Hello, Well that is great news!!! Libvisual is still a quick changing ground and I'm planning to do lots of updates when I'm back home (I'm currently on vacation in greece (yeah it's great here!)). I lacked connectivity for a while, that is why there aren't many updates in CVS lately! About the particles xmms plugin port, I think looking at lv_gltest (the openGL analyzer xmms port) should help! I'll do a bigger update when I'm back home. Cheers, Dennis Smit _________________________________________________________________ Zoek niet langer. Vind. http://search.msn.be |

Hi, I managed to get libvisual working with amaroK a couple of weeks ago, but delayed writing to the list until I had GUI support integrated. This is now the case If anyone fancies trying out amaroK CVS, there are instructions at http://amarok.kde.org). Our plan is to make libvisual the default visualisation system for our player as soon as libvisual has become more stable. Thanks for the recent change removing the use of "private" as a variable name by the way :-) Much appreciated. I fancy converting the xmms plugin "particles" to libvisual, any tips?

Heya List, I'll be going on vacation for two weeks starting upcoming monday! I've been doing all kinds of libvisual related things at home, new plugins, new things in the core library etc etc! When I'm back from vacation I'll be merging it with CVS! I also bought the openGL blue and red book (reference, programming guide) so I hope to improve my GL knowledge from now on! I created a roadmap for libvisual and I will put this online when I'm back home as well! I hope you all enjoy your vacation and that when I'm back we can heat up the development again!!! Ooh, I also will be going to school again, starting 30 august! Rock on! :) Anyway, cheers and updates (in the form of code, not in the form of blah blah) will follow when I'm back home again!

Vitaly, The idea about plugin libraries rocks, I never thought about it like that, so it's great to implement this! I can't try the patch for another 3 weeks or so because I lack connectivity at home and I'm using the public computers in a library right now. However when I've got connectivity again I surely will help intergrate this! My vacation will start in 7 days or so, going to Greece. I hope your vacation rocks and you have a great time!

These will contain some plugin's requirements, like depth.
Probably placing function pointers here could be nice idea.

It will make possible to create one library for multiple plugins.
For example, morph plugins can be separated to a simplier ones by depth
or make actor plugins with common codebase but very different appearance,
or all-in-one :)
These not plugins anymore, they are plugin libraries! :)

OK, here's a first patch. Sorry, it's againts old cvs tree.
Sorry, it's a dirty patch.
But it works. At least it's capable to run two ported plugins --
alsa and lv_dna.
No morph stuff is ported, but it's easy to do:
1. s/VisMorphPlugin/VisPluginData/ in lv_plugin.h
2. fix lv_morph.[ch]
3. port plugin[s].
Looks like that's all for now. I'm going on vacation for a week or two
starting monday or so. I won't be available.
Anyway, everybody is welcome to try this patch, fix something ;) and
send a report!

Thanks,
Vitaly

Heya JC, How is goom going nowadays ? :) You've got a point in your issue and I can't think of any sensible solution that is an always win for the user. Ofcourse the libvisual xmms plugin will rock the world, especially when the Lv display library lands. Hopefully when xmms2 lands, libvisual can be used in their core or something like that, so it's intergrated.

Duilio, I think the previous email got completely lost. However if you have time please look into fixing this when you're back from the conference. I had CVS access in this weekend because I was at a friends place, right now I'm back home email from the library, where I obviously can't submit patches to CVS. After next week I'll be in Greece for two weeks, and after that I'll be having connectivity again! I hope you've got great fun at the conference! Updates from me: The G-Force port is rocking, there are some bugs in the old G-Force version itself regarding the script VM and some scripts which I'll have to look into but besides that it's doing good. While being at the friends place I copied xmms plugins on a CD so I have something to port at home, thus I'm porting Jakdaw right now, I will also port xmms bumpscope and xpyre.

Sorry about the last incomplete mail, I'm using a web interface to write this, because I'm on a conference now (until weekend). Like I was saying, this way you do not interfere with the libivisual_PRIMARY targets. However, probably other things will be needed to be adjusted for this to work. I can help on this when I come back from conference, next monday. Bye, Duilio. |

Hello, I hesitate to eventually drop xmms support from the goom package. I'm worried about users who will install goom, look into xmms visual plugins list and will not see "What A Goom!" in the list. Any idea about this ? JC |

Heya Vitaly, thanks for your reply!
Looks quite good, tho I've got some questions.
____
struct _VisPluginInfo {
uint32_t struct_size;
uint32_t api_version;
VisPluginType plugin_type;
const char *name;
const char *author;
const char *version;
const char *about;
const char *help;
/* VisPluginData* will be allocated by Libvisual.
* Plugin only needs to init priv, if necessary.
*/
int (*init)(VisPluginData*);
int (*cleanup)(VisPluginData*);
union {
struct {
int (*x)();
} actor;
struct {
int (*x)();
} input;
struct {
int (*x)();
} morph;
} preferences;
what are these preferences for ?
/*
// count defaults to 1
const VisPluginInfo *get_plugin_info(int *count)
{
const VisPluginInfo info[] = {
/ * blah-blah-blah * /
};
*count = sizeof(info)/sizeof(*info);
return info;
}
What is count for ?
Besides these questions, it looks good, if you can create a patch for this
and put
it on the list, it would be great!
Also, I've been VisMemizing most of libvisual yesterday and also added a new
tool
'lv-inspect' that gives all information about a plugin.
(A question regarding this, how can I build a tool that needs libvisual to
compile
but resides in the same buildtree and should be installed on make install ?)
Thanks and cheers,
Dennis

Not much, sorry.
Is it OK to do smth like this?
I also tried to eliminate repeating entries in a structs.
==============================
#ifndef VO_PLUGIN
#define VO_PLUGIN
typedef enum {
VISUAL_PLUGIN_TYPE_NULL,
VISUAL_PLUGIN_TYPE_ACTOR,
VISUAL_PLUGIN_TYPE_INPUT,
VISUAL_PLUGIN_TYPE_MORPH,
} VisPluginType;
typedef _VisPluginInfo VisPluginInfo;
typedef _VisPluginData VisPluginData;
typedef _VisPluginRef VisPluginRef;
struct _VisPluginRef {
char *file;
void *handle;
VisPluginType type;
VisPluginInfo *info;
int usecount;
};
struct _VisPluginData {
VisPluginRef *ref;
VisEventQueue eventqueue;
void *priv;
union { /* only pointers here! */
void *genericplugin;
VisActorPlugin *actorplugin;
VisInputPlugin *inputplugin;
VisMorphPlugin *morphplugin;
} plugin;
};
struct _VisPluginInfo {
uint32_t struct_size;
uint32_t api_version;
VisPluginType plugin_type;
const char *name;
const char *author;
const char *version;
const char *about;
const char *help;
/* VisPluginData* will be allocated by Libvisual.
* Plugin only needs to init priv, if necessary.
*/
int (*init)(VisPluginData*);
int (*cleanup)(VisPluginData*);
union {
struct {
int (*x)();
} actor;
struct {
int (*x)();
} input;
struct {
int (*x)();
} morph;
} preferences;
};
/*
// count defaults to 1
const VisPluginInfo *get_plugin_info(int *count)
{
const VisPluginInfo info[] = {
/ * blah-blah-blah * /
};
*count = sizeof(info)/sizeof(*info);
return info;
}
*/
#endif
========================
So, one library can provide more than only one plugin interface :)

Heya List, I've renamed 'private' to 'priv' everywhere in libvisual. I've done this so plugins and applications can be written in C++, this was needed for the G-Force plugin. Vitaly, how is the display lib stuff and the new plugin framework stuff going ?

Heya, I've magicly forgotten my gmail password.. So that explains the hotmail address. Anyway, Updates from my side: I've ported the G-Force unix port to libvisual. It's not yet completely done but it's rocking none the less. I can't commit it to CVS because of the obvious reason, so you people will have to wait a few weeks :(... I was wondering if there is any news on libvisual hacking ?

It's a lot > of work... afaiu rewritting plugins is also my task :) Yep it's a lot of work! :) I've done a plugin system rewrite before. In the first version all plugin types had a different loader but right now all the types are encapsulated in the LVPlugin. However ofcourse only the interface with libvisual needs to be rewritten in the plugins so it's a generalized rhythm of changing the plugin interfaces :) Anyway it's a lot of work none the less I've got to hurry, one hour to pack all my stuff ;) Cheers and thanks for all the support, will speak to you people soon!

Alright, I just had some disturbing news. I will be without any form of connectivity for a month. Starting in 14 hours from now. I can't do anything about it, so we need to discuss the roadmap for the upcoming month, and what I can do myself while being connectivity less. Sorry about the situation, I can't do anything about it :( I might be able to do a release at a friends place, but I can't read my email from anywhere else than here. Ofcourse I will read the list archives when I'm at a public internet place. Personally I plan to work on all the param stuff, port over the old winamp gforce unix port visual. And some other stuff.

(That is, if you people agree) That is, if you agree. That way we will do a super release for sure :) About the VisColor changes, would you mind to post patches on the list before submitting it to CVS ? So I can review it better ? Thanks a lot, Dennis |

Alright list. We will not be moving into the new house as planned. There is an old oil tank in the ground causing legal problems and it's going to be removed the month coming. However that will not change that we have to get out of the current house at friday, for this reason we will move to another house for just a month. Because off this I will lose connectivity for probably atleast a week but possibly over a month. Besides I'll be on vacation in Greece for 2 weeks, 3 weeks from now. All by all, I will be 'less responsive' upcoming time, and also I won't be hacking much. So if anyone has something to discuss so he can continue with his current work, please talk now :) Duilio if you feel like changing libvisual it's palette system to use VisColor, also please go ahead :) Make sure the current vispal morph thingy system keeps working tho :) Vitaly might be looking at the new (superior) plugin system and is working on the display library. Gustavo is rocking on the mplayer plugin and other issues! Thanks all you people for the support with libvisual, Without you I would probably already dropped libvisual as another death project because of lack of motivation :) Well, that was it for now. Thanks and cheers, Dennis |

How easy is it to transfer GLX without interupting it's context, drawing ?. For 2d blitting we can just copy over the old buffer, put it in the new display and go on with drawing. Cheers, Dennis |

Thanks for your questions :) I think it's better to "transfer" drawing to another window. This will be done by backend. In case of fullscreen, the new window should be created.
