About xplayer source code
Hello everybody,
For there are many GPLed code is mixed in XPlayer, we should not submit
xplayer into ASF. The end users of bluesky system can download this
component from other website, not ASF. In fact, the other components of
bluesky can work properly without xplayer. Xplayer is only useful when the
users are watching recorded course ware. So, this method will work.

Again, why do want to move to LGPL and not ASL?

Better we make a clear description about the relationship of BlueSky and XPlayer somewhere on our website.

and according to Bernd ,the report about xplayer should be included ,but
xplayer has been decided not to be placed in apache but in
some other places as a optional component for some copyright problem ,in this situation ,
is it necessary for the xplayer being included in the report?

I know what GPL is, but I don't know what IGPL is (LGPL, maybe?). And
why doesn't that read ASL? Again, there will be no GPL'ed code in
Apache repositories. Please request in your report assistance from
Incubator if you feel that there are open questions about licensing
and intellectual property transferation to Apache.
I also find it worth reporting that this project currently has one
component named xplayer based on mplayer and FFmpeg, which are (L)GPL,
and are potentially patent encumbered and must be replaced some time.
Thanks,
Bernd

BlueSky has been on incubation for the first stage on apache community.
The Bluesky Project is an e-learning solution designed to balance education resources between well-developed cities and poor regions of China, that is, bringing qualified education resources to backward area students.
Infrastructure has been set up. Mailing lists for dev, commits and user, with official website, are operational.

We are checking our code by deleting or replacing the libs used which is against the ASL for upload.

after some bit of research I found that mplayer and FFmpeg projects
are actually very problematic to integrate with an Apache project.
Both trigger concerns because they potentially include patented
algorithms. See http://en.wikipedia.org/wiki/Mplayer , Legal Issues
section. This is very bad. This software is simply not distributable
in many countries. But I am sure there are other libraries out there
which are safe to use, for example Vorbis and Theora at
http://www.xiph.org/

Browse http://incubator.apache.org/guides/
Lots of indispensable info there for incubating projects.
Especíally follow links "Podling PMC" -> "Podling Status Reports"
"Podling" means "incubating project", so this is you! :-)

I think mplayer and other third parts from which our system derived

(http://wiki.apache.org/incubator/BlueSky), isn't it? And we shall
provide download links of the all related source code in BlueSky Dev
website (http://202.117.16.176/). Well, our team will have done this
work as soon as possible. I agree that we ought to search for a

Nobody is talking about doing it in a hurry. But you better start now
if it takes long.
You might as well think about replacing xplayer with a properly

Re: Re: Re: About xplayer source code

xplayer is advanced on basic of mplayer (GPL) by our team. mplayer code is
the core of xplayer and provide many primary functions for it, such as
audio/video playback, streaming multimedia transport protocols and AV
encode-decode (actually supported by FFmpeg ). xplayer just add the new
function of playing synchronized multiple multimedia objects into mplayer.
It is very hard to divide mplayer code from xplayer in a short period for
ASL (even if we done, xplayer is non-functional). So xplayer is a vital
issue that we need discuss in detail.
Is it obligatory to commit xplayer code into ASF repository at present?
xplayer is just one application software kit of Bluesky that includes three
independent system, real-class system (developed by c++), MERSMP and
xplayer.

Our xplayer is based on Mplayer, wich is licensed under GPL.
It is very hard to separate our code from mplayer's code. So, we don't want
to submit xplayer to ASF for license issue.

Origin mplayer code which our xplayer is based on is downloaded from
http://mplayerhq.hu/ years ago. The document of all the changes are not
available, because during time of developing xplayer, we considered only how
to make it work, and didn't consider the licensing issues. Perhaps, some
clues may be found in the source code of xplayer.

What do you mean by "re-coded"?
Did you take the source code and changed it, adopting it to your needs?
Where is the original code base you took?
Where is a documentation of all the changes you made?

Can you explain more detailed how this will work, please? This is the

technical discussions here!

Re: Re: Re: About xplayer source code

Dear all,
Our xplayer has synchronization work for the played media objects. This
function is not provided by other players. In fact, Bluesky can run without
xplayer. So, the users who want to watch course ware made by bluesky can
download xplayer from other website. I think.

XPlayer is based on mplayer. We didn't pay much attention to the license at that time so we directly re-coded part of mplayer and here comes the problem.
XPlayer is designed for playing the courseware made by BlueSky.The courseware consits of 3 multimedia files and shoule be played synchronizly.XPlayer can do this automaticly.So other similar players can do,maybe open the 3 files one by one.

I have some questions regarding xplayer:
1a. Where can I download Xplayer? Is it documented somewhere?
1b. Where can I download the source?
2. Can BlueSky run with other players than Xplayer? It would be bad if
it was coupled tightly with some third party.
