• fluent-ffmpeg error : ffmpeg exited with code 1 : At least one output file must be specified

  18 septembre 2023, par 김동환

  I'm trying to create a simple video from several images on node js.

  


  const ffmpeg = require('fluent-ffmpeg');

ffmpeg().input('input.txt')
.inputOption(["-f concat"])
.outputOptions("-c:v libx264 -r 30 -pix_fmt yuv420p")
.output('output.mp4')
.on('start', (commandLine) => {
console.log(`FFmpeg command: ${commandLine}`);
})
.on('end', () => {
console.log('completed');
}).on('error', (err) => {
console.error('error occurred: ' + err.message);
}).run();


  


  and input.txt is

  


  file 'test1.png'
duration 2
file 'test2.png'
duration 30
file 'test3.png'
duration 4


  


  I don't know why but this code doesn't work. but if i copy and paste the code from $commandLine, it works !!??

  


  PS C:\\Users\\donghwan\\Documents\\GitHub\\create_video\\src\> node test.js
FFmpeg command: ffmpeg -f concat -i input.txt -y -c:v libx264 -r 30 -pix_fmt yuv420p output.mp4
error occurred: ffmpeg exited with code 1: At least one output file must be specified

PS C:\\Users\\donghwan\\Documents\\GitHub\\create_video\\src\> ffmpeg -f concat -i input.txt -y -c:v libx264 -r 30 -pix_fmt yuv420p output.mp4

and so on...


  


  I'm so confused and i tried to find any other reason for this but i couldn't find anything.

• How to compile ffmpeg for Windows statically with MSYS2 environment ?

  17 janvier 2024, par username

  I want to build myself standalone statically linked ffmpeg binaries for Windows from official git source code with MSYS2 environment tools. But every time I get .exe file dynamically linked to mingw libraries that crashes with "The application was unable to start correctly (0xc000007b)" error even if I put required libbz2-1.dll, libiconv-2.dll and libwinpthread-1.dll libraries in it's folder.

  



  I'm running MSYS2 environment with

  



  msys2_shell.cmd -mingw64


  



  line, and use mingw64/mingw-w64-x86_64-gcc 8.2.1+20181214-1 compiler package. Then I run ./configure with

  



  ./configure --pkg-config-flags=--static --disable-shared --enable-static


  



  line - the best options I have googled at all my efforts. Then proceed with general

  



  make
make install


  



  sequence.

  



  As a result, I get binaries that run smoothly in MSYS2 environment itself, but when I run it from host Windows explorer or cmd, first of all it ask for libbz2-1.dll, libiconv-2.dll and libwinpthread-1.dll libraries and when I put them in binaries' folder, they crash with "The application was unable to start correctly (0xc000007b)" error.

  



  I've asked about this case at official https://ffmpeg.zeranoe.com/forum/viewtopic.php?f=5&t=6439 forum but still have no response for already 5 days.

  



  Regarding dynamic linking libraries somehow I got bandaid solution with removing *.dll.a files from mingw64\x86_64-w64-mingw32\lib folder. But it looks not very clean for me. I wish to know if it is possible to do static linkage with some compiler/make/linker parameters or with editing ./configure or Makefile files somehow ?

  



  Also 0xc000007b error still remaining.

  



  I've managed to have desired result with media-autobuild_suite based on the same MSYS2 environment, so I know it is possible to do this somehow. But I'm very new to all this *nix things so don't understand it's bash script at all, not to mention it is pretty sophisticated by itself. The only thing I see it's producing correct ffmpeg executables running under native Windows environment not requiring dlls listed above.

  



  According to all guides in internet I found at the moment, I should get standalone Windows executables with this toolset, but it just don't work and I'm stuck. Please, help.
