View 3 Replies View RelatedI'm building a Linux system specifically for video capture in prep for yet another video games review site I want to attempt. She is running Debian Sid with Enlightenment as her desktop.This system actually has two different devices that should be able to do the capture from the Wii, PS2, XBox, and other systems that can connect to it. The first is the video card itself, an ATI Rage 128 Pro AGP 4X, which has TV (aka composite) in as well as what I am guessing is S-Video in (not positive on that since the port has significantly more than 4 pins unlike the S-Video ports on my AV switch). The other is an external ATI TV Wonder USB TVWonder, which has coax, composite, and S-Video inputs.
When I installed and ran XAWTV, it crashed with a complaint that there was no video grabber device found. When I did lsusb, I saw that there was no sign of the external USB capture device. lspci showed the video card, but no mention was made of its TV capture feature. However, I am not certain if there was supposed to be any separate entries for that.So anyway, before I start bogging you all down with what may or may not be too much system data, I first need to know, is this an exercise in futility with the hardware I have? Is video capture with Linux even possible with these, or should I start shopping for something else?
Are there any USB video capture devices that work with Linux? Something that will take an input from RCA video and audio jacks.

View 5 Replies View RelatedI have a digital camcorder, an analog camcorder, and a set top dvr.
I want to get video and audio material from them onto my notebook (i.e. I don't have any PCI slots, etc. to plug a video capture card into).
My notebook runs kubuntu karmic Linux with Windows XP (in a VM).
It has USB 2.0, firewire, PCI card, and Express Card interfaces.
I am looking for any reasonable way to do this.
All three devices have composite video out and left and right audio out RCA jacks. The digital camcorder also has USB and firewire ports, but didn't come with any software (and AFAIK the software has long since become unavailable).
Plugging the digital camcorder into my notebook via USB or firewire cables didn't do much of anything in either Windows or Linux.
Awhile ago, I bought the Hauppauge USB-Live 2 video capture device (it's a smart cable that's supposed to convert from the RCA plugs to USB), but had no luck getting it to work in my XP vm and very limited results under Linux - with a lot of help from a fellow lug member.
Under Linux, I tried using polaris.
[url]
At this point, I just want to get the job done any way I can, but since the devices are still in use, it's not a one-shot deal, so I need a solution that will continue to work. I'd prefer it in Linux (where it would also have access to more computing power), but XP would be fine too. If I need a different interface/converter, I will buy one if it's not too expensive.
Soon, I will also have access to my partner's new notebook, but haven't reconfigured it yet. When I do, it will be running kubuntu lucid with Windows 7 in a VM.
I am getting myself set up to create a series of Linux based how to videos, with the first being on building a Debian box for general web use and document creation, etc. on "recycled" hardware, starting at the very beginning, even going so far as to include how to download a netinstall iso and make it into a burnable CD.
So anyway, one very important ability I need for this project decent video capture capability. I need to be able to capture the output of the install into a proper video format, on which I can provide commentary about what is going on on the screen.
I have another Debian box that is equipped with a bt878 TV/Video capture card, and the box I am using for the Enlightenment project I posted about many times recently has a Geforce 5600FX. Last night, I ran a cable from the S-Video out on the GeForce to the composite in on the capture card (had to go composite since I don't have an S-Video cable long enough to cross the room... Cable used has an adapter to switch to a standard RCA cable.
So, after getting the two hooked up, I got XAWTV installed on the capture box, and rebooted the other computer. With XAWTV running, I was able to see the boot up process going through the capture card. So I think I am on the right track.
But (and isn't there always a big but?), the captured video leaves a lot to be desired. Here is what the final AVI file looks like: Warning. This is a big file
As you can see, the video quality is mighty poor. And it wasn't just the final video either. It looked this bad in XAWTV as well. So, is there any way to improve the video quality in XAWTV; and also, how about increasing the app's resolution since the tiny square of video is not easily readable, and I will need it to be legible on a full size display?
If XAWTV is unable to do this, then can anyone here recommend and alternate video capture app that would be up to the task at hand? Also would like an app that will actually save my settings, as XAWTV always reverts to whatever the default settings were when I shut it down and restart it.
In addition to improving the quality of the S-Video output, I also need some recommendations on how to reduce the filesize when capturing the video. The original, before Photobucket converted it to flv was an avi file over 10MB, which is really inefficient for my needs.
Finally, can anyone recommend a PCI video card that has S-Video output (must be a 4 pin S-Video connector), and has at least 8MB of video RAM? Or does some kind soul here have one lying about that they may be willing to part with inexpensively?
So, a summary of this post...
1: How do I get XAWTV to provide S-Video capture that is actually readable?
2: How do I get XAWTV to record in a higher resolution?
3: How do I get XAWTV to save my ******** settings?
4: If any of the above 3 are not possible, what are some other alternate video capture apps to try?
5: Hook me up with a 8MB or higher PCI video card that also does S-Video out? (4 pin S-Video connector is a must).

I'm not sure if the following is an openSUSE specific issue,a motherboard issue, a 64 bit issue, or if it's something else entirely.I have a Hauppauge WinTV (BT878) card that I would like to use. I have used this cad before in an older computer, with linux, and it worked fine then, so I'm assuming it still works fine now.
The main issue that I have is that I can't change the resolution to (motv, transcode, etc) to anything over 352x240. If I do, I get errors about not being able to dequeue frames and such and I get no picture and/or the program hangs/crashes. Also, I can't get lavrec to work no matter what resolution I set. It crashes with queuing errors as well.In case it matters, my motherboard is an Asus M4A78T-E, I have openSUSE 11.2 64 bit.
I'm trying to record my desktop and tested some solutions. While I was impressed how small .mng files could be, it is a disadvantage that I can't capture audio with it and many users won't be able to open these (browser / Windows). I have been very impressed by the xvidcap instruction videos: 4:30 in only 9MB, which makes 180MB for 90 minutes. This would be suitable. With Camtasia my professor even records 90min in 100MB. The problem is that xvidcap hasn't been updated since 2006 and seems to be dead. RecordMyDesktop needs 6MB for 1 minute or 540MB for 90 minutes, which is too much. Could anybody give me some hints on how to capture very small video files, which are still clear enough to read text in a format most users can open? It would also be cool to be able to show specific PDF or HTML pages synchronised to the video.

View 3 Replies View RelatedAnybody had any success in getting ffmpeg to work as advertised with video capture from a webcam? I really want to convert the webcam output to VP8 or H264, but apparently ffmpeg can't even capture the webcam with a video4linux device.
Code:
I wanted to share this nifty technique I came across for capturing video using the command line. The problem: I have a bunch of old VHS tapes (remember those...?) and need to get them digitized. I have a VCR, and a Dazzle Hollywood DV Bridge which captures video to DV over Firewire (IEEE1394). I first tried using Final Cut Pro, but it wouldn't capture, perhaps because it expects a controllable DV camera, and the Dazzle isn't a DVC device. I then tried my other favorite video editing app, Kdenlive, but it seemed to have the same problem.
I took a quick stab at the other common editors in the repositories (Kino, Openshot, etc.), but no luck with any of them. Then I remembered the dvgrab command, and gave that a shot and it worked, giving me a nice .dv file. However, DV makes pretty big files, which I wanted to compress down to something more manageable. Since I was going to be digitizing hours and hours of tapes, it would be great if I could compress while capturing. A little more googling and I had the answer - you can pipe dvgrab directly into ffmpeg! Here's the command:
Code:
dvgrab -format dv1 - | ffmpeg -f dv -i - -b 2000k -ab 512k -y output.mov
the first part starts the capture, in DV1 format, and outputs it to a pipe file. usually you give dvgrab a filename, like
Code:
dvgrab -format dv1 capture.dv
the second part does the encoding:
-f dv: use DV format
-i -: input from the pipe
-b 2000k: video encoding bitrate of 2000k/sec, high quality
-ab 512k: audio encoding bitrate
-y: overwrite file if it exists
I didn't set the codec explicitly, for Quicktime it defaults to MPEG4. This worked great, capturing a 2-hour tape into a high-quality quicktime around 2GB. But I also wanted to be able to view the capture while it was going. Since I left the field monitors and audio splitters at the office, I had to figure out how to do this in software. Turns out that the "tee" command does exactly what I needed - the shell never ceases to amaze! Here's the full command:
Code:
dvgrab -format dv1 - | tee >(ffmpeg -f dv -i - -b 2000k -ab 512k output.mov) >(playdv --disable-audio --no-mmap)
tee uses the
Code:
>(command)
syntax to pipe simultaneously to multiple processes. The only thing that didn't work was audio playback, which was choppy and introduced errors in the capture file. I think a little tweaking with the capture rates could fix that.
