Switching from analog to digital input, stream output, and closed captions

[staze]

Hi All,

My campus until today had an analog cable feed from Comcast. I was encoding this, and streaming it out with:

Code: Select all

v4l2-ctl --set-freq=343.25 --device=/dev/video0 --set-ctrl volume=10 #CNN cvlc -d "v4l2c:///dev/video0:v4l2-input=0:v4l2-standard=NTSC:v4l2-width=720:v4l2-height=480" --sout '#standard{access=http,dst=:8001,mux=ts}' &

It worked, but obviously that doesn't work with digital cable (clear-qam)

So, got my channel scan, but I'm curious about two things.

One, I don't get what the "program" piece is in this command listed here (https://wiki.videolan.org/Documentation ... B_Channel/):

Code: Select all

vlc -vvv --color --ttl 12 --ts-es-id-pid --programs=8508,8505 dvb: \ --dvb-frequency=11739000 --dvb-srate=27500000 --dvb-voltage=13 \ --sout-standard-access=udp --sout-standard-mux=ts --sout \ '#duplicate{dst=std{dst=address1},select="program=8508",dst=std{dst=address2},select="program=8505"}'

Is this basically the stream (as in, video, audio, etc)? are these all the same regardless of stream, or do you have to figure out which ones they are?

I think I can get the stream to work, but I'm curious how I can basically burn the closed captions onto the stream. The streams are shown on digital signs in our building with no audio, so closed captions have been a desire for a while.

Thanks!

captions transport is usually video, so as long as you don't reencode, it should be still there

Cool.

I still can't get streaming to work though. =/ All the dvb stuff I've found doesn't seem to work. This is unicast.
