Simple MJPEG decoding (800x480 @ 25fps)
This example also contains module for working with SD memory card and FATFS library.
The vid directory and its contents must be copied to the root directory of the memory card.

Thank Ozelot. Do you have the document about this feature? For example: Allwinner user manual...?

This project is based on CEDRUS sources.
JPEG decoding is fast. YUV2RGB converting in the first sources is slow (~60mS), so in the mjpeg demo I did a table conversion (~24mS).

Was it not possible to launch the H264 decoder ???
