python - 检测具有 Youtube 播放限制的视频

Question

我正在使用 python 开发网络服务，我想过滤掉无法在 youtube 页面之外播放的视频。

点赞此链接 [https://www.youtube.com/v/SC3pupLn-_8?version=3&f=videos&app=youtube_gdata] 你必须在 youtube 页面上观看视频，是否有任何方法可以过滤哪些视频属于同一类别。所以我只选择那些可以不受限制地播放的视频。

import gdata.youtube.service
#------------------------------------------------------------------------------ 

yt_service = gdata.youtube.service.YouTubeService()
yt_service.developer_key = 'YOUR API DEVELOPER KEY'

count=0

def PrintEntryDetails(entry):

    if entry.media.category[0].text == "Movies" :
        global count
        count = count + 1
        if  entry.noembed != None:
            print 'Video embedding not enable: %s' % entry.noembed.text
        else :
            print "entry embedable"

        print 'Video title: %s' % entry.media.title.text
        print 'Video category: %s' % entry.media.category[0].text
        print 'Video published on: %s ' % entry.published.text
        print 'Video description: %s' % entry.media.description.text
        if entry.media.private != None :
            print entry.media.private.text
        else :
            print "Right not found"          
        if entry.media.keywords :
            print 'Video tags: %s' % entry.media.keywords.text
        print 'Video watch page: %s' % entry.media.player.url
        print 'Video flash player URL: %s' % entry.GetSwfUrl()
        print 'Video duration: %s' % entry.media.duration.seconds        
        # For video statistics
        if entry.statistics :       
            print 'Video view count: %s' % entry.statistics.view_count
        # For video rating
        if entry.rating  :    
            print 'Video rating: %s' % entry.rating.average
        # show alternate formats
        for alternate_format in entry.media.content:
            if 'isDefault' not in alternate_format.extension_attributes:
                print 'Alternate format: %s | url: %s ' % (alternate_format.type,
                                                     alternate_format.url)
        # show thumbnails
        for thumbnail in entry.media.thumbnail:
            print 'Thumbnail url: %s' % thumbnail.url        
        print "@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@"
    else :
        pass

    counter = 0    
    for entry in feed.entry:        
        PrintEntryDetails(entry)
        counter = counter+1
        #print counter

一般的答案是在执行搜索时使用 format=5 参数:https://developers.google.com/youtube/2.0/reference#formatsp

这将从搜索结果中完全禁用嵌入的视频中过滤掉。

也就是说，有些视频启用了嵌入，但只能在特定区域或嵌入到特定域时播放。

要处理区域限制，您应该将 restriction= 参数设置为适合您的用例的参数，如 https://developers.google.com/youtube/2.0/reference#restrictionsp 中所述。

不过，无法从具有域级嵌入限制的搜索结果中排除视频。
