New DVB subtitle filter (TsReader based) (2 Viewers)

[Damandan]

Hello,
Could someone confirm that when watching UK BBC1 I should be getting both teletext and DVB Subs?
Teletext subs work fine both on live TV and on recordings, but there are no DVB subs, neither using Mediaportal and TsReader, nor using VLC (also only teletext).
Clips that I have downloaded from the ftp site (BBC recording) display both types of subtiles using the "L" key, so I think my TSReader side is correctly set up.
Thanks for any help
Using all CVS builds from 11/11

Well, here in Holland we have BBC One (London?) on digital cable and the only subs that I get are the Teletext subs (With the different color text for every different voice, and the black bars around the text)

Ziphnor, sometimes I seem to get following errors. Unfortunately I don't have any recording that could be used to reproduce the issue:

ExceptionType: System.ArgumentException
Message: Source array was not long enough. Check srcIndex and length, and the array's lower bounds.
Source: mscorlib

Stack trace:

Apart from the slow channel changing issue in the current SVN I found another issue...
As soon as I tune to a channel with dvb-subs on either regular SD or HD, mp will crash.
If I disable the plugin in mediaportal.xml I have no issues at all except for no subs ofc.

Most noticible is this error:

I decided to provide the whole log as I'm pleagued with crashes, and maybe it's all related to this

Looks like another broadcaster that cant stick to the standards... *sigh*. Its one of the sanity checks that are failing, ignoring the problem in the code will probably work, but its scary none the less.

I will need a sample that when played exhibits this behavior.

I'm uploading a part of "Oceans in glass-2007-11-15-11_00.ts", from NGC HD.
This is one of the channels with dvb subs that almost always crashes, but recording goes ok.
Not sure how much of file you need, or maybe even all of it, maybe even another recording, just tell me.
Will upload a regular SD recording later.

Uploading "How to Succeed in Business Without Really Trying-2007-11-17-8_50.ts", two different subs in this one, and this is such one that crashed, even when I try to play it from my recordings it crashes mp, even now.
So this one should be the ideal recording to test what's up with these subs.
If you like I could make a recoding of one of those "boxed" subs too, though rarely used on any of the channels I got.

What I have seen is that DVB streams are more and more out of specs

Boxed subs used on BBC2, on this recording, in the first part they're really messed up.



Ultimate getaways_ Nature beaches-2007-11-17-11_00.ts

Two subs in these, both get rendered pretty bad, one to big the other one blown up.
Plus this is such a recording that makes mp crash, I just can't tune to DC HD though I can record the stream.


If you need a certain record of a stream just ask either here or on irc.

Is it impossible to integrate this thingy into next MP release? Working out of the box so every user wouldn't have to do the installing again and again?

This is what i have done so far:

1) Installed MediaPortal 2.3.0
2) Installed Tv Engine nightly build, latest version when it was 1.12.2007
3) Installed the Microsoft update whatever it does
4) Put the line in MediaPortal.XML

Whats wrong above?

You need to use TSReader either by creating a text file on c:\ called usetsreader.txt, or by installing any SVN for MP 0.2.3.0 (16540 or later).
You also need to install the TV Plugin that came with TV Engine.

Thank you, I'll try that tomorrow, and sorry for a quickly made post, I didn't make any research about the subtitle issue. I actually installed the TV plugin but I noticed no changes at all in configuration utility but maybe that's the way it's supposed to work.

Great work on 0.2.3 version though, everything works truly great =)
