h265ccinserter

Extracts closed caption meta from buffer and inserts closed caption SEI message

Example launch line

gst-launch-1.0.exe filesrc location=video.mp4 ! parsebin name=p ! h265parse ! \
  queue ! cccombiner name=c ! \
  h265ccinserter remove-caption-meta=true caption-meta-order=display ! \
  h265parse ! avdec_h265 ! videoconvert ! cea608overlay ! queue ! autovideosink \
  filesrc location=caption.mcc ! mccparse ! ccconverter ! \
  closedcaption/x-cea-708,format=(string)cc_data ! queue ! c.caption

Above pipeline inserts closed caption data to already encoded H.265 stream and renders. Because mccparse outputs caption data in display order, "caption-meta-order=display" property is required in this example.
