Analog Video Capture in LINUX

[xiiDenTiiTy]

Linux = Ok...

Windows = Hmmm.. how to put this.... Sexyness!!!

[vaasnaad]

@xiiDenTiiTy I'm at work on a Saturday because a Term server spontaneously stopped working mid-stream and I had to call Calcutta to even start to try and get it working (and I'm MS Certified). I go home to my Linux setup every night, never worry about viruses, malware, maintenance, etc. and have all the Windows apps and games I want running via Wine. Wanna know which one is more sexy in my book? hehe

[xiiDenTiiTy]

@vaasnaad lol

[andymaddie7919]

Tap Dat.

[brinausser]

you can also use command:

cat /dev/video0 > test.mpg

Where 'video0' is my analog input (yours may be different) and 'test.mpg' is the name of my file. Of course call this output file whatever you choose.

This command is run in a normal terminal and exited with the 'Ctrl+C' key combination. Hope this helps someone!

You are a fuckin sad cunt are you are A SPA

[vaasnaad]

@WeePaul2010 Say what?

[TuxNoBux]

@WeePaul2010 & your fucking low life muppet give the man a break you fucking prick!!!

[trilbies]

Hello tehre Vaasnaad, thanks for this! exact;y what I was looking for!

[vaasnaad]

@trilbies Thank you!

[tykerdog33]

Dude get to the point. 

[vaasnaad]

@tykerdog33 There is no point. Life is a journey.

[iamonlinew]

Does anyone know what the song at the beginning is called?

[vaasnaad]

@iamonlinew Block Rockin' Beats by I believe the Chemical Brothers

[iamonlinew]

@vaasnaad Thanks!

[OniLink10]

I have a question, since I'm new to this. Is there any way to modify the script to get audio input from both the Dazzle and a Microphone plugged into the Computer?

[vaasnaad]

@OniLink10 Well, this script lets you specify the audio input with your mixer, so you could use one or the other at a time, but if you're talking about copying both audio tracks, that's a little more advanced in the scripting department than I'm used to. You can do a second pass and add additional audio after the fact if it's like a narration track. Jack will let you do a near infinite amount of audio mixing.

[kaddy01980]

LOL @ you using Freespire LMAO :)

[vaasnaad]

Well... I was new and it offered the additional packages as the base install. Much like Mint today. But I couldn't update because they kept changing distros! Which was so frustrating it did seem kinda silly. I got a nice apt-get script that gets me all the bells and whistles but I've done the upgrade on the past 2 versions of Ubuntu and I'm still flying. hehe

[capoman1]

Dude we all know that is NOT your real hair!

jk

I have been through ten programs for capturing from my bt878 card. I am still working on it!!!

[SleeplessDad]

Thanks for taking time out to do this

[vaasnaad]

I'm glad you appreciate it! Any old excuse to play with video production makes me happy! :-)

[imthepod]

wa program u usin to record?? n howd u get the audio good?

[vaasnaad]

I used plain 'ol mencoder to record all this, using the script in the comments. The audio... well that's just the mic on my webcam, it's pretty good. But I leveled out the audio and did all the editing in Cinelerra.

[imthepod]

can u do a video on how u edited it on cinelerra

[vaasnaad]

Yep, that's coming up in the near future! Like two more videos... now that things have settled down and I can actually make them again!

[ucyih8]

my video post shows how i was able to get anolog through dazzle and vlc. i cannot seem to get audio yet. i am about to try out some of the stuff you mentioned.

anyhow,great videos. some corniness but i learned some stuff too

[vaasnaad]

Man, I tinkered with VLC FOREVER because I was determined to use a GUI with capture! Can't wait to see how you did it.

[vaasnaad]

I guess it was just Freespire, because I'm actually able to access my capture device on Kubuntu!

[RyanChristianson]

to be honest i have abosolutely NO CLUE what this video is about and i dont understand anything in it but somehow i feel like watching your videos make me feel smarter so i subscribed

[vaasnaad]

I'll take that as a compliment. :-) THANKS!

[Iantotheus]

Ubuntu 8.10 Intrepid Ibex. Camera is a Vista IM Live! It works pretty ok with cheese, but there is major audio delay. :/

[vaasnaad]

Linuxjournalonline (check their channel) has info on a kernel patch that will get you ultra low latency audio that might help. Are you getting the delay when you do analog capture this way? If so, let me know and I have a tweak you can use to reencode and nudge the audio. Haven't tried it live, but in theory it should work there too.

[Iantotheus]

Argh mencoder isn't working for me because I have a [ 2796.093202] gspca: probing 041e:4052

[ 2796.304134] ov519: I2C synced in 1 attempt(s)

device, which is v4l2 as far as I know and mencoder does not work.

[vaasnaad]

What's your distribution and release, and what type of camera are you using? There's a known kernel bug with gspca in some configurations.

[Acu969]

You are the funniest and most interesting tech presenting guy I have seen. You seem so positive, genuine, fun and unpredicted, yet concrete and to the point. This is so unique. Just a notch of better Audio (pros say that audio is more important than video if you would need to decide which is which - a lavalier mic - maybe wireless if you present far from the camera as in other videos), and a bit of usage rule of composition in video - will make you the best around.

THANK YOU !

[vaasnaad]

WOW! Thanks so very much for this comment! I'm actually working on sound... doing noise gates, compression and EQ in lieu of a clip-on mic, but I was in audio for 10 years and you just can't beat the right mic. I'm just having fun, but trying to help out and get back in to video after a LONG hiatus... hope to get the upcomings more entertaining; I'm just cramming so much info in lately!

[AlbertaCanada420]

iam a windows xp user and iam trying to get ubuntu to show up on xp as a window but its not working ill start looking like you in your video going insane can you help and by the way the editing is pritty funny nice job!

[vaasnaad]

Are you trying to run Ubuntu as a virtual machine in Windows from CD, or are you trying from a second boot on the HD? Glad you liked it - I've been meaning to put more funny stuff in lately. :-)

[samphilomath]

To see the video input on your screen, just try this.

mplayer tv:// -tv driver=v4l:device=/dev/video1 -vo x11

Awesome video.

Can you please send me the link for the video showing how to record your desktop screen with mplayer/mencoder

[vaasnaad]

That worked! I modified it to work with my capture card and let it scale with this:

mplayer tv:// -tv driver=v4l:norm=ntsc:input=1 height=640 width=480 -vo x11

Didn't look pretty though. I think if you're wanting a no-fuss preview TV Time is really the way to go for that GUI ease.

This video I actually just did screen captures and inserted different jpgs in Cinelerra. Haven't worked out mencoder but RecordMyDesktop is a great app. I'll cover that in an upcoming segment. Glad you liked it!

[GegoXaren]

kino?

theora? xvid? avc?

vorbis? faac? flac?

[vaasnaad]

Not sure I understand the question or even if it was directed at me but..

I've found that using mencoder, divx/mp3lame gives me the most reliable video/audio sync. And I gear it to Cinelerra, which supports OGG but I haven't tried it since I usually package my MOV from Cinelerra with mp3 audio so it goes up on YouTube without extra steps. Kino only supports DV capture, not analog, but I just upgraded my camera, so I'm going to be using that very soon!

[vaasnaad]

And I'm by no means an expert - still learning, but this is what works best for ME after a looooong, hard and frustrating time.  So hopefully it will work for some others having the same problems too!

[Jacc0s]

I'm talking about working ones without problems

[vaasnaad]

I'm having REALLY good luck with K3b - works as well as anything I used in Windows. In fact, it's worked a couple times when Windows wouldn't. AUDIO at this point, haven't had a chance to try the DVD side. Maybe that'll be a topic for a new video if I start another hunt for DVD ripping.

[Jacc0s]

Lol it's really hard to find recording/rip programs it sucks!

[theoutsiderisme]

omfg a real computer nerdd nooooo -runs back to xbox360-

[vaasnaad]

Why, thank you! I try. :-)

BTW you're automatically in the club if you have a hot anime babe video. MUAHAHAHAHA!

[theoutsiderisme]

YES!! indeed MWUAHAHA lol :D

d/w man im a nerd also :)
