what does video decode property mean in TX2 ?

TX2 has the video decode property with 4K x 2K 60 Hz. What does it mean ? If it can decode 4000*2000 resolution frame and the framerate achieves 60 fps ?
If I want to decode the stream with resolution 2048 * 1536 and the framerate 25 fps , I can decode how many cameras streams simultaneously ?

hello ClancyLian,

you could calculate the bandwidth by the following,

width* height* bits per pixel* number of planes* fps

there’s different maximum bandwidth capability according your decode standard.
please refer to R28.1 NVIDIA Tegra Linux Driver Package, check [Software Features]->[Software Features]->[Video Decoders] for more details.
thanks
