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.

Using JMF playing AMR RTP Stream

Hi,
I wondering if anyone can help me----I used an extend decoder to decode AMR stream in JMF, and after decoding, I got 13bit uniform PCM, seems like JMF don't support this 13 bit LPCM to play directly, so , I used G711 codec converting this LPCM to 8bit A Law (I also tried U law ) , but sound is not correct. I don't know if there's other way to play these 13 bit LPCM or converting them to A/U Law PCM then to play it in JMF?
Thanking in advance!
Your sincerely!

Hi,
I am crying for there's nobody who want to help me.

I upgraded some things and Quicktime stopped playing MPEG-2 movies (black screen)!

I upgraded some things and Quicktime stopped playing MPEG-2 movies (black screen)!
I need help, I was ending a project and now it just plays black!
I have quicktime X.
HELP! PLEASE!
thank you.

Quicktime was working fine, I am not sure what Quicktime it was. I upgraded Java, I am not sure if I upgraded Quicktime. After that all quicktime movies with "MPEG-2 Video, Linear PCM, Timecode" codecs started playing black with audio in the background. iMovie was not used. Thank you, I am beyond desperate and I am starting to think no one can help me with this.
Then I am not sure how your created the MPEG-2/PCM MOV files. Files not imported via the MPEG-2 Import codec would normall remain in their long GOP compression format which it not edit compatible in QT based video editors. Those that are imported via the codec to make them edit-compatible then need the codec for proper playback in QT based players/editors.
Since you now say that "Quicktime is working fine," am I to assume that it is After Effects that is playing "black" screen videos and that the files play fine in the QT players? Since you also mention the files are time coded, am I to assume you used FCP or some other app to import the files (which may use the same sort of import workflow) or am I to assume it is the timecode data itself that you feel is now causing the problem. In either case, a Java update may have been a security update that is now causing your current issue by disallowing access to the required playback component for some unknown reason which Apple is unlikely to divulge if it refers to a software security risk.
If problem is general on your system, then do you have a short sample file that you can upload for testing purposes on my Snow Leopard system? At the very least, this may confirm if the problem is general to all updated platforms or local to your individual system and/or user account.

Question - applet using JMF for playing .mov

I develop an applet using JMF for playing .mov. It works fine, and the applet starts normally. Even my applet works fine from other computers in our LAN (The applet runs ok without JMF). But only on one PC it doesn't work and I get the following message

I have some question on "Use LabVIEW to Control two DSP and RTDX"

I have some question when writing LabVIEW. I have DSP6711 and DSP6416, I use RTDX to send data to LabVIEW.
I write three programes for LabVIEW, one is RTDX for DSP6711, another is RTDX for DSP6416, and the final is RTDX for two DSPs.
The program of LabVIEW is workable when doing DSP6711 or doing DSP6416. But there is some problem when running DSP6711 and DSP6416 on LabVIEW at the same time.
How to tell the LabVIEW's tool of " RTDX read" to get the datas from different DSP

What you want to do should be fairly straightward and a good way to learn labview.
First off, if you haven't already, I would download the drivers for the Keithley and Agilent instruments. I found the keithley drivers at the link below. You will need to find the labview drivers for the Agilent PS at their website. Drivers are the VI's you will use in your program to control the insturments.
http://sine.ni.com/apps/we/niid_web_display.download_page?p_id_guid=E3B19B3E90B0659CE034080020E74861
If you open Labview and go to the help menu and click on Labview bookshelf there is alot of information on getting you started coding labview. This should get you started, if you have anymore questions just ask in this same thread and I am sure you will get all the help you need.

Question while using report /SAPAPO/SDORDER_DEL

Hello all,
While using Report /SAPAPO/SDORDER_DEL and going through system documentation, I found that:
"Normally, the order data remains in the database (it is not deleted as in live Cache)."
From the above statement I am assuming that data gets deleted in live cache on a timely basis, Can someone please let me know how frequently the data gets deleted in live cache?
Thanks for your time,
Venkat.

Hi Venkat,
There is no specific frequency for data getting deleted from the live cache.
It depend on the transactions which are taking place in R3 and APO.
For eg. Sales orders create a requirement in the R3 which is transferred to APO.
Now when this sales order is delivered, the requirements gets deleted from R3 and similarly from APO livecache. But this information does not get deleted from the APO database tables.
So this report is used to delete R3 document data that is no longer required in APO.
Cleaning of the database tables in APO leads to better performance.
So as a best practice, this report should be scheduled to run weekly.
Regards,
Asheesh Gupta

Error in native code while using JMF player

I have written the following test program:
import java.io.File;
import java.io.IOException;
import javax.media.Time;
import javax.media.Player;
import javax.media.Manager;
import javax.media.NoPlayerException;
class MyMP3Player {
public static void main(String [] args) {
try {
File mp3File = new File("test.mp3");
Player aPlayer = Manager.createPlayer(mp3File.toURL());
aPlayer.start(); // Starts asynchronous playback
Thread.sleep(10*1000); // Allow playback to continue for 10
aPlayer.stop(); // stops playback (well, it really PAUSES!!!)
aPlayer.deallocate();
aPlayer.close();
catch (IOException e) {e.printStackTrace();}
catch (NoPlayerException npe) {npe.printStackTrace();}
catch (InterruptedException ie) {ie.printStackTrace();}
It works fine for 2 times: I can hear the first 10 seconds of the test.mp3 file. Then, on the third run, after it has played the file for the 10 seconds, the program gives me the error pasted below and exits. Does anyone know how to fix this? Am I doing something wrong in the program? BTW, I am running WinXP.

Some questions about using non-english characters and keyboard layouts

I've found a lot of guides about how to enable characters in Linux, and that is easy enough, but I want to understand it better.
The way that I understand it, if you don't enable a given set of characters in locale.gen, then in theory you should not be able to either use or display a that set of characters in any programs (however, certain programs, like web-browsers seem to have work arounds).
Furthermore, in order to be able to type characters in X programs, you need to enable those keyboard setups in your xorg.conf (in addition to enabling those locales in locale.gen). I don't think that this effects the displaying of characters
Then, Last, you need a way to switch back and forth between different keyboard layouts within your X environment in order to type those characters. There are programs to assist in switching keyboard layouts provided by some DE's. By using these keyboard layout tools, I alter the behaviour of all programs started in X. (for example, swithing keyboard layouts in gnome's settings will alter the behaviour of kde programs, firefox and openoffice.)
How close am I?
A few more questions:
If I'm a Spanish student which locales do I need to enable. There is a long list of locales that start with ES, and I don't know if there are any drawbacks to enabling unnecessary locales. I think that the ones that I need are es_ES* (Spanish spanish?) and es_MX* (Mexican spanish?).
What is do the *@EURO locales do?
what does the locale setting in rc.conf do?

SOM Error while using Dynamic Tables

Hi Gurus,
    I have created a Adobe form with Dynamic tables and integrated in Webdynpro ABAP.
When I test the form, while opening the form the following error occurs ..
" The SOM Expression '$record.BP_DETAILS' for the dataRef specified on field 'BP_DETAILS' ,resolved to an incompatible node of type 'dataValue'..
After I press ok in the popup error message the Interactive form is displayed and I am able to add rows dynamically .. but the data .. but on submit the data is not passed to the context..
when i change the cardinality of the context from " 0..n" to "1..n" .. this error does not appear.. but while submit only the first row is saved to the context..
Has some one come across this error.. Please let me know how to get the dynamic table data to be passed to webdynpro ..
Thanks and Regards
Sivaraj

Hi
To show dynamic data in tables using adobe,follow these steps:
1. Create a value node say DataSource of cardinality 1.n and an other value node of cardinality 0.n which actually contains data.
2. create an array or use value node to collect data which is to be transferred to adobe.
3. data can be collected using for loop and create node element inside the loop and set corresponding values of each element.
4. add this element to value node.(step 3,4 are to be performed under loop)
5.You can use reverse loop to read and send data from adobe to data base which can be performed under submit button to sap.
Sample code to send data from dynpro view to adobe
Collection myRecords = new ArrayList();
myRecords.clear();
Collection records = new Vector();
IPrivateTestAdobeFormView.INotificationRecordsElement notifRecord = null;
int NUM_RECORDS = 5;
for (int i = 0; i < NUM_RECORDS; i++)
IPrivateTestAdobeFormView
     .INotificationRecordsElement
          notifRecordElement =
               wdContext
                    .createNotificationRecordsElement();
notifRecordElement.setNotificationNumber("" + i);
notifRecordElement.setNotificationDesc("Description for " + i);
myRecords.add(notifRecordElement);
wdContext.nodeNotificationRecords().bind(myRecords);
To save data from adobe to sap
IPublic<your view>.I<your>Node node = wdContext.<your>node();
        node.invalidate();
        int size = wdContext.nodeRFQ_Questions().size();
        Zqq_Qid_Ans_Txt newnode;
        for (int i = size-1; i >= 0; i--) {
             newnode = new Zqq_Qid_Ans_Txt();
             String answertext = wdContext.nodeRFQ_Questions().getRFQ_QuestionsElementAt(i).getAnswer_Text();
             newnode.setAnswer_Text(answertext);
             String questionid = wdContext.nodeRFQ_Questions().getRFQ_QuestionsElementAt(i).getQuestion_Id();
             newnode.setQuestion_Id(questionid);
             quote.addT_Qid_Anstxt(newnode);

Some question about using safari

I can't use the Safari to get into some school website ,such as ftp://10.10.192.163
How can i do that?

I suspect you have the url's (web addresses) wrong. I wouldn't think they would have a ftp: protocol designation but http: or https: instead. Generally ftp is used for retrieving data from a source not viewing web pages.
FWIW, I just tried those IPs with http: and https: and all I got was a spinning cursor (using Firefox). So either those IP addresses are wrong (but not wrong enough to error out) or the server associated with those IPs was down or hung at the time I tried it. I think (a) you need to verify those url's and (b) why are these url's using IP numbers and not some kind of pathname for DNS lookup?

Some questions about using dictionary6x.xls under Primavera 6.2.1

Now I used dictionary6x.xls (suppose it should support Primavera6.2.1 version), also i have install the SDK and access the DB (SqlServer) successful.
But When I use the dictionary6x.xls to retrieve or insert data, it will hit the exception, the log info as following:

I have searched for some advice for this situation, the result iis about update the "PMSDK.dll 6.00" version to "PMSDK.dll 6.2.1.1507" version.
I have double checked my local file "PMSDK.dll" version, it is 6.2.1.1507. But still hit this exception.
So anyone hit this issue before?

Delta question while using 'RSAX_BIW_GET_DATA_SIMPLE for delta datasource

Hello all,
we have created a custom datasource using FM and we have written it pretty much as a copy of this FM 'RSAX_BIW_GET_DATA_SIMPLE'.
we are using this extractor to extract data from one of the HR infotypes. Now how it works with infotypes is suppose you have one record for date 04/01/2011 to 12/31/999 and when you go in to create a new record it will delimit the previous one, so basically if you create a new record today the first record will go as 04/01/2011 to 07/31/2011 and new record will be 08/01/2011 to 12/31/9999.
Now how I am seeing the delat data comeover is I am getting the new record which is created with new dates of 08/01/2011 to 12/31/9999 but the extractor is not fetching the old/changed record of 04/01/2011 to 07/31/9999 so when i load data in DSO I have two records but both of them end on 12/31/999, I have Valid to as part of data fields in DSO so that it can be overwritten but since I am not getting/collecting the changed record the valid to is not changing.
Has any one faced this before and knows how to fix this?
Thanks in advance for your help.

Hi Cathy
Check the document for combining two date fields to get the timestamp.
http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/30aefb04-7043-2c10-8e92-941536eebc79
Now the two dates that you have to consider is the start date(08/01/2011) and the end date (12/31/2011). As per the document the record will be captured based on the change either in start date or end date or both. This way it should capture both records.

Problem while using read(char[]) method of stream

Hi I am trying to read different xml files, , hence i am using a buffered reader, and the read(char[]) method in the bufferereader.
//rawContent - is the xml file content
      BufferedReader br = new BufferedReader(new InputStreamReader(rawContent,
          ENCODING_FORMAT));
      int ascii = 0;
      char ch[]= new char[200];
      while((ascii = br.read(ch)) != -1) {
        rawContentBuffer.append(ch);
      }This is the error that i get when i execute the above piece of code. I have checked the files they have no white spaces after the xml contents.
Please tell me how i can overcome this.

Maybe it isn't. I don't know what 'rawContentBuffer' is, but you're assuming that 'ch' is always full when you call rawContentBuffer.append(ch). You need to call rawContentBuffer.append(ch,0,ascii) or some such form if there is one, or make some other arrangement for handling short reads.
