Firstly ive seen #217 and looking forward to API-ification.

In the meantime, im using subprocess to call youtube-dl, but am curious on how my code can get the download progress.

Im running it like so

p = subprocess.Popen([yt_path, "http://www.youtube.com/watch?v=%s" %(ytid),  "-o", filename ], stdout=subprocess.PIPE)
com = p.communicate()

Here after the first line, it executes youtube-dl, only when it finishes the download, the next line is executed with the shell output. Is there a way I can regularly poll the subprocess for the latest shell output so my application can know what the progress is?

I understand this has more to do with subprocess than youtube-dl, but i figured some users may have already figured it out.

You can simply read from p.stdin asynchronously. We don't make any promises about the output you'll get (that's what #152 would do), but realistically, it won't change much.
