannot run program "ffmpeg": error=2, No such file or directory

  I thought this might be a security limitation specific to the type of project, but even a simple Java program produces the same result. What am I missing ?

  ---

  Changing "ffmpeg" to full path of the application works, but I don't want to upload FFMPEG into the same directory as Red5 on a production server.

• Why rtp streaming of a .avi video file fails to be received ?

  14 juillet 2016, par user1914692

  In ffmpeg streamingGuide, it writes :

  ffmpeg -re -f lavfi -i aevalsrc="sin(400*2*PI*t)" -ar 8000 -f mulaw -f rtp rtp://127.0.0.1:1234 &
  
  ffplay rtp://127.0.0.1:1234

  I want to use a real video file to replace the artificial signal.
  Then I write the below at terminal A :

  ffmpeg -re -i outputFile.avi -f mulaw -f rtp rtp://127.0.0.1:1234

  it seems it is working :
  The frame information is counting. Here are information on the terminal A at the end :

  frame=  309 fps= 29 q=31.0 Lsize=     931kB time=00:00:10.30 bitrate= 740.8kbits/s     video:922kB audio:0kB subtitle:0 global headers:0kB muxing overhead 1.030813%

  When the frame at terminal A is still counting (not finished), I type the below at terminal B :

  ffplay rtp://127.0.0.1:1234

  But it does not work :
  The error information is :

  [udp @ 0x7fb370001500] bind failed: Address already in useB f=0/0   
  
  rtp://127.0.0.1:1234: Input/output error

  Why ?

  [Update 1] Following the instruction from Camille Goudeseune
  I used the foo.sdp
  The input for the ffmpeg terminal is :

  ffmpeg -re -i out.avi -f mulaw -f rtp rtp ://127.0.0.1:1235

  The terminal for ffplay is :

  ffplay -i foo.sdp

  The ffplay terminal shows a lot of error, without images.
