I used it in a few microcontroller projects, let me get away with the cheaper 8 bit microcontroller with 64K of flash. The streaming decoding is real nice, because it can be read from flash and sent of to a display, without ever keeping it in ram. (4K!)
I don't think you could fit video on that microcontroller, even with the best compression. But some low memory and compute video compression for embedded devices would be nice.
