TCP Wrapper for QSVEncC

This is a tcp wrapper implementation for QSVEncC command from QSVEnc, simply sending the input & args to the server-side, and returning the output to the client with progress info printed to stderr.

Usage Scenario Considerable

• QSV encoding is preferred but the machine with QSV support is not the same one (Is this a valid case?)
• QSV is preferred in a VM, but it is hard or impossible to access it from the VM due to no GVT-g or reasonable SR-IOV support (i.e. Integrated 11th Gen Xe Graphics)

Components

• cmd/qsvencc-server is the server implementation, with configurable options below
  • -l --listen: tcp address to listen, with default value 192.168.122.1:11111
  • -c --cmd-path: path to qsvencc executable, with default value qsvencc
• cmd/qsvencc-client is the client implementation which could be a drop-in replacement of original qsvencc in the view of arguments, with additional options below
  • --remote-addr: tcp address to connect, with default value 192.168.122.1:11111

Why 192.168.122.1? Because that's the default IP address for KVM host from default bridge virbr0.

Special Note on KVM

Some configurations need to be tuned for an acceptable experience:

• virtio NIC is strongly recommended if your input is a raw video file / stream.
• at least mode='host-model' for the cpu configuration, or the CPU performance could be decreased dramatically.
