Hello, Everyone.

Now, I'm using EVMDM6437, PSP Driver 1.10 and DSP/BIOS 5.41.

I have just one question. In short, DM6437 can preview video images at 30fps through VPSS using PSP Driver?

I've just given video data to CCDC with a Image Sensor. And I've not used Any VPSS Submodule like Previewer, Resizer and H3A. Then, I got full charaged-buffers from VPFE using DMA with FVID_exchange() API. At the same time, I gave it(the charged buffers) to the VPBE using VENC and VID0(OSD).

That's all. 

But I can not get video images at 30fps. I just got 15fps with using the method described above. And I will have to get any information from this TI E2E community. But I could not find any useful information or data.

If you want, I can give you my full video_preview source(I got this source from DVSDK recevied by TI). If you could give me some advice, i will be very happy to you.

Thank you and Regards,

Zizek.
