ARGB32转NV12会卡死，怀疑是ARGB32的问题。mRga->ops->setSrcFormat(mRga, V4L2_PIX_FMT_ARGB32, width, height);
mRga->ops->setDstFormat(mRga, V4L2_PIX_FMT_NV12, width, height);
mRga->ops->setSrcBufferPtr(mRga, srcBuf);
mRga->ops->setDstBufferPtr(mRga, dstBuf);
mRga->ops->go(mRga);

NV12拷贝去编码器可以
mRga->ops->setSrcFormat(mRga, V4L2_PIX_FMT_NV12, width, height);
mRga->ops->setDstFormat(mRga, V4L2_PIX_FMT_NV12, width, height);
mRga->ops->setSrcBufferPtr(mRga, srcBuf);
mRga->ops->setDstBufferPtr(mRga, dstBuf);
mRga->ops->go(mRga);

mRga->ops->setSrcFormat(mRga, V4L2_PIX_FMT_ARGB32, srcBuf_width, srcBuf_height);
mRga->ops->setDstFormat(mRga, V4L2_PIX_FMT_NV12, dstBuf_width, dstBuf_height);
mRga->ops->setSrcBufferPtr(mRga, srcBuf);
mRga->ops->setDstBufferPtr(mRga, dstBuf);
mRga->ops->setSrcCrop(mRga, srcX, srcY, srcW,srcH);
mRga->ops->setDstCrop(mRga, dstX, dstY, dstW,dstH);
mRga->ops->go(mRga);

感觉只要有V4L2_PIX_FMT_ARGB32就会出错，是不是内核驱动里面这个作为源不支持？

这LOG显示你自己内存越界了。
玩嵌入式都要注意硬件宽高都有16对齐，buffer都要按对齐的开

srcBuf_width, srcBuf_height,需要16进对齐是吧
