View Full Version : [ubuntu] Recording TV on my Ubuntu

May 23rd, 2008, 07:34 PM
Hi I have a TV card on my Ubuntu so I can watch TV when I use "TVtime televisions viewer" and that works fine,

But I like to recording and save it as high quality as possible,

I have read that VLC can do it but I have no idea how I can pick right channel.

I have also read Mencoder can do it but only things I have found dont work so good.

I have even try with some program from my "Add/Remove Applications" but that is not so many that can recording and they I have found wont work at all for me :confused:

I don't want to use Myth TV because I just want to recording, nothing more.


I have found this code on Mencoder homepage

mencoder -tv driver=v4l:width=768:height=576 -oac mp3lame -lameopts cbr:br=64\
-ovc lavc -lavcopts vcodec=mpeg4:vbitrate=900 \
-vf crop=720:544:24:16,pp=lb -o output.avi tv://

The only funny things is that I have to open "TVtime televisions viewer" to pick what channel I want to recording :)

So i have to first open the program, then pick a channel, then close the program and run the code.

have a little problem with the sound

I have to put a cable from my PC card to Line in in my sound card but I can't still change the volume, I think it go 100% and that dont sound good at all when I play what I have recording.

I have try to change the volume for Line-in but nothing happend, no change at all. :confused:


I use

vol=0.2 in my code like this

mencoder -tv driver=v4l:width=720:height=576 -oac mp3lame -lameopts cbr:br=192:cbr:vol=0.2 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=5000 -o output.avi tv://

/Update 2
Is no change at all :(

I have now try with mencoder and transcoder and I have change the volume in the code but same problem

Crackle sound when I try to recording the TV program.
When I watch a TV program it sound perfect but not when I trying to recording.

I have even try to turn off every level of the volume control but I have notice that the code dont care about the volume control at all.

I use Intel ICH5(alsa) and I run on a 2,4Ghz P4 with 1 GB memory so I can't possibly think my computer is to slow.

I maybe have to install windows to see if I can recording without get that crackle sound :(

Use CTRL + C to stop, and play

Install xawtv from Synaptic and use it to scan for channels.

This is how I used it for VLC:
