Twisted Pipe Two Processes With Spawnprocess

I'm trying to use Twisted with Python2.7 for piping two processes. What I'd like to do is: myImagesPipesGenerator | ffmpeg -i - myImagesPipesGenerator is outputing on stdout an i

Solution 1:

Create the pipe yourself:

read, write = os.pipe()

And then pass the file descriptors where you want the children to use them. Something like:

generatorTransport = reactor.spawnProcess(..., childFDs={1: write})
ffmpegTransport = reactor.spawnProcess(..., childFDs={0: read})
