Hello everyone,

I am integrating hardware codecs in ffmpeg code.
But while I am trying decode video data using function virtual to physical memory it takes lots of time and memory.
The api used to copy data is ioremap.
Can any one suggest how can I reduce this overhead so that it takes less amount of time and memory.
