Copy macroblock data to a buffer before encoding it I got this idea from Pascal (Thanks). Before encoding a macroblock, copy it to a 16x16 buffer, and then read source data from there instead. This will help keep the source data in cache, and help with the performance. Change-Id: Id05f4cb601299150511d59dcba0ae62c49b5b757
