[vdr] Plugin for MHEG (BBC RedButton service)

[John Williams]

Hello,

I have adapted the standalone "redbutton" program
(http://redbutton.sourceforge.net/) into a plugin for VDR. This allows
me to view the "Redbutton" data service broadcast by the BBC.

This is a preliminary version of the plugin and it is not robust enough
for general use, but if anyone would like to experiment with it, the
source code can be downloaded from http://pond-weed.com/redbutton/

Regards,
John Williams

great to hear that. To everyone as ignorant about MHEG as me please read
[1]. John, thank you for the screenshots on your project site.
Unfortunately MHEG is not available in Germany according to [1].

I could not find a repository on your site. I think it greatly eases the
task to provide patches. If you do not want to set one up yourself and
you need a host you could use for example [2].


Thanks,

Paul

As far as I am aware, this is only used by the BBC in the UK, and by a
few other countries. I believe some other countries use a different
system called MHP.

Most of the code was written by Simon Kilvington as a stand-alone
program, and I want to co-operate with him, so I need to talk to him
about this.

hi John!

sounds really great!
Unfortunately this is not working with my vdr 1.7.17.
Compiling all works fine as in your instructions.
But if I include both plugins with -Predbutton and -Pmheg I can't connect to xineliboutput any more. :(

Anybody knows what modifications are needed to fix this issue?

kind regards

Newsy

Did you ever get anywhere with this? I'm thinking, with both the
Olympics and Wimbledon coming up shortly, it would be useful to get
MHEG up-and-running on my VDR install, so I was going to try out your
plugin later. It would be useful to at least have a bug tracker
available so that I can raise any issues I find.

Perhaps you could create a project on http://github.com and import the
code there?

On a related note, I couldn't see a single tar on your website, so I
grabbed the source files from the http dir listing and packaged it up
as vdr-plugin-redbutton.tar.bz2 to make it easier for people to
download in one go.

I managed to compile the plugin against 1.7.27. I had to make a couple
of minor patches to cope with newer ffmpeg API changes, and to add
-lswscale (the existing Makefile 'test' to add this wasn't working)

Unfortunately the mheg plugin generates lots of bad looking entries in
my syslog :
vdr: [2918] ERROR: TS packet not accepted in Transfer Mode

And launching the 'redbutton' plugin just displayed a small quarter
sized shaded window in the top left of my screen, with no content.

So it looks like the plugin needs some updates to cope with vdr 1.7.x
and 1920x1080 resolutions

Is anyone able to confirm whether this plugin with a "full feature",
hardware decoder DVB-S card please?
