Hi all,
I've been doing some looking at the suggested closed captioning project, and this is what I see as being required:
- get mpeg2dec extracing the user data packets from DVD VOB
- create a dynamic pad if CC data exists and pass it to new, improved vbidec plugin (old code, so will probably need some major work)
- vbidec needs to pass to decodebin
- decodebin needs to detect and handle new pad for CC
- playbinbase needs to detect and handle dynamic pad from decodebin for CC
- use textbin in playbin to overlay CC on video
This is what I gather from a quick read of some of the code, using gst-inspect, and the very helpful thread at
http://thread.gmane.org/gmane.comp.video.gstreamer.devel/19727. Of course, I may be way off. Hopefully, not :) But, that's exactly why I'm writing: to get help from the ones who eat, sleep, and breath this stuff!
Thanks,
Neil
