Hi, I'm completely new to 4D workshop and building your own project type stuff. It is something I have just started as a hobby and have little experience in electronic circuitry and programming.
I am using the uOLED-128-G2 kit with the current drivers and PMMC installed, I have it connected using windows 8.1 on VMware Fusion on a macbook pro,
I am very happy with the screen so far and that it works straight out of the box and someone like me is able to use it with very limited knowledge, however my simple success has driven my desire to make it do more, but I fear I may have bitten off more than I can chew.
So far I have managed to draw objects like triangles, and used demo's like the gauge program. But I am having difficulty figuring out how to display my own video files.
I am using the ViSi environment in workshop and the steps I have taken are these.
After I start a new project I select the uOLED-128-G2 in landscape mode.
I then click on the comms tab and make sure that the screen is connected.
I then goto the widgets\system media tab and drag the media icon into the form1 image of my display module.
I have no problems using and displaying the SHORT1.WMV that is provided. But when I try to use my own video I get a window saying "Invalid Floating Point Operation" this is where I become stuck as I have no idea what this is or what I am supposed to do to resolve it. (Also if I try this twice workshop will hang and have to be force closed with task manager)
I have tried to use a video converter to make my video match the SHORT1.WMV properties such as, frame width = 320, frame height = 240, data rate = 960kbps, total bitrate = 1024kbps, and frame rate = 30fps. But still end up with the same problem.
The original video was downloaded from youtube in MP4 format that I converted to WMV. I also tried converting the MP4 and the converted WMV to match the properties of SHORT1.WMV with no success.
I am wondering if there is some kind of specific type of video or video limitations that exist and what the type of video I need to play back is?
Is there a tutorial for ViSi widget video playback something similar to the 'how to draw pixels and lines in ViSi' app note? I was unable to find a guide for video playback in the app notes downloads section.
I have come across this link in the forums but am not sure if it is relevant, however I noticed the use of graphics composer which I will fiddle about with tonight to see if it helps (http://forum.4dsystems.com.au/forum/...video-question).
This reply mentions that the screen being used is not a video player (http://forum.4dsystems.com.au/forum/...6019#post46019). I would be interested in knowing which 4dsystem product would be best for video playback in a tiny screen size.
Also I was wondering if there is a way to make things upside down quickly like some kind of function, method that would invert images that I drew such as the triangle so I would not have to type in two individual set of triangles co-ordinates?
Please forgive my lack of understanding of such topics, I have tried to explain all the steps I have taken and detail everything as best as I can and hope that it makes sense. I would really appreciate any help and advice that anyone is able to provide back.
Thanks.
