Video capture frustrations

Post by LodeHacker » Wed Jun 24, 2009 11:15 am

Yah, good ol' Linux getting on my nerves for the first time since 2006 (no, not going to tell you *that* story) :D

I have a nice and shiny new TV card, it has support on Linux out of the box, I can use tvtime to watch TV, but that's just about it. For the last two days I've been busy to make a proper mencoder command for recording TV / analog video with very fine tuned parameters. All fine and good, but how on Earth am I supposed to preview what's recorded?

I get no visual output, mencoder does its thing and once hitting Ctrl-C all is done. Well, all except the fact that I don't even know what was recorded :evil:

There is one possibility, which is to run mencoder and then after 10 seconds or so, run mplayer to watch the video generated by mencoder. The problem with this setup is the fact that I get to see what's going on 10 seconds later, and it also makes managing the recording process harder. On top of this it just adds to the complexity of a simple procedure, with no real satisfactory result.

Rather than reading the video device in full duplex mode, why can't one application open it in "recording" mode and the other in "playback" mode? I know that the same is possible with audio devices, so why make video capture so utterly complex?!

I basically use my computer display as a TV, so usually I just watch TV, but I would really love to be able to simply push a button and have the application record what I see. It is frustrating because I think computers of this century should be able to do this kind of thing. Oh wait, it *is* possible. I've done it on Windows with Pinnacle software, so what's f**king wrong with Linux?!?!?!?!!?!

Someone help me out :?

I don't want to capture my desktop, what if I decide to browse the Web quickly to look up a word or sentence mentioned in TV? I do that often and it would interfere with the recording process.

Is an unnecessary contribution to this thread.

Virtually no one uses Linux there, no help from them :(

Mplayer does offer the ability to read a streaming output (TV Card) and once configured can record that input using memcoder for the output, which is what it sounds like you want.

Alternative is to look into the Myth-TV project and see how they're doing the DVR setup, which I suspect is exactly what you're looking for.
