Hi,

I use VLC 3.0.8 in Windows 10 OS.
I capture signal from DVB-T card and stream it to VLC display, HTTP and a file.
I use VLC UI for the setup, not command line, with following parameters:

MRL:

Code: Select all

dvb-t://frequency=177500000:bandwidth=0

Edit Options:

Code: Select all

:dvb-adapter=0 :live-caching=300 :programs=1317

VLC documentation says about programs parameter that it is "used to specify one or serveral programs to select; VLC selects all known elementary streams of these programs; this is the currently recommended way". I expect teletext to be streamed if the source program has it.
Program 1317 has 4 elementary streams: video, audio, private and teletext. Closed captions are on page 801.

Generated stream output string:

Code: Select all

:sout=#duplicate{dst=display,dst=http{mux=ts,dst=:8080/test},dst=file{dst=c:\\vlc\\file.ts}}

I do not transcode the streams. I duplicate them to 3 locations with the following result:

Display plays the video and shows closed captions.
File has audio and video streams, teletext stream is not there.
Another VLC instance captures and plays HTTP stream. Teletext menu does not appear on VLC UI.

Can you please advise what should be changes in parameters in order to deliver closed captions not only to VLC display but also to the destination file and HTTP stream?

Thanks!

I found the missing parameter. It is --no-ts-split-es .
