ds.jar

[symonjfox]

Hey guys, I always used PVAstrumento for my purposes.

Now I wanted to try DS.JAR. .. there's just a little promblem ...

how do I open it?

I tried doubleclick, but Winrar opens it and there are a lot of java files.
I readed the manual but it's all in German, and I don't understand anything.

Please help me.

I don't know anything about Java & co.

Hi!

Open Winrar, go to menu Options, Settings, Integration. And uncheck the "JAR" extension.

Then go here:
http://java.sun.com/j2se/1.4.1/download.html

And get the "Windows (all languages, including English)" version of the JRE (Java Runtime Environment).

Install it and you're done. Now you can double-click the ds.jar file and the program will run.

Cheers.

[symonjfox]

Finally :D :D

thanks a lot.

but why has it written in JAVA? Couldn't he use C or Visual Basic or other?

As soon as you try it you'll find out that it performs well, although it's written in Java. I think the source is not available, else someone could port it to a native application.

I was just reading this article in response to queries regarding ds.jar and why it was not written in another language.
Please consult the following link for an overview of Java.

http://java.sun.com/docs/overviews/java/java-overview-1.html

I will sumarise that a java script is processor architecture independent,and operating system independent. This fact is rarely mentioned and obviously requires a lot of hard work when new hardware and operating systems appear. As far as I know it costs nothing to aquire the tools to generate a script such as ds.jar.
I understand that ds.jar is the only choice for Linux users unless they emulate Windows with the Wine package and then use PVAStrumento. I have had mixed results with PVAStrumento so I prefer ds.jar as it gives me superior results given the local reception problems.

The program dialogue is in English however all the discussion forums are in German at this time. I rarely have problems though I would welcome some kind of German to English translation for the essential facts.;)

Java code commplies to bytecodes that are executed by a 'java virtual machine' or JVM, allowing you to write something once and have it run on any platform. No more waiting for someone to port your favourite app to mac/linux/solaris/etc.

Java also has extensive libraries built in, and has *huge* open source support for just about anything you might want to do. It also has cool features like garbage collection, checked exceptions etc, that make it quicker and less error prone to develop with.

It is largely a myth that java performance is bad, from earlier jvms that were mostly interpreted. The performance of java can be close to or even better than 'native' applications in some cases. This is because the bytecode can be dynamically optimised by the runtime environment during execution, taking into account the real usage patterns of the code.

Unfortunately I found a bug in Ds.jar (both 61 and 62).
I have a DVB stream that is broken somewhere. Well, for video, just dropping Gops, for audio it just demuxed the first 9 minutes and then stop.

Well, DS.JAR won't be developed no more, so it's useless my information.

never mind.

[stax76]

I wonder if somebody asked the author to release the source. I's a nice guy

[symonjfox]

Well ... once there were the sources avaiable for download, but they removed the link since nobody has to have it!
I think that major DVB companies will be hurt by DS.jar and PVAStrumento.

[leo_fischer]

If you are desperate, it is quite possible to de-compile the java bytecodes. if the code has not been obfuscated, it might be quite understandable.

[Leolo]

Hi,

I downloaded the source code when it was still available. I can upload it somewhere if you want it.

Just ask :)

Cheers.

[stax76]

would be great you could upload it

EDIT BY BARONVLAD:

Link removed, no warez sites please.

Ehm Dolemite, I think you should know the rules (Rule 6). :confused:

[Leolo]

OK. Sent to Upload center 1.

If there are any problems, drop me a note and I'll upload again.

Best regards.

[BaronVlad]

I am very sad that I have to repeat it. AFAIK Matthias does not want to provide the program and the sources so please dont discuss it in the forum !

If we can get a statement of Matthias, that allows us to provide something we will provide it.

This thread is still open to get a feedback by Dolemite (if he wants to add something), warez and links to dsjar and sources wont be tolerated, when I see some, I will close this thread and strikes will follow.

[stax76]

sorry about the link. I know Matthias but didn't have any contact for a very long time. He is a nice guy so I wonder what happened, did anybody ask why he discontinued ds.jar? Last time I chatted with him he planned to add cutting facilities to ds.jar

[BaronVlad]

Hi Dolemite,

it is a very sad situation since we all know the advantages of ds.jar., but AFAIK there was no official statement, why he does not continue the develeopment. So we could only guess.

I have "seen" Matthias some times in the boards (doom9.de mainly), he seems to be a nice guy.

I only know this (german) statement by Matthias at the support board: http://www.nv-systems.net/dvbforum/viewtopic.php?t=66

Dolemite, since you were in contact to Matthias, do you see any chance to get into contact with hin again to ask him about a download link and the sources so we can end this useless discussion. We all want the same in this thread, but I cant. :scared:

Thank you

;)

[Joe_Bloggs]

I agree that Matt is curtious and a man of his word. I have requested
that he should use the doom9 'umbrella' if things got to much for him.
I also suggested that an English translation of the instructions on
how to use DS.JAR would probably swamp his free time etc due to
queries from numerous directions. My term was 'a can of worms',I was
reading between the lines and was probably going cross-eyed at the
time. I think he can cope with his limited user base of German users.

http://www.nv-systems.net/dvbforum/ has never been open to
English posts. I have suggested to those who handle requests to doom9
that the translators of doom9.de should let us know what is
going on in their part of the world in this and other matters.

All the facts are in German, I wish I had payed more attention in Class.

[Joe_Bloggs]

In the event of no reply from the Author of DS.JAR I suggest that this forum be used to collate a specification for a replacement program. Perhaps the original author could contribute as well.
The replacement should be cross platform as it is basically bad file
in > good file out.
Tools like this will be increasingly important in the future as digital TV takes off. Unfortunately digital tv will be more prone to interference when it has to share bandwidth with conventional TV.
It probably has to use frequencies that are on the edge of terrestrial TV transmitter and recieving ariel groups. Its quality will also be down through detail limiting codecs etc to stay within narrow multiplex bandwiths etc. Some forms of multiplexing are prone to interference more than others.

In my view error minimising technology such as DS.JAR is essential.
A specification of what it did best is a starting point.

PS. I have killed two threads in a row regarding nforce motherboards
and where to find the best advice. I feel guilty. Somebody please reply even if it is SymonJFox and his lack of disk space.

[symonjfox]

Ah, sorry, I didn't updated my sign. Now my new disk arrived and works fine. New 60GB for record and test :)

Yes, you're right. Maybe the DVB providers don't want that we record and edit their programs, because there are many business under it. Let's imagine. You record many movies from DVB (from FTA and Encrypted channels), then you edit them and create you own DVD/MP4 (or whetever you want) disc. If you do it so, you'll never buy that DVD that you have recorded from DVB (that has similar and good quality). Don't you think so.

IMHO they insert some errors in the stream, that standalones will ignore, but software, like pvastrumento, will care and cut gop.

I noticed it while recording a famous movie from a scrambled channel (I've an original card for it). For example I started recording about 15 minutes earlier and stopped it 30 min after. Well, using PVAstrumento, there were few errors in the first 15 min, in the movie there were thousand of errors (bad frames and so) and at the end, few errors.
Obiously I had to delete it because there were too many cutted gops.

Back on thread.
DS.JAR 0.61 and 0.62 gave me the same error. I tried to use another recorded movie, well the video has been demuxed as well; the audio ... just the first 18 seconds :mad: why?

Maybe I'll reinstall ds.jar and strictly keep default settings.

symonjfox:

I highly doubt it, I don't think errors are intentional. I recorded hundreds of GB off the satellite and I had no significant/unrecoverable errors.

Maybe it's your card buggy software/drivers?

Also, I'd like to say that even on premium pay-tv channels, the movies are half the bitrate of a dvd movie.

[symonjfox]

Maybe it's your card buggy software/drivers?Yes it is :(
I've a Twin Han / Vision Plus 1030 wich is known to have bad drivers and bad quality of the software.
I use MyTheatre for recording from FTA and using that software I gain up to 50% quality of signal, while using WinDVB/WinDTV it's stick to 25-30% and FULL OF ERRORS.

What card have you? I'd like to change mine when I'll have some money to spend.

[DrP]

symonjfox I'd be seriously checking out the quality of the signal coming from your antenna with an error rate like that.

[symonjfox]

I have already checked.
I connected a standalone gold box at the same connector (instead of the TwinHan 1030) and it gave me nearly the max quality, no stuttering, no errors.

It's a known problem that my board has. I read on this forum (http://forums.dvbnetwork.com/index.php) and there are many many users that have the same problem. We have mailed to Twin Han asking to relase new drivers and new software, but no answer.

Here you can found the Java sources of DS.jar to take code to your own programs.

Seems that reading is sometimes very difficult:
