Pipe to the input of ffmpeg

[Timber1900]

Description I have a stream of a video and want to pipe it to the input of the ffmpeg process. On widows, using static ffmpeg and child process I can spawn a ffmpeg process and use the built in pipes to to pipe the stream to, but I dont know if theres something similar that can be done with this package. Using a blob as a input would also work.

Expected behavior For RUNFFmpeg tot have some sort of pipe to pipe data to.

Current behavior There doesnt appear to be any sort of feature

        : join(path, `${fixedTitle}.${ext}`),
    ],
    {
      windowsHide: true,
      stdio: ['inherit', 'inherit', 'inherit', 'pipe', 'pipe', 'pipe'],
    },
  );
  // @ts-expect-error
  audio.pipe(ffmpegProcess.stdio[4]);
  // @ts-expect-error
  video.pipe(ffmpegProcess.stdio[5]);

See the Pipe Support page written for MobileFFmpeg. You can do the same things in react-native-ffmpeg.

I can create the pipe this way but cant seem to find a way to push data to it, on my windows app I used the fetch api to get the video data as a stream and used the Stream.pipe() method, however when I attempt to do the same in react native there seems to be no stream included in it, (it says that there is no body attribute of type Response). Using axios I can get the data as a blob, however the Blob.asStream() method also doesnt exist, and I cant seem to find any other way to pipe this data to the created pipe.

Thanks for the help.
