DM36x JPEG+H264编码问题

我的DM368系统，需要在进行H264编码的时候，同时进行JPEG去完成图片抓拍。

单独创建和使用JPEG编码器和H264编码器都没有问题。但是当我先创建了JPEG编码器成功后，再去创建H264编码器，H264编码器就会创建失败。

反之先创建H264编码器成功，再去创建JPEG编码器就会失败。原因是JPEG和H264的EDMA资源限制，请教各位问题如何解决？十分感谢。

创建H264编码器失败的信息如下：

EDMAK Error: dma_ioctl: REQUESTDMA failed: -12

CMEM Error: allocHeap: Failed to mmap buffer at physical address 0x84192000
