• Use FFMPEG to stream images from one client to another through IIS (or other) server

  20 avril 2012, par eselk

  I'm new to FFMPEG and maybe I should post this in their forums, but you guys here seem to know everything, so here goes. I have a client app that takes screen shots and saves them as images (256 color bitmaps currently, can change if needed), it does this at a rate of about 4 fps. I currently use my own socket code written in C# to push these to my socket server (also C#) running on a Windows 2008 server. That server then sends these images out to several clients that display them as they are received and also buffers them to allow for rewind, pause, etc, like a DVR. My current format requires approx 100KB per frame, and thus only works for a very small number of clients.

  I started looking at FFMPEG and the compression with MPEG1 and especially MPEG4 is amazing, and so is the quality. What I'm looking for is a basic guide, tutorial, or steps, to produce something similar to my current design, but using FFMPEG and actual video streaming. Ideally the player side could be something like Flash or anything that is easy to embed in a .NET WinForm (or a browser control I can host in the WinForm), and it would need to support buffering still so they can pause and rewind (about 5 or 10 mins, which seems like a lot, but remember this is only 4 fps and 256 color, about 1 or 2 MB per min in my testing).

  I see that FFMPEG, the command-line utility, and I assume the API, even has options for posting to a server via UDP or TCP, so maybe I'll use that instead of my own socket code. Ideally my app would feed images to FFMPEG library at a rate of 4fps as they come from the screen-shot unit, and it would send these up to my IIS server (or another server ?) which would then server them to client(s) that could use them similar to a YouTube video.

• Where to get an up to date php_ffmpeg.dll

  25 avril 2015, par Heidi

  I have Windows 2008 R2 64 bit.
  I have installed ResourceSpace 7.1.6513 which requires PHP & FFMPEG. This is not a ResourceSpace question.

  I have installed PHP 5.4.40 VC9 x86 non thread safe (as advised by ResourceSpace wiki & GG).
  I have installed FFMPEG version N-71664-gcd69c0e (64 bit static)

  Now it seems that FFMPEG and PHP need to have a php_ffmpeg.dll to work in Windows.
  Is that true ?

  If so, where do I get one that will work with my FFMPEG & PHP ? I have looked here and followed old threads, and have found random php_ffmpeg.dlls but I cannot confirm that they are compatible.
  The file taht I found, I have put it c :\php\ext and updated php.ini with extension=php_ffmpeg.dll

• configure : Simplify cygwin/mingw/msys code

  configure : Simplify cygwin/mingw/msys code
  Avoids some code duplication.
  Also drop the -mno-cygwin check since that option was removed back in 2008.
