These are the builds of FFmpeg used by Universal Media Server.
I started using the Zeranoe builds, which are awesome, but I wanted to apply some patches so here we are 🙂

  1. 1st Thanks for these builds!
    2nd What patches do you apply? / What is the difference to Zeranoes builds?

  2. btw. do you plan to do 32&64bit builds like Zeranoe does?

    @Selur: 1) You’re welcome 🙂
    2) Right now I have just changed some default values. As always, the code is available if you are curious about more specifics 🙂
    3) No, I probably won’t do 64-bit builds. My main interest in MPlayer and FFmpeg is to make UMS better, and UMS shouldn’t use 64-bit binaries, so there’s no benefit to me to make them 🙂
    4) Thanks for confirming that the MEncoder DTS bug isn’t in SB42.

  4. Excellent man. Thanks for adding RTMP support for FFmpeg. CR Takeout subtitles are working perfect with this build now. 🙂

    @kuroukage: Great, and thanks for the help 🙂 UMS 2.4.1 will be released soon with the new binaries

  6. Not sure if it really interests you, but ffmpeg doesn’t work on win2k (I know it’s old)

    When trying to start ffmpeg it throws:
    ffmpeg.exe – Entry Point Not Found
    The procedure entry point _aligned_free could not be located in the dynamic link library msvcrt.dll.
