As the subject .
I can use the rawcapture code to see the display on monitor .
However ,there's still the fvid_exchange problem in preview on the fly .
I look up the memory of buffer ,and i don't see any change in the buffer.
In the rawcapture example ,i can see clear the datas are moved and changed .......
what happen to this code ???
I've tried for a long long time.....Is there BUG in the preview on the fly example ?????
HELP
THANKS.
This is the preview engine flow from the VPFE guide.
I find that at the beginning if the sensor raw input is send to CCDC ,the raw data should be 10 bits.
Is that correct ? Or it can be 8~16 bits per pixel ?
If the input has to be 10 bits ,the original configuration ( 8 bits ) in the preview on the fly sample is wrong ?
Strangely , the memory at 0x01c70458 is the FMTCFG
When I run the code ,it shows 0x00004000.
I look up the CCDC FMTCFG register ,the 15th bit should be 1 ,and the video port could be enable then.
It seems the video port are disable now......
BTW .the #define PSP_VEDIO_PATH_ENABLE is enable in this way ,right ?
Regard
ellen.
