Return more values to the hook

[yasoob]

Currently the hook looks like this

def add_progress_hook(self, ph):
        """ ph gets called on download progress, with a dictionary with the entries
        * filename: The final filename
        * status: One of "downloading" and "finished"

        It can also have some of the following entries:

        * downloaded_bytes: Bytes on disks
        * total_bytes: Total bytes, None if unknown
        * tmpfilename: The filename we're currently writing to
        * eta: The estimated time in seconds, None if unknown
        * speed: The download speed in bytes/second, None if unknown

        Hooks are guaranteed to be called at least once (with status "finished")
        if the download is successful.
        """
        self._progress_hooks.append(ph)

This is the downloader > common.py file.

What I would like is that the hook should return more values like the thumbnail url and the title ( more specifically the values returned by the extractor ). Is it possible to implement this feature. What I am doing is that I am making a GUI for youtube-dl in PyQt and want to access these values in a single run. Another way could be to first run youtube-dl with -g and other switches and then download the file in another run but I want to run youtube-dl only one time. If there is another way then do tell me.

The GUI is under heavy development and is available at https://github.com/yasoob/youtube-dl-GUI

Instead of sending this info each time, I would send it just once in YoutubeDL.process_info before it starts writing things to disk and downloading the video.

You can read the info by using the info.json file, since you know the video filename, you can easily load the information.

can you give a simple example?
