    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • ffmpeg build with msys2 + VS2017 hang

    20 décembre 2019, par lucky1928

    I am using windows10 + MSVC2017 Community + MSYS2 to build ffmpeg 4.0.1 with below steps :

    1. Start a Visual Studio 2017 "Developer Command Prompt"

    2. cd into msys64 directory, and then invoke MSYS2

      msys2_shell.cmd -msys2 -use-full-path

    3. In MSYS2 shell, cd into ffmpeg build directory.

    4. run ffmpeg config command :

      ./configure --prefix=./install --toolchain=msvc

    After press enter with above command line,sounds like it hang there forever.
    never print anything out and not exit as well.

    Everything works until it gets to !%input[%x%]%! in the :inputVarious group.

    Because this is the output I get from that line :

    mediainfo --Output=Video;%Height% !x!  1>\Temp\ffmpegres1.txt

    What I’m trying to do is get the data stored in the input[x] array position and send it to mediainfo as input, so that it can get the video’s resolution, store that into the height[x] array.

    I have no idea what I’m doing wrong. Could someone help me ? Tips on how to make the code less redundant and more elegant are also appreciated.

    Obs. : I tried to recreate this in Python but I’m too much of a bad study and couldn’t get working (although what I was able to do, was done in a less janky way)

  • How to recompile with -fPIC

    15 février 2023, par user1455085

    I was trying to reinstall my ffmpeg, following this guide, on my ARM Ubuntu machine. Unfortunately, when I compile a program which uses this lib I get the following failure :

    



    /usr/bin/ld: /usr/local/lib/libavcodec.a(amrnbdec.o): relocation R_ARM_MOVW_ABS_NC against `a local symbol' can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/libavcodec.a: could not read symbols: Bad value
collect2: ld returned 1 exit status


    



    Now I would like to recompile it with -fPIC like the compiler is suggesting but I have no idea how. Any help is appreciated.
