[mythtvnz] MythTv playback on Windows Vista

Try recording a SD recording using DVB-S or Analogue input, then see if that plays.  
To my understanding the MPEG2 and 4 are essentially incompatible, and that the audio is also treated differently.

  Thanks Andrew,

  I thought the HD was a fat mepg2 stream but I stand to be corrected as I'm new to this whole thing.

  As an update I have managed to get MythTv to connect to the database by mucking around.  I'm not sure exactly what I did but anyway this is what I get now:

  C:\Program Files\mythtv>mythfrontend
  2008-10-13 20:02:21.147 Using localhost value of ROSS-LAPTOP
  2008-10-13 20:02:21.151 Testing network connectivity to 10.1.1.10

  C:\Program Files\mythtv>mythfrontend
  2008-10-13 20:02:52.411 Using localhost value of ROSS-LAPTOP
  2008-10-13 20:02:52.424 New DB connection, total: 1
  2008-10-13 20:03:07.854 Connected to database 'mythconverg' at host: 10.1.1.10

  and then it crashes.  I've tried running as administrator to see if that helps.  It didn't.

  I'm starting to wonder if there is a configuration problem with my backend.  Is there anyway to test that it is working correctly?

Ross,

This is seperate to the problems you are having, but my understanding is 
that MythTV Player only supports MPEG2, not MPEG4 (which all of DVB-T 
feed, HD or otherwise, are in). Is this not the case?

  Hi Nick,

Thanks for the comments.  I've got a DVB-T card so I guess the 
playback will mostly be HD.

Thanks for posting the links to the windows versions of MythTV.  I've 
tried both versions posted but am having trouble getting them to 
connect to the backend.  I've set the parameters in the mysql.txt file 
but I don't think that its reading the file as everytime the output 
says that its trying to connect to the local host:

C:\Program Files\mythtv>mythfrontend
2008-10-13 19:04:20.825 Unable to read configuration file mysql.txt
2008-10-13 19:04:20.836 Empty LocalHostName.
2008-10-13 19:04:20.838 Using localhost value of ross-laptop
2008-10-13 19:04:20.845 New DB connection, total: 1
2008-10-13 19:04:21.849 Unable to connect to database!
2008-10-13 19:04:21.852 Driver error was [1/2003]:
QMYSQL3: Unable to connect
Database error was:
Can't connect to MySQL server on 'localhost' (10061)

QSqlQuery::exec: database not open
QSqlQuery::exec: database not open
2008-10-13 19:04:22.911 DB Error (KickDatabase):
Query was:
SELECT NULL;
No error type from QSqlError?  Strange...

My mysql file is:

[#]
DBHostName=10.1.1.10
DBHostPing=yes
DBUserName=mythtv
DBPassword=ftd2ZZTv
DBName=mythconverg
DBType=QMYSQL3
LocalHostName=ROSS-LAPTOP

So it looks to me like its not reading the mysql.txt file at all.  
I've tried renaming the file to see if it comes up with a different 
error (like cannot find mysql.txt) but the output is the same which 
makes me think its not reading the file at all.  I've tried removing 
the .txt extension also but no difference.  Any ideas on how to test?

Also with regard to using MythTv Player, it seems from Simon's post 
that MythTv Player uses its own codecs so that might be why it can't 
access the audio stream (since I think Paul's patches affect the audio 
codecs).

In terms of connecting using a live CD it connects partially as its 
possible to view the recordings but if you try and play them it fails 
saying the backend is not available.  However I don't really want to 
pursue this avenue as I'd rather be able work within windows and not 
reboot.

I've also tried using qemu and the live CD iso but I can't seem to get 
the networking correct for qemu to access network...  Also not a 
desirable method.  I'm glad that someone has released a compiled 
version of MythTv for windows and if I can get it to work that would 
be the best solution.

      Hi Simon,

Windows Vista is what I am running.

        There is a thread pointing to windows binaries here:

http://www.gossamer-threads.com/lists/mythtv/users/329417

However they are a little old to incorporate the changes made by Paul
Kendall if you are after DVB-T.

      At the moment I can play the files through mythweb using VLC media player or
Windows Media Player.  VLC does the best job and you can deinterlace as
well.  However some recordings are laggy and drop frames or have audio
problems.  It doesn't seem to make a difference if I download them to my
laptop either.  I'm wondering if its some content protection mechanism in
Vista that can't process the high def video fast enough.  Or it is a codec
issue.

        what codecs are you trying to play? What exactly is the content? ie
where did mythtv get it from? Is it analogue, or DVB-S or DVB-T? All 3
will be using different audio (and video) codecs.

      I've tried the latest stable (4.something) and development versions
of Myth Player (5.0) but have the issue with the audio stream not being
found.  I was just wondering if anyone else is running a windows frontend
with FreeviewHD and what they've done.  I've also tried running a live-CD of
Mythbuntu but it doesn't seem to connect properly either.

        "It doesn't seem to connect properly" is a bit unscientific. What are
your symptoms and error messages?
