Since it simply uses the FFmpeg integration and exposes it to OBS Studio, including all the necessary zero-copy logic, you can switch your stream over, set some parameters, and get started. Needless to say, it always massively outperformed h264_nvenc in terms of quality for a given bitrate, while also being slightly faster. NVIDIA NVENC (via FFmpeg) With the new NVIDIA NVENC integration through FFmpeg you can achieve greater recording and stream quality, at no extra expense. Using the 'slow' preset, av1_nvenc outperformed hevc_nvenc in terms of encoding speed by 75% to 100% while performing above tests. NVENC - Hardware-Accelerated Video Encoding Introducing AV1 encoding with Video Codec SDK 12.0 on NVIDIA’s Ada architecture. Notably, as far as I know libx264 and libx265 are CPU only A video game may do some parts using a GPU, but other parts using a CPU. ffmpeg needs to be built with the -enable-gpl -enable-libx265 configuration flags and requires x265 to be installed on your system. Some of those encoders are built to use GPUs, some are not. 264 using ffmpeg can give you better quality/size ratio than the original file. youd cd to the ffmpeg source in a terminal (or if using 16. In This Video We Will Learn How To Fix OBS Studio NVENC Codec Error. It produces fewer artifacts and the ones it does produce are less jarring to my perception.Īt higher bitrates I had a hard time finding differences between the two encoders in terms of subjective visual quality. ffmpeg is a whole lot of encoders and decoders and filters in one software package. /configure is run from the ffmpeg source, i.e. In terms of quality at low bitrate cbr settings, it seems to outperform it even. The encoder seems to be trading blows with hevc_nvenc. This includes hardware acceleration (HWA) of video decoding/encoding in tools like FFmpeg or HandBrake CLI using the NVIDIA NVDEC/NVENC decoder/encoder. Timo Rothenpieler merged the NVENC AV1 encoding support and summed it up as: This weekend, FFmpeg added support for using NVENC AV1 with the new NVIDIA GeForce RTX 40 series cards. With the Intel Arc Graphics, AMD Radeon RX 7000 series, and NVIDIA GeForce RTX 40 series, GPU-accelerated AV1 encoding is now widely available for this royalty-free video codec that is becoming more and more popular.
