Streaming requires two files per video?
A client is requesting QT MP4 videos for streaming on a Mac server. He is telling me each movie must have two files, a short file to start paying back quickly and a separate file for the rest of the movie, so it can load while the first clip is playing. He can't give me any more explaination than this.
Can anybody explain this to me? I have never heard of it.
G5 Dual 2.0, 1.5 GB ram, 2TB RAID Mac OS X (10.4.3) FCP5 Suite, CineWave, blah, blah ...
He says true streaming through a QuickTime Streaming Server.
But the file I gave him for a test is a 1 min QT file, hinted for streaming. It takes about 10 seconds to come up on his site over my 3mbs connection. It looks to me like it is downloading.
He says this is because streaming requires two files and I haven't given him two files, a start file and the rest of the movie.
I have never heard of this "two files" thing. Have you? Isn't hinted for streaming always embeded?

Flash streaming external flv files
I have a web page which contains a flash object embeded in
it, this flash is streaming external flv files. The flash was being
displayed correctly when the website was hosted on a windows 2000
server but when the site was moved to a windows 2003 server the
flash is no longer displayed, instead of it a box with undefined
text inside it. I searched the Adobe support center and found this
Tech Note about adding the MIME Type through IIS since windows 2003
doesn't stream flv files. I followed the steps mentioned but still
am getting the undefined box
http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_19439&sliceId=2
Does anyone know how to solve this issue?
Thanks in advance.This is the problem.
When Flash Player movie files that stream external FLV files
(Flash videos) are placed on a Microsoft Windows 2003 server and
then viewed in a browser, the SWF file plays correctly, but the FLV
video does not stream. These files work correctly if tested on
other operating systems. The issue affects all FLV files played via
Windows 2003 server
And can be solved by....
1. On the Windows 2003 server, open the Internet Information
Services Manager.
2. Expand the Local Computer Server.
3. Right-click the local computer server and select
Properties.
4. Select the MIME Types tab.
5. Click New and enter the following information:
* Associated Extension box: .FLV
* MIME Type box:flv-application/octet-stream
6. Click OK.
7. Restart the World Wide Web Publishing service. -
We are trying to close caption our telecasts. We get the captioning files done out of house, pull them back into Premiere, and then embed them. The TV station requires .mxf files with the file embedded as a 708 stream, to play on their Grass Valley K2 video servers. We have tried multiple scenarios and cannot get the captions to display.
Whenever I export, it becomes a 608 stream, and will not play on their servers.Hello there,
I'm sorry to hear you are having a problem. Thank you for taking the time to post here.
Here are some questions:
1. What version of PPRO are you using? MAC or WIN?
2. Is the caption data you are embedding a 708 caption stream?
3. When you re-import the MXF with captioning embedded back into PPRO, does it show 708 closed captions in PPRO?
PPRO will embed 708 caption streams to MXF -- I just did this, re-imported the embedded MXF to PPRO, and I see the captions in the MXF.
If you could share one of your files with me, I could take a look.
Take care and thanks again,

Can't Stream File using Video object
I'm trying to get my video files to stream from my local version of flash media server to my instance of a flex application. I'm able to connect to the server and I'm receiving the NetConnection.Connect.Success code from the server. When I debug the application, I'm finding that I'm getting NetStatusEvent objects with the codes: NetStream.Play.Reset and NetStream.Play.Start. And the info object's details property is "sample.flv" which is the video file that I have sitting in my "FMSTesting" applicaiton folder. So my video is in my application folder at: "rtmp://localhost/FMSTesting/sample.flv", and my Flex application outputs to the webroot of the flash media server "http://localhost/FMSTesting/bin-debug/FMSTesting.html"
So I'm not sure if my setup is wrong or not, but I think it's ok because I can connect to the server just fine. I just can't get my stream to play on the Video object. Here's my code, please help if you can. I also attached the code

</mx:Application>Hi,
Your code is perfectly fine except for one statement.
ns.play(
"sample.flv");
Since you want to play vod, give the stream name without extension like - ns.play("sample");
But why you got NetStream.Play.Reset and NetStream.Play.Start events? It is because you have not mentioned the 'start' and 'length' values in your ns.play() method. Which takes the default for 'start' as -2, which means that Flash Player first tries to play the live stream specified in stream_name. If a live stream of that name is not found, Flash Player plays the recorded stream specified in stream_name. If neither a live nor a recorded stream is found, Flash Player opens a live stream named stream_name, even though no one is publishing on it. When someone does begin publishing on that stream, Flash Player begins playing it. Since you have mentioned the stream name with extension, FMS considers it as a stream which is not found in the server and started waiting for a live stream with the name 'sample.flv'.
Best practice is always give the 'start' and 'length' of the stream when calling NetStream.play() method.

My client requirements in File Adapter
Can any one guide me for the following requirements.
Case Studies - 1
Assume that you are in a class room and there are 10 students in it. The instructor then asks each student to prepare his/her the following personal details and save them in an XML file. The details are as follows:
Student ID
Name
Mobile
Email
Gender
There will be 10 files and the files are named as cv_1,2,3….10. The files are saved into the source directory. For test purposes following directories are created:
Source directory: c:\ibm\sap\training\input
Archive directory: c:\ibm\sap\training\archive
Error directory: c:\ibm\sap\training\error
Target directory: c:\ibm\sap\training\target
You are asked to develop scenarios in SAP PI which will read the source files from the source directory and write them to the target directory. Once a file is successfully read from the source directory, it should be moved to the archive directory and if the file cannot be read for some error i.e. xml format not maintained, it should be moved to the error directory. The files moved to archive, error or target directory should have a time-stamp append to the file-name.
i.e. filename+<time-stamp>.
Lesson-1
Prepare a scenario to read one single file i.e. file cv_1.xml from the source directory and write it to the target directory. The target file name should also be cv_1.xml with the time-stamp append to the name.
Lesson-2
Prepare a scenario to read all the files from the source directory and write them to the target directory. Similarly the target files should also be named as cv_1, 2 ..xml with the time-stamp append to each of them.
Lesson-3
The instructor then asks you all to add the following validation to the data.
The mobile-number should have 10 numeric digits – if the mobile number is not of 10 digit then replace it with ‘error’
The email should have one ‘@’ character and one ‘.’ character – if the email is not having the ‘@’ or ‘.’ character, then replace it with ‘error’
Before you run the scenario, in some of the source files, modify the mobile and the email so that they are in error as per the logic given above.
Lesson-4
Prepare a scenario to read all the source files and classify them according to their gender. The files for the men will be written in one directory and for the ladies to another directory. Two directories are created for the above purpose:
Target directory for men: c:\ibm\sap\training\target\men
Target directory for women: c:\ibm\sap\training\target\women
Suppose there are 6 men and 4 women in the class, then if all the source files are read successfully then the target directory for men should have 6 files and the target directory for women should have 4 files.
Case Studies - 2
The instructor then asks you all to prepare one single file with the personal details of each student in separate segments.
Lesson-5
Write a scenario which will read this file and produces 10 target files where each file should correspond to the personal data of each employee. The target files should be named as cv_<emp_ID>_<timestamp>
Lesson-6
Modify the above scenario so that it produces 2 target files instead of 10 where one target file for men and another target file for the ladies. The target file for men should have 6 segments for 6 men and the target file for ladies should have 4 segments for 4 women.
The target files should be named as
For men – men_<time-stamp>
For Ladies – women_<time_stamp>
Case Study -3
Same as case study – 1, the instructor ask each student to prepare his/her the personal details and save them in an XML file. There will be 10 files. The files are saved in the source directory.
Lesson-7
Prepare a scenario to read all the source files from the source directory and to create one single file in the target directory. The name of the target file will be output.xml with the time stamp append to the file-name. The target file will have all the details of each source file as sub-segment.
Lesson-8
Prepare a scenario to read the entire source files from the source directory and create two files in the target directory – one for the men and the other for the ladies. For 6 men, the men file should have six segments having each man’s details and for 4 women, similarly there should be 4 segments with each lady’s details.
Case Study - 4
The instructor now asks each of the students to prepare another set of details which will consist of his/her the following academic details:
Student ID
School Name
College Name
Department Name
Admission Year
There will be 10 files and the files are named as ad_1, 2, 3….10. The files are saved into the source directory. So each student will now have a pair of files – one for the personal details and the other for the academic details. Two files are co-related with the Student ID. The input directory now consists of 10 personal files and 10 academic files.
Lesson - 9
You are asked to develop a scenario which will pick the source files and will process them in pair. The scenario will generate 10 target files. Each target file will consist of the personal and academic details of a student in separate segments. The target files will be named as res_1, 2, 10.
The target files will look like:
Lesson – 10
You are then asked to change the student ID in some of the files so that they do not have a matching academic or personal files and vice-versa. The scenario should run and if it found any files who does not have a matching corresponding file then the process should end after some period of time i.e. 2 min and those files will be moved to the error directory and there will be no corresponding target files for them.Hi
These are the exercise mentioned in the blog
http://scn.sap.com/docs/DOC-41766
In SCN , you will find many blogs on file adapter. Go through them, you will be able to do it by yourself.

How to merge/append two files in sequence using BPM
Hi All,
My senario is to append two files data into a new file on target system, only if the two files are available on source system. In case one file on the source system, no need to process file. Data in the new file should be in sequence means 1st file data then 2nd file data.
Please suggest me how can i achieve this functionality using BPM.
Thanks & Regards
SreeniFor the first part (two files required) design as per Prateek's suggestion
Data in the new file should be in sequence means 1st file data then 2nd file data.
create a data structure which will be a combined structure of File1 and File2....target structure should have first reference for File1 and then for FIle2....than having two MTs (File1 and File2) at the source and the target MT at the receiver create your mapping......this will ensure that File1 data occures first and then File2 data.

Export DV Steam (.dv file) for Video Server Problem
From Final Cut, I need to export a DV Stream file for our Video Server. It accepts .dv files. Problem is: the exported clip "inherits" just over 5 minutes of black or the last frame of video on the tail. This creates obvious timing problems for our on-air playback.
I've seen other posts on this forum with identical problems, but none of them were solved. It was however suggest to NOT use DV Stream file. Unfortunately this is not an option for my station, as our server requires those files.
So in summary, exporting a 30 sec spot to a DV Stream becomes a 5 minute 37 sec spot. No good.
Thanks in advance,
TOR
Mac Pro Mac OS X (10.4.8) 8 GB RAMSounds weird enough! What servers are you using, and will they not accept a MPEG-2 transport stream as well? Most I've seen do and that can save a tremendous amount of space.
But back to your problem of the added 5 minutes of black; as I understand your description, you're saying that the extra 5 minutes is added at the tail end ... correct? If so, won't the programming aspect of your set up switch to another stream at the programmed time regardless if the first program is still playing? ie; you enter the start and end time of each event for playback. Say event 105 starts at 8:00:00 PM and ends at 8:00:30 PM. Event 106 starts at 8:00:30 and ends at 8:01:00. Each spot is programmed to air for 30 seconds so at 30 seconds into event 105, event 106 SHOULD start playback and be switched to air - even though event 105 still has 5 minutes of black to go.

Buffer Issue with streaming 10 MB file
Hi there,
Having a bit of a nightmare, essentially I have this code:
private void streamBinaryData(String urlstr,String format,HttpServletResponse response)
String ErrorStr = null;
try{
if(urlstr==null)
urlstr = "c:\\video\\hoff.flv";
File f = new File(urlstr);
response.setContentType("video/x-flv");
response.setHeader ("Content-Disposition", "filename=\"hoff.flv\"");
Long fileSize = Long.valueOf(f.length());
response.setContentLength(fileSize.intValue());
InputStream in = new FileInputStream(f);
ServletOutputStream outs = response.getOutputStream();
int bit = 0;
System.out.println("VIDEO STREAMER: start streaming data");
while ((bit) != -1) {
bit = in.read();
outs.write(bit);
in.close();
System.out.println("STREAMER: Finished streaming data");
outs.flush();
outs.close();
catch(Exception e){
System.out.println("DEBUG: "+ e.toString());
}which works just fine, but as the server that will be using this code essentially just (90%) will be the use of this servlet to stream .flv files I want to make it more productive by buffering all or some of the file in order to stream.
so essentially I have tried many times and variations around the following sub code:
InputStream in = new FileInputStream(f);
ServletOutputStream outs = response.getOutputStream();
int bit = 0;
System.out.println("VIDEO STREAMER: start streaming data");
byte buffer = new byte[fileSize.intValue()];
outs.write(buffer);
in.close();
System.out.println("STREAMER: Finished streaming data");The above pump about 1MB of a 10MB fine, but the hangs and no exception is received, or:
InputStream in = new FileInputStream(f);
ServletOutputStream outs = response.getOutputStream();
System.out.println("VIDEO STREAMER: start streaming data");
byte buffer = new byte[fileSize.intValue()];
for(int i=0; i<buffer.length; i++) {
outs.write(buffer);
outs.write(buffer);
in.close();
System.out.println("STREAMER: Finished streaming data");
which will pump out around 2-6 MB of the file, with both of the code changes above I can see the file being pumped at a much faster rate, but obviously no good as it does not deliver the whole file.
I know that content length is fine, I have also tried varying the response.setBuffer(int) to larger than 8192 up to fileSize.intValue to allow a buffer to handle the whole file before outputing, all to no avail.
I have also increased the runtime RAM via '-Xmx64m'.
I am developing on a windows tomcat (with netbeans) and the production version is unix based.
Any help that anyone can offer will be greatly appreciated.Thanks for the reply.
Hi, yes sorry has missed that (typed the other 2 variations by hand), I have tried buffering part of the file & tried using a BufferedOutputStream.
Neither worked either.
so for example, I used (done before, but hell tried again anyway):
InputStream in = new FileInputStream(f);
ServletOutputStream outs = response.getOutputStream();
System.out.println("VIDEO STREAMER: start streaming data");
BufferedOutputStream bout = new BufferedOutputStream(outs);
byte [] buffer = new byte[1024];
int length=0;
while( (length = in.read(buffer,0,buffer.length)) > 0) {
bout.write(buffer,0,length);
}this actually does worse as I only receive around 500KB.
Checked the link you provided, useful but the implemented solution is still reading 1 byte at a time, hense far too many reads going on for when the server will be (hopefully) sending out a few files per min..
essentially it seems like the outputstream (whether raw or bufferedOutputStream) is having issues with pumping data that quickly to it !???!?!?
or it's not liking raw bytes and only really working with the bout.write(int) method, the best solution so far has been this use when I mentioned above that I would receive between 4-6 odd MB of the file, this was nice and fast, just never complete. -
How to process two files at the same time using BPM
Hi experts,
I have a Integration Process it takes two files one Header xml and one Lines xml. These files shoudl be processed at the same time because them will be mappend in a Idoc.
The realy trouble is that these inbound xmls never are executed at the same time. Then a IP is executed for each inbound xml.
This is the IP:

I try to do all what I know, but It don't work fine :S
Thanks in advance and Regards,
Jose Antonio.Hi Jose,
Don't specify any end condition for fork step and check the start process check box in both the receive step.
Also put all steps inside the block.. so that the control step in deadline branch can throw exception and after that the BPM ends. As per the design now, if a deadline exception is raised (it will b handled) but after that the transformation step and send step is executed. There the BPM fails.

Dynamic Configuration for two file adapters communication channels
Hello Experts!!!!!!
In one of the interface in my landscape, I am using two file adapters for creating two files with different names and at two different destination on F.T.P.
However the receiver service for both the communication channel are same.
In message mapping I am using multi mapping to create two files out a single message.
Now i have a requirement of changing file path and file name using dynamic configuration for both the comm channel.
When i doing dynamic coniguration for both the comm. channel. My interface is creating two files but with same name and on same destination which is set for second communication channel through dynamic configuration.
Here, I guess the second dynamic configuration is over writing the first dynamic configuration and hence creating two files with same name and at same destination.
Please suggest, if separate dynamic configuration for separate communication channel of same receiver service can be done?
Thanks & Regards,
AmolThanks for your prompt responses!!!!!
Is there any way, By which in dynamic configuration I can find out the communication channel name and then change its parameter.
I mean if iam using say comm. channel A and B.
Then in dynamic configuration for A, I will first take communication channel A by calling it and then change its path/file name.
and then do samething for comm. channel B in its dynamic conf.
Regards,

Need to setup Premiere CS6 sequence for two file types with different field orders
I have a client who has shot video for me using two cameras, one camera was set to progressive, and the other to interlaced upper field first. I need to use both file types in the edit and have been struggling to set up the sequence to get the best look for the end product, a DVD. I have several videos to do for her that were all shot in the same way, so I need a solution!
I would appreciate help figuring out how to set up this work flow from beginning to end.
Should I convert one of the files from the beginning so they match field orders before going into a sequence? Or do I just need to do some adjusting of the files once they are in the sequence? Is it just as simple as changing the transcode settings to favor the upper field first? I'm definitely having issues once the video is transcoded in Encore and you can see a lot of jagged edges and lines especially during movement. My client isn't happy and I've tried several workarounds, but to no avail.
Here are the two file types I have:
File extension: .MOV
H.264, 1920x1080, Linear PCM, 16 bit little-endian signed integer, 48000 Hz, stereo
FPS 29.97
No Fields: Progressive Scan
File extension: .MTS (my Mac finder can't read these files, but they are read in Premiere)
Image Size: 1920 x 1080
Frame Rate: 29.97
Source Audio Format: 48000 Hz - compressed - 6 channels
Pixel Aspect Ratio: 1.0
Upper Field First
I am using Adobe Premiere CS 6.0.2
Encore 6.0.1
Media Encoder 6.0.2.81
I am running it on an iMac 27-inch, Mid 2011
with Mac OS X Lion 10.7.5
Processor 3.4 GHz Intel Core i7
Graphics AMD Radeon HD 6970M 1024 MB
I've just been setting the sequence to match the .MOV files since they look much better than the .MTS files. I've done the opposite as well, setting the sequence to match the .MTS files and it doesn't seem to help. I've also changed the field order of the files once they are in the sequence by changing the field options and have tried converting the .MTS files in the Media Encoder, but nothing I've done has worked.
Any help would be so appreciated! The client I have is a photographer, so she wasn't aware of this issue when she first shot these videos. So I have 10 videos with these issues I need to get back to her, hopefully issue free! I'm struggling as an editor because my last job I was using FCP and was working with videographers who knew what they were doing, so I've never faced such problems before. Plus I'm new to the Adobe software. Not a good combination. Please forgive me if I didn't give all the information you need. I will happily respond with whatever more information you may need to help me out!
~KTrouperI wonder if you could do your edit ignoring any visual issues of the interlaced footage but keeping the different sources separate ( checkerboard edit Vid 1/ Vid 2 )
Lock it down then export the interlaced part of the edit as a Digital Intermediate.
Maybe Export the other source as well to the same codec. DI
Bring them back together in a New Sequence. You wold have to deal with the black spacing. -
Streaming AVCHD MTS files to Apple TV
I am still in search of the holy grail I think... I have yet to be able to figure out how to easily grab my MTS files from my Mac and stream them *as is* without transcoding, converting, etc on my TV. I just bought new Apple TV not for that purpose but can't seem to find anywhere here if I can use it to to stream AVCHD MTS files to my HDTV. Does anyone know? thanks
I just bought new Apple TV not for that purpose but can't seem to find anywhere here if I can use it to to stream AVCHD MTS files to my HDTV. Does anyone know?
I hate to point out the obvious, but the normal practice is for the user to purchase the device that supports what he wants to do and not buy a device and the try to force it to do something it was not designed to do.
To begin with, QT does not support Transport Streams such as TS/MTS/M2TS at all and only supports muxed MPEG-2 Program Streams employing specific audio formats... and then not natively. In other words, your file containers are not compatible with the QT player built into the TV/TV2 device. And, even if you place the data in a supported container, the audio and video data may or may not be compatible with the player codecs embedded in the device firmware.
If your primary purpose is to stream content muxed in an MPEG/MPG/MTS/M2TS wrapper, it might be more prudent to purchase a device designed specifically for such content. For instance, I gave my wife, brother-in-law, and son TV2 devices for Christmas. However, my father-in-law insisted on a device the would play the videos from his camcorder and indicated that at 87 years of age, he had no intention of transcoding anything. As a result, I got him the LaCinema Mini HD device. While I cannot confirm that your files would be compatible with this particular device, it or something similar may meet your needs.
Basically, you have three options here:
1) You can convert your content to make it compatible with the TV device,
2 You can "hack" the TV device and modify its capabilities, or
3) You can buy a device that actually does what you originally want it to do. -
What is required to use the video composite out on the iPhone 4 The left and right audio works ok
Please not that the iPhone uses mono channel for internal speakers, the other path that you see is not the speaker per say. It is the phone microphone. Try using headphones, you will hear both channels. If the problem still persists when using headphones, check your sound balancing in the settings. Go to setting-general-accessibility scroll down and check the slide under mono audio. It should be put at the centre for you to hear both channels ON YOUR HEADPHONES
