Sophie MPEG Player

OK, I've pulled the MPEG player from Sophie. It looks worlds better. 

Ok, it's fairly impossible to rely on GStreamer on os-x. The problem is that you need to use MacPorts or something as root to

Hm. That's Squeak's player which was removed during 3.9/3.10 along with
some other cool stuff related to audio/video, because the classes were not
referenced... A tool doesn't have to be referenced by code IMHO). If you
get a 3.8 full image, it will have that.

Thanks - this is *so cool!*  Multimedia is important.  My secret wish is for a PdfMorph.

Chris, have you been using this successfully?  I imported a flash (.flv - H.264, 320 x 216, Millions; AAC, Stereo, 22.050 kHz) file into OpenSophie, but when I played it, the sound played for just a moment and the video only updated when I clicked pause or play.

Thanks.

Sure. Download Sophie-MPEG-Kernel and Sophie-MPEG-Player from the MultiMedia repo. Then

MPEGMoviePlayerMorph new openInWorld 

The buttons can guide you from there. Actually, I think I made a movie about this. But it is

MPEG only and such. If  you want an example of the QuickTime player download the example book
from the Sophie site about Macbeth. 

What you may want, I think, for Flash is in the OpenCobalt download. (http://www.opencobalt.org). It comes 

with an swf file called actin-myosin.swf, which is an animation. It plays fine in my Adobe Flash CS5. 

The problem I think you're having with it in Sophie is that you're trying to play a movie. Time was Flash

was for animations only. You may be trying to make it do something it can't. This stuff is old, dude.

(JMM gets kind of itchy about these conversations, because 
we're talking about ancient stuff. The vein of gold runs from SophieMovie. I'm digging that 

out, but asking me why I can't do it overnight is to ask my why I'm not an advanced programmer. 
March 2011 ETA for the Sophie Media Player in Squeak 4.2. There's only one person who can wake-up and know 

all these things without coffee - JMM. i.e. Morphic/Tweak Player, Process, QuickTime framework,
Carbon/Squeak event management, C, MCGetMovie, FFI, SophieMovieFramePlayer,SophieQuickTimeMovieViaPlugin, 
and the Surface Plugin. But I most certainly digress.)

Ah, yes. I remember the movie.  I'm trying to play a flash movie, so I don't know why I thought this would work (although if I get desperate, I could convert to mpeg first...)

Strange, now my .flv is playing correctly in OpenSophie!  But I can't figure out how to recreate what Sophie is doing from the UI in the API.  I tried:
        t _ SophieQuickTimeMovie new.
        uri _ URI fromString: 'file:///Users/sean/textmovie.mov'.
        t openMovieFromURI: uri.
        t play.

How do you open a Quicktime file programmatically?

Thanks.

How to open a QT movie programmatically?

What you added in the last message looks about as good as it gets. As
in, I don't know how, because I don't think that works.

SophieQuickTimeMovie class >> example example2 example3

has a simple solution to that question, which I can see you've found.
But it doesn't work. Running the Tests for Sophie shows some stuff is
broken.

I gave up trying to open a movie with code in a Workspace, and decided
to learn from what works, which is to open the Macbeth example file.
That shows a Tweak-managed infinite loop ( [self isMovieDone]
whileFalse: in SophieQuickTimeAudio>>playMovieScript) running between
SophieMovieFramePlayer and SophieQuickTimeMovieViaPlugin. The Player has
the buttons. ViaPlugin accesses QuickTime on the Mac.

I'm still in the middle of digging out details about Tweak and
#startScript: before I go back to that part. It's lead me down an
AsyncScriptMessageSend rabbit hole. If  you want to freak yourself out,
open the ProcessBrowser. Freaked me out.

I know nothing about Tweak.  How did you jump from seeing the Sophie UI to finding that loop?  When I couldn't bring up halos, I started fruitlessly searching brute-force through the class browser.

I'll check it out - I like excitement :)

"How did you jump from seeing the Sophie UI to finding that loop?"

You've put your finger on the big question in Tweak: how did this go
from here to there? Tweak teleports the flow of execution from one place
to another using method annotations. Stuff like <on: movieChanged> is
everywhere.

The simple way is to know that anything with <on: movieChanged> is going
to have a correlative method somewhere called #onMovieChanged:.

So, if I'm in SophieMovie>>updateMovie and I see signal: #movieUpdated,
I'm pretty sure there's going to be an #onMovieUpdated somewhere. Using
the MethodFinder, I find one in - you guessed it -
SophieMovieFramePlayer>>onMovieUpdated. It's a kind of convention.

Or you can use the Annotations browser from the menu with Monticello
Browser. I find knowing the convention more useful than the
AnnotationsBrowser, though.

When Teleplace asks questions of prospective employees "can you get up
to speed quickly with different UIs?" I think they are talking about
this Tweak transporter system that would be at home on the USS Enterprise.

I'm going to start a new thread since we're talking about QuickTime now...
