I have a project that uses quite a few opencv libs to do some image processing tasks. Now I need to build a Flash app for it. I read that Alchemy allows compiling c++ libs for FlashI wonder if anyone has tried to build flash apps using opencv libs and dlls

While Alchemy supports compiling C++, it seems that using the using the STL is trouble, mostly due to a problem with std::string. What's strange is that Alchemy seems to be using GNU libstd++ v3.4.6. It's hard to believe that std::string is broken in GNU's STL.

I'm trying to use AS3_Shim in my alchemy code but it doesn't seem to be working.It always returns a NULL function pointer. There don't seem to be any examples of AS3_Shim's use, so I'm not sure what I'm doing wrong.Here is some example code:
static AS3_Val thunk_logtest(void *self, AS3_Val args) {
warning: this leaks
AS3_Val ns= AS3_String("mx.logging");[code]..........
i have a variable declared in alchemy asm:
asm("var buffer:Vector.<Number> = new Vector.<Number>(100, true);");
i can populate it with data like so:
asm("buffer[%0] = %1;" : : "r"(index) : "r"(value));
what i can't figure out is how to get a reference of that asm "buffer" variable into actionscript.
(i did think of one way... what i did was to throw the "buffer" from alchemy asm, and then catch it in actionscript, but unfortunately it seems to leak a lot of memory).
is there a better alternative to doing this?
note that performance is critical, and using default alchemy marshaling is way too slow.
I have C++ application that use OpenGL. Need to convert this app to flash app. Is it possible to do this with Adobe Alchemy? Is it will be possible to get from that swc current image (for example, with glDrawPixels) and print it on screen
View 2 RepliesI wanted to make live drums play with keyboard shortcuts. The problem was that MP3 is not good enough in this case (encoders adds random silence at beginning of the sound) and also flash itself makes delay (I tried use already buffered file with play specified_start_point_in_miliseconds)). So my solution is OGG (this format is gapless). I use compiled swc file from Adobe Alchemy library and simple frontend for it. Everything works fine, OGG file is playing, but its still much delay - no matter if its lodeaded external or as embedded, and if its first or n time. How to make sound play fast equally to key press.
Here is my very simple example code:
import flash.display.Sprite;
import flash.events.*;
import flash.utils.ByteArray;
import flash.events.SampleDataEvent;
import com.mauft.OggLibrary.OggStream;
import com.mauft.OggLibrary.OggEmbed;

I have seen a few blog entries on this and have had a discussion or two with my team mates but I would like to see what the stack overflow community thinks.
So why does the Adobe Alchemy Tool create so much faster running flash byte code than the flex compiler?
Also, when will the flex compiler be able to make similar performance gains? Will it require programmer specific use of special Array's or something of that nature to get the same performance?
Alchemy allows users to compile C and C++ code that is targeted to run on the open source ActionScript Virtual Machine (AVM2).

I am using Flex's Alchemy library to generate SWC's out of C files. I have a byte array (unsigned char buffer[size]) in the c-layer that I'd like to return to the ActionScript layer as a ByteArray. Do I have to iterate through the array and explicitly call AS3_Set on each element or is there a way to just return the entire C array at once?
View 2 RepliesI'm trying to use Adobe's OggVorbis library. But I can't seem to get the Sound object to loop. I even tried looping the _sound object inside the AudioDecoder.as in the "com.automatastudios.audio.audiodecoder" package. Do you really have to reload the file and stream it over and over?

View 2 RepliesIm calling a function in lua from actionscript using callstack : Array =

I am trying to send a bytearray extracted from a file to the C code and return that bytearray again from the C code..I am printing the contents of the return value from C in a text view contents.text but all i can see is the byte array object "OggS".

When I use pthread_create function create a thread in the c code, it fails.
But, the pthread.h in the avm2-lib directory is declared pthread_* functions.
I want to know whether the 'Alchemy' support thread.
I've got a simple question. Suppose some simple lib written on c. Did I understood correctly that alchemy compiles it AS3 before compiling it to swf. If so, will the lib be slower or faster in comparison with the same lib written on AS3.

View 3 RepliesAre there any programs or features in flash that can simplify flash vector art?
I just realized that one of the reasons why my program might be running so slow is that I made the images out of lots and lots of circles. When things didn't look right I often just put larger circles over smaller ones. I didn't think that flash might still be drawing the invisible circles underneath-

We've got a green screened video playing in a flash movie over top of our html content.when the movie ends, flash uses external interface .api to call a javascript function which swaps the flash movie out with a 5 x 5 pixel flash movie (rewrites the <div>).this works and you can interact with the html content after the flash movie in all browsers except firefox.anyone know of any work-arounds or is there a better way of handling flash over html in this fashion?
