CEA-608 renderer support
Recently some CC support has been added to gstreamer for CEA-708 but it seems CEA-608 support is still missing.
I've built the latest git master and tried playing a sample video which includes CEA-608 CCs. Using gst-play, video is shown fine, but CCs are not rendered and I'm getting the following error on the terminal output:
0:00:00.120853554 10567 0x7fd99400ae30 ERROR playbin gstplaybin2.c:3561:pad_added_cb: unknown type closedcaption/x-cea-608 for pad uridecodebin0:src_1
It would be nice to have better support for CEA-608 in addition to CEA-708.
