我在IMX51系列的arm板子上测试飞思卡尔提供的jpeg解码，解码有两种格式，PPM和BIN，不知道这两种有什么区别。还有官方文档明明说支持jpeg硬解码，可是我用它的测试程序测试时。开启vpu支持，总是输出下列信息：
version: BLN_MAD-MMCODECS_JPEGD_ARM11_00.06.01 build on Jul 19 2010 17:31:49
[INFO] Product Info: i.MX51

init the callback input size (smaller value): 4096
vpu_enable: 1
reset the callback input size (bigger value): 262144
[WARN] VPU iram is less than needed, not use iram
vpu decode failure: 319

reset the callback input size (bigger value): 262144
4:2:0 convert
decode finish: width: 800, height: 600
Decoding Time: 17303 us
求指点。
