Hi All,
I’m trying to render a closed captions which does contain Unicode two-byte symbols, encoded using the P16 DTVCC mode.
The pipeline example is:
gst-launch-1.0 filesrc location=test_arabian.mxf ! mxfdemux name=d ^
cccombiner name=c ! cea708overlay cea608-channel=0 service=1 ! autovideosink ^
d.track_512 ! queue ! decodebin ! videoconvert ! c.sink ^
d.track_11 ! queue ! st2038ancdemux name=demux ^
demux. ! st2038anctocc name=anc ^
anc.src_cea708 ! c.caption
I see that only ASCII symbols printed correct, all other just are absent. Platform is Windows, gstreamer 1.28.
Is there any trick to get such symbols visible?
If not is there at least a way to dump all text from a selected CEA-708 service to a text file instead rendering into a frame?
