I'm trying to change the size of the external OSD video (PIP) to be full screen.
But using Blimp on the eval board sample OSD project, I can't change the resolution at all.
When I open the project, navigate to the ExternalOSD element, and select it, I get these two errors:
Description: The type or namespace name 'UCHAR' could not be found
(are you missing a using directive or an assembly reference?)
Error 1 (same description and file, just different line/col):
Ignoring this error, I tried to change the resolution, default value was 480p.
No matter what value I put in this field, it doesn't "take". I tried 720p, which was an option,
and also various custom values, both larger and smaller than 480p. Nothing would be accepted except 480p.
Q: How can I change the resolution of the ExternalOSD element?
Eval Board: ADV8005
Blimp release: 3.8
Sample Project: /SampleProject/ADV800x/AVR_OSD_DEMO/ProjectFiles/
As a quick test, I made a blank project, accepted the default startup blank page, which I then set to be 1280 by 720.
Then, I was able to add an ExternalOSD element. It came into being with a default value of 480p, which I changed it to 720p with no problem. Interestingly, just to check what the error would be if I forced the ExternalOSD to be larger than the main page, I tried a custom resolution of 1281 by 721. It accepted this with no error message.
If I have to, I will run with my simple Blimp project of only one element, the External OSD. But in the interest of time, I was hoping to just tweak the sample project to minimize the learning curve during what is still an evaluation effort.
