Hi,
yesterday, I have installed the grabber from Ben Bucksch which uses the
data sources of TV-Movie to create XMLTV files. At the end, it worked, but
there are some findings I'd want to share.
1. The listings sometimes contain real unicode characters, i.e. characters
with a number outside range(256). This causes freevo not to accept the
listing. I then wrote an own function __encode in epg_xmltv.py which looks
roughly like this:
def __encode(str,code):
try:
return str.encode(code)
except UnicodeError:
result = ''
for ch in str:
try:
result = result + ch.encode(code)
except UnicodeError:
pass
return result
Then, I have replaced every occurrence of encode in epg_xmltv.py with my
own function. After that, it worked, ommitting the characters which seem
not to be displayable by freevo.
That was unnecessary. From the Python library reference::
encode([encoding[,errors]])
Return an encoded version of the string. Default encoding is the current
default string encoding. errors may be given to set a different error
handling scheme. The default for errors is 'strict', meaning that encoding
errors raise a ValueError. Other possible values are 'ignore' and
'replace'. New in version 2.0.
Basically, to get the same behaviour as you created you can just use 'ignore'
as the second argument to encode(). If you use 'replace', the character will
be replaced with '?'. I'd suggest 'replace', but that's a personal
preference.
2. The listings contain a color tag, which freevo does not know. There is
Freevo doesn't know that color tag because it's invalid. The author of the
grabber needs to fix that. In fact, you should probably tell the author to
validate the XML output against the XMLTV DTD. I highly recommend pyRXP due
to it's amazing speed: http://www.reportlab.com/xml/pyrxp.html
To use pyRXP to validate, make sure the DTD is in the current directory and
run this script on the file you want to validate:
- ---cut---
#!/usr/bin/env python
import sys, pyRXP
def handleMessage(s):
sys.stderr.write(s+'\n')
if __name__ == '__main__':
if len(sys.argv) 2:
sys.stdout.write(Must specify file)
sys.exit(2)
p = pyRXP.Parser()
p.srcName = XMLTV pyRXP
p.warnCB = handleMessage
p.parse(open(sys.argv[1]).read())
- ---cut---
3. The listings contain a Tag like rating system=FSK16/rating. It seems
that freevo has a problem with that. I deleted the handling of this tag in
epg_xmltv.py to make this work. (freevo does not seem to display the rating
anyway.
Any code using rating for anything other than straight text display should be
checking the system attribute.
4. The listings contain the time in the following format:
200309042015 CET
But this is IMHO wrong, it should be
200309042015 CEST
Then, the coding with strptime.strptime in epg_xmltv.py works correctly.
This is not necessarily a problem of freevo, but I just wanted to mention.
I have sent a mail to Ben Bucksch about that. I will also check how the
listings could be converted to the CET/CEST format.
I highly recommend using numeric timezones in grabbers. Some of the grabbers
from the official XMLTV distribution do this already and the others will be
converted soon. Some of those strings are conflicting, such as my timezone,
Canada/Atlantic, and Saudi Arabia's, both of which are 'AST'.
