Abstract:
Examples described herein relate to a system that after decoding of video by the first device, provides a memory address of decoded video in the memory device to a second driver for a second device and perform a second device driver that causes the second device to access the decoded video directly from a translation of the memory address of the memory device, wherein the second device is to access the decoded video with memory properties of the decoded video and decompression information of the decoded video. In some examples, the first device comprises one or more of: a graphics processing unit integrated with a central processing unit (CPU), a discrete graphics processing unit, or a video decoder accelerator. In some examples, the second device comprises one or more of: a graphics processing unit integrated with a central processing unit (CPU) or a discrete graphics processing unit. In some examples, the memory properties of the decoded video comprise swizzle information. In some examples, decompression information of the decoded video comprise a decompression scheme or decompression key.
