Post - Processing Video Data From NetStream
Is it possible to intercept video data from a NetStream object and do some custom post-processing say 'deblocking on decoded data or decryption on encoded content' etc. The Sound class provides access to the SampleData but i havent been able to find the Video class providing similar support. Am i missing something or is this inherently impossible
Thanks in advance

I managed to perform video post-processing through alchemy some time ago. I think I drew the video to a BitmapData object, converted the pixels to a bytearray with getPixels() to read them, and then updated the contents with setPixels() straight from alchemy's memory bytearray every frame. Just watch out for endianness.
Really, I imagine video postprocessing would be better suited for a pixel bender filter than alchemy code, and in general it is definitely not something flash player is designed to do.

Problem while data processing TRANSACTION data from DSO to CUBE
Hi Guru's,
we are facing problem while data processing TRANSACTION data from DSO to CUBE. data packets processing very slowly and updating .Please help me regarding this.
Thanks and regards,
SridharHi,
I will suggest you to check a few places where you can see the status
1) SM37 job log (give BIrequest name) and it should give you the details about the request. If its active make sure that the job log is getting updated at frequent intervals.
2) SM66 get the job details (server name PID etc from SM37) and see in SM66 if the job is running or not. See if its accessing/updating some tables or is not doing anything at all.
If its running and if you are able to see it active in SM66 you can wait for some time to let it finish.
3) RSMO see what is available in details tab. It may be in update rules.
4) ST22 check if any short dump has occured.
You can also try SM50 / SM51 to see what is happening in the system level like reading/inserting tables etc.
If you feel its active and running you can verify by checking if the number of records has increased in the cube.
Thanks,

How to get/process the Data from XMLSocket?
Hello All,
I'm using Adobe Professional CS6, and Actionscript 3.0.
To start with I have a C# program that basically just feeds data out from a Server in the form of XML data. I then have a Flash program that should receive the data and then I'll do some stuff with it. We had this working in Actionscript 1.0 but we need to upgrade the code to Actionscript 3.0, but instead of just trying to convert stuff over to the new Actionscript version, I'm going to re-write the program.
So far I've basically just defined some EventListeners most of which I found examples of online for using XMLSockets. As of now the Flash program will connect an XMLSocket to the Server that is feeding out the data, and the server feeding the data resends new data every 5-10 seconds or so.
So when a grouping of XML Data comes in on the port I defined, the following Function gets executed for handling the incoming data. For my EventListener's Function for "socket.addEventListener(DataEvent.DATA, dataHandler);" ("socket" is defined as --> var socket = new XMLSocket(); ). So when the new data comes in it executes the above function.
The trouble I'm having is declaring a new variable of type "XML" and then using that variable to pull out individual "nodes/children" from the incoming XML Data. I found an example online that was very close to what I want to do except instead of using an XMLSocket to get data constantly streaming in they use the "URLLoader" function to get the XML data. I know I'm receiving the XML data onto the server because if I set the (e: DataEvent) variable defined in the function "head" to a string and then run a trace on that I can see ALL of the XML data in the "Output Window".
But I can't seem to be able to set (e: DataEvent) to a XML variable so I can access individual elements of the XML data. The example I found (which uses the URLLoader instead) uses this line (myXML = new XML(e.target.data);) to set the XML Variable, which won't work for mine, and if I try to do the same thing in my code it simply prints this for as many lines as there is XML data --> "[object XMLSocket]"
MY CODE:
*I left out the other Functions that are in my code for the EventListeners you'll see defined below, except for the one in question:
---> "function dataHandler(e: DataEvent):void"
import flash.events.IOErrorEvent;
import flash.events.ProgressEvent;
import flash.events.SecurityErrorEvent;
import flash.events.DataEvent;
var socket = new XMLSocket();
socket.addEventListener(Event.CONNECT, connectHandler);
socket.addEventListener(Event.CLOSE, closeHandler);
socket.addEventListener(DataEvent.DATA, dataHandler);
socket.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
socket.addEventListener(ProgressEvent.PROGRESS, progressHandler);
socket.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);
var success = socket.connect('server.domain.name.local',3004);
The code in this function was used from an example I found online as described above in the post:
LINK --> http://www.republicofcode.com/tutorials/flash/as3xml/
// The Commented out code (*in blue) will show ALL the xml data inside the "Output Window":
function dataHandler(e: DataEvent):void {
// var myStr:String = e.data;
var xml:XML;
xml = new XML(e.target.data); //<--- THIS DOESN"T WORK (I DONT THINK 'target' IS CORRECT HERE)??
if (socket.connected)
// trace(myStr)
trace(xml);
The Output from the line "trace(xml)" will show this data below in the "Output Window" (*FYI There should be 6 lines of XML Data on each 'update'):
[object XMLSocket]
[object XMLSocket]
[object XMLSocket]
[object XMLSocket]
[object XMLSocket]
[object XMLSocket]
Could someone show or point me in the right direction on this. I want to be able to access specific parts of the incoming XML Data.
Here's some sample XML Data:
<MESSAGE VAR="screen2Display" TEXT="CSQ_1" />
<MESSAGE VAR="F1_agentsReady" TEXT="111" />
<MESSAGE VAR="F1_unavailableAgents" TEXT="222" />
<MESSAGE VAR="F1_talkingAgents" TEXT="333" />
<MESSAGE VAR="F1_callsHandled" TEXT="444" />
<MESSAGE VAR="F1_ABDRate" TEXT="555" />
Any thoughts or suggestions would be greatly appreciated..!
FYI:
I'm VERY new to Actionscript/Flash Developing (*about a week now), so go easy on me haha...
Thanks in Advance,
MattHey Guys, thanks ALOT for the replies!!
Andrei1 and Sinious,
The code I show above is actually just what I found in an example online, and its what i was trying to show you what "they" used
in the URLLoader example. I wasn't trying to use URLLoader, but it was the closest example I found online to what I was trying to
do in terms of processing the XML Data, and not how I read it in. So XMLSocket IS definetly what I'm trying to use because the Server
I'm receiving the XML Data from "pushes" it out every 10 seconds or so. So yea I definatly want to use XMLSocket and not URLLoader...
Sorry for the confusion...
The example you show:
var xml:XML = new XML(e.data)
Is actually what I had in my original code but I couldn't get it to show anything in the "Output Window" using the trace() method on
it, so I assumed I wasn't doing it correctly...
What my original code was in the "dataHandler()" Function was this:
function dataHandler(e: DataEvent): void
var xml: XML = XML(e.data);
if (socket.connected)
trace(xml);
msgArea.htmlText += "*socket.connected = TRUE\n"
} else {
msgArea.htmlText += "*socket.connected = FALSE\n"
OUTPUT:
And what I get when I run a Debug on it is, in the "msgArea", which is just a simple Text Box w/ Dynamic Text on the main frame it prints:
"socket.connected = TRUE
socket.connected = TRUE
socket.connected = TRUE
socket.connected = TRUE
socket.connected = TRUE
socket.connected = TRUE"
It prints that message 6 times in the msgArea for each XML Message that comes in (*which I think 6 times because there
are 6 "sections/nodes" in the XML Data). But then NOTHING prints in the "Output Window" for the "trace(xml)" command.
Not sure why nothing is showing in the "Output Window", maybe the XML is not complete? But I could see data in the "Output
Window" when I set "e.data" to a string variable, so I know the Data is reaching the program. Since I could see the XML Data in
a string variable, does that mean I can rule out that the XML Data coming in is considered a "complete" XML Document?
Because I wasn't sure if to be considered a complete XML Document it would need to have this included in the message..?
"<?xml version="1.0"?>"
For the tests I'm running, one single XML message which is being pushed out from the server looks like this:
<MESSAGE VAR="screen2Display" TEXT="Call_Queue_1" />
<MESSAGE VAR="F1_agentsReady" TEXT="111" />
<MESSAGE VAR="F1_unavailableAgents" TEXT="222" />
<MESSAGE VAR="F1_talkingAgents" TEXT="333" />
<MESSAGE VAR="F1_callsHandled" TEXT="444" />
<MESSAGE VAR="F1_ABDRate" TEXT="555" />
Would I need to include that "Header" in the XML message above?
i.e. "<?xml version="1.0"?>"
Or do I need to be more specific in the trace command instead of just using "trace(xml)"?
Also yes, I already have a Flash Policy file setup and working correctly.
Anyway, thanks again guys for the replies, very much appreciated!!
Thanks Again,

FICA -IDOC for posting the billing data from NON-SAP ISU system
Hi,
Kindly note we are implementing NON-SAP ISU with SAP FICA for the finance implementation. In this context, we ahve identified BAPI for BP and CA. We have decided to go for transaction posting through the transaction FPE1. For this, we are looking for the transaction data IDOC which is CTRACDOCUMENT_ACCOUNT (FICA Posting) in the WEDI. But it seems that it is not yet released. Can anybody help me out for this to either identify the equivalent IDOC or other method to post the data from Banner system (NON-SAP ISU ) system. We are presently not implmenting billing system in SAP ISU, but only FI systemHi,
you can create the same...
but normal practice what we do is create swc for each system so that it is easy to maintain and easy to extend in the future..
or else follow some conventions if you are just starting the things..

Read Video data from buffer or byte array
Hi guys,
I've developed a tx/rx module, the tx read an mpg file and transfer it over network. rx has the data in a byte array, I also feed the byte array to a media buffer. Now my question is how to creat the player and feed the player to play the content of the buffer or byte array?
I would really appreaciate if someone could help me please...
Thanx
I haven't and didn't want to use any of the RTP stuff...Hi, I tried PullBufferDataSource. What I am trying to do is : read a .wav file into a queue, then construct a datasource with this queue. The processor will be contructed to process the datasource, and a datasink to sink data to a file. I think if this workflow could work, it should work in network transmission.
In fact the code works partially. The trick part is the read( Buffer ) method. If I try to use 'if' statement to see if Queue has empty or not, the datasink could not format the head part of output file correctly. If I didnot use 'if' statement, the program will terminate when exception occurs. The output file is all right.
I did not understand what is going on.
Note: the original file is a RAW data file without format info.
Here is the code fragments. Hopefully we can work together to figure it out.
Thanks.

How can I use Hash Table when processing the data from cdpos and cdhdr
Hello Guru,
I've a question,
I need to reduce the access time to both cdhdr and cdpos.
Because may be I'll get a huge number of entries.
It looks like that by processing cdhdr and cdpos data will take many secondes,
it depends on how many data you need to find.
Hints : Putting instructions inside a form will slow down the program?
Also, I just want use Hash table and I need to put a loop-instruction going on the hash-table in form.
I know that it's no possible but I can declare an index inside my customized hash table.
For example :
DO
READ TABLE FOR specific_hash_table WITH KEY TABLE oindex = d_oindex.
Process data
d_oindex += 1.
UNTIL d_oindex = c_max_lines + 1.
Doing this would actually not necessary improve the performance.
Because It looks like I'm having a standard table, may be there's a hash function, but it could be a bad function.
Also I need to use for example COUNT (*) to know how many lines I get with the select.
FORM find_cdpos_data_with_loop
TABLES

Post Business Partner data from SBL CRM to SAP CRM
Hi CRM Gurus,
I am very new to SAP CRM. I have got an assignment wherein I will get the XML file from Siebel CRM, which will contain the "Business Partner" data.
I need to upload this data into SAP CRM by mapping all the fields available in the XML file.
Please let me know the step by step process to reach the goal.
Regards
SandySandeep, since this is a conversion related task you might want to browse http://sap.help.com and search for the so called 'XIF Adapter'. This adapter is part of SAP CRM's Middleware and provides the functionality to import and export individual objects using XML/SOAP technology.
Second option you could evaluate is BP creation through the usage of the standard BADI's that SAP delivers. Let me know whether this gets you started, Tiest. -
I cannot access the video data from my canon vixia hf m500. is it because it is an HD file?
i have a canon vixia HF M500. I loaded the cds that came in the box, but i have a MAC, and they didnt really take, i think. I do have some canon software on here though, from a canonEOS Rebel t2i that does allow me to access files from that camera, pix and video.
the files from the vixia, however, are no accessible to me.
does the vixia have any MAC compatible software? or is there something i can do somehow to get my files? does the fact that the vixia is videoing in HiDef have anything to do with anything? are those files super large?
also, do movies in HD compress well for YouTube?
i hope youre having a great day and i send you hugs.
xo
madhagAH. am going to switch recording file to mp4, and i hear that should make the file MAC compatible.

Processing exported data from web application
Hi all,
here's my problem: I've got a Web Application designed in WAD and want to get the current navigation state (which is in the data provider) into an external application (i.e. a web service). What I already tried was to export the navigation state via SAP_BW_URL COMMAND='EXPORT' FORMAT='XML' and redireted it to a web service. But I wasn't able to get the XML document, I only got a XML_ID (as you can see in forum thread Accessing XML File).
Has anyone another approach to get the data exported and ready to be processed by a custom web service or external application (ABAP FM,..)?
Thanks in advance and best regards!
DominikDear Dominik,
maybe is XMLA for Analysis in BW a solution for you:
try this links
http://help.sap.com/saphelp_nw04/helpdata/en/ba/e380e03c3a4dbf8cf082f0c910f9cf/frameset.htm
http://help.sap.com/saphelp_nw04/helpdata/en/d8/3bfc3f8fc2c542e10000000a1550b0/content.htm
This a SOAP Web Service which gives back query content, the query is defined within MDX Statement in a XML file.
There also exists a detailed How To Document in SAP Service Marketplace - but unfortunately i can´t found it.

Oracle package to process multimedia data from BLOBs or so...
I have intention to make some toy/study application about search in multimedia data - so - for now my design is to put some pictures or even movies in BLOB fields and then extract/decode (e.g. I gues - maybe this can be done even in PL/SQL code) them as data for individual pixels and them try to process with usual methods that I descibed in scholarly journals or so... So - does there any package for such decoding already available? Open source or maybe - even as Oracle supplied package...
Hi, What decode type do you need ?? Do you use some special software for develop that??
Please let us know more information about your requirements,
Regards. -
Securely processing form data from applet
i have created an applet that will accept data. I now need the applet to open a data base file and put the data in the appropriate fields of the database. This must be done securely. Can someone point me in the right direction please.
doh, sorry ...here is the code. Everything compiles except this part
if(e.getSource() == frame1.panel2.submit)
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String url = "jdbc:odbc:MS Access 7.0 Database";
Connection con = DriverManager.getConnection(url, "Admin");
It tells me class and driver manager are not defined. What is it talking about. thnx. -
Fetch data from one table and insert into two tables in desired format
I have similar to the following data in a table and it is not normalized. The groupID is being used to group two records of similar nature.
DECLARE @OldDoc TABLE (oldDocID INT, groupID INT, deptID INT)
INSERT INTO @OldDoc (oldDocID, groupID) VALUES (1, NULL, 111),(2,NULL,111),(3,1,111),(4,NULL,333),(5,1,222),(6,NULL,333),(7,2,222),(8,2,333),(9,NULL,111),(10,3,222),(11,NULL,333),(12,3,444)
I need to process the data from the above table (@OldDoc) and write into two new tables (@NewDoc and @NewDocGroup) as follows.
oldDocID should be stored as newDocID when inserting to @NewDoc table. Only records with groupID NULL and one record (first one) per group should be considered (For example, oldDocID 5 is not considered as 3 and 5 belong to the same groupID 1) for insertion.
DECLARE @NewDoc TABLE (newDocID INT)
INSERT INTO @NewDoc (newDocID) VALUES (1),(2),(3),(4),(6),(7),(9),(10),(11)
All records from @OldDoc should be considered for insertion into @NewDocGroup table. OldDocID is inserted as NewDocID and deptID is as-is. Instead of groupID, the ID of the first record in the
group should be considered as parentNewDocID (For example, 3 is considered as parentNewDocID for newDocID 5 as 3 and 5 belong to the same groupID in @OldDoc table) for the newDocID.
DECLARE @NewDocGroup (newDocID INT, parentNewDocID INT, deptID INT)
INSERT INTO @NewDocGroup (newDocID, parentNewDocID, deptID) VALUES (1,1,111),(2,2,111),(3,3,111),(4,4,333),(5,3,222),(6,6,333),(7,7,222),(8,7,333),(9,9,111),(10,10,222),(11,11,333),(12,10,444)
How do I accomplish the above using SQL ? Thanks for the help.>> I have similar to the following data in a table and it is not normalized. The group_id is being used to group two records [sic] of similar nature. <<
Rows are not records. Tables have to have a key by definition. You do not do math with identifiers, so they should not be numeric. Let's ignore that error for now. In short, you are posting garbage. If you had followed Forum Netiquette, would you have posted
this?
CREATE TABLE Old_Documents
(old_doc_id INTEGER NOT NULL PRIMARY KEY,
group_id INTEGER,
dept_nbr INTEGER NOT NULL
REFERENCES Departments (dept_nbr));
INSERT INTO Old_Documents(old_doc_id, group_id, dept_nbr)
VALUES (1, NULL, 111),
(2, NULL, 111),
(3, 1, 111),
(4, NULL, 333),
(5, 1, 222),
(6, NULL, 333),
(7, 2, 222),
(8, 2, 333),
(9, NULL, 111),
(10, 3, 222),
(11, NULL, 333),
(12, 3, 444);
>> I need to process the data from the above table (Old_Documents) and write into two new tables (New_Documents and New_Documents_Groups) as follows. <<
Just like punch cards and mag tape data processing! Being old and being new are a status, not another kind of entity. But that is how mag tapes work. And you even use the verb "fetch" from tape files. This design flaw is called attribute splitting.
Do you have a Male_Personnel and Female_Personnel table? NO! It is just Personnel!
>> old_doc_id should be stored as new_doc_id when inserting to New_Documents table. Only records [sic] with group_id NULL and one record [sic] (first [sic; no ordering in a table] one) per group should be considered (For example, old_doc_id 5 is not considered
as 3 and 5 belong to the same group_id =1) for insertion. <<
Think about your punch card mindset. Why did you physically materialize that redundant New_Documents table? Let me answer that: this is how you work with punch cards! In SQL we use a VIEW:
CREATE VIEW New_Documents (new_doc_id)
AS
SELECT old_doc_id
FROM Old_Documents;
>> All records [sic] from Old_Documents should be considered for insertion into New_Documents_Groups table. The old_doc_id is inserted as new_doc_id and dept_nbr is as-is. Instead of group_id, the ID [sic: which identifier??] of the first [sic: tables
have no ordering like a deck of punch cards] record [sic] in the group should be considered as parent_new_doc_id (For example, 3 is considered as parent_new_doc_id for new_doc_id 5 as 3 and 5 belong to the same group_id in Old_Documents table) for the new_doc_id.
<<
Why not use 5 as the parent? My guess is that you are trying to form equivalence classes. See:

How to upload the data from excel(3 tabs) file to sap environment
Hi all,
This is Mahesh.
how to upload the data from excel(3 tabs) file to sap environment (internal tables) while doing bdc.Hi,
The FM 'ALSM_EXCEL_TO_INTERNAL_TABLE' makes it possible to load a worksheet into an internal table in ABAP.
However, if you want to get the data from several worksheets, I think you are stuck with OLE access to your Excel Workbook...
You can find a solution for 2 worksheets in this post :
TO UPLOAD DATA FROM 2 EXCEL SHEETS INTO TWO INTERNAL TABLES
I think you can easily modify it to handle any number of worksheets.
Hope it helps !
Best regards,
Guillaume
