Hi all,
Before I start with the actual thread I need to introduce my project. I am working on a video output plugin for the VDR. As hardware for the video output plugin I use an MPEG2 decoder card. Now to show the OSD I need to create a valid subpicture data stream. This works quite well, but I am hitting a limit in the CHG_COLCON Command.
The CHG_COLCON command uses PX_CTLI, which defines the start line and the end line, but also the number of LN_CTLI to follow. And we can follow max 15 of them. A LN_CTLI defines the new color indexes and alpha values to use at the given column.
So now the question is, what ways exist to eliminate this limit? Can i write more then one CHG_COLCON command blocks to get a valid result?
thanks,
ac
