The example command is Feb 13, 2023 · When using -hwaccel cuda -hwaccel_output_format cuda, the decoding process is CUDA accelerated, and the decoded video is located in the GPU. Replace format=nv12 with format=yuv420p To compile FFmpeg, the CUDA toolkit must be installed on the system, though the CUDA toolkit is not needed to run the FFmpeg compiled binary. You can always track GPU utilization and memory transfers between host and device by profiling the ffmpeg application using the Nvidia Visual Profiler, part of the CUDA SDK. To compile FFmpeg, the CUDA toolkit must be installed on the system, though the CUDA toolkit is not needed to run the FFmpeg compiled binary. Speed. I'm trying to figure out how to use the GPU for this (hopefully it is faster) but I haven't found anything that works. In terms of performance, don't expect much parity between them in terms of performance; both will run on the GPU either way. 264 videos at various output resolutions and bit rates. FFmpeg is a powerful and flexible open source video processing library with hardware accelerated decoding and encoding backends. CUDA Deinterlace Aug 2, 2022 · The output of ffmpeg -codecs shows: DEV. These command lines share the CUDA context across multiple transcode sessions, thereby reducing the CUDA context initialization time overhead significantly. ffmpeg -hwaccel vulkan -i input. One is the crf setting. ffmpeg is the same in that sense. With ffmpeg and a decent GPU (like a Quadro P4000) the h265/HEVC encoder finaly gets a good speedboost with up to 90fps when encoding HD movies with the below parameter values and 200fps when using the GPU accelerated h264 encoder. To utilize GPU acceleration with FFmpeg, you need a compatible NVIDIA GPU and the appropriate CUDA toolkit and drivers installed on your system. mp4" This produced a 828x processing speed: But for taking that same file and compressing it I seem to only get a ~8x Jun 28, 2022 · For GPU CUDA accelerated scaling we may use scale_cuda filter.
