The concat protocol ([1] [2]) doesn't seem to work.

ffmpeg -i concat:0.ts|1.ts|2.ts -c copy output.ts
ffmpeg -i "concat:0.ts|1.ts|2.ts" -c copy output.ts
ffmpeg -i concat:0.ts\|1.ts\|2.ts -c copy output.ts
ffmpeg -i "concat:0.ts\|1.ts\|2.ts" -c copy output.ts yield concat:0.ts|1.ts|2.ts: No such file or directory "concat:0.ts|1.ts|2.ts": No such file or directory concat:0.ts\|1.ts\|2.ts: No such file or directory "concat:0.ts\|1.ts\|2.ts": No such file or directory respectively.

To Reproduce E.g.:

const command = [
  '-i',
  'concat:' + Array.from({ length: 3 }, (value, index) => index.toString() + '.ts').join('|'),
  '-c',
  'copy',
  'output.ts'
];
console.log(['ffmpeg', ...command].join(' '));
await ffmpeg.exec(command);

Expected behavior The concat protocol works.

Error message is somewhat misleading, as it suggests that FFmpeg misinterpreted the input (file protocol vs. concat protocol), whereas it's complaing about one or more missing files that are in the concat list.
