Recording DTT with VLC

[morice]

Hello,

Please forgive my poor english.

When I watch a digital terrestrial television program with a tuner card and VLC, if I click on the red record button, it saves another channel.

If I try right click/record directly in the Playlist, i don't see the current TV program no more and i get the VLC orange icon, it creates a line "Distribution" in the list and it also records another channel.
In addition to which I do not see how to stop recording because I can not find anything about it in the context menu ... and if I click on the red button to stop the recording, a second recording starts...

Windows 8 desktop mode.

Thanks for help.

What is DTT?

Deselect in Advanced Preferences - Input / Codecs the option Prefer native stream recording.

You might need to select the correct program in the navigation menu, as VLC may save the whole transponder.

Thanks for your answers.

DTT: Digital Terrestrial Television.

I tryed to deselect Prefer native stream recording but it doesn't fix.

It saves only one program, but you may be right: if i try to save a channel VLC seems to randomly pick one of the channels in the same multiplex.
But i still don't see how to select the one i want.

Am I right to think that "transponder" is a synonym for "multiplex" ? ► http://en.wikipedia.org/wiki/Multiplex_%28television%29

In a packet frequency (transponder) multiple transmitters are included (mostly 4).

A transmitter is identified by the frequency and the service ID.

When in Advanced Preferences - Input / Codecs the option Prefer native stream recording is enabled, the transmitter will be recorded with the lowest service ID.

When in Advanced Preferences - Input / Codecs the option Prefer native stream recording is not enabled, the transmitter is recorded, which is also reproduced.

I think DVB-T (Digital Video Broadcasting – Terrestrial) is Digital Terrestrial Television.

Ok, in Wikipedia i found others definitions for transponder and transmitter. I was lost and couldn't understand.

To understand what you said, i replaced the word transponder by multiplex and transmitter by channel. Then everything became clear.

Anyway it works now i can record the channel i want since i unticked Prefer native stream recording (i don't know why it didn't work when i first tried, maybe i hadn't restarted VLC)...

Thanks for this tip !

Of course, DVB-T is the European standard for the DTT (Digital Terrestrial Television).
Many others DTT standards exist: DVB-T2, DVB-H, ATSC, ISDB-T...

Yes, this was it. The VLC needs to be restarted after the setting change.

And now... how to keep recording when i zap ? For now, it stops the recording.

I would like to chose a channel, start recording it then keep the recording process on, even when i zap to another program

You can't do that with the UI. You'd have to use the CLI, and then it's questionable whether it can even be called zapping anymore.

Why do not you use for zapping a new instance of VLC?

Do you know the CLI procedure?

Tried but the card doesn't look to provide more than one flux. This make me realize i can't zap if i'm recording, should i get a card that provide two channels at the same time?

Please refer to the stream output documentation or the wiki.

What you mean with "card" and "flux"?

[morice]

What you mean with "card" and "flux"?

"Flux" may be wrong: i should have said "channel" or "program".
I said it in the same sentence: "Tried but the card doesn't look to provide more than one flux. This make me realize i can't zap if i'm recording, should i get a card that provide two channels at the same time?".

"Card" is for tuner card.
I said it in my first post: "I watch a digital terrestrial television program with a tuner card and VLC..."

No, I mean not a second card. You should start a second instance of VLC.
You can not simultaneously access different transmitters.
But you can access to different channels, which are transmitted from the same transmitter.
If you want to simultaneously access the stations of different transmitters, you need two tuner cards.

Tried but a second instance doesn't work in that case, even if i try another channel within the same multiplex. Thats why i think my card can't afford more than one channel at the same time, but i could be wrong.
