Does the same apply for the DM6446?

DM355 VPFE doesn't have capability to blend text with video before capturing. It can only blend text/graphics with video using the OSD in the VPBE.

Your options are: - Put the text in the OSD buffer (/dev/fb/0) and it will be blended before output from VPBE - Draw the text onto the buffer in memory, using software - Add hardware to overlay the text before it goes into the VPFE. Just to note, the hardware (355 anyway) does not support blending OSD graphics before encoding video, if that is what you are trying to do. We have ended up using an external encoder chip to do this.

In the encode demo, each video frame is captured from /dev/video0 and then copied (using the hardware resizer) into /dev/fb/3. Simultaneously, dynamic data (e.g. CPU load) is written into the OSD window /dev/fb/0. The transparency is set through /dev/fb/2, which is opened as an attribute window. I would like to blend an OSD layer of text with my raw video before it is captured by the V4L2 driver. How can I do that?
