4 Video encoding and decoding processing performance 

The maximum width for H.264/H.265 encoding/decoding is 2688, and the maximum resolution is 2688x1944. It only supports decoding its own encoded streams. 

The multi-stream real-time encoding (decoding) capability of H.264/H.265: 

- 2688x1536 @ 30fps encoding + 720x480 @ 30fps encoding + 360x240 @ 30fps encoding 

- 2688x1944 @ 20 fps encoding + 720x480 @ 20 fps encoding + 360x240 @ 20 fps encoding 

- 1920x1080 at 30fps encoding + 720x480 at 30fps encoding + 1920x1080 at 30fps decoding
