The hardware requirements for video miners are based on the computational resources required for transcoding.


A GPU with a built-in hardware video encoder/decoder is strongly recommended because it will significantly speed up transcoding and it will be difficult to compete for work in the marketplace without one. Transcoding capacity will scale with the number of GPUs available.

Currently, livepeer only supports Nvidia GPUs with NVENC (hardware video encoder) and NVDEC (hardware video decoder) support. For a list of of GPUs that have been tested and that are known to be supported by livepeer, see this page.


CPU transcoding using a software video encoder/decoder is possible, but not recommended due to its significant speed disadvantage relative to GPU transcoding. If you choose to do CPU transcoding (perhaps to try things out or as a temporary measure until a GPU is available), generally a CPU with more cores will improve transcoding speed.
