Can't reuse ffmpeg

Describe the bug GIVEN I load ffmpeg AND I run any command AND I run another command THEN an error is thrown

[info] run ffmpeg command: -L
Uncaught (in promise) 
{
    "name": "ExitStatus",
    "message": "Program terminated with exit(0)",
    "status": 0
}

To Reproduce

const fs = require('fs');
const { createFFmpeg, fetchFile } = require('@ffmpeg/ffmpeg');

const ffmpeg = createFFmpeg({ log: true });

(async () => {
  await ffmpeg.load();
  await ffmpeg.run('-L');
  await ffmpeg.run('-L');
})();

Expected behavior It should run both commands

I’m experiencing similar issues.

[usr-ein]

I use both the single-threaded and the multi-threaded version in my app, and dynamically switch between the two when available, and I noticed that, when using the multithreaded one (proxy_main), I can successfully run two commands await ffmpeg.run.

However, when using the single-threaded version, the first command succeeds, but the second one just hangs forever. The last message from FFMPEG’s logging is

...
[ffout] FFMPEG_END
[info] run ffmpeg command: -framerate ...

and then eternal hanging.

My solution was to: read the files from the first command into memory using ffmpeg.FS("readFile", then, await ffmpeg.exit(), then await ffmpeg.load(), then copy back the file from the previous run, plus all my other required files, and then run my second command.

This did the trick in single-threaded mode, but it’s a shame I can’t resuse the files I wrote the first time around.

Tested on ffmpeg-core version 11.4, compiled on commit 1f3461d.
