Developing streaming media servers in Java and JMF
hello.
this is james mcfadden. i've become interested in developing streaming media servers in Java and JMF. what good books and web pages should i read?
> i know that i can use J2SE in order to develop JMF
applications. i don't know if i use J2EE or J2ME to
develop streaming media servers. which version of
Java do i use.
Perhaps I didn't phrase my question correctly. What is your level of expertise and experience with Java SE?

The performance of management system with Java and MySQL
Hi all,
I want to develop one management application with Java and MySQL. However I am not sure which is a good way to design the system. The system has to deal with customers' data in the database.
Should I create objects for every customers when application starts so that I do not need to access to the database often? Or
Should I access to the database everytime the user want to deal with customer's data?
Welcome for any suggestion.
Thank you

Can I develop a driver mouse with Java?
Hi,
Can you tell me, if I can develop a driver mouse with Java and if not why and with which programming software?
And do you have a web site or forum reference about driver mouse?
Best regards,
Dimnet2000Aren't you all a little too hasty with your NOs?
If the task is to develop a standard plugged-in mouse driver you see and use everyday and that loads together with the bootup process of Linux, Windows... the answer propably is "No" or "better not".
Other than that... You can draw on the screen and you can communicate with the Serial Port. I think you could very well build your own mouse driver for a non standard Mouse to make it work in all Java applications. If you don't need 100% platform independancy you might think about building modules to trigger OS-Events via JNI.
For standard use this might not seem a sensible thing to do, but imagine if you are in some way handicapped and need a very special mouse that you want to carry around and use across several platforms without compiling and instaling drivers everywhere... -
Preview installation with ABAP, JAVA and EP
Hello all
I repost this topic to mark with the "question star".
I been inactive in the sneak preview area for a few month and I see here in SDN that a lot of new software is ready for download.
I have also read some of the postings from this forum, but I'm not sure what I need to have an installation with both ABAP, JAVA en EP.
Can anyone verify that I need:
1 server for the WAS 6.20 for ABAP
1 server for SAP Enterprise Portal 6.0 SP4 NetWeaver Stack 2 Developer Workplace Sneak Preview for JAVA and EP.
And that I can join the 2 systems via rfc or connectors.
Is it also possible to get a Sneak Preview to Web Dynpro (or is it included in the above) ?
Best regards
Thomas Madsen NielsenThe combined ABAP and JAVA stack Web AS doesn't support installation of EP on top.
If you want the features of both ABAP and JAVA stack in combination with EP then you will need two WebAS instances, one of those MUST BE Java ONLY!
I suppose you could manually club things together with SDM, but the installation program (SAPinst) in its current form is pretty specific in its checks for a JAVA only Web AS before letting you proceed with EP install.
I have not done a thorough check of the details on why you cannot run EP with Athe ABAP stack, it hasn't been worth the effort of trying....

JMF example AVTransmit2.java and AVReceive2.java is not working for me?
Dear all
I want to develop a class which will capture my voice data from my microphone and then will send it to the sound system of my PC following RTP protocol. For that I tried both AVTransmit2.java and AVReceive2.java class from http://java.sun.com/products/java-media/jmf/2.1.1/solutions/ but they just not doing it how I want, I am sure I am making some mistake, please let me know.
Moreover, when I try AudioBufferControl.java from the above link it is doing it for me what I want, let me hear what I am saying to my microphone, but it is using "javasound", I think that is not using RTP. Again if I use JMStudio even then I can hear my voice from microphone to sound system.
Pls can you help me write a class and let me know what I am doing wrong!
With care
Arif.Try to follow these steps:
1. make sure db tables have the pk and fk's pre-existing.
2. create a brand new workspace
a) Select New Business Components: business components from tables.
b) Select these two tables
c) on the define view pages (step 2), push both objects over, then just click [finish]
3. Open the ViewController Node
a) expand Web Content, then WEB-INF
b) double click struts-config.xml to open it
4. In Struts-config.xml
a) drop a datapage, name it BrowseRoster, double click it, then drag and drop the Roster table from your DataControl Palette, as a READ only table.
b) insert a column as the first cell in the table and drop the operation: setCurrentRowWithKey as a find Row link. This should create the ANCHOR link, i.e.
">Show Emps</a>
c) create another page, EditOneEmp, double click to open that, and EXPAND the Roster table in the Data Control Palette. Drop the Emp table on this as an input form.
d) Now go back to the STruts-config.xml and draw a forward from the browse to the detail and name the forward setCurrentRowWithKey.
e) run the browse page from the struts-config.xml file (right click and run). Click on the hyperlink and you should go to the detail input page.
You may have messed up in Step 4(c). Also, when you run into these situations, as we've run into this NUMEROUS times at work, follow through the examine again, IN A NEW WORKSPACE, and redo each and every step. You must be EXACT or things don't work.
Let me know if it works out.
Thanks. -
Some questions while using JMF play mpeg-1 stream media?
I use Helix server to provide unicast, and use JMF to play the stream media. But the JMF only play the audio stream transferred by rtp. I have used video palyer�s getVisualComponent() method to get Visual component and added it into the frame. But I get a pink screen. So I think some thing wrong with the video player.
Who can give me an answer?
1. Whether JMF can play mpeg-1 video stream media?( Audio can be heard. Video stream comes to my computer but can�t be displayed.)
2. Which method it should use to synchronize video stream and audio stream?
BTW: In JMF, when the RTSP player�s start() method is invoked, the player creates players by the stream�s track numbers. Video stream and audio stream have different players.Try posting your question under the Java Media Framework forum instead.
You'll get much better responses if you ask the right people !

Owen -

Linux 3.12 and streaming media on a Dell XPS 13: kernel panic
Hi all,
Shortly after upgrading from Linux 3.11.6 to 3.12, I started getting kernel panics while playing streaming media (in particular from Youtube and The Daily Show). Here is a camera shot. The crash would not take place immediatly, but perhaps after 15 minutes of streaming. After downgrading to Linux 3.11.6 everything works fine. Therefore, it is clear to me that the issue is related to the Linux 3.12 kernel, but this is all I know.
The fifth-to-last line from the camera shot reads:
[11438.332699] RIP [<ffffffff8129e160>] __sg_page_iter_start+0x20/0x20
A quick Google search reveals that __sg_page_iter_start is a function inside the scatterlist.h library in the Linux kernel, which apparently deals with memory paging, but my knowledge about this stuff is so poor that the message is almost meaningless. I would greatly appreciate if someone could give me a hint about this.
I did not find anything useful in the journal, but here are the last few journal lines for 2 different crash instances:

In the first journal log, the following line calls my attention:
Nov 15 00:26:02 xps kernel: perf samples too long (2530 > 2500), lowering kernel.perf_event_max_sample_rate to 50100
However, this seems to be a normal occurrence after playing games (https://bbs.archlinux.org/viewtopic.php?id=170471), so I would guess this is not related to the kernel panic.
For reference, here are some hardware specifications of my Dell XPS 13:

Hopefully this should be sufficient information, I've linked to this thread too. I've also mentioned I'm willing to beam one at someone from Amazon, with 2-day shipping to the USA the Pluggable branded adapter is just under NZD$40, which I can easily live with.
===========================================================================================================
USB3 gigabit ethernet adapters with the ASIX AX88179 chipset (LevelOne USB0401-V3, Plugable USB3-E1000, SIIG JU-NE0211-S1 and others) are experiencing kernel panics in usb_hcd_map_urb_for_dma since 3.12. The issue does not seem to directly correlate with low or high network activity, occurring seemingly at random. Some panics occurred less than 5 minutes from boot and tens of megabytes of network transfer, while on other occasions it would be stable for multiple days with tens to hundreds of gigabytes of line-rate throughput and several sleep/resume cycles.
Both my Sony Vaio Pro 13 and another user reporting this issue on the Arch forums [1] are Intel-based, my USB controller is an 8086:9c31 (Lynx Point LP), the other is reported as a C210/7 series (unknown PID). A third with a Haswell Dell XPS has attempted my workaround and reports similar success.
I have a mediocre quality photo of my laptop's screen from one of these panics [2], the call trace - which is similar but not identical between my machine and that of the other user reporting the issue - is as follows:
usb_hcd_map_urb_for_dma

local_bh_enable_ip

So far as I can tell, the driver is unaffected as late as 3.11.6, but problematic as of 3.12 (and still affected in 3.13-rc5). The history of drivers/net/usb/ax88179_178a.c for this time period yields this patch, which at least in my somewhat limited understanding appeared a likely candidate. I've reverted this on my system - against several linux-next builds from the last 3-4 weeks - and have had no issues with this network controller since.

USBNET: ax88179_178a: enable tso if usb host supports sg dma
This patch enables 'can_dma_sg' flag for ax88179_178a device
if the attached host controller supports building packet from
discontinuous buffers(DMA SG is possible), so TSO can be enabled
and skb fragment buffers can be passed to usb stack via urb->sg
directly.
With the patch, system CPU utilization decreased ~50% and throughput
increased by ~10% when doing iperf client test on one ARM A15 dual
core board.

Unfortunately I have not retained the built kernel from a broken 3.12 build, so the system information below reflects the patched linux-next kernel I am running currently.
I understand this may be a somewhat obscure piece of hardware, I am willing to assist by drop-shipping one to someone from Amazon (or local country equivalent if the price is not extortionate) should it be required.

Streaming media from wireless external hard drive and MBP to TV?
Hi everyone. I have a retina MBP and have recently bought a Sony Bravia smart tv with wireless. I have a time machine (the new one) with an external hard drive connected to it with all my media, photo, movies etc. My tv is connected to my wireless from the time machine and I'm wondering how do I stream media from my external hard drive to my tv? And how do I stream media from my MBP to my tv wirelessly? I can't seem to figure it out. Also mirroring my MBP desktop to my tv wirelessly, can it be done without an apple tv? Thanks in advance.
I had the same issue. It was due to the appalling performance of the USB connection to the disk, not any issue with the wireless connection itself. My iMac was within 7m of the router, on the same floor, with a clear line of sight and good reported connection speed. I have the latest late-2009 version of the AEBS running the 7.5 firmware. This has loads of performance problems (read these forums). I'm hoping that Apple will release the new firmware (7.51) for download soon and then the issue may be resolved.

Can I connect 2 sony bravia's, a sony home theatre, 2 macbooks, 2 ipads, 3 iphones and a dell laptop and stream media from my apple devices to my tv? I have a sony bravia 600 series and 700 series and a home theatre( sony 7100 series)
The only way to stream directly to your TV would be if it is an AirPlay-enabled device.
There are many AirPlay-enabled devices but I am not familiar with Sony's products. If yours do not specifically indicate AirPlay capability, then you need an AirPlay-enabled device such as an AppleTV connected to your Sony TV or Sony AVR. -
Comcast cable and streaming media
I just got Comcast cable access. Web browsing is super fast and email seems pretty smooth. BUT, I no longer can access internet radio thru iTunes, nor can I view or listen to any streaming media. BIG disappointment right off the bat. I've spoken to one Comcast support person who concluded it must be an Apple problem and told me to call them after checking out my connection and modem. I had Verizon DSL just 3 days before and everything worked beautifully.Network Utility returns a 100% failure when i ping a site most of the time, but then it works fine with 0% loss at other times. I'm going to contact Comcast again and talk to a different person.
Any thoughts??"BUT, I no longer can access internet radio thru iTunes, nor can I view or listen to any streaming media."
"I had Verizon DSL just 3 days before and everything worked beautifully."
Judging by the above, apparently some settings must have changed when you switched over to Comcast. Check your iTunes preference settings & the preference settings of whatever apps you use to view streaming media.
Another thing you can try is this;
Repair permissions.
Shut off your computer.
Disconnect the cable modem from the power outlet for approximately 3 minutes.
Reconnect the cable modem & turn on the computer.
If none of the above works then recontact Comcast. However, this time ask/demand/be firm to speak w/a tier level 2 or 3 mac tech support. Make sure you get a case#.
Explain the problem to the tech in detail.
The Techs may have you unplug your modem like I explained previously. If they ask you if you already did this always tell them NO.
Sometimes, they may ping your modem. Depends on the situation.
Let them know how long you have been "having problems". Give them a date & remind them again about giving you a case # if they did not give you one in the beginning of the troubleshooting efforts.
This is where your case # comes in. You do not pay for internet cable service that you never receive. Your case # is your only proof. The Tier Level Techs will provide further instructions. They are the only ones who provide case #s. (Very Important if dealing with Comcast - for your personal records, make a note of the date & time of the call, techs name & location. They will only give out their 1st names. This will come in handy if there is a discrepancy in your bill/you did not get your credit.)
Good Luck -
Versioning and parallel development streams for worldwide SAP roll-out
Hi SDN folks,
My customer is in the process of a worldwide roll-out of SAP. They have a transport environment for ECC that looks like this:
D -
> QA -
> R -
> P
We have SAP Charm installed and running in solution manager - to manage the creation of transports in the D system.
The problem we are facing is how to manage parallel development changes and configuration changes.
For example - if we have developers working on a change that is in test in the QA environment - and we hit a production emergency in P - we then need to make an emergency change to the P version (which would only be available in P and R) - and transport this change through to P - in the process - overwriting the changes that our developers are working on in the D and QA environments.
We also have the issue of objects for multiple countries being developed and configured in parallel - and so there will be version conflicts up the to the QA system as well.
Is there any kind of solution for the management of parallel development streams - and versioning - for all custom code / development objects and for configuration changes(other than introducing a second development system)?
Is there any kind of 3rd party product for SAP that helps to solve this issue?
Currently we are considering development freezes, manually renaming objects with versioning identifiers (will only work for some objects), manual backups of versions. - none of these seem to be a tidy universal solution, is there one?
Any help / directions you can offer will be appreciated,
many thanks,
JulianHi Julian,
Thanks for the clarification!
Managing production support and new development after go live is always a challenge. It can be addressed in many ways, but it is most important to create a set of rules and stick to the procedure. If you do not want a "second" landscape, you are going to have objects "overwritten" in the D and Q systems when you need to make a production fix -- as you must revert the object in D to the P version to make the fix. Even with a second landscape, objects will have to be merged somehow when a fix is promoted to production.
As I said above, what you can do is have your developers save their current development in released transports before making the production fix. This saves a version that must be merged with the fix, anyway. That is:
Object A is the produciton version and must be fixed.
Object A' is the current development version (unfinished) and is saved into a released transport request.
In D, Object A' is reverted to the A version and corrected for the production error, creating object A'' that is promoted to production.
Object A' and A'' are manually "merged" into A''' as the new current development version.
Yes, objects are overwritten with this method. However, you can always retrieve what has been overwritten since it has been saved in a released transport.
Another option is to bypass Q for production fixes. I.e. D -> R -> P. However, this invalidates the objects in Q until the merged version is created in D and transported to Q.
In any method you choose to do this -- dual development landscapes or not -- discipline and managment are a must.

flash player 11 is very glitchy on ALL browsers and makes my CPU usage 100%, making all youtube and pandora or any streaming media a headache, i have a low-end but good quality Emachine with Windows 7 Sv pk. 1, AMD Athalon Processor 2650e 1.6 GHz 2GB ram 32-bit, which isn't that bad, it used to play HD videos and everything without a skip or lag, it is virus clean, and clean of any large bulky programs, the only thing that went wrong was the fact that the adobe flash updates slowly but surely made it worse, AND it will not let me roll-back to an older version anymore like it used to, so WTF is up? no one seems to have an answer for this, and it seems like ADOBE is doing everything in it's power to not let me ask this question or get it solved, maybe it's because I AM TOO SMART FOR IT AND KNOW IT'S A FAILURE. so please, anyone who actually has a degree in this field is welcome, but no BS anymore, i want answers.
[moved to Flash Player forum]
Message was edited by: siniousThe jump to FP11 was pretty significant with Stage3D. Now Flash Player has a lower level access to your computers GPU to offload playing video and 3d rendering to the GPU. However if your systems GPU isn't up to the task you really won't see that performance gain.
Enter H264 video decoding. A large segment of the Flash usage market is simply viewing video. For sites without fallback in mind (or don't mind software rendering fallback), video may suffer. Using the GPU accelerated video classes may make it difficult for your system to view playback. Disabling hardware acceleration as recommended above would revert you back to software (CPU) decoding to check if your system itself is the issue (and not all the new GPU additions). You did that yet you're still having an issue.
Just to clarify, as I have an eMachine (for accounting), your computer is very much in the "budget" margin. You have a 3 year old single core 1.6ghz AM2 CPU with 512kb of L2. That's the K8 series. This is a very underpowered, single thread loving CPU. Only the most optimized Flash sites and lower end videos (720p or below) should play, but I'm not even sure if they'll "play well". It depends on your GPU.
Also you should know they have an official list of unsupported chipsets and drivers based on many factors. Here's a list for FP11 and AIR3:
http://helpx.adobe.com/x-productkb/multi/stage3d-unsupported-chipsets-drivers-flash.html
Check the bottom of the screen to see what Flash is reporting your rendering mode is. For example, mine states:
Your gpu supports Stage3D in both Baseline and Constrained profile!
Baseline RenderMode:
DirectX9
Constrained RenderMode:
DirectX9 (Baseline Constrained)
This probably won't get better in the future for you. Flash is not a low end multimedia runtime. It does require and utilize high end hardware in a much more reliable way. -
Hello,
I am a student and love the Visual Studio Community 2013 to implement some of my research projects. I am currently working on a project that involves streaming data analysis. I found this article ( http://azure.microsoft.com/en-us/documentation/articles/hdinsight-hadoop-storm-scpdotnet-csharp-develop-streaming-data-processing-application/
) but do not have MSDN subscription (I cannot afford it) as required in the article. Can this be done somehow with Visual Studio Community 2013 sign up?
Thank you all in advance for your time and for your help.
J.K.WHi,
I just confirmed that the key with Visual Studio Community is that, although it is free like Express, it does not have the limitations that Visual Studio Express had. So, to answer your question, Yes - you can do all your development work as a student with
VS Community 2013 sign up. You can also refer to this blog for more details -

Email and Printing would be nice
The two things (so far) that I find myself wishing Bridge would do is to let me print a file directly and to send something by email with a keyboard shortcut or a right-click menu. Two things that I do often.

Why is it that I suddenly can't open Bridge any more? Mac 10.6.8 and Bridge was fine until recently. Anybody able to help?
