why are my local video files (mp4) not playing on chrome ?

1er juillet 2019, par cerr

I have some video files. Initially they were .mkv and I have converted them to .mp4 as they were not playing in chrome.

I just drag-and drop them onto a Chrome tab, in an attempt to stream them to my Chrome Cast device on my TV.

I’ve converted them using the following command ffmpeg -i input.mkv -codec copy output.mp4 on Linux. If I load either, the mp4 or the mkv in VLC they play just fine. How do I fix that so that I can cast them to my Chrome Cast ? I’ve also tried to drag & drop them onto Chrome running on a Windows machine - am getting the same result though.

I can't compile ffmpeg, don't know how to install sdl2 properly

11 mai 2019, par woopwoop399

I’m compiling ffmpeg, on windows, with mingw-w64, and I need SDL2 so that the ffplay in ffmpeg compiles. I installed mingw-w64 using the web installer, I installed msys (to run the ./configure that comes with ffmpeg) using the all in one package provided by mingw-w64. I installed SDL2 by downloading dev binaries from their site and running make native in msys.

So, it seems SDL2 isn’t installed properly or something.

Here is the problematic part in ./configure :

if enabled sdl2; then

    echo "SDL2-1"

    SDL2_CONFIG="${cross_prefix}sdl2-config"

    test_pkg_config sdl2 "sdl2 >= 2.0.1 sdl2 &lt; 2.1.0" SDL_events.h SDL_PollEvent

    echo "SDL2-2"

    if disabled sdl2 &amp;&amp; "${SDL2_CONFIG}" --version > /dev/null 2>&amp;1; then

        echo "SDL2-3"

        sdl2_cflags=$("${SDL2_CONFIG}" --cflags)

        sdl2_extralibs=$("${SDL2_CONFIG}" --libs)

        echo "SDL2-config ${SDL2_CONFIG}"

        echo "SDL2-cflags ${sdl2_cflags}"

        echo "SDL2-libs ${sdl2_extralibs}"

        test_cpp_condition SDL.h "(SDL_MAJOR_VERSION&lt;&lt;16 | SDL_MINOR_VERSION&lt;&lt;8 | SDL_PATCHLEVEL) >= 0x020001" $sdl2_cflags &amp;&amp;

        echo "SDL2-4" &amp;&amp;

        test_cpp_condition SDL.h "(SDL_MAJOR_VERSION&lt;&lt;16 | SDL_MINOR_VERSION&lt;&lt;8 | SDL_PATCHLEVEL) &lt; 0x020100" $sdl2_cflags &amp;&amp;

        echo "SDL2-5" &amp;&amp;

        check_func_headers SDL_events.h SDL_PollEvent $sdl2_extralibs $sdl2_cflags &amp;&amp;

        echo "SDL2-6-final" &amp;&amp;

            enable sdl2

    fi

    if test $target_os = "mingw32"; then

        sdl2_extralibs=$(filter_out '-mwindows' $sdl2_extralibs)

    fi

fi

This is the result of it, it never gets to SDL2-6-final and enable sdl2

SDL2-1

SDL2-2

SDL2-3

SDL2-config sdl2-config

SDL2-cflags -I/usr/include/SDL2 -Dmain=SDL_main

SDL2-libs -L/usr/lib -lmingw32 -lSDL2main -lSDL2 -mwindows

SDL2-4

SDL2-5

This is the sdl2 installation log :

And this is what happens when I just comment out that last check in ./configure and enable sdl2 anyway :

I tried using msys2 instead, it compiles, but the debugger there doesn’t work for some reason. I need to run the source code of ffmpeg in debugger to have a chance of understanding anything there. I need to use the combination of codeblocks and gdb, and programs compiled with msys2 use weird pathnames like /c/bla/bla/bla/main.c, and codeblocks is righteously weirded out by that. The mingw-w64 uses more sane pathnames, I just checked that.

Checked ffbuild/config.log, the problem is here :

`c:/Program Files/mingw-w64/x86_64-8.1.0-win32-seh-rt_v6-rev0/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lSDL2`
