Re: Is WMV possible in Rev

Mark is probably a more serious multimedia developer than I, but I've done a
lot with video and audio importand play in Rev in the past few months. My
view is almsot the same as his (and I, too, own Flip4Mac, a delightful
program that not only lets me play WMV files on OS X without using Windows
Media Player but also lets me save QT files in .WMV format, which for Web
delivery is a real godsend).

I think the best solution for cross-platform playback is definitely MP3. I
have not used .AVI primarily because I've found MP3 to be so useful.

However, there is one potential problem with MP3s and that is the one Mark
alludes to in his response. You really have to stick to very generic codecs
when you create your MP3 files or you will find yourself eitner saddled with
the responsibility of notifying your users what codec to get and how or with
unhappy users whose experience with your MP3s is not on a par with their
experience with "everyone else's" MP3s, making it, of course, your fault
that your sounds don't play well.

WIth QT, that's less a problem, and since Rev handles QT files seamlessly, I
tend to deliver my sound and video products to end users as a Rev app with
QT files stored as custom properties and bundled with the app. So far,
nobody has said they couldn't play those files on any platform and nobody
has yet complained about quality or anything else. So that's my first
solution when I'm delivering a Rev app. I use MP3s when I store sound on the
Web for download without benefit of a Rev application.

(There are other advantages to using Rev custom properties to store the
sound files. The user gets a single download, and you can avoid the
necessity of the user even having to know where the files are stored
because...in effect...they're not.)

Re: Is WMV possible in Rev

Thanks for the quick replies Mark and Dan.

I'll go by both of your recommendations and probably stick with the built in 
playback.  I'm on XP and Flip4Mac sounds like a great program.

I usually have a number of  video with narrations in my projects and when 
the user clicks on the more info video icons in the interface the wmv's come 
on full screen on the XP with no issues.

I've found avi's are just too darn big for an interactive CD.   Since newer 
projects will be for OS X and XP I might look further into your Flip4Mac 
option.

Cheers

Flip4Mac has been updated recently for compatibility with QT 7.0.4

But assuming that you already have a library of stuff in WMV files, 
how do we implement playback of WMV from within a Rev stack that will 
work for BOTH OS X and Windows? Is there a way where this can be 
done? This is assuming that there's a bunch of WMV files and it is 
not possible nor desirable to transcode them to some other format 
(losing quality in the process).

Yes - I love xor.

function EncodeOrDecode pString, pKey
  local tNewStr

  repeat for each char c in pString
    put numToChar((charToNum(c)) bitXor pKey) after tNewStr
  end repeat
  return tNewStr
end EncodeOrDecode

...and you can see if it works by

put EncodeOrDecode(EncodeOrDecode("somestring", 90),90) is "somestring"

Back in the Jurassic mists when I was first learning about assembly
language I fell in love with xor. It's still my favorite opcode.

"stamp" copy methods

I'm looking for an efficient way to do the following:
1) I have a collection of about 50 very small graphics (b&w).
2) I'd trap keystrokes to set the cursor to a miniature  
representation of one of the above graphics.
3) Subsequent clicking on a "canvas" would create and place a copy of  
the keystroke-chosen graphic at the clicked location.
4) The location of the graphic now placed in step 3 can be tweaked  
with mouse or arrow keys.
5) Creation of arcs (music slurs and ties)
6) Creation of music "beams" for 8th and 16th notes, etc.

I'm especially interested in suggestions for step 3, but all  
suggestions would be greatly appreciated.

I have received over the years dozens of requests for an OSX- 
compatible pen-and-paper style music notation program similar to an  
admittedly amateurish one I developed in Supercard many years ago.   
I'm sure I can do better this time around, and release it for OSX,  
Windows and UNIX as well!

thank you,
Kurt

Which is the best and easy-to-use database for RR

Hello,

I am doing a project.  I plan to use RR and a reliable database for the project. I have some questions:

1. What is the best, easy-to-use and easy-to-learn database for RR?

2. Where can I find tutorials about RR and database?

Thanks and best regards

Alex

Well, here are some options that might be considered "efficient": use
buttons (whose icons are set to a range of musical note images) or
antialiased graphics (only under Rev 2.7, and even then, the graphics might
be too small to render nicely).  Both of these two options would rely on one
complete set of note images that are referenced, as opposed to duplicated.
But depending on how many objects you have per "page" you might be able to
get away with using image objects as well.  At any rate, I would establish a
positioning grid such that note objects (whether they be buttons, graphics
or images) "snap to" positions on the staff.  I believe there are a few
snap-to grid examples in the mail archives.

I think the project is quite doable, but it will involve a fair amount of
numeric/positioning management.

I never thought of referencing the images, but it makes sense. Avoids  
duplication and bloat.

This would make the program easier to use, as long as it could be  
disabled (music notation is a quirky thing; sometimes what "should"  
look right doesn't).

Thanks for your help, Scott.
