Hi,
in the download from sourceforge the php_ext dir is missing
so I tried cvs
but :
PHP Warning: PHP Startup: Unable to load dynamic library

Re: [Ming-dev] ASM compile ?

[strk <st...@ke...>]

Fixed it... the AS_V6 condition was set at *every* token,
so immediately reset after entering the 'asm' condition.
Will now only reset if in INITIAL start condition.

Need some add some tests to avoid breaking this in the future.

The culprit seems to be a *force* into <AS_V6> mode, which
seems to override any <asm> context somehow.

Commenting out the line:

 if(SWF_versionNum >= 6) BEGIN(AS_V6);

in swf5compiler.flex makes asm {} blocks work (but then no AS_V6
syntax would be allowed - try/catch etc..)

Hints ?

[Ming-dev] ASM compile ?

[strk <st...@ke...>]

I see that Ming's ActionScript compiler contains some
support for 'ASM' syntax, but can't handle to use it.
Does anyone have experience with that ?

[Ming-dev] Bug in display_list.c SWFDisplayList_writeBlocks()

[Alex C. <ac...@no...>]

There's a bug in SWFDisplayList_writeBlocks() in displaylist.c which causes
objects after a non-embedded video stream to not be written out. The
problematic bit is

        /* for each videostream in movie add VideoFrame */
         if(character && ((SWFBlock)character)->type ==
SWF_DEFINEVIDEOSTREAM) {
             SWFBlock video =
SWFVideoStream_getVideoFrame((SWFVideoStream)character);
             
             if(!video)
                 break;
         
             /* well it isn't really clear why we need the place-block here
              * its not metioned in the flash-specs
              * but its not working without */
             if((item->flags & ITEM_NEW) == 0)
             {
                 frame =
SWFVideoStream_getFrameNumber((SWFVideoFrame)video);
                 placeVideo = newSWFPlaceObject2Block(item->depth);
                 SWFPlaceObject2Block_setRatio(placeVideo, frame);
                 SWFPlaceObject2Block_setMove(placeVideo);
                 SWFBlockList_addBlock(blocklist, (SWFBlock)placeVideo);
             }
                 
              
             SWFBlockList_addBlock(blocklist, video);
         }

What happens if you're using NetStream instead of including the video
directly is that SWFVideoStream_getVideoFrame() returns NULL, and the
consequent break stops anything after the video canvas getting added.

An easy fix is simply not breaking on NULL.

             if (NULL != video) // which it will be for streaming video
             {
                /* well it isn't really clear why we need the place-block
here
                * its not metioned in the flash-specs
                * but its not working without */
                if((item->flags & ITEM_NEW) == 0)
                {
                    frame =
SWFVideoStream_getFrameNumber((SWFVideoFrame)video);
                    placeVideo = newSWFPlaceObject2Block(item->depth);
                    SWFPlaceObject2Block_setRatio(placeVideo, frame);
                    SWFPlaceObject2Block_setMove(placeVideo);
                    SWFBlockList_addBlock(blocklist, (SWFBlock)placeVideo);
                }
              
                SWFBlockList_addBlock(blocklist, video);
             }

I presume a proper fix would involve figuring out whether the video stream
is embedded or not to know if NULL is an expected return value, but it's not
clear to me how to do that.

[Ming-dev] next release ?

[strk <st...@ke...>]

All, I've just fixed a bug in 'makeswf' failing to
correctly set frame count the '__shared_assets' movieclip,
which is used to store imported movies' symbols.

We're going to use this functionality (see -i flag of
makeswf in makeswf.1) in Gnash testing framework, so
it would be nice to have a release to point developers
and users to for making this work.

I know we still have lots of bugs, but maybe we might
release a beta3 for further testing...

BTW, it seems that the use of beta# prefix breaks the
install rule, in that 0.4.0 (final) will be considered
*older* then 0.4.0beta#, at least on my system, thus
libming.so.0 will point to 0.4.0beta# after 0.4.0 is
installed. This makes me think it would be better to
directly release a 0.4.1 package.

[Ming-dev] SWFdrawSizedGlyph missing in perl extension

[Ian B. <ian...@au...>]

Hi,

Disclaimer: This is my first post to the list, and my first couple of 
days with ming, using the perl extension.

and now that we've got past that...

I have been trying to draw a glyph, using drawGlyph, and found that the 
output was absolutely huge.. as big as the viewport I think. I was able 
to use setScale to reduce the entire thing, but I didn't really want to 
have everything else looking thin and sticky.

Searching the internet, I found the PHP extension also provides a 
drawSizedGlyph function, which allows an additional parameter, int size, 
however this function is not included in the perl extension.

I have (quite possibly kludged) this by adding the following to 
perl_ext/Shape.xs:

void
SWFShape_drawSizedGlyph(shape, font, c, size)
       SWF::Shape shape
       SWF::Font font
       int c
       int size
       CODE:
       SWFShape_drawSizedGlyph(shape,font, c, size);



I have absolutely no idea if that is completely correct, or if the 
function is deliberately missing, but it works, and does what I want.

Does the ming project provide cvs emails when new stuff is commited to

Hi Stuart and Wolfgang,

I'll take a look at the patch and make sure PHP 5.2 and php 6.0 are up to
date.

Wolfgang,
 	It looks like this change is already in the libming CVS.

 	In fact, this reminded me that I neglected to mention that I have
recently resynced the PHP extension in our tree w/ PHP5, plus added a patch
to allow the code to build for PHP4 also (to simplify building the Debian
packages from the same source). If anyone is still having problems w/ PHP,
please try the php_ext from current CVS.

 	I also filed a bug w/ PHP (http://bugs.php.net/bug.php?id=39429)
contains some updates.

[Ming-dev] patch for ming php5 binding

[<ham...@t-...>]

attached is a patch that never made it into php
It adds two features:
streamMP3 now returns the nr of frames of the mp3 file, instead of nothing
This can be used for script like below:
$frames = $m->streamMp3(fopen("$mp3path/$file.mp3", "r"));
while(--$frames >= 0)
        $m->nextFrame();
streamMP3 also takes an optional second parameter - the amount of music
to skip at the beginning

[Ming-dev] Anyone on OS X making universal binary libming?

[Alex C. <ac...@no...>]

Anyone out there have an XCode project or some other convenient way to make
a universal binary libming on an arbitrary architecture machine? Right now
I've grabbed the ming-0.3.0.tar.gz release and compiled it separately on PPC
and Intel machines then manually called lipo to produce a universal binary
.a, which is rather suboptimal workflow.

I'd take a stab at an XCode project myself, but I'm an old school Mac guy
who's pretty scared by makefiles at the best of times, and this bison/flex
stuff in the actioncompiler folder, I have no idea what I'd do with that.
