BassBox

[Patrice Terrier]

Here is a copy of a private message i got from Jordi Vallès, about the BassBox CPU usage reduction on his VISTA system.

I post it there because it could help other VISTA's user as well.

Today I implemented your sugestion to reduce the Bassbox CPU usage and playing with the value of ApiSleep and reducing the FPS to 42 the problem with of Bassbox on Windows Vista on my PC disapears. Now can see the beautiful screens without any problems, equal as my other PC with Windows XP. 

I sent you this good notice for your information.

By the way, there is another small code modification you could add to the RenderOpenGL subroutine if your CPU is very busy at the time BassBox starts runing:

SUB RenderOpenGL(BYVAL glCtrl AS LONG)

    IF IsWindowVisible(glCtrl) = 0 THEN EXIT SUB

    LOCAL graphics, nLevel, nLpeak, nRpeak, glDC, InDWMmode AS LONG
    LOCAL BBP AS BBPLUGIN
    LOCAL C1, C2, C3 AS LONG

[Emil Weiss]

Please can anybody tell me where i can found the Source of BassBox
has great Visualisation and think translate (Interface in/out) it do Delphi used in BassVis ( Visualisation wrapper for Bass Audio Library )
your help is welcome

sorry my english is not the best i hope you can understand me...

i hope the translation is not to hard

greets Emil

The source code is attached as a ZIP file to the first post of this thread.

Hi Emil,

usually you can find project files attached to the first post of a thread.
So go to the very first page of this long long thread and look at the bottom of the first post.

Patrice code merit a deep study.

Ciao
Eros



Patrice, 35 secs faster than me 

[Emil Weiss]

thanks 
i hope this is the right thread or should make new for this ?

i'm have load Archive BassBox_1_27.zip
think this is right..

This is how to perform further CPU usage reduction in BassBox.

Just cut and paste the code below into the BassBox source code as a replacement for the previous RenderOpenGL subroutine.

And here is s screen shot of the CPU usage on my VISTA computer while using the FLASH plugin:



The result gives an average FPS of 34, that is almost the same than for a movie.

The source code has been edited because left and right view meters were not redrawn anymore, this has been fixed, please cut and paste again in case you did it already.

[Emil Weiss]

i have replace it ..
has no effect by me can not compile BassBox with no PowerBasic

wait for you has update the Archive

thanks

greets Emil

[Patrice Terrier]

You can get the latest public version there (compiled)

...

[Jordi Vallès]

Hi Patrice.
After apply your new code to reduce the CPU usage I can see perfectly the BassBox in my PC with Vista. The FPS indicates 33.

Thanks.
Jordi

[Jordi Vallès]

Hi Patrice.
Using the lastest compiled code that have FPS 66, the old problem with Windows Vista on my PC appears again. Seems that the problem is directly related with the amount of FPS.

Regards
Jordi 

[Patrice Terrier]

Jordi,

Then this is clearly related to the power (or underpower) of the graphic card being used.
Anyway, 34 FPS would be quite sufficient, because it is almost the same than for playing a movie (see MovieBox).

Thank you for sharing your feedback.

...

[Emil Weiss]

Question..

Please can you make in the future when you have time
Change BBP.Title to PluginFile

and added new
BBP.Title for SongFile

then make a great SongFile Animation like Milkdrop or other that can show in the Visualization
when change the FileTitle ?

greets Emil

[Patrice Terrier]

The Phoenix

UnZip it in the BassBox BBPlugin folder, and enjoy.
