Good morning,
I have to write a karaoke solution with FFmpeg libav libraries for a
project of mine and I have found OggKate subtitles a good choice to
implement such solution and I am thinking of writing a Kate demuxer and
decoder along with a filter that will use OpenGL to render Kate subtitles
capabilities on frame.
What do you think ?
There is someone interested in mentoring this proposal project ?
Or is it too overkill ?
Sincerely
Gianluca

I think I have never encountered an Ogg Kate file in the wild and I do
not know of any specific software that supports them. That makes me
think Ogg Kate is one of these dead Xiph projects and supporting it
would be a waste of time.
Which features do you require for your project?

Hi Nicolas,
I would like to add motion to subtitles like fading, scrolling, changing
colors and font size, eccetera.
Is it something that can be of public interest ?
If not, which mailing list is the most appropriate to ask support for
implementing such a thing ?
Sincerely
Gianluca

ASS already supports all this. Have you tried using it for your project?
