Re: [shoes] trying to build Shoes on OS X 10.6.8 with video

Hmm. Has this kind of thing not been a problem for other similar
system libraries with respect to Shoes? I guess a start to addressing
it is to specify that certain versions of dependencies are required in
the Shoes install documentation per platform. Blerg.

In similarly uninspiring other news, I'm having trouble building VLC
without also building all the GUI components and many codecs which we
perhaps would not need at the onset. Some quick research in #videolan
on IRC suggests that there are Mac defaults which still kick-in
despite --disable-FEATURE flags, and this is just considered a known,
stupid bug that apparently nobody cares about. It was suggested I just
build the whole shebang because "it's easy." :\

I've got half a mind to just take the lib and include dirs distributed
with the VLC.app package and include them in the Shoes source, but it
seems that is not the path of Shoes these days.

I'm not sure at this point if I want to keep fighting VLC, or find an
alternative means of creating my little video player app I want for
myself.

Cue sad trombone.

You could put it into Shoes, like the sqlite code but then Shoes developers
have to maintain and track VLC bugs and chose the codecs to support cross
platform - big ick.

There were licensing issues with ffmpeg codecs for GNU/OSS diehards. Ubuntu
for example doesn't install most codecs - you have to specifically ask and
install the 'non-free' codec package. Another mess for Shoes to emulate and
support.

Green Shoes would be the best way to avoid the mess except I don't think
ashbb gotten to the video stuff yet.

Hrmm. OK. Thanks for the info.

Hi Cecil, Seth, Steve and folks,

> I don't think ashbb gotten to the video stuff yet.
hahaha. Yes.
But yesterday I found this: http://code.google.com/p/ossbuild

I have thought that GStreamer doesn't work on Windows. xx-P

So, after some googling, I found this:

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/chapter-helloworld.html#section-helloworld

Just now, I could compile helloworld.c and it worked on my Windows 7.
I could hear a song from a .ogg file!

The gstreamer gem for Windows is not released so far.
But if OSSBuild is useful for me, GStreamer may be one of the alternatives
for Green Shoes.

hey folks,

  i've built Shoes with GStreamer, and it works nicely on my ubuntu
system...

  i've been trying to get GStreamer to install on a WinXP system, but with
no luck so far...

  how did you get GStreamer successfully installed on Windows?  i can't seem
to do it...

   if we can get GStreamer to install and run on Windows (should be no
problem for Linux and Mac) i think it would be a good option for Shoes video
and audio - the API is pretty straightforward, and it sounds good ;)

Hi J,

Awesome!
But sorry, my English ability is very poor.
I don't understand the meaning of "built Shoes with GStreamer" clearly...

I guess that you've written Green Shoes app with Ruby/GStreamer gem.
Right?
If so, I'd like to see the code. Could you upload to gist or somewhere?

> how did you get GStreamer successfully installed on Windows?
As I mentioned in the previous post, The Ruby/GStreamer gem is not released
so far. But we can get GStreamer binary files for Windows (.dll files) from
http://code.google.com/p/ossbuild

I've just installed GStreamer-WinBuilds-LGPL-x86.msi and
GStreamer-WinBuilds-SDK-LGPL-x86.msi and compiled a C sample code
(helloworld.c). ;-)

Yeah, I totally agree.
I don't know Ruby/GStreamer gem for Windows will be published soon.
But we will be able to write some code to use the GStreamer dll files in
Ruby.
I need to study more, of course though. :-P

  no, i built a version of Red Shoes that includes the GStreamer gem and its
dependencies (so that you can "require 'gst'",) in order to re-write this
audio player - https://github.com/lljk/rubyWax - in Shoes...

  here's a link to a post that explains better what i did -

http://librelist.com/browser//shoes/2011/5/9/shoes-and-gems-with-native-dependencies/

  i've got a RedShoes(+GStreamer) version of the player more or less working
- i'll put it up on github once i fix a couple of bugs...

  i did finally manage to install gtk2 1.0 - and i've been able to play
around some with Green Shoes.  i like it a lot - but it seems like some
methods that i need for my player (most notably #rotate, which moves the
record player's arm) are missing...  or maybe i just don't understand how
the Green Shoes and gtk2 methods work together?

  i've installed the same on a WinXP virtual box, and it seems to have
installed with no problems.  i realize now that the problem is that the ruby
gstreamer gem won't install on windows...  oh well... :(

I don't know Ruby/GStreamer gem for Windows will be published soon.

  that would be great!  wish i could help - but i think that's a bit beyond
me!

  i'm investigating some ruby audio libraries, trying to find one that would
work well cross-platform with Shoes - once i get things sorted out a little
better i'll post some ideas...  we need media capabilities in Shoes!!

Oh, I remember now!

Are you looking for this?
http://ashbb.github.com/green_shoes/Art.html#rotate
But to move a record player's arm on Green Shoes, I recommed using show/hide
methods.
The sample44.rb may help you.

BTW, I have a good news. ;-)
Kou (Kouhei Sutou), an active Ruby/GNOME2 developer, built the following for
me.

- http://pub.cozmixng.org/~kou/archives/glib2-1.0.3-x86-mingw32.gem
- http://pub.cozmixng.org/~kou/archives/gstreamer-1.0.3-x86-mingw32.gem

 *Note*: The above glib2 gem is the same name as the gem published on
RubyGems.org.
         But it's revised a little bit. So, just overwrite an existing file.

This is just a trial. We know some problems.
But I think we will be able to use Ruby/GStreamer gem for Windows not so
far,... hopefully. ;-)

  hmm...  somehow didn't see that!  i was checking methods with #methods -
and not looking in the manual like a normal person! :P

  i'll fool around with it more - thanks!

  AWESOME!  i'll give them a shot in my WinXP virtual box and let you know
what happens!


  thanks again for the tips / updates!
