MythTV Frontend shows blackscreen

I have an SAA7130 card and load the module saa7134 with card=3 option to use my TV card.
I know TVtime works with it, and so does mplayer.
I'm trying to configure MythTV. It is able to scan the channels but mythfrontend does not do anything, I see a black screen for a few seconds and then it goes back to the menu.
Here are the two main errors that I see in mythfrontend:
TV Error: StartRecorder() -- timed out waiting for recorder to start
TV Error: LiveTV not successfully started
and the mythbackend log:
format_to_mode() does not recognize V4L1
LoadFromScheduler(): Error, called from backend.
NVR(/dev/video0): Unknown video codec. Please go into the TV Settings, Recording Profiles and setup the four 'Software Encoders' profiles. Assuming RTjpeg for now.
Please help me fix this.
Also this server does not run xserver as such, I use ssh X11 forwarding to run GUI software.

Hi,
I have the exact same problem. I did a quick google and think this maybe relevant:

Built-in iSight showing blackscreen.

Hey all,
The problem just surfaced last month, when i would open photobooth,ichat,skype.etc. The green LED light will turn on, but it would just display a blackscreen on the programs.
I tried everything, resetting SMC, and the applealt+pr on the chime...EVEN did a clean install..and it started working on the welcome screen when it asks you to take a picture, and after the welcome box, i opened photobooth and boom
what should i do???
last resort is to send in for repair, but i have tonssss of work to do, can;t afford to

Welcome to Apple Discussions, wkim8732
Assuming your problem is with a built-in iSight, with all you have tried, your Mac may have hardware problems that require professional service.
Disconnect all peripherals other than your keyboard, mouse, and internet connection. Then restart your Mac and try the suggestions in Apple's How to Troubleshoot iSight. If the reset suggested there still does not correct the problem, use the other suggestions to find out if your problem is application specific or, perhaps, is a problem with your user account.
If you iSight works doesn't work in any app in any user account, check whether it shows in your System Profiler as a USB Device. Your iSight's info should look similar, but no necessarily identical, to this picture:
If iSight doesn't show in System Profiler and doesn't work in any app, contact Apple or an Apple-Authorized Service Provider for service. The service technician may be able to tell you how long you should expect the repair to take from talking with you or from a quick initial inspection of your Mac.
If I understand your post correctly, you iSight actually worked while you were initializing your reinstalled software but then quit again. If so, and if you used Archive & Install, you might be able to get your Mac going again by reinstalling again using a differnet method.
Backup your important files first!
For this reinstall, start by zeroing your disk to remove any possible problem info. Depending on the size of your hard disk, zeroing can take several hours, so plan accordingly. Then perform a clean install onto your newly erased hard disk, but do not migrate your information and settings from the same backup you used before or a backup you just made. Doing so might copy the problem back to your newly installed system along with your good information.
Instead, use a known good backup or initialize manually so you are certain you do not move bad info to your clean install disk.
You will also have to reinstall your applications from their original sources rather than migrating your applications and settings from a backup or another Mac.
As you can see, this process will be time consuming compared to Archive and Install, but it is the only way I know to be certain you have not kept or restored bad info that may be causing your problems. If a clean install onto a zeroed disk does not cure your problem, you will need professional help unless you are willing to use your Mac without a working iSight.
If you choose to continue to use this Mac with iSight or other functions not working, I suggest that you backup more frequently and also to more than one other hard drive in case more problems develop.

How much system RAM for Arch-based MythTV box?

I'm thinking of using an older (not too old) computer I have sitting around to build a MythTV box. My current question is about the specs necessary to make this useful for everyday capture/playback, and other normal HTPC related tasks. So, how much system memory do I need? 512MB, 1GB, more? Oh, and what about CPU? I've got and old Athlon XP 3200+ that I'm not using. Would that work well? My budget is basically USD $200-300 for new parts and the rest must come from my personal parts surplus.

My mythtv frontend was an Athlon 1400+ with 512MB of RAM. It was more than adequate... though I doubt it would be for HD recordings.
You'll be fine.

[SOLVED] Timezone issue with Mythtv

I've just gotten home and have gone to use Mythtv frontend in the lounge room but I am getting the issue:
Your frontend and backend are configured in different timezones. You must correct this mismatch to continue
This has also recently happened on the frontend out the backroom but I haven't had a chance to look at it. But now that the one in the lounge room has done it I will have to get it sorted. I use NTP on the system to keep the time in sync but it doesn't seem to be the issue. Seems to be related to Mythtv. I haven't changed anything on the system at all.
My system is still using rc.conf
So I am hoping someone might be able to help me correct this issue?

[SOLVED] No "Custom Filters" in MythTV menu

Hello.
I am currently trying to make my MythTV frontend play HD videos smoothly and the MythTV wiki says that I should try adding "vdpaubuffersize=32" if I suffer from artifacts (which I am at my HD anime). According to the MythTV docs there should be an option called "Custom Filters" in Setup->TV Settings->Playback, but I cannot find any text field for filters there.
I am asking this question here, because I guess that the archlinux version of MythTV is somewhat special. A mythfrontend --version results in:
Please attach all output as a file in bug reports.
MythTV Version : Unknown
MythTV Branch : branches/release-0-23-fixes
Network Protocol : 23056
Library API : 0.23.1.201000710-1

I am using the plugin "mythplugins-mythvideo" from pacman for playback of local videos.
Do you know if the option has moved somewhere else, where I have not found it yet? or I need to enable something?

Thanks a lot, I would not have found it there… I often was in that menu but I did not pay attention that there is a "next" button even in the submenu.
Seemed to work, I do not see any artifacts anymore in my 720p videos (mkv) after having added vdpaubuffersize. With the new value the CPU also remains at about 5-10% (on one core) even at 1080i (Big Buck Bunny, H264). Elephants Dream still goes much higher, but still seems to play smoothly.

Computer Freezes using Sound Soap 2

* I have previously posted this question on the Final Cut Pro discussion forum but also wanted to post it here since my entire computer seems to freeze up when I apply this app. (not just Final Cut Pro). So here goes...
I'm wondering if anyone else has run into this situation....
When I go to apply my SOUND SOAP filter to an audio clip in my timeline, FCP slowly begins to show strange behavior. This is what happens:
1). I can no longer access features using keyboard shortcuts
2). Eventually I am no longer able to access drop down menus from the top bar (File, Sequence, Effects, Modify, etc)
3). Pretty soon I am no longer able to even save my work and very soon after that, my computer freezes up all together and even a FORCE QUIT doesn't work. I end up having to shut off the computer cold, unplugging it for a few minutes and then plugging it back in.
From there the FCP software and computer work fine.
When I don't apply a sound soap filter, things run fine. When working in another project (that doesn't have audio clips with Sound Soap on them), things work fine. It's just when I work with projects containing sound soap clips that things start to get weird.
Has anyone else had this problem with Sound Soap 2? Technically I could have posted this question under the USING YOUR MACPRO thread but since it was affecting FCP, I thought it was relevant here.
I have a MacPro 2x2.8 GHz Quad-core Intel Xeon with 4GB 800 MHz DDR2 FB-DIMM and I'm running FCS2 version 6.0.5 under MacOS X (10.5.7)

Same here. I called Apple phone support today and they confirmed it is a known issue that is being worked on. No possibility to get an update on when this issue is resolved.
Just out of curiosity, apparantly this is not an issue for everyone otherwise there would be more views and replies in this forum. So what could we have in common:
* I upgraded from Leopard.
* Did you install any additional media players? I installed vlc, mythtv frontend and Quicktime 7 legacy support from the optional software on the snow leopard install CD.
* Do you have a recent model (i bought my Mac Book Pro 2 weeks ago)
Best regards,
Dirk-Jan

Reporting time taking too much time

Hi Experts,
I created one query one of my data target and i executed query, it takes too much time, can any one tell me how can i resolve this issue? please help me out?
Thanks in advace
David

Check if the IC data is compressed or not?Compression will increase the performance of the query.
Check for the stats info using ST03 and analyse what need to be done .creating aggregates etc..
Use ST03N -> BW System load values to recognize the problem. Use the number given in table 'Reporting - InfoCubes:Share of total time (s)' to check if one of the columns %OLAP, %DB, %Frontend shows a high number in all InfoCubes.
You need to run ST03N in expert mode to get these values
based on the analysis and the values taken from the above - Check if an aggregate is suitable or setting OLAP etc.
Check the read mode for the query. recommended is H.
If the Query is built on the top of MP then
- including characteristic 0INFOPROV when you design the query for the MultiProvider so that you can filter by InfoProvider.
- Do not use more than 10 InfoProviders when you define a MultiProvider. If a number of InfoProviders are being read by a query at the same time, it can take a while for the system to calculate the results.

How can I play blu-ray? - software advice

Hi,
I've just got hold of a pioneer blu-ray player for my PC. I've got an Nvidia 7900 GT/GTO and an old-ish bug Compaq 21" CRT.
I say a posting on the Ubantu about Feisty Fawn ??https://help.ubuntu.com/community/RestrictedFormats/BluRayAndHDDVD
I was wondering if anyone knows how to do this on Arch and can give me some details?
cheers

You'll also need HDCP-compliant hardware, so an oldish box won't cut it . The whole 'chain' of devices needs to be 'trusted' if you really want to play off the disc itself instead of ripping it.
Blu-Ray opticals > motherboard > HDCP-compliant output (I think that's the most important but not sure). Plus, you need a lot of processing power. Blu-Ray uses a h.264 codec, that can get quite beefy.
I sort of covered that already FWIW, Vista did play a BluRay as well as HD-DVD but it failed at playing the whole movie. More testing to be done. *IF* Vista is the only answer for BluRay then I'll be waiting until I can get a decent deck under $200 before buying any more BluRay discs.
GeForce 7000 & 8000 series sometimes have HDCP compliant DVI ports which can be adapted to HDMI as well. You just lose the audio stream. Certain Intel video chipsets also have the support. Don't personally know which ATI cards support it as I've always used Nvidia for my linux boxes except my new MythTV frontend which uses the board mentioned above.

Inventory Ageing query performance

Hi All,
I have created inventory ageing query on our custom cube which is replica of 0IC_C03. We have data from 2003 onwards. the performance of the query is very poor the system almost hangs. I tried to create aggregates to improve performance but its failed. What i should do to improve the performance and why the aggregate filling is failed. Cube have compressed data. Pls guide.
Regards:
Jitendra

Inaddition to the above posts
Check the below points ... and take action accordingly to increase the query performance.
mainly check --Is the Cube data Compressed. it will increase the performance of the query..
1)If exclusions exist, make sure they exist in the global filter area. Try to remove exclusions by subtracting out inclusions.
2)Check code for all exit variables used in a report.
3)Check the read mode for the query. recommended is H.
4)If Alternative UOM solution is used, turn off query cache.
5)Use Constant Selection instead of SUMCT and SUMGT within formulas.
6)Check aggregation and exception aggregation on calculated key figures. Before aggregation is generally slower and should not be used unless explicitly needed.
7)Check if large hierarchies are used and the entry hierarchy level is as deep as possible. This limits the levels of the hierarchy that must be processed.
Use SE16 on the inclusion tables and use the List of Value feature on the column successor and predecessor to see which entry level of the hierarchy is used.
8)Within the free characteristics, filter on the least granular objects first and make sure those come first in the order.
9)If hierarchies are used, minimize the number of nodes to include in the query results. Including all nodes in the query results (even the ones that are not needed or blank) slows down the query processing.
10)Check the user exits usage involved in OLAP run time?
11)Use Constant Selection instead of SUMCT and SUMGT within formulas.
12)
Turn on the BW Statistics: RSA1, choose Tools -> BW statistics for InfoCubes(Choose OLAP and WHM for your relevant Cubes)
To check the Query Performance problem
Use ST03N -> BW System load values to recognize the problem. Use the number given in table 'Reporting - InfoCubes:Share of total time (s)' to check if one of the columns %OLAP, %DB, %Frontend shows a high number in all InfoCubes.
You need to run ST03N in expert mode to get these values

[SOLVED] Synaptics touchpad problem eeepc 1000HE

I installed Arch on my eeepc 1000HE yesterday and configured / used it happily for most of the day - but then it developed a touchpad problem which I'm struggling to fix.
If you lift your finger from the touchpad the mouse cursors 'forgets' / 'resets' its position.
eg When you put your finger back on the touchpad the cursor jumps to a different position. For one thing, this means you can't tap to click, because when you lift your finger to tap, the cursor jumps somewhere else (usually a slight move, but usually away from the item one wants to click).
Also, when needing a few swipes (eg to move the cursor left to right across the screen), the cursor jumps away from its current position (to the left - sort of back to its original starting position) each time I lift my finger to make the extra swipe.
The problem seems to have started when I had a tv plugged in via the vga and was managing screen switching with xrandr and the screen-switch function key (I'm trying to set up the eeepc as a mythtv frontend) but this could be coincidence.
Some settings etc -

I thought the issue might be related to this https://bugs.archlinux.org/task/20830 , but adding MatchDevicePath "/dev/input/event*" to /etc/X11/xorg.conf.d/10-synaptics.conf didn't make a difference.
My Daemons array looks like this -

Removing the ! before hal made no difference.
I am using gnome. Changing the settings in the /desktop/gnome/peripherals/touchpad/ folder with gconf-editor makes no difference to the problem.
I am using kernel 2.6.38-ARCH. Using the fallback kernel didn't help.
Any help would be much appreciated.
Thanks

Update. After some more searching the forum I thought downgrading udev may help. Since I had a fresh install I needed to install the AUR downgrade package. I did a yaourt -Suy before doing so which, amongst other things, installed a new kernel (4-1) and upgraded yajl. When I tried yaourt -S downgrade I got an error re yajl - error while loading shared libraries libyajl.so.1, canot open shared object file, no such file or directory, and then "error: target not found: dowgrade".
Any help really appreciated.

Can't mount NFS from my Arch laptop, am I missing something obvious?

Hello,
I have been trying to solve this issue for over a week and tried everything that I can imagine with no luck...
Set up:
- Qnap SS-839 Pro with several NFS shares on
/share/to_sort
/share/movies
/share/music
etc.
- MythTV frontend/backend running Mythbuntu.
I can mount my NFS shares without problem. I use this fstab.
192.168.1.100:/share/Music /var/lib/mythtv/music nfs nolock,async,proto=tcp,rw,ac 0 0
192.168.1.100:/share/Videos /var/lib/mythtv/videos nfs nolock,async,proto=tcp,rw,ac 0 0
- Arch laptop
I can't get to mount any of the NFS share:
[18:59:14][[email protected]]
/mnt/aether Arch64# /etc/rc.d/rpcbind restart
:: Stopping rpcbind [DONE]
:: Starting rpcbind [DONE]

/mnt/aether Arch64# mount 192.168.1.100:/share/to_sort/ to_sort/
mount.nfs: rpc.statd is not running but is required for remote locking.
mount.nfs: Either use '-o nolock' to keep locks local, or start statd.
mount.nfs: an incorrect mount option was specified

/mnt/aether Arch64# mount 192.168.1.100:/share/to_sort/ to_sort/ -o no-lock
mount.nfs: an incorrect mount option was specified
I tried using the 2 following lines in my fstab on my laptop but nothing works:
1) 192.168.1.100:/share/to_sort /mnt/aether/to_sort nfs nolock,async,proto=tcp,rw,ac 0 0 (same option than under mythbuntu)
2) 192.168.1.100:/share/to_sort /mnt/aether/to_sort nfs defaults 0 0
I'm no guru when it comes to nfs sharing etc, but I really can't see what I am missing here, nor whatelse can I try!
Any idea will be more than welcome!
Thanks in advance

As you can see, it is now working and I am now completely puzzled...
How come reinstalling this package solved the issue?
Any idea on what the problem was would be more than welcome
Thanks

Iphone5s get hanged on restart

my iphone5s get hanged and its showing blackscreen into apple logo and this happens when i reset the iphone anyone tell me how to repair the iphone

Hi karthi1494,
Thank you for participating in the Apple Support Communities.
If your iPhone 5s is becoming unresponsive and only shows a black screen or Apple logo, the advice in this article can help:
If your iPhone, iPad, or iPod touch doesn't respond or doesn't turn on - Apple Support
All the best,

BBC One Keeps needing pin

so far i am far from impressed since software release.
Box keeping locking up - Always need to hard reboot
Box keeps failing in it records - Records and saves but only shows blackscreen from teh recording
However, one issue is really peeing me off..... Every time i change channel and want to go back to BBC one it keeps asking for pin regardless of time of day
On my settings i have only got "rental" requires pin, nothing else is activated IE age restriction and such.
Anyone else seen this issue??? its seriously begin to annoy me 'n' missus
Finally dont know if its related, but since the software upgrade to BT vision my broadband is also going down the pan, in last 4 days i have had to reboot my Hub no less than 14 times, prior to that i might have done 1/2 reboots in previous 6 months.
Anyone else seeing these issues, or offer advice on the bbc one problem
cheers
Solved!
Go to Solution.

oops do i feel a numpty now,
thanks can you mark that bit as solved.. obivously the longer term issues are still as per original post

How to improve Query Performance

Hi Friends...
I Want to improve query performance.I need following things.
1.What is the process to findout the performance?. Any transaction code's and how to use?.
2.How can I know whether the query is running good or bad ,ie. in performance praspect.
3.I want to see the values i.e. how much time it is taking to run?. and where the defect is?.
4.How to improve the query performance?. After I did the needfull things to improve performance, I want to see the query execution time. i.e. it is running fast or not?.
Eg..
Eg 1.   Need to create aggregates.
Solution: where can I create aggregates?. Now I'm in production system. So where I need to create? .i.e. indevelopment or in Quality or in Production system?.
Any chenges I need to do in Development?.Because I'm in Production system.
So please tell me solution for my questions.
Thanks
Ganga

This is the oss notes of FAQ on query performance
1. What kind of tools are available to monitor the overall Query Performance?
1.     BW Statistics
2.     BW Workload Analysis in ST03N (Use Export Mode!)
3.     Content of Table RSDDSTAT
2. Do I have to do something to enable such tools?
Yes, you need to turn on the BW Statistics:
RSA1, choose Tools -> BW statistics for InfoCubes
(Choose OLAP and WHM for your relevant Cubes)
3. What kind of tools is available to analyze a specific query in    detail?
1.     Transaction RSRT
2.     Transaction RSRTRACE
4. Do I have an overall query performance problem?
i. Use ST03N -> BW System load values to recognize the problem. Use the number given in table 'Reporting - InfoCubes:Share of total time (s)' to check if one of the columns %OLAP, %DB, %Frontend shows a high   number in all Info Cubes.
ii. You need to run ST03N in expert mode to get these values
5. What can I do if the database proportion is high for all queries?
Check:
1.     If the database statistic strategy is set up properly for your DB platform (above all for the BW specific tables)
2.     If database parameter set up accords with SAP Notes and SAP Services   (EarlyWatch)
3.     If Buffers, I/O, CPU, memory on the database server are exhausted?
4.     If Cube compression is used regularly
5.     If Database partitioning is used (not available on all DB platforms)
6. What can I do if the OLAP proportion is high for all queries?
Check:
1.     If the CPUs on the application server are exhausted
2.     If the SAP R/3 memory set up is done properly (use TX ST02 to find bottlenecks)
3.     If the read mode of the queries is unfavourable (RSRREPDIR, RSDDSTAT, Customizing default)
7. What can I do if the client proportion is high for all queries?
Check whether most of your clients are connected via a WAN connection and the amount of data which is transferred   is rather high.
8. Where can I get specific runtime information for one query?
1.     Again you can use ST03N -> BW System Load
2.     Depending on the time frame you select, you get historical data or current data.
3.     To get to a specific query you need to drill down using the InfoCube name
4.      Use Aggregation Query to get more runtime information about a   single query. Use tab All data to get to the details.   (DB, OLAP, and Frontend time, plus Select/ Transferred records, plus number of cells and formats)
9. What kind of query performance problems can I recognize using ST03N
   values for a specific query?
(Use Details to get the runtime segments)
1.     High Database Runtime
2.     High OLAP Runtime
3.     High Frontend Runtime
10. What can I do if a query has a high database runtime?
1.     Check if an aggregate is suitable (use All data to get values "selected records to transferred records", a high number here would be an indicator for query performance improvement using an aggregate)
2.     o Check if database statistics are update to data for the   Cube/Aggregate, use TX RSRV output (use database check for statistics and indexes)
3.     Check if the read mode of the query is unfavourable - Recommended (H)
11. What can I do if a query has a high OLAP runtime?
1.     Check if a high number of Cells transferred to the OLAP (use "All data" to get value "No. of Cells")
2.     Use RSRT technical Information to check if any extra OLAP-processing is necessary (Stock Query, Exception Aggregation, Calc. before   Aggregation, Virtual Char. Key Figures, Attributes in Calculated   Key Figs, Time-dependent Currency Translation) together with a high number of records transferred.
3.     Check if a user exit Usage is involved in the OLAP runtime?
4.     Check if large hierarchies are used and the entry hierarchy level is as deep as possible. This limits the levels of the hierarchy that must be processed. Use SE16 on the inclusion tables and use the List of Value feature on the column successor and predecessor to see which entry level of the hierarchy is used.
5.     Check if a proper index on the inclusion table exist
12. What can I do if a query has a high frontend runtime?
1.     Check if a very high number of cells and formatting are transferred   to the Frontend (use "All data" to get value "No. of Cells") which   cause high network and frontend (processing) runtime.
2.     Check if frontend PC are within the recommendation (RAM, CPU MHz)
3.     Check if the bandwidth for WAN connection is sufficient

Screen recorder for iphone 4 ios7

I heard about reflector. But it requires iphone4s minimum. I also tried to use software https://github.com/coolstar/RecordMyScreen to record, but it shows blackscreen because after doing research, it seems apple banned screen recording software from third party or something. It is only available for ios6. I tried to downgrade to ios6, but apple wont allow me to do that. So is there any solution?I appreciate for your help. Thank you.

Try This http://www.oldapps.com/itunes.php For Windows and for Mac http://www.oldapps.com/mac/itunes.php
Hope This Works And Good Luck!
