WebJun 26, 2024 · The CUDA runtime API is state-based, and threads execute cudaSetDevice () to set the current GPU. After this call all CUDA API commands go to the current set device until cudaSetDevice () is called again with a different device ID. The CUDA runtime API is thread-safe, which means it maintains per-thread state about the current device. WebSo, if you have mlt version > 0.6.2, you can use multiple threads to speed up your rendering by several factors.

WebMultithreading is a form of parallelization or dividing up work for simultaneous processing. Instead of giving a large workload to a single core, threaded programs split the work into multiple software threads. These threads are processed in parallel by different CPU cores to save time.
