GUI

[Elite]

Hi,

I see that progress is being made towards making youtube-dl exposed for use in other projects, I am new to python but would definitely want to give this a try and wrap YTDL in my project. Can you pls. provide a basic example to get things started i.e. how to start a download and receive progress updates in my app ?

Thanks

[jaimeMF]

You can start with this code:

#!/usr/bin/env python

from youtube_dl import YoutubeDL

def progress_hook(pr):
    print(pr)

ydl_options = {
    'outtmpl': u'%(title)s-%(id)s.%(ext)s',
}

with YoutubeDL(ydl_options) as ydl:
    ydl.add_default_info_extractors()
    ydl.fd.add_progress_hook(progress_hook)
    ydl.download(['http://www.youtube.com/watch?v=BaW_jenozKc'])

The progress_hook function receives a dictionary with the download progress (not the extraction progress), you can use it to report the progress on a GUI.

I'll close the issue, but if you have any suggestion (or find a problem) for making integration easier, feel free to open new issues.

hi,
I'm also new to python. But I'm interested in this project could please
kindly involve me in this project..

I am getting following errors when using this with Python3.3 and PyQT5 ::

raise DownloadError(message, exc_info)
youtube_dl.utils.DownloadError: ERROR: Unable to download video webpage: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:547)>

I know this is an known issue (#883) and tried a fluke with the following ::

ydl_options = {
    'outtmpl': u'%(title)s-%(id)s.%(ext)s',
   'no_check_certificate':'True',
}

which failed including the YTDL.config (located in the root of repo clone) as below ::

// ADD PREDEFINED MACROS HERE!
--no-check-certificate

Pls. post the correct method to get past this roadblock.

UPDATE ::

The below worked -

ydl_options = {
    'outtmpl': u'%(title)s-%(id)s.%(ext)s',
    'nocheckcertificate':'True',
}

[Elite]

Stuck now at this -

 File "C:\Python33\lib\idlelib\PyShell.py", line 1318, in write
    return self.shell.write(s, self.tags)
UnicodeEncodeError: 'UCS-2' codec can't encode characters in position 51-51: Non-BMP character not supported in Tk

[phihag]

@Elite The option should be

ydl_options = {
    'outtmpl': u'%(title)s-%(id)s.%(ext)s',
    'nocheckcertificate': True,
}

However, I cannot reproduce the certificate issue, and we'll have to track down what really happens here - is your provider doing something fishy?

The UCS-2 error is a limitation of tk. Pick a toolkit that can handle all characters, or filter them out in your logger (simply pass in as 'logger' an object with a debug and an error method, then you won't have to deal with stdout and stderr). Note that our example video uses these somewhat rare characters intentionally, so for testing, you can also switch to another test video.

[Elite]

@phihag Thanks, I managed to hunt down the correct ydl_option and edited my answer above. I am very new to python, but I am sure will learn and make my way through using help :)

[jaimeMF]

@phihag Last time I tried youtube-dl running on python 3.3 in windows I got the certificate problem (I also reproduced it with Ubuntu on a virtual machine)

[grosapepe]

I'm building some kind of graphic interface for the great youtube-dl, I'm using Tkinter and python.

Anyway my gui is thinked only to help a friend who really needs to have a GUI for accessing this good binary and the program is at a real early state ( time is always my enemy!! ).

Here you have a screenshot of what I'm doing, if you feel interested let me know, we can think about a more general purpose design.

[yasoob]

Have you implemented any way to tell the progress of the download to the
user through GUI ?

[grosapepe]

yes I can get the output in this way

as I mentioned the project is really at an early state and it's' just a simple prototype for a friend.

[Elite]

@grosapepe Can you pls. share your work so we can improve upon it?

[grosapepe]

sure, which one is the best place? I mean a copy/past of my tk.py file should be enough or is there a better place where to upload files?

[Elite]

@grosapepe A copy-paste here would be fine.

[grosapepe]

here I post a real basic GUI I created in a few hours; it's just functional programming without any class implementation and built-in calls to the main YTDL classes,

I simply controlled the binary with some switches to have a fast and simple solution, much more work can be done.

                v.set("Finish!!!")
            except OSError:
                pass
        elif (v2.get() == 1):
            print idFileName
            print fileName
            os.rename(idFileName,fileName+idFileName[11:])

@grosapepe If your are going to work on it, you could create a repository, so that people can easily contribute to the code.

[Elite]

@grosapepe Thanks for sharing this but this uses Youtube-dl binary file, since YTDL can be imported as an library as shown and discussed above it would be a more preferred way.

[grosapepe]

ok, I will consider to create a space for this project; as I said it was controlling the binary and not doing internal calls to the library. Anyway it seems to be not so complicated to rewrite those calls importing the library instead. Anyone who feels to give me some help on it... :)

[ghost]

Here is mine. Uses tk and threading to update progressbar (does not deal with errors).

https://gist.github.com/pulpe/7854561

[jaimeMF]

The script posted by @pulpe seems to be a good start for using the library. If you have any question I'll happily try to help.

[grosapepe]

ok, it seems we have two nice prototypes and that's it! As I expressed also to @phihag my purpose was to create something really professional that aims to be something similar to the zenmap interface for the nmap binary.
I guess the really basic step for that purpose is to define some prerequisites and even some scatches of how the GUI would be in the beta prototype and from there starting to code on parallel inside a working group.
Consider the goodness of this contribute inserted in an open-source environment and consider also all limitations of this approach ( I mean coding in the spare time, no remuneration for this effort and all the stuff that everyone of us understand and obviously already know :)
any suggestion?

[Elite]

I managed to make a working prototype in PyQT5, pls. tell how to capture any output other then progress_hook like "Setting Language", error messages and get output for switches like -e, --get-title to populate the GUI info panel?

[phihag]

@Elite Pass in a 'logger' object to get status output. Look at the return value you're getting from the function calls, these will be the info dictionaries which you can see with -j.

[Elite]

OK got it, this works-

info = ydl.extract_info('https://www.youtube.com/watch?v=JzrbQHolJyg',False)

[ghost]

If you search github for youtube gui you find a lots of gui implementations.

For example https://github.com/chummm/ydlqt why don't we fork it?
