Additional Inherited Members | |
| Protected Member Functions inherited from nvenc::nvenc_d3d11 | |
| bool | init_library () override |
| Required. Used for loading NvEnc library and setting nvenc variable with NvEncodeAPICreateInstance(). Called during create_encoder() if nvenc variable is not initialized. | |
| bool | wait_for_async_event (uint32_t timeout_ms) override |
| Optional. Override if you want to create encoder in async mode. In this case must also set async_event_handle variable. | |
| Protected Member Functions inherited from nvenc::nvenc_base | |
| bool | nvenc_failed (NVENCSTATUS status) |
| Check whether an NVENC API status represents failure. | |
| virtual bool | synchronize_input_buffer () |
| Optional. Override if you must perform additional operations on the registered input surface in the beginning of encode_frame(). Typically used for interop copy. | |
