- The FFmpeg commands used for each type of hardware in “Encode-Performance” are:
- Nvidia GPU with CUVID Acceleration: Utilizes Nvidia’s CUVID for hardware acceleration in decoding and NVENC for encoding.
- Command: ffmpeg -y -hwaccel cuvid -i input_video.mkv -c:v h264_nvenc -preset fast -c:a copy output_video.mp4
- Nvidia GPU with CUDA Acceleration: Leverages CUDA for hardware acceleration, with NVENC for encoding, tailored for Nvidia GPUs.
- Command: ffmpeg -y -hwaccel cuda -i input_video.mkv -c:v h264_nvenc -preset fast -c:a copy output_video.mp4
- AMD GPU Acceleration: Harnesses AMD’s hardware acceleration via AMF (Advanced Media Framework), specifically for AMD GPUs.
- Command: ffmpeg -y -hwaccel dxva2 -i input_video.mkv -c:v h264_amf -preset faster -c:a copy output_video.mp4
- Intel GPU Acceleration: Uses Intel’s Quick Sync Video (QSV) for hardware acceleration, designed for Intel integrated GPUs.
- Command: ffmpeg -y -hwaccel qsv -i input_video.mkv -c:v h264_qsv -preset fast -c:a copy output_video.mp4
- CPU-Based Encoding: For CPU-based encoding, utilizing the x264 software encoder, without GPU-based hardware acceleration.
- Command: ffmpeg -y -i input_video.mkv -c:v libx264 -preset fast -c:a copy output_video.mp4
- “certain videos, like those in 10-bit, cannot be encoded using h264_nvenc and require hevc_nvenc instead.
