关于Kodi字幕插件的开发
最近把家里的HDPC终于改成Debian了，起初一直在Windows 10下，但经过长时间的使用，装着E5200芯的老机器终于拉不动了，启动都要卡半天。思索了半天，干脆换到了Debian下。没去试现在的安卓X86版本和凤凰系统，是因为不想过于折腾了，虽说Debian并不是个好的娱乐平台，但好在安装Kodi倒是很方便对这个系统也比较熟悉，而我也仅仅用它就可以了。
安装的是Debian 9.4版本， Kodi是17.6的。设置什么的轻车熟路，电影、电视、直播啥的都基本没问题，但找遍了网上现有的中文字幕插件，就没一个可以用的，有的说是给15的版本可以用，但我没试而且也不想换版本。没办法了，只有自己改吧。
在这里真要吐槽一下Kodi的官方资料，英文的不说，而且是积极的简单，什么函数基本上就是一句话解释，连示例都没有一个，不过还好，综合了很多现成的源码，基本上了解了它字幕插件的思路和一些函数方法。代码是基于网络现有的插件基础上改的，字幕来源于字幕库。
首先是搜索函数，一番查验这个到是简单，原先的代码找不到内容是因为网站页面div的class改了，所以把bs的查找规则调整就ok了。
def Search( item ):
subtitles_list = []
log( __name__ ,"Search for [%s] by name" % (os.path.basename( item['file_original_path'] ),))
if item['mansearch']:
url = ZIMUKU_API % (item['mansearchstr'])
else:
url = ZIMUKU_API % (item['title'])
try:
socket = urllib.urlopen(url)
data = socket.read()
socket.close()
soup = BeautifulSoup(data,'html.parser')
except:
return
results = soup.find_all("div", class_="item prel clearfix")
for it in results:
moviename = it.find("div", class_="title").a.text.encode('utf-8')
iurl = it.find("div", class_="title").a.get('href').encode('utf-8')
movieurl = '%s%s' % (ZIMUKU_BASE, iurl)
try:
socket = urllib.urlopen(movieurl)
data = socket.read()
socket.close()
soup = BeautifulSoup(data,'html.parser').find("table", class_="table")
soup = soup.find("tbody")
except:
return
subs = soup.find_all("tr")
for sub in subs:
name = sub.a.text.encode('utf-8')
if name.split('.')[-1] not in ['zip','Zip','ZIP']: continue
flag = sub.img.get('src').split('/')[-1].split('.')[0].encode('utf-8')
lang = FLAG_DICT.get(flag,'unkonw')
link = '%s%s' % (ZIMUKU_BASE, sub.a.get('href').encode('utf-8'))
if lang == '英':
subtitles_list.append({"language_name":"English", "filename":name, "link":link, "language_flag":'en', "rating":"0", "lang":lang})
else:
subtitles_list.append({"language_name":"Chinese", "filename":name, "link":link, "language_flag":'zh', "rating":"0", "lang":lang})而下载函数就麻烦了一点，看原来代码是获取下载地址后直接下载，而实际上我在网站下载时发现网站使用了301重定向，并且在访问下载地址时，网站做了防爬虫处理，需要在头里带上Referer，否则系统是不会给你正确的定向地址的，经过改动的代码如下：
def Download(url,lang):
try: shutil.rmtree(__temp__)
except: pass
try: os.makedirs(__temp__)
except: pass
exts = [".srt", ".sub", ".smi", ".ssa", ".ass" ]
try:
socket = urllib.urlopen( url )
data = socket.read()
soup = BeautifulSoup(data,'html.parser')
url = soup.find("li", class_="li dlsub").a.get('href').encode('utf-8')
socket = urllib.urlopen(url)
socket = urllib.urlopen(url)
data = socket.read()
soup = BeautifulSoup(data,'html.parser')
div = soup.find('div',class_='down clearfix')
li = div.find('li')
headers['Referer'] = url
req = urllib2.Request(li.a.get('href'),headers=headers)
resp = urllib2.urlopen(req)
socket = urllib.urlopen(resp.geturl())
data = socket.read()
socket.close()
except:
return []
if len(data) < 1024: return []
tempfile = os.path.join(__temp__, "subtitles.zip")
xbmc.log(tempfile)
with open(tempfile, "wb") as subFile: subFile.write(data)
subFile.close()
xbmc.sleep(500)
lists = unZip(tempfile)
lists = [i for i in lists if os.path.splitext(i)[1] in exts]
if len(lists) == 1:
return lists[0]
else:
index = [i.split('/')[-1] for i in lists]
sel = xbmcgui.Dialog().select('请选择压缩包中的字幕', index)
if sel == -1: sel = 0
return lists[sel]经过调整，大的问题没有了，不过些小的地方，原代码里貌似是只能在Windows下用的，因为好像它是用Winrar来解压的，而我在Debian下使用，所以只能考虑Zip文件了，至于能不能用rar包还有单独的srt等文件，以后折腾吧。
def getFileList(path):
fileslist = []
for d in os.listdir(path):
if os.path.isdir(path+d):
fileslist.extend(getFileList(path+d+'/'))
if os.path.isfile(path+d):
fileslist.append(path+d)
return fileslist
def unZip(filepath):
zip_file = zipfile.ZipFile(filepath,'r')
for names in zip_file.namelist():
if type(names) == str and names[-1] != '/':
utf8name = names.decode('gbk')
data = zip_file.read(names)
fo = open(os.path.join(__temp__, utf8name), "w")
fo.write(data)
fo.close()
else:
zip_file.extract(names,__temp__)
return getFileList(__temp__+'/')总结一下啊，用惯了Python3后用2真的不习惯，并且在Kodi里测试也是非常的不方便，改动一下需要重新进入才行，经过测试在Linux和Windows下都没问题，版本从17到最新的18，至于更低的版本则没测试，接下来要把各种字幕扩展名的文件下载功能补全，等到某一天有心情折腾了再说吧。附地址：https://pan.baidu.com/s/1GxAod4Xdll-3pvM_OOru8A
更新：由于上次改的有太多的局限性，所以继续抽时间改了改，现在这个版本继续支持Linux和Windows，并且文件格式由单纯的zip扩展到rar的压缩，还包括了各种未压缩的字幕格式，由于网上并没有发现7z的字幕压缩包，所以就没有考虑这个格式了。但现在由于格式的增多，就带来了一些问题，为了这个插件的正常使用，在Windows下必须要安装WinRAR并且目录还得是C:\Program Files\WinRAR，在Linux下需要安装unrar，否则的话会下载失败，其他没有要求，注意这点即可。
