# Build gst-plugin-rsclosedcaption from gst-plugins-rs. The closed-caption
# and ST 2038 elements (cctost2038anc, st2038anctocc, tttocea608, cea608tott)
# come from this plugin and aren't packaged on Ubuntu 24.04.
#
# Tag 0.14.5 is the latest release in the gst-plugins-rs 0.14 series.
# 0.14 is the first release with cctost2038anc / st2038anctocc /
# st2038ancdemux / st2038ancmux (added in 0.14.0) and targets gstreamer-rs
# 0.24, matching gst-mxl-rs and the system GStreamer 1.24 ABI from apt.
# 0.13.x doesn't ship the ST 2038 elements; main / 0.15.x targets
# gstreamer-rs 0.26.
