Hi,
Can someone give me an example pipeline for processing captions from
decklinkvideosrc into a h.264 or mpeg2 video? Preferably, I would like to
end up with a transport stream.
gst-launch-1.0 version 1.15.2
GStreamer 1.15.2 (GIT)
Unknown package origin
I am starting with a pipeline like:
gst-launch-1.0 decklinkvideosrc device-number=${DEVICE} mode=12
skip-first-time=500 output-cc=true video-format=2 duplex-mode=0 !
ccextractor ! autovideoconvert ! queue ! x264enc interlaced=true !
'video/x-h264, profile=(string)main' ! h264parse ! queue ! mpegtsmux
name=mux ! queue ! filesink location=video.ts decklinkaudiosrc
device-number=${DEVICE} channels=2 name=audio ! audioconvert ! avenc_ac3
bitrate=480000 ! ac3parse ! mux.
Am I putting the ccextractor in the wrong place, or is there other elements
necessary to create the GstVideoCaptionMeta for x264enc?
TIA
John
