• Why cant I feed FFServer(Linux) from FFMpeg (Windows) ?

  14 mars 2018, par Milen

  What I want to do is to stream a (only)video file from Windows 10 using RTSP. First, I tried to use webm HTTP instead. I found that ffserver is not avaiable for Windows, so I configured and run ffserver on a Linux machine (Ubuntu 16.04). Then, I downloaded pre-built ffmpeg for Windows x64 and run a ffmpeg command to feed my rtsp server. The fact is that the command didnt work on my Windows machine

  The same ffmpeg command works well if I run it in my Linux machine.

  The details are descripted below :

  ffserver.conf file :

  HTTPPort 8090                     
  
  HTTPBindAddress 0.0.0.0
  
  MaxHTTPConnections 2000

  ffmpeg command to feed server :

  ffmpeg -i video.avi http://192.168.0.119:8090/feed1.ffm

  Error thrown by Windows command line :

   Unable to find a suitable output format for 'http://192.168.0.119:8090/feed1.ffm' .
  
   http://192.168.0.119:8090/feed1.ffm : Invalid argument.

  Someone told me that Windows newest version of FFMpeg doesnt support ffm, Is that true ? I couldnt find a different format example.

• Loseless FFMPEG compression that supports windows media player

  12 juin 2018, par nmr

  I am trying to create a movie file (avi, mp4, etc as long as it support windows media player) from a sequence of png files using ffmpeg.I am using C++ "System("ffmpeg command")" to create the movie files once I create the png files (this shouldn’t effect movie creation). I was able to create a .avi file using the following command,

  ffmpeg.exe -r 30 -i frame_%7d.png test1.avi

  Once you create the file it runs in windows media player but does not run in VLC. I have realized, it does lossy compression and the movie is not that high quality (quality decreases with frame rate). I want to have lossless compression (or no compression at all) but needs to be able to play in windows media player. So I tried the following commands,

  ffmpeg.exe -framerate 30 -i frame_%7d.png -codec copy test2.avi

  This file ran in VLC but didn’t run in windows media player. Then I tried put in "-pix_fmt yuv420p" but still couldn’t get it to run in windows media player.

  ffmpeg.exe -framerate 30 -pix_fmt yuv420p -i frame_%7d.png -codec copy test2.avi

  I have also tried using "ffv1" codec and it ran in VLC but not in windows media player

  ffmpeg.exe -i frame_%7d.png -c:v ffv1 -qscale:v 0 test4.avi

  So, how do I create a lossless movie file from a sequence of png files using ffmpeg that will run in windows media player ?

• How to install PHP FFMPEG on windows 10 64 Bit

  7 septembre 2017, par PlanetHackers

  I want to install the PHP FFMPEG on my system. My system configuration is :

  OS : Windows 10 64 Bit
  XAMPP v3.2.2
  PHP v7.0.15

  I found many tutorial but nothing found working. May be due to 64 bit system. I wanted to add a watermark to a video through PHP. That’s why I need the ffmpeg extension. I also tried through Composer but did not get success.
