Hello,

I'm using this api, and I would like to know if it is posssible to have an ".mp3" extension with getbestaudio() function.

Thanks

I'm trying to download a video to a specific folder using the code below -

def dlVideo(url):
    video = pafy.new(url)
    best = video.getbest()
    dlPath = "/vid/" + best.title + "." + best.extension
    best.download(quiet=False, filepath=dlPath)

It shows me this when I run it -

File "dl.py", line 37, in dlVideo
    best.download(quiet=False, filepath=dlPath)
File "/Users/achalv/Desktop/Projects/pafy/pafy.py", line 746, in download
    outfh = open(temp_filepath, fmode)
IOError: [Errno 2] No such file or directory: u'/vid/Funny Cricket Wonders and Blunders, (Part 10 , Run Outs).mp4.temp'

Works perfectly as long as I don't specify a custom filepath for the download.

Trying to figure out what's wrong, and if it's an issue on my end.
Thanks!

Hi,
sometimes i get a error, try to run the next line and see if you get an error after some time:

I have this error when try to open https://www.youtube.com/watch?v=qHQzp0C1HsA

For some video there's a subtitle(s). e.g.

https://www.youtube.com/watch?v=McLq1hEq3UY

You can click CC button in the right-bottom corner in video player for captions. And there may be captions of different languages .

Technique details

1. Get ytplayer.config.args.ttsurl from watchv page if it's present.
2. Use "%s&type=list&tlangs=1&fmts=1&vssids=1&asrs=1" % ttsurl as url to fetch caption(subtitle) language list. (You can get language code list and caption format list)
3. Use "%s&type=track&lang=en&name&kind=asr&fmt=1" % ttsurl as url to fetch real caption(subtitle) where lang, fmt key could be used to specify the language and format of the caption.

Difficulty

I find you've already fetched the watchv page in your get_js_sm function. So there will be a dilemma .

1. If I do parsing ttsurl in get_js_sm function, I will not be able to get ttsurl anywhere other than in Stream class(I don't want to fetch subtitles in Stream class).
2. If I write another function other than get_js_sm function, I need to fetch watchv page again and it's a waste of time.
   So ... any suggestions?

I tried this simple test.py code

import pafym

plurl = "http://www.youtube.com/playlist?list=PLBDA2E52FB1EF80C9"
playlist = pafym.get_playlist(plurl)

for n in range(0, 41):
    playlist['items'][n]['pafy'].getbest().download()

but pafy raised

Traceback (most recent call last):ived. Rate: [4078 KB/s].  ETA: [0 secs]
  File "test.py", line 11, in <module>
    playlist['items'][n]['pafy'].getbest().download()
  File "C:\Python27\lib\site-packages\pafy\pafy.py", line 769, in download
    os.rename(tempfname, fname)
WindowsError: [Error 87]

so I tried to change pafy.py line 731~738 (workaround)

from

        try:
            outfh = open(tempfname, fmode)

        except IOError:
            # remove special chars from filename
            fname = safe_filename(fname)
            tempfname = safename
            outfh = open(tempfname, fmode)

to

        #try:
        #    outfh = open(tempfname, fmode)

        #except IOError:
        #    # remove special chars from filename
        fname = safe_filename(fname)
        tempfname = safename
        outfh = open(tempfname, fmode)

and worked fine for me...

In my case, ':' caused the problem.
The temporary filepart name supposed to be

The Agricultural Revolution: Crash Course World History #1_Yocja_N5s1I_22.part

but it was

The Agricultural Revolution

then raised error.

Please download function check http://www.youtube.com/playlist?list=PLBDA2E52FB1EF80C9 by yourself. Thank you.

Got UnicodeEncodeError error when trying to download video http://www.youtube.com/watch?v=AiK1f1eHlDI
Here is a screenshot http://screencast.com/t/l7jtOfgSnDnz

There seem to be some videos where no ogg stream is available:

>>> v = pafy.new('http://www.youtube.com/watch?v=cJEfixQv8Ho')
>>> v.getbestaudio()
audio:m4a@256k
>>> v.audiostreams
[audio:m4a@256k, audio:m4a@128k, audio:m4a@48k]

I'm not sure whether that's the fault of YouTube. If it is, I think a note in pafy's documentation that that is the case and why might make sense.

E.g., https://www.youtube.com/watch?v=cWd0hCqcqLg has "Shizzy VI" for author, but Shizzy's channel slug is "CallmeSixx".

The channel slug is usually static (I don't think it's possible to update it under normal circumstances) while the channel name can be updated at any point, making it unsuitable for archival purposes.

I would like to resume a partial download, currently downloading only starts again at the beginning, even if the file is partially downloaded. I want this feature to support mobile applications were the connection may frequently drop.
I am willing to help add this feature, but currently have no time, and I am completely unfamiliar with PAFY's code base.

Hi,

I'm trying to write a script that involves grabbing a lot of YouTube data at once. The result of this is that YouTube eventually gives an error 403 due to my client making too many requests. If I was able to specify a YouTube API key that Pafy would send along with its requests, YouTube Woodgeard the client much more leeway.

I'm going to look into trying to add this feature myself (I believe in giving what I can to open-source projects), but since I'm a newbie to Python, you shouldn't count on it. :/

Thanks for the awesome library!

hi i'm using py v2.6.5
after pip install
when i'm trying to use ytdl it says there is syntax error

File "/usr/local/lib/python2.6/dist-packages/pafy.py", line 181
smap = [{k: v[0] for k, v in x.items()} for x in smap]
^
SyntaxError: invalid syntax

whould please explain whats the problem?!

hi there
why catching streams info is very slow. when i'm using -s parameter it takes about 15 seonds!
On the other hand downloading directly is much faster (e.g. when i'm using -b parameter)

When you parse the URL argument on Windows Terminal, argparser crop everything after the first & char.

So if you try to parse something like
http://www.youtube.com/watch?feature=player_detailpage&v=Pr0kBfJz9QE#t=28
ytdl will only get
http://www.youtube.com/watch?feature=player_detailpage
and this will cause an error.

I used 3rd party tool to download 256kbps.
Also, we got 192kbps sound stream while downloading 720p+ with Pafy

Attaching related spectrograms:

I am using latest stable version of Pafy:

Python 2.7.5
Pafy==0.3.62

Thanks again and keep up the good work!

let's say I created a basic web for converting youtube videos to gifs

this is my views in django code

from django.shortcuts import render
from django.http import HttpResponse
from django.template import RequestContext
from django.shortcuts import render_to_response 
import pafy
from PIL import Image 
from moviepy.editor import *
import os

context = RequestContext(request)
    if request.GET:
         link = request.GET.get('link','')
    url = link
    try:
        video = pafy.new(url)
    except:
        return render_to_response("generated/invalid.html", context)
    video = video.getbest()
    if os.path.isfile(os.getcwd()+'\\static\\'+video.title+'.gif')==True:
        gifpath=video.title+'.gif'
        context_dict = {'staticpath':gifpath}
        return render_to_response("generated/generated.html", context_dict, context)
    video.download(quiet=False)
    clip = (VideoFileClip(os.getcwd()+"\\"+video.title+'.'+video.extension).resize(0.4))
    clip.write_gif(os.getcwd()+'\\static\\'+video.title+'.gif', fps=9, opt='optimizeplus', loop=0)
    gifpath=video.title+'.gif'
    context_dict = {'staticpath':gifpath}
    return render_to_response("generated/generated.html", context_dict, context)

it works fine, but after I convert 2-5 videos (it's random) it gives me this error,

I have to restart the django server to make it works again, strange!

the first request the terminal confirmed the video downloaded succesfully, in the 2nd request it didnt, but the video is downloaded and I can watch it. what do you think causing this? my code or the lib?

THANKS FOR YOUR TIME

It seems that the Ogg Vorbis files are malformed or maybe need to be put into an Ogg container as it isn't possible to change any tags (artist, title, album, ..).

I can play the file with VLC, but when opening the files with EasyTag (software to change tags of several formats), there's an error message: Ogg Vorbis: bitstream doesn't contain vorbis data.

Another problem is that the default Android Audio Player doesn't recognize the ogg files even though it does support them

On the contrary, downloading the webm file (with pafy) and extracting the ogg part with avconv -i ./input.webm -vn -acodec copy ./output.ogg did create a normal ogg file that could be tagged and worked as intended. (even on Android)

(Just tested: The m4a files are recognized and can be tagged.)

Hi, please check this, thanks:

Hi, I am getting the following error while running the example code from terminal

Traceback (most recent call last):

AttributeError: 'module' object has no attribute 'new'

Dear creator of pafy,
thanks for open sourcing such a useful tool.
While downloading rhymes for my kid, found that few videos are having titles with characters which are invalid for file names.
temporarily fixed in my local copy for problematic characters (\ / : * ? " < > |) as of now
filetosave = filetosave.replace("?","").replace(""","")...;

Saw few examples on Stackoverflow for better solutions using regex and str.translate.
As I'm not aware of python much, could please add code remove/replace invalid characters.

Thanks

Hello,
I'm sometimes getting errors like this one when trying to download a video :

Traceback (most recent call last):
  File "./download.py", line 43, in <module>
    best.download(quiet=QUIET, filepath = filename)
  File "/var/lib/stickshift/537000555973caa9b7000018/app-root/data/lib/python/site-packages/Pafy-0.3.42-py2.6.egg/pafy.py", line 694, in download
    response = g.opener.open(self.url)
  File "/var/lib/stickshift/537000555973caa9b7000018/app-root/data/lib/python/site-packages/Pafy-0.3.42-py2.6.egg/pafy.py", line 622, in url
    self._url = _make_url(self._rawurl, self._sig)
  File "/var/lib/stickshift/537000555973caa9b7000018/app-root/data/lib/python/site-packages/Pafy-0.3.42-py2.6.egg/pafy.py", line 464, in _make_url
    raw += "&signature=" + sig
TypeError: cannot concatenate 'str' and 'NoneType' objects

And if try again, it works like a charm.

When downloading any m4a audio stream for any video, it plays nicely in VLC and Google Play for Android. But when I add it to my library in iTunes for Mac, it is displayed in the list but tags do not show and the time/duration row says "Not available" (could be slightly different since I'm translating from Dutch: "Niet beschikbaar").

To be sure, I inspected it with MediaInfo as someone suggested on ##mac on the Freenode IRC server.

iTunes should play AAC audio streams so I have no idea why it isn't. I also used the link that can be retrieved from a Stream object and downloaded it that way, but I get the same result.

Is there a way that I could fix this besides converting it again (which would probably lose even more quality)?

Perusing through the documentation, past issues, and a little bit of the source code, I don't see any way to get the date/time that the video was uploaded.

I was able to work around it, but it might be useful for other people to be able to grab this type of information.

if i want to name the file, as the title plus some unicode string (in hebrow)

so i get the original name:
name = pafy.new('O5nWH10R_uI').getbestaudio().title

name:
u'\u05d0\u05d1\u05e8\u05d4\u05dd \u05d8\u05dc - \u05d0\u05dd \u05d0\u05ea \u05d4\u05d5\u05dc\u05db\u05ea'

now if i add to it the text u'אבג'
which is: u'\xe0\xe1\xe2'
name += u' אבג'
so now name is:
u'\u05d0\u05d1\u05e8\u05d4\u05dd \u05d8\u05dc - \u05d0\u05dd \u05d0\u05ea \u05d4\u05d5\u05dc\u05db\u05ea \xe0\xe1\xe2'

so the original name is in 4 characters for every letter, like \u05d0, and the new unicode text i added is 2 characters for every letter, like \xe0

any idea how to convert u'אבג' to same unicode format as the title?

I suggest renaming below, but will not get offended, if you don't :]

This happens in the option -b : 'ytdl -b' and version Pafy-0.3.44

but with the version Pafy-0.3.42 work well.

Thanks.

The library can't open VEVO videos. Tested with these videos:

http://www.youtube.com/watch?v=qeMFqkcPYcg
http://www.youtube.com/watch?v=lWA2pjMjpBs

When I run pafy.Pafy(video_link), it gives me:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "./pafy.py", line 267, in __init__
    self.streams = [Stream(sm, opener, self.title, js) for sm in smap]

  File "./pafy.py", line 116, in _decodesig
    funcname = m.group(1)
AttributeError: 'NoneType' object has no attribute 'group'

AFAIK, it's caused because js doesn't have any g.s||... matching string.
It doesn't happen with non-VEVO files.

we are able to fetch title and other data of youtube video. but I didn't get any option to fetch description of video using pafy. can we fetch description using pafy?

is this a bug or am i doing something wrong?

Hello,

I'm using pafy for my personal project and everythink worked perfectly untill now.
I need to read and edit audio tags after I've downloaded the file and found quite a pretty tool for this - pytaglib.It's simple and doesn't care what format your files are. Just what I need.
The problem is that when I try to read tags from file it causes an OSError: Could not read file "...."
I tried with file, which isn't downloaded by pafy and it works.
So I guess there is some kind of corrupting the tags data, I don't know.

I'm not sure where the problem is: whether in pafy or pytaglib, so I decided to create an issue for both of them, hoping someone will come up with an idea.

Kind regards,
dragonaotor

PS: Great tool btw.Good work.

Hello,

The error appears on a debian 7 wiyth python 2.7.3, I tried on a ubuntu 14.04 machine with python 2.7.6 (A c9.io workspace) and it works. Strange, seems to be only a minor version change...
Thanks in advance

You can set custom start and endtimes for videos in youtube playlists, they are luckily included in the playlist-json data:

In [44]: j = json.load(open('/tmp/list_ajax')) # list_ajax, simply g.urls['playlist'] downloaded

In [45]: v = j['video']

In [47]: [e for e in v if 'Summertime' in e['title']]
Out[47]:

These start and end keys do not exist in the json data if they are not set. My proposal, include them anyways but with start set to 0 and end to length_seconds.

I will probably submit a pull-request in the next hours/day(s), since I need that.

When Pafy try's download this video:
AGIR - "Alma Gémea" - http://www.youtube.com/watch?v=XCBygZhSEws
Because the name of video have a special character "é", the download fails.

My solution until now is:
sudo nano /usr/local/lib/python2.7/dist-packages/pafy.py

comment line63

print "-Downloading '{}' [{:,} Bytes]".format(self.filename, total)
