Mart Raudsepp	aca7237878	dvbsuboverlay: Make the libdvbsub callback handler responsible for memory cleanup ... We want to allow queueing of raw region image data in the gst plugin side, and keep the data around until we pop the item from the queue. So make the callback handler responsible for memory cleanup, if one is installed.	2010-12-08 16:30:09 +01:00
Mart Raudsepp	4a68decb52	dvbsuboverlay: Work with GstClockTime instead of PTS for subtitle timing ... Abuse libdvbsub PTS tracking to just store our running time in it, to get it back in the callbacks. As GStreamer does its own PTS handling behind our back (especially for video), we should just sync with video per running time, not try to do it with PTS, which doesn't seem well accessible for video chain. We can later relabel dvb-sub.c pts naming convention if wanted, it's just passing along guint64 values, which GstClockTime fortunately is too. The current idea is to collect the regions returned by the callback into a FIFO buffer and pop and pre-render the top one into a separate quick-to-blend cached format, which is then appropriately blended in the video chain until the next one on top of the stack reaches the video chains running time (or the fallback timer hits).	2010-12-08 16:30:09 +01:00
Mart Raudsepp	316cd44c8d	dvbsuboverlay: Add FIXME note about non-constant PTS for a display set handling.	2010-12-08 16:30:09 +01:00
Mart Raudsepp	7cab41013e	dvbsuboverlay: Remove dvb_sub_feed() API ... GStreamer will only use dvb_sub_feed_with_pts, as it has its own PES filter to do the header parsing.	2010-12-08 16:30:09 +01:00
