Unable to capture video from webcam in JMF

hi
I am unable to capture video from webcam in an Xlet. I am using Xletview to run Xlet. The method CaptureDeviceManager.getDeviceList(vidformat) returns empty array. Which videoformat should I use and why do I get empty array?

MHP and OCAP only use JMF 1.0, which does not include support for capturing video. You will not be able to do this in any current MHP/OCAP imlementation that I know of.

Unable to capture video from VHS through DAC-200

(Running Final Cut Pro 5.1.4)
I have a DAC-200 to hook up my VCR to my G5 in order to capture video from VHS tapes into Final Cut. I had this set-up working a few months ago, but it was disconnected to rearrange equipment and now I can't get it working again. I have followed the advice from the DAC-200 installation instructions and advice from other forum topics but can't seem to get it to work. I finally was able to get something in the log and capture window besides "preview disabled" and "cannot capture because there is no video." I now can get Final Cut to capture video, however it only captures a blank black screen (and this is all I can see in the preview window).
I've triple-checked every cable hook-up, the G5 recognizes the converter box, the video tape plays fine to a tv. I've even had our IT-guy here at work come check out my set-up for help and he can't figure out what is wrong either. (He did get my log&capture window to get white fuzz in the black screen at one point though. Does that mean anything?)
Any help is greatly appreciated! (I'm happy to answer any other questions too.) Thanks!

I had difficullty with the X.4.10 plus QT7.2 and put my info on the Forum as well as sending feedback to Apple. Shortly afterwards, Apple brought out a short security update which I downloaded and, hey presto, I was then able to use QT7.2 with OSX.4.10. It may be that you missed out on the later small update to QT7.2..... ? Another factor I found was that some little while later I again had a problem so I again installed QT7.2 and over-installed FCP5.1.4 which has resolved my problems for the time being. Worth a try if you still can't get through on the DAC.

Unable to capture video from Sony HD HDR-HC7

I am trying to import video from a Sony HD HDR-HC7 into Final Cut Pro 5.1.1 using the log an capture feature. I have tried most combinations of the presets, but the device is never seen.
iMove (both iLife8 and the earlier version) has no problem at all seeing the camera. However, I do have to set the camera to HDVout rather than DVout for iMovie to see it.
Thanks.

Unable to capture video from my Sharp VL-NZ155 camera

I noticed that is a pretty common statement around,
even so I couldn't find an answer to my dilemma.
I have the new Mac 24" (not that new anymore) with
Firewire 800 cable, and I have Premiere Pro CS4 installed.
I can control my Sharp VL-NZ155 from the capture
window, but I can't capture anything, download it to
the computer.
Any helpful tips?

This is it man... I've googled it and you're right,
it only turns up batteries, but... actually this is the
camera's model: VL-NZ155... It's a mini DV camera
that I bought back in 2003... There's a sticker on it
saying that it's a 10th anniversary Sharp model.

Unable to capture video from Sony Handycam

I am running Premiere CS6 on Win7 Ultimate 64bit. My Handycam is connected via Firewire PCI board. Premiere recognizes the camera, and I am able to use the capture window to move the tape FW and rewind, but when I attempt to play the tape, Premiere bombs and goes to the desktop. I had selected standard capture NTSC since the Handycam isn't HD. I am able to capture the same video without any problems in Vegas and Pinnacle. Is it the settings? Any help would be appreciated!

I had the earlier PC100 for many years and did occasionally have problems with capture whenever I upgraded my PC (I have built my own for the last 20 years). Premiere has had issues with certain chipsets on PCI boards for a few years, also the PCI card has to have the correct drivers installed and probably your card let Windows install its own drivers. The link that Ann posted should have the information to solve your problem, I have looked though it and it uses the same process that I used on my old Win7 PC when a new PCI Firewire card did not work after I fitted it. If this does not work for you then a new card PCI with Texas chipset may solve your problem

Unable to capture video from canon xha1s to final cut pro 6.0. so confused

hi,
i purchased a canon xha1s and am simply trying to capture the video onto my macbook pro laptop. i keep getting the error saying my settings are incorrect and am confused as what to put and where. i went to the video/audio settings and put what i believed to be correct (HDV) since my camcorder records in HDV. still that error window pops up when i try to log and capture footage.
any help would be greatly appreciated!

Hi .. I had a very similar problem .. if the above fails it may be worth a look at this too..

Selecting microphone when capturing video from the webcam

Using Final Cut Pro X
I want to capture video from my webcam into Final Cut. I have a USB microphone (Yeti) with which I want to record the audio. I cannot find an option to select my input source for audio when capturing this footage. Final Cut seems to default to my microphone on my webcam, which causes echoing and noise. I can select the USB mic when doing a voiceover, but when I capture video I cannot find an option to select my input. I've made my USB mic my default device in Sys Prefs, but that doesn't work. Any other ideas?
Options
1. Figure out how to change the default input for webcam capture in Final Cut
OR
2. Use another program. I've also tried to do the same in both QuickTime and iMovie, and they both capture audio only from the webcam as well.
Everything I've found online talks about voiceover. I don't want that. I want to capture video with it.
Suggestions are appreciated. Thank you.

Thanks. Don't know why I didn't see it. That arrow is pretty small.
I do still have an issue that I cannot figure out. I'm using the same mic for webcam recording (now in QT thanks to Luis) and in Final Cut for voiceovers. Though I'm still on the same Mic the sound is not the same. It's close, but the sound on the voiceover sounds cleaner and clearer. I'm sitting in the same spot speaking the same way, but the sound quality difference is noticable. Not sure why.
It seems that the difference is in how each software deals with it.
It may be that QT is sampling audio differently from FCP X somehow, or using a different audio codec or whatever.
Just guessing, I really have no concrete knowledge.
Oh, wait: there are a few things that I can notice, after trying a small example: the QT audio is AAC at 44.1 KHz,
the FCP X is AIFF at 48KHz. Compression and sample rate are different.

Unable to capture video

I have FCP HD 4.5. I am trying to capture video from a camcorder. I can connect the camera to my iMac via the cameras DV port into the firewire port or by the camera's USB port into the computer's USB. I have tried both ways but the camera is not being recognized. The camera is a Canon Elura 80, mini DV.
I select Log and Capture and I am told it is "unable to recognize video deck." Then I try Capture Now but it says video device isn't selected. What should I do?
Thanks

You have two problems that fold into one another masking the solution.
1. an intermittant connection between your camera and the computer
2. a possible conflict between your camera and an external drive.
Lets take the problems individually.
1. An intermittant connection. If your camera is not being recognized in system profiler (before trying iMovie or FCP) you have a connection issue. Either the camera settings are wrong, the camera's firewire port is damaged, your firewire cable is flakey and/or your computer firewire port is damaged.
To test these items individually, you'll need another computer, cable and camera that you know work. If you don't have these things or have access to them, you'll probably need to take your machine to a knowledgable repair shop.
2. A conflict between the camera and the hard drive. If the camera connects reliably and shows up in system profiler, it should always work with iMovie- even with a hard drive attached. This is the very first test. If it now doesn't work when you try it in FCP with the hard drive attached, you have the firewire bus conflict. Disconnecting all external hard drives from the computer and capturing to an internal drive will solve the conflict problem.

View video from webcam while transmitting

Hi everyone, when I try to use AVTransmit3.java and Clone.java (example from sun) to see video from webcam while transmitting, an error occur:
{color:#ff0000}+java.lang.NullPointerException+
at com.sun.media.codec.video.colorspace.RGBConverter.process(RGBConverter.java:352)
at com.sun.media.BasicFilterModule.process(BasicFilterModule.java:322)

So I'm only able to see in local my captured video, but cannot transmit.
I try to debug JMStudio to find how to do this(monitoring transmitted video), but I'm not able to debug it.
In method private String createProcessor() of AVTransmit3.java I added

            if (clone == null) {

I post all the class I use in this project.
Copy and create your own project (SERVER side)
Then on other pc (CLIENT side) run JMStudio and open RTP transmission: you will receive data but on server you will have a black window.
I've modified only AVtransmit3.java -> look at Main() and modify dest-ip and port.
JFrameMain is a class with a button to close the application.

Hi guys,
need bit help in resolving query related to custom added field in Tcode migo.
i have added a field in migo at item level ,in this i have used drop down list
to get data but unable to capture data from drop down list.gown through
many blogs in scn but unable to resolve.
Please help me out in this.
Thanks,

Error- "Unable to capture video..."

What is the solution to allow video capture in the preferred WMV mode. I know AVI mode works but compression sucks. Plus, my laptop was always able to capture vid in WMV until recently.
Now i get this error!!!!!!!!!!! Pls advice on this error:
"Unable to capture video. Pls check hard disk space and the following are set correctly: video/ audio compressor"
I know I am not the only one with this issue. yes, already tried uninstalling/reinstalling drivers and software fron the Creative website.
THanks a lot for solutions!

Unable to delete videos from my iad

I am unable to delete videos from my ipad. When I go to Settings - Usage - Storage; the video section will show up as no data in it even if it has multiple videos downloaded from itunes in it. I am using iOS 7.0.4 on a new iPad mini Retina 64GB. I am seeing the same problem on my iPhone 5S.

I was puzzled by this since ios7 I waited for 7.1 and thought it was fixed as it seems to go away. Now its back in 8.0 and 8.0.2.
It seems somewhat related to incomplete accounting of downloaded video and music too on the device and applying to storage left on device as these two icons are not showing up under usage in settings, even with show all selected.
Here is what I did:
Go to "Videos" under settings, turn off "show all videos", this will show only videos that presumably are on your device.
Go to Videos" app and you should see video that is presumably downloaded to device, select the cloud icon and as unintuitive as it seems, download the video as if it is not already on the device.
When one or all of your videos finish, go to "Settings", "General", "Usage", you will see an increase in available storage.
While there, select "Manage Storage" and "Videos" should show up in usage and an amount of MB or GB.
Select "Videos" under storage and your videos will present. Select "Edit" in upper right corner.
Select red "minus symbol", delete.
As you do this you will see more and more of your devices storage coming back in available storage.
This is similar to or is a memory leak issue that needs to be addressed. It apparently hasn't yet.
The same process works with Music. I haven't seen this as an issue in dealing with apps.
