Help! - Problem with TV capture following Noodle upgrade

Hi All,
Hoping someone here can help me with a little problem i've found after upgrading to 'Noodle'.
After upgrade and switching to hwd from hotplug the bttv driver seems to be loaded okay for my Leadtek Winfast XP and i can see and hear TV using tvtime as before, (had to alsaconf after upgrade to get sound from my soundblaster live but otherwise ok).
My problem comes when i use the following command to try and capture TV:
mencoder -tv driver=v4l2:width=640:height=480:device=/dev/video0 -vf crop=760:568,pp=lb -ovc lavc -lavcopts vcodec=mpeg4:vqscale=6.1:vbitrate=2000 -oac mp3lame -lameopts abr:br=80 -o output.avi tv://
I've been uisng this command perfectly well up unitl this weekend when i took the plunge and upgraded. Since then i can capture the video from the TV card but the resulting capture never has any sound???
Prior to the upgrade i would have to adjust my volumes manually via the gnome volume control, lowering my master and PCM feeds and upping the Line and Capture options in the capture sections. This was to ensure the volume on my captures was not too loud, but it makes no difference now as i get no audio fullstop..
[edit]
For the record i have not upgraded mplayer to the latest version due to incompatibility with other scripts i use. The version i'm using is: MPlayer 1.0pre6-3.4.3.
I might try and upgrade this incase its an mplayer prob with the rest of the system, which maybe fixed in the current version.
[edit]
I suspect this is a problem caused by udev or a missing device and or rights issue, but unfortunately after hours of slaving i have not made any headway and i'm not sure where to go from here. I was hoping someone maybe able to explain whats happening and perhaps offer a solution.
Its as if mencoder is trying to get the audio from the wrong feed or something???
Any help would be greatly appreciated.
Regards
Spitbyte
PS: I have removed and reinstalled alsa and also reconfigured several times using alsaconf.

Nope, it does exactly the same as root. So i guess its not a permission related problem. Thanks for the idea though
I've just found this site:
http://www.linuxtv.org/v4lwiki/index.php/TVCapture_98
and played with the amixer commands.
I have the capture options exactly as they say, save for the ID is 68. I have tried all the options 1 thru 7 and can't get an audio stream on any. (ive also adjusted volume levels)
I also noticed that there was a separate option in the full amixer listing (amixer controls) for Line playback. Out of curiosity i ran tvtime and then adjusted the volume of the Line playback option via amixer and this lowers the volume that tvtime is using.
This is interesting as i thought tvtime was using the capture channel for audio, it obviously is not and thats why i can get a feed with tvtime and not with mencoder.
So my TV card must be okay as i'm definately getting sound from it to my soundcard. The issue looks to lie with the soundcard. However, i've tried capture on my onboard sound and this does not work either. What are the chances of both sound chips failing, unlikely me thinks.
So again, i'm coming back to the idea that something has not been loaded that allows capture????
Also, if i try and watch tv via mplayer (mplayer tv:// -tv driver=v4l2:width=768:height=576:outfmt=yuy2 -vf pp=lb), then i get no sound. I'm trying to work out how to specify to mplayer which audio source to use but i'm getting lost in the man page a little (sooooooo many options ), i believe tvtime (as per man page) uses '/dev/mixer:line' as its default feed and this works, so i've just got to try and work out how to define this within the mplayer command to see if i can get sound.
My next step after this would be to see if i can route the line playback feed to mencoder for capturing ????
I dunno if i'm getting anywhere, but i'll soldier on. Please help if you can
Regards

Problems with Bluetooth mouse following Lion upgrade

I upgraded my MacBook Pro from Snow Leopard to Lion, this morning, and now my Kensington Bluetooth mouse, which I have been using for nearly 2 years, has stopped working. The upgraded MacBook now only registers a connection with the mouse if it is held within about 10cm of the system, but even then it doesn't respond to any movements of the mouse. I have previously been using the mouse quite happily from a distance of about 50cm.
Is this a known problem associated with Lion?

Well, after 2 days of completely refusing to work, the mouse suddenly requested Bluetooth pairing, and has worked ever since. I don't know why it took 2 days, though.

I'm having a problem with device capture

I'm having a problem with device capture. I connect my Sony HC-90 via firewire. I can start the capture process in Premier 4 but then all control freezes.

Are they custom EQ settings in iTunes on the computer?
Per:
https://discussions.apple.com/message/17383922#17383922
"Do the EQ settings from my iTunes library transfer to my iPhone when I sync it"
Yes.
" thus causing my iPhone to over process the data when I turn it's EQ on? "
No. If the EQ ison, the iPhone will use the EQ setting you assigned in iTunes. It will use only the preset EQ. If you have a custom setting or do not have an EQ setting, it will not be used and will use the setting on the iPhone.

Problem with Video capture Device

i have a problem with FME. i am using Avermedia TV capture
device and Canon 3ccd Digital Video Camcorder ( PAL ) when i open
the FME interface the warning given for " Problem with Video
Capture Device".
i read all the topics in Flash Media Encoder Category, if
this problem occures my capture device ( i expect MPEG ) how to
solve this problem?
Thanks,

The Device Matrix is something we'll be updating in the
future as we continue to test more and more equipement. Ideally, I
would like for users such as yourselves to be able to add to it and
tell us what has worked for you as well. If anyone has any ideas
about what technology we should use to do this (e.g., this forum? a
wiki?) please let me know.
Regarding the devices not working - the main problem we see
is that the system requirements are not being met. Here is what to
check for:
- are you running on Windows XP (only supported OS right
now)?
- do you have DirectX client runtime version 9c or higher
installed?
- do you have hardware acceleration enabled?
- do you have 32bit graphics enabled?
- do you have the latest direct show drivers from the
card/device manufacturer?
Thanks,

FMLE 3.0.0.4743 Problem with video capture device

Tue May 05 2009 14:26:54 : Selected audio input device: Beholder Aud Capture (SAA7135)

Flash Media Encoder 2.5 working without any errors

The second message that you are getting "The selected audio device "Beholder Aud Capture (SAA7135)" doesn't allow setting volume intensity. Disabling the volume slider control." is because your device does not let you change intensity of volume. This warning message is just to tell user that volume slider will remain disabled for the selecetd device. This is new addition in FMLE 3.0 and was not there in FMLE 2.5
Also for first message, please make sure that no other instance of FMLE is already running using this device. You can verify this from task manager. If any other instance of FMLE is running then please close that instance so that device gets free for new instance.

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 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?

Problem with Video Capture, and question towards solution

Yesterday I worked on a commercial for which we captured 9 clips (roughly 10 seconds or shorter in length). The clips all had text/titles superimposed on them by an outside machine and looked good in the monitors when they were exported and captured into FCP (ie: none of the text was chopped off).
I edited the commercial and then was exporting it out, only to discover that the text on the bottom of the clips was getting chopped off.
My first question is this: is there some setting in the capture process that could have done this? something that might have gotten tweaked accidently, or corrupted in some manner? Didn't have this problem with footage captured the previous day. And since it looked good before it was put into FCP, thinking it had to be a problem with FCP.
Also, in trying to tweak the footage in FCP, I came across a 'there must be an easier way to do it' question. Is there a way to alter parameters on multiple clips (such as raising them, like I had to)? I tried selecting all and double clicking, hoping that the changes I made would affect them all, but it only affected the one I directly clicked. I'm sure there's something simple (and obvious) that I'm overlooking...
thanks!

For how and why this could have happened, would you mind sharing your capture and sequence settings?
As far as applying parameters to multiple clips, I think you can make use of the Paste Attributes function in FCP...
Alter one of your problematic clips
Select that clip in the Timeline, then press Command-C (or control-click and choose Copy from the contextual menu)
Select the remainder of your problematic clips
With your clips selected press Option-V (or control-click on one of them and select Paste Attributes from the contextual menu) to bring up the Paste Attributes dialog
Select Basic Motion - under the Video options, on your left-hand side - then click OK
(Basic Motion because, if I understand your solution correctly, you altered the Center property - either in the Motion tab of the Viewer or manually in the Canvas - of your clips. You nudged them all up a bit, right? If you did, then that would fall under the Basic Motion attribute.)
All your selected clips should be nudged up appropriately.
But, again, I'm making a bit of leap since I'm not entirely sure what caused your issue in the first place.

Problem with change capture

HI,
we've a problem with the Change Capture in the DAC's Execution Plan.
We've cretead a new data model but we want to reuse the image table and the Change Capture process, so we've perfomed the following step:
1) create the mapping SDE e SIL for the new tables of datamodel in Informatica Power Center
2) register these mapping in the DAC
3) create a subject areas and associate these tasks to this
4) create execution plan including "change capture" and "change capture sync"
5) execute our "execution plan"
the problem is the following:
from the Execute -> Current Run Tab -> task
we can see that execution time of change capture is 0
from the Execute -> Current Run Tab -> task details
there aren't any change capture details
So, our image table are empty.
Do you have any idea?
Thanks in advance,
Antonello.

HI Antonello,
I am also having the same issue like you. I have created a new execution plan in DAC 101341 and ran it. It seems like the task Change Capture For Siebel OLTP completed in 0 seconds and there are no details for that particular task. Can you please let me know if you have resolved this issue? Your help is much appreciated.
Thanks

Problem with the USB-connection after upgrade to P...

Hello to everybody!
After upgrading PC-suite, I can't establish a USB-connection with the phone.
Here are the facts:
1) My phone is the E90. Latest software installed (300.34.84)
2) PC-Suite version 7.0.9.2 english. I also tried the greek version, same problem with it also.
3) Nokia Connectivity Cable Driver 7.0.2.1. I also installed manually a previous version of the driver (7.0.2.0), but this didn't solve the problem.
4) I didn't have any problem with the older version of PC-suite.
5) I don't have a problem with the cable because the data-transfer-mode works fine.
6) Prior to any installation attempt, I always first uninstalled PC-suite and Cable-driver manually with the windows-xp uninstall program. This was not the fact, only in my first attempt, where I upgraded the pc-suite from inside the program itself.
Please help, because I can't backup and this is very important for me!
Solved!
Go to Solution.

Thank you all for your suggestions but nothing of the above worked for me.
After of hours and hours of installing and uninstalling of several versions of the pc-suite I solved the problem as following:
1) Uninstall manually (windows - control panel - add/remove programs)Nokia-PC-Suite, Nokia Connectivity Cable Driver AND PC Connectivity Solution!
2) Restart PC
3) Download and install the new version of Nokia-PC-Suite.
The tricky part is that you have to uninstall the application called "PC Connectivity Solution" manually and since the title of the application dosn't include the Nokia-Name you have first to find out that this program is Nokia-related!
Once again, thanks to everybody who took the time to make suggestions and especially to cricfancy who made me aware of the fact that PC Connectivity Solution is a nokia application!
Finally, I would like to make a statement for Nokia:
People, if you are not sure about an update then keep it in beta and don't make it available to the public!!! I lost hours and hours on search and made countless installs and uninstalls to find out what was wrong. Under the line, I had made no mistakes in my update from the start and the whole problem was based on your software! This is not acceptable!

Stratosphere- Problem with Screen Capture and Group Text Reply

I have a problem with the side button that locks/unlocks the phone. I don't know why it happens but sometimes when I press the side button to lock the phone it takes a screen shot and send its to my Gallery under the folder ScreenCapture. I can't figure out why it does this sometimes, and when i want to actually take a screen shot I cant.
Anyone know how exactly you can take a screen shot?
Another question i have is with Group Texts. Is there a way to reply all when I receive a text that was sent to multiple people or can I only reply to the sender?
Hope someone can help thanks!

Hello kfeatherstone! I can provide you with instructions for taking a screenshot:
1. Press both the Power and Home buttons briefly.
2. You should hear a “click” sound and the screen will say “Screen captured. Saved as image file
In regards to your messaging, "reply to all" is not an available option. I hope this information helps!
