Decoder plugin for Kate streams - comments ?

Hi,

I've been adding a decoder for Kate streams to xine, which I'll now port to
the 1.2 branch, but I thought I'd send it here for comments now that it's mostly
there. Note that the patch is not meant to be finished and cleaned up yet. It
also contains a few fixes to other stuff which I'll separate at some point.

Things of note:

- A new event for synced text - this is useful, for instance, to send audio
 players synced lyrics (I have this working in xine-ui and Amarok)

- The SPU decoder, if any, is now updated from the audio decoder (only
 enabled for Kate at the moment, as I expect breakage in plugins which
 do expect to have a video out)

More info about the Kate format:

Comments welcome

Thanks

Hi,

here's the patch ported to xine-lib 1.2.

There weren't any comments so far, I'd be particularly interested in:

- would this plugin be accepted ?

- is the change to update selected SPU plugins in the audio decode OK
with devs ?

- is the new XINE_EVENT_SYNCED_TEXT fine to add ?

Thanks

More likely for 1.2 than 1.1; for now, I've added this to the 1.2 patch
queue. (I'm not seeing anything obvious which signals anything other than ABI
extension, so it's probably fine for 1.1.)

Seems fine...

That too.

OK, thanks.

I'll dust up this patch and send an updated one soon, as there's
something I need to change wrt positioning of DVD style images
when the video was rescaled at encoding time.

While there, I've seen references to a possible future BGRA OSD - this
would make a fair amount of this patch obsolete, as I'd probably be able
to use libtiger, a rendering library for Kate streams that uses Pango and
Cairo - hence needing a RGB buffer).
Is this something that's likely to appear soon ? Using libtiger would make
the patch much simpler (all the text manipulation goes) as well as give
a much higher quality to the rendering.

Thanks

And here it is. It entirely replaces the previous one.

Thanks
