Hi,
I'm a newbie to swfmill, but I did get it working for my purposes... I'm
just trying to figure out how to make it more efficient. Here is my
situation:
Here's my inventory:
1. I have 1000 jpg images taken from a vga frame grabber - NOT in frames per
second... the timing is variable. For example, file1.jpg was grabbed at
30ms, file2.jpg was grabbed at 400ms, file3.jpg at 410ms, an so on. The time
starts from Time == 0ms when the frame grabber was turned on.
2. I have an XML file called capture.xml that contains the timestamp in
milliseconds for when each jpg was captured:
<Capture>
<FileName>Slide_0020.jpg</FileName>
<SlideNumber>20</SlideNumber>
<CaptureTime>64174</CaptureTime>
</Capture>
<Capture>
<FileName>Slide_0021.jpg</FileName>
<SlideNumber>21</SlideNumber>
<CaptureTime>64869</CaptureTime>
</Capture>
So....
By putting all the jpg files together into a SWF via swfmill, I should have
a fairly descent "flipbook" type animation. I've created a perl script to
parse the capture.xml file and creates a swfml file that looks like this:
<?xml version="1.0" encoding="iso-8859-1" ?>
<movie width="640" height="480" framerate="15">
<background color="#ffffff"/>
<frame>
<!-- frame:0 ptime:54 -->
<library>
<clip id="image1" import="Slide_0001_Full_resize.jpg" />
</library>
<place id="image1" name="myImage1" x="0" y="0" depth="1" />
</frame>
<frame/><frame/><frame/><frame/><frame/><frame/><frame>
<!-- frame:6 ptime:408 -->
<library>
<clip id="image2" import="Slide_0002_Full_resize.jpg" />
</library>
<place id="image2" name="myImage2" x="0" y="0" depth="2" />
</frame>
<frame/><frame/><frame/><frame/><frame/><frame>
<!-- frame:11 ptime:752 -->
<library>
<clip id="image3" import="Slide_0003_Full_resize.jpg" />
</library>
<place id="image3" name="myImage3" x="0" y="0" depth="3" />
</frame>
.....
Right now this is klunky because I'm trying to convert the millisecond
timestamp into frames per second. For example, if I want to run this
animation at 10fps, I know that the jpg captured at 100ms will appear in
frame 1 and so on (is that right??). So what happens in between each
frame... if file1.jpg is captures at 10seconds before file2.jpg, I just
stick (10x10) 100 <frame /> tags as filler in between the two images. There
must be a better way than this. Also, since I'm converting from
milliseconds to frames per second... I think I'm losing a lot of precision.
How could I create this "flipbook" effect, given the inventory above using
swfmill simple?
I think this is a pretty interesting problem and I really wanted to thank
the creators of swfmill... it's a great solution to this type of thing. I
was orginally trying to create an AVI file from this series of jpg files,
but it got way too complicated for me.
Looking forward to some suggestions!!
Seth
