Virtual Capture Device integration

Hello,
I want to encode and send to a FMS server for streaming over
Internet some live stream. By live I mean it is generated in real
time. Basically, I have created a DirectShow filter that is
registered as a capture device, and I pipe my video to that stream.
DS filter should have on it's output pin uncompressed RGB24. I
decode my live source with mencoder in uncompressed RGB24, and pipe
that to my DS filter, that sends it to it's output pin.
I can see the live source perfectly in AMCap!
The problem is in Adobe FME, If I select my virtual capture
device in Adobe FME, I see only green garbage. The image is heavily
distorted and green. Why does it work in AMCap, but not in Adobe
FME? Should I use a specific format (instead of uncompressed RGB)?
Thanks!

It works now, although the video is a bit choppy. I made a
logging mechanism and frames seem to render in weird timings.
Anyway, the problem is now audio. How to implement audio and how to
sync audio with video. Any tips?
What audio format does Adobe FME expect from filters? I need
to know that to convert to it first. PCM?
This is a sample (frame: rendering time)

Coremediaio support, supporting modern capture devices

Planning to write a coremediaio virtual capture device for OSX. coremediaio is apple's modern replacement for quicktime video digitizer components
Any plans to use QTKit and recognize such devices? It appears that FLME is still using the ancient sequence grabber. Any plans to port flash live media encoder to 64 bit.
best,
Tuviah

Windows media player 11 can play AVCHD very well on windows vista already. And the .MOV native support actually worries me. If that happens, would apple still be making quicktime for windows? will quicktime pro still be on windows? because as far as i know there was no more windows media player on the mac as soon as flip4mac(well, it was made by microsoft..) came out.

Virtual video capture device driver for screencapture available ?

Does anybody know a way to get screen capture in form of a virtual video capture device? I know there are drivers available for other OS (e.g. Windows), but is this possible with OS-X too ?
I want to use the screencapture not only in iChat, but in Flash based videoconferencing/streaming solutions as well, so the normal screen sharing would not work.
thanks for any help, Mark

Problem with video capture device, with a virtual camera

I try to use Adobe Flash Media Live Encoder 3 with a virtual camera(DirectShow Filter) but met such a problem:
"Error connecting input preview RGB filter."
"Failed with error 80004005:SetupInputVideoPreview(pFilter, pguidCategory)"
"Failed with error ffffff97:SetupVideoPreview(pFilterSource)"
"Problem with video capture device. Please verify that the video capture device is working correctly and is not already in use."
However, it is good to use AMCap,
what's the problem with FMLE.
Looking forward to your replies. Thx!

Did you ever figure out the problem/solution?
I am experiencing the same thing with my virtual camera filter when connecting to FME?

Program to pipe screen capture into virtual camera device

I'm looking for a program that could register a virtual camera with the operating system, record my entire desktop, and pipe the output of my desktop into the virtual webcame device. THis would allow me to share my screen with any app that used camera, such as google chat.

I believe that for most apps, you can just copy the .app file from /Applications/ to wherever you want-it may break some updating functionality, but that's the only way to have it in a different location.
Good luck!

Multiple Capture Devices on Windows

I have two USB based capture devices running on my Windows Server 2003 box. I need to transmit the feed from both devices simultaneously. Unfortunately only one entry for the VFW shows up in the list.
When I do my testing and try to transmit from JMStudio things work fine. Windows pops up and asks me to select a capture device. I can handle that. When I try to run two instances of the video transmit class, same deal. I can handle having to select the devices.
However when I use the VideoTransmit embedded in my code as an external class I never get the selection window. I just get an error that says the device is already in use....
Any ideas on what I can do?

So I have solved it. As it would turn out you can only have one connection to vfw in any single virtual machine, so what I had to do was run it in a separate command line window. I find this a serious pain but what can you do.
Hopefully this helps someone and they don't spend two days trying to figure out the problem.

Virtual video device

Hi guys / girls(who knows)
It's a bit off the strict "archlinux" subject, but I have a technical challenge that I'd like to share with other experienced linux users / developers.
Here's the context : I'd like to implement some kind of virtual video device, that I could feed with some data (typically a feed from a "real" camera, post processed and mixed with other information, for video chat use). I'v googled around for existing implementations, and found the following :
* http://www.lavrsen.dk/foswiki/bin/view/ … backDevice
* http://v4l.videotechnology.com/vivi.html
* http://v4l2vd.sourceforge.net/
but unfortunately all of these solutions require kernel-space intervention. I ideally would like to remain exclusively on the user-space side, for ease of redistribution and maintenance. I think there's also a possibility using gstreamer, that has a v4lsink element I think, but gstreamer is not something I'm very familiar with.
Anyone of you having any ideas how I could do that? I will seriously start looking in-depth at the V4L2 API, but any lead to narrow down my researches would be welcome.
Thanks in advance,

5.1.4 update breaks HDV capture? Unable to Initialize Capture Device

Problem:
Final Cut Pro cannot capture standard 1080i60 HDV footage from Sony FX1 camcorder. FCP reports "Unable to Initialize Capture Device" when the log and capture window is opened. However, the footage CAN be captured in iMovie (which is interesting, and unacceptable). When HDV>DV downconvert option on camcorder is activated, footage CAN be captured as anamorphic SD, so the camcorder and FW do work.
The problem is occuring on a rock-solid FCP system that I use on a regular basis (mainly for SD editing). It has been approx 2 weeks since I last attempted a HDV capture, the system has been working great with SD footage (still does).
Factors that have changed to my knowledge since HDV capture was last functioning properly:
*Added a new external FW drive into regular usage (a different brand than normally used, no issues with it so far).
*Updated FCP to 5.1.3, and then 5.1.4 when that fix came out. All SD captures and work have been fine so far.
Here's what's interesting...I had a copy of the FCP v5.0.4 .app that I had saved an archive of prior to the crossgrade update. Guess what? I can load it up, and it captures HDV without any problems! With that in mind, this looks like an FCP 5.1.4 issue. But I am at a loss on how to proceed further in troubleshooting. Many thanks in advance for any assistance.
Matt Jeppsen
FresHDV.com
---NOTES---
What I have tried:
*Attempted capture with a different Sony FX1 camcorder.
*Swapped firewire cables and system firewire ports.
*Attempted capture with camera FW chained to an external HDD.
*Unplugged all other external firewire devices from the system.
*Trashed FCP prefs using FCP Rescue 5, created new project using Easy Setup (for HDV).
*Tried different variations of FCP A/V settings, tried all the HDV FW device control presets and the HDV AIC capture preset.
*Per instructions at http://docs.info.apple.com/article.html?artnum=301852 I removed the numbered Quicktime pckg Receipts and re-installed the latest version (7.13). Post-install/reboot, I repaired Disk Prefs and Verified the disk using Disk Util.
*Have also attempted installing QT 7.13 2 and 3 times in a row, also trying disk prefs repair BEFORE the post-install reboot.
Final Cut Pro Audio/Video Settings:

*VCR HDV/DV: HDV
*COMPONENT: 1080i/480i
*i.LINK CONV: OFF
*TV TYPE: 16:9
*A/V->DV OUT: OFF
System/Software Facts:
*Final Cut Pro 5.1.4
*Quicktime 7.13
*PPC Mac G5 2.7 Dual (2.5GB RAM)
*35GB free on System, 45GB free on internal FCP Scratch disk
Final Cut Pro 5.1.4, G5 DP 2.7 (PPC) Mac OS X (10.4.8)

I think I figured out this vexing problem. I too was having the same issue. Check to see that your Quicktime is newer than 7.1.2. If it isn't you'll have to upgrade it. I only upgraded to 7.1.6 here because I was afraid of going to a really new version. http://www.apple.com/support/downloads/quicktime716formac.html. After I upgraded my quicktime, I ran software update and the Final Cut Pro 5.1.4 update appeared. I hoipe this helps.

Unable to Initialize Capture Device

Hi,
I am having a problem importing/capturing HDV video from my JVC HD GR 1 getting "Unable to Initialize Capture Device".
I have been able to capture fine up to this point, finicky some times to be sure, but workable, then in the last few weeks it began getting more and more finicky (wouldn't connect to camera, restart and it works fine), until just the other day it wont connect no matter what I do!
Help?
Ask questions if you need clarification.
Camera: JVC HD GR 1
Tape: Mini DV
Format: HDV
Software: FCP 5.1.4

Unfortunately when both "Capture" and "Device Control" presets are not set to HDV it wont even try to connect and gives me this warning:
"To capture HDV source material, both the Capture and Device Control presets must be configured for HDV; otherwise, to capture in another format, both must not be configured for HDV."
As a side note when my camera was connecting to FCP. FCP would only give me on screen controls half the time.

Unable to initialize capture device and device control in HDV

I shot with a Sony HVR-Z1U/Z1N and am using a Sony HDV 1080i tape deck to digitize.
I recently purchased a MacBook Pro and installed FCP Pro 5 on it. After getting over some time code issues we were chugging along, when on the 4th tape the image on the log and capture screen suddenly dissapeared (I could get audio and could see the image on the tape deck). Well after taking the tape out, checking and rechecking it I popped it back in and ever since then, I have been getting this error mssg "Unable to initialize capture device and device control."
I have tried deleting the preferences and starting from scratch. If I do that, and choose the easy setup with HDV- 1080i60, it gives me this error "Unable to locate the following external devices- HDV (1440 X 1080) 30fps.
I upgraded to FCP 5.1.2 this morning and upgraded the OS to 10.4.7 and QT to 7.1.3 and still no change.
Im at my wits end, Ive been working on this for a whole week now.
Thank you,
Bugs

It has been reported to take more than one attempt to correct the installation but, if properly executed on a machine without other system problems, the QT reinstall process does work. The key element here is you must reinstall QT after you trash the receipts. The process is listed below.
x
To do a full quicktime reinstall.
Go to /library/receipts and delete any files that say Quicktime followed by a number e.g. Quicktime703.pkg
Go to the Apple quicktime site and download the appropriate version of Quicktime to your hard drive.
Run the Quicktime installer.
Repair Disk Permissions for your System Disk (Disk Utility > Select the system disk > Repair Disk Permissions)
Reboot
If this doesn't work, then the problem lies elsewhere:
1. your system - user preferences, firewire ports or other system elements.
2. your equipment - camera/deck/firewire cables.
3. your process - not setting up the software properly or using the software erroneously.
Listed below is a troubleshooting process. Not all steps are appropriate but the general process of isolating the problem is useful.

Detecting Video Capture Devices without Installing JMF

Hi All,
I want to detect the video capture devices, without installing the JMF.
I had included the jmf (windows version) in lib path in netbeans ide. I am able to detect the audio capture device. But unable to detect the video capture devices. But if I install the JMF, I am able to detect the Video Capture devices in My system. Can anyone help me?
Thanks,
Vinoth Kumar.

YES! Please take a look at SIP Communicator project. They have all what u want.
The main idea is copy all .dll files to System or System32 (Please check files which JMF will copy to ur computer and where).
U need to have jmf.jar and sound.jar too ( maybe more) in your computer.
Your program should have DirectSoundAuto.java, JavaSoundAuto.java, JavaSoundDetector.java, JMFInit.java. Those files are in JMStudio source code. They are used to detect all capture devices and register it to JMF, but wait !!! where they will be saved? In order to save information about capture devices which are detected, you should create "jmf.properties" file in the same location with jmf.jar.Therefore, u should modify the JMFInit.java so it can check if the "jmf.properties" exists. If it's not, you have to create it.
Check SIP Communicator at Folder "media" then "device". They have modified those files I mentioned above and created some new files to SC can detect more devices.

Video capture device bad image/no sound

Hi !!
I bought this "grabby" usb dongle from terratec to record old vhs cassete on my computer, but is doesn't work on linux. (It works ok on win7, so cable-connections problems are excluded)
On vlc I did 'open capture device', choose /dev/video0 for vid, hw:2,0 for sound(tried them all anyway), and PAL/SECAM video standard.
Problem is I have a super crappy video image (on mplayer also), and no sound. The video is colored, I recogize it, but the pixels are huge, it's awfull.
After some research I found that a module named em28xx is supposed to handle this device. I found some forum post here and there about the sound problem, it is addressed with a 3years old patch on em28xx-cards.c (which doesn't exist on my machine, so I couldn't apply it).

Hi again !
Thanks for you tip nomorewindows. The programs tvtime and xawtv worked out of the box concerning video !! xawtv, however, crashes everytime I try to resize the (very) small window. As for tvtime, there is no sound (output is it can't open /dev/mixer so I guess it's fixable, I'll look into it).
I started reading the doc but I didn't found yet if it was possible to record the output with these program...
Concerning the cables, you are right they are not special at all it is standard : there is the triple (yellow=composite video, red/white for audio) cable and a fourth one for video but with inferior quality, I didn't connect it (it's either the yellow or this one for video)

How to connect a video capture device to Satellite M30X 127

I'm going around in circles trying to find a video capture device that will function with a laptop and would be grateful for advice. By way of example, I'm now looking at the 'Canopus ADVC-110', although still looking around (but not Pinnacle, who seem to have a terrible reputation for capture items).
Problems include:
1. Main problem is - many video capture external devices require a 'line-in' to PC for good quality audio transfer. This laptop doesn't have a line in, only the mike and headphone jacks. In addition, I've also tried a few RCA pins in the 3.5mm microphone/headphones jack and they were too small. How to solve the problem of getting audio from vcr to my PC?
2. The ADVC-110 connects to the PC via Firewire (and S-video), but is a SIX-pin type. M30X is a FOUR-pin type. Are there adapters available?
3. Some capture programmes seem to require huge capacity of RAM. Is a laptop going to be suitable to do the job? (I simply want to capture old vhs tapes from vcr to PC, then burn to DVD with Nero 7 or similar).
Thanks in advance!

Hello
You are right! You must use external device for signal transfer to your notebook. I dont know where you have this info but I have good experiences with Pinnacle product. For data transfer I have used USB port.
'Canopus ADVC-110 is not known to me but I dont see any reason why this should not work well. Use delivered software for video capturing and there should not be any problem.
Only thing is that after recording the whole video material must be prepared for burning and unit need a lot of power to do this well und fast. When you buy this and want to use on right way I recommend you to expand RAM to 1GB.
Compatible memory modules for your Satellite M30x are:
PC2700 512MB (PA3312U-1M51)
PC2700 1024MB (PA3313U-1M1G)
Bye

Advice Needed for Video Capture Device

Hi,
I'm looking to buy a USB (or Firewire if they exist) video capture device that can take S-Video and composite connections. Could someone recommend me best one under $150 that is compatible with Snow Leopard? Also, and more importantly, does anyone know if it is possible to capture the signal via Quicktime Pro or Final Cut Pro rather than bundled third party software.
Thanks!

I used the predecessor to the Canopus ADVC55 to load VHS tapes into a mac. As I recall I brought the firewire signal into iMovie (could have been Final Cut Pro too, as I had both on the system). Here are the specs: http://www.grassvalley.com/products/advc55 . Also some comments on it at http://www.amazon.com/Hardware-ADVC-55-d-Converter-Ntsc/dp/B000HGVZG0/ref=sr_1_2 ?ie=UTF8&qid=1323954590&sr=8-2 Here's another source to buy it: http://www.bhphotovideo.com/c/product/312315-REG/Grass_Valley_602005_ADVC_55_Ana log_to_Digital.html .
They also make an ADVCmini, which I haven't used, which is probably less expensive, with specs at http://www.grassvalley.com/products/advcmini

Adobe premiere elements 12 with diamond vc500 one touch video capture device.

Adobe premiere elements 12 and using Diamond vc500 one touch video capture device.
AVI files will not load into Adobe premiere elements 12.
I bought what I thought were the two best software and capture devices.
I am archiving old VHS tapes and using Diamond vc500 capture software called EZ grabber. I thought the best archiving format would be AVI files. As I just started this project. I am willing to do what is needed.
That even being, going and buy another capture device that being for a VCR to PC using a USB are even a Video card.
EZ grabber software ask you to record in what format. I picked AVI. There is DVD - SVCD - VCD - MPG4. I want to archive then go back and edit. The DVD or SVCD format, is that not the same as mpeg 2?
You and I know the drill. Saving in what long term archive format and that dare thing about video compression and losing quality of the videos. Its all a nightmare.
Once again I am willing to buy another capture device for a VCR that will work with Adobe premiere elements 12.
Help please with long term archiving format and capture device.
Thanks

The answer is B.
Capturing the VHS content to computer (via the Diamond vc500 and USB connection and EZ grabber) to obtain an .avi file on your computer and then trying to import that into Premiere Elements with its Add Media/Files and Folders?
When I do that, the Adobe premiere elements 12 crashes or only loads a 2 mins of video.
The firewire connection device "Canopus" product sounds great. But I really don't want to spend that much on my home videos. My PC does not have a Firewire connection. So add a new card for that and the Canopus product. I could just pay someone to do my VHS tapes.
Diamond vc500 $35
Adobe premiere elements 12 $65
Firewire card $50 plus
Canopus $180
$330 is way too much for simple home VHS videos
