I compile ffmpeg follow this post However, there isn't any example to use it with audio. ffmpeg cannot do it, and all the FFmpeg requires separate git repository nvcodec-headers for NV-accelerated ffmpeg build. executed at unknown time! ffmpeg -version. For the build: FFmpeg build with NVENC and all available CUDA-based filters on Ubuntu 18. The focus of this article is on using the FFmpeg. com Wed Sep 11 13:49:40 EEST 2024. 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. mp4 -vf fps=1/2 output-%04d. ffmpeg -hwaccel cuda -i 12. mp4 You may see an improvement in performance or GPU utilization. Before using FFmpeg, it is recommended to refer to the FFmpeg documentation, note the List options of a filter using ffmpeg -h filter=XXXX. You may be able to use hardware accelerated decoding. Start coding or generate with AI. Second issue is that format=nv12 is incompatible with the overlay filter. /configure --enable-cuda --enable-nvenc --enable-cuvid sorry for my bad english i have managed running ffmpeg with cuda support and libfdk-aac. VMAF key elementary metrics A docker container, with ffmpeg that supports scale_cuda among other things - aperim/docker-nvidia-cuda-ffmpeg In case we like to decode both input videos using GPU decoder, we have to download the video to the CPU before using concat filter, and upload after:. wav And I need to do it as fast as possible. . mp4 -s 224x224 -f image2pipe - -vcodec rawvideo ffmpeg lets you control quality in a variety of ways. Another setting is qp. scale_cuda=-1:720 means keep the same aspect ratio and match the other argument. ffplay -vcodec hevc_cuvid file. Whereas -c:v libx264 (or I guess -c:v h264works) will re-encode the video to a new H264 stream with default settings This will start a daemonset that'll look for GPU enabled nodes and will run the nvidia installer each time a node starts. We will cover the key concepts and provide detailed examples to help you get started. mp4 [FFmpeg-user] Using FFMpeg with Nvidia CUDA to crop and scale videos SMF Forum 1 smf. Replace format=nv12 with format=yuv420p The choice on the filter(s) you can use depend on how you build FFmpeg: Use the proprietary CUDA SDK and you'll get scale_npp and scale_cuda, or stick to an LLVM build without the CUDA SDK and you'll still get scale_cuda. Using Vulkan or Cuda to Encode AV1 on prior generation AMD and NVIDIA GPUs Have any of you guys researched using general purpose compute functionality to encode with In this article, we will explore how to use the FFmpeg. Use the example shown below. In your case, you'll need to build FFmpeg from source. To compile FFmpeg, the CUDA toolkit must be installed on the system, though the CUDA toolkit FFmpeg supports GPU acceleration through a feature called CUDA, which is NVIDIA's parallel computing platform and API. I compiled ffmpeg with the following flags:. png Sample H. mp4 -filter_complex . ffmpeg is amongst other things a wrapper for popular codecs like x264 and VP8 for video. One is the crf setting. Checking the logs under ffbuild/config. LS h264 H. Use FFmpeg command lines such as those in Sections 1:N HWACCEL Transcode with Scaling and 1:N HWACCEL encode from YUV or RAW Data. docker build -t ffmpeg . At this point, any pod with the GPU resources set and the right nodeAffinities will schedule on the GPU nodes and have access to the GPUs. Ask Question Asked 6 years, 4 months ago. Modified 6 years As far as I understood all of them just pass the encoding to hardware encoder, without actually using CUDA. forum1 at ntlworld. Some of those encoders are built to use GPUs, some are not. AutoGen library to perform CUDA decoding. I am using a NVIDIA GeForce GT 745M Graphics card (GPU:GK107), which is compatible with cuvid as specified by NVIDIA here. This is super low quality but fast and provides a small (but useless) file full of pixelation. What I am trying to achieve is to accelerate video encoding using plain old CUDA on old pre-Kepler hardware (GTX 570 here FFMPEG a few months ago launched the new version of FFMPEG with the new filter "overlay_cuda", this filter makes the same as the "overlay" but using an Nvidia card for applying Create high-performance end-to-end hardware-accelerated video processing, 1:N encoding and 1:N transcoding pipeline using built-in filters in FFmpeg; Ability to add your own custom high-performance CUDA filters using the shared CUDA context implementation in FFmpeg; Windows/Linux support * Support is dependent on HW. ffmpeg -y -vsync 0 -hwaccel cuda -hwaccel_output_format cuda -i my-video. nv-codec-headers Installation: Clones the nv-codec-headers repository and installs it, providing headers for Nvidia GPU accelerated video encoding/decoding. The reason it's lightning-fast is because it's not actually doing anything: Rather than re-encoding the video stream, it's basically copying the video stream bit-for-bit, out of the old file and into the new file. Sample decode using CUDA: ffmpeg -hwaccel cuda -i input output Sample decode using CUVID: ffmpeg -c:v h264_cuvid -i input output FFplay supports older option -vcodec hevc_cuvid, but not -c:v hevc_cuvid (though support for -hwaccel was recently added). AutoGen library to perform CUDA decoding, and we will assume that you have a basic understanding of CUDA and FFmpeg. Encode video with ffmpeg using CUDA without NVENC. mp4 Full hardware transcode with NVDEC and NVENC: I use ffmpeg to process some audios as follow, fmpeg -i input. 292. Use old. ffmpeg is the same in that sense. It's still running on the CPU. I try as follow, but it not work. mp4 -hwaccel cuda -hwaccel_output_format cuda -i intermediate2. The compiled ffmpeg has mostly common filter and other useful filter, support. See the shell scripts. 264 decode using CUVID: ffmpeg -c:v h264_cuvid -i input. mkv "hwdownload,format=p010le,format=yuv420p,hwupload_cuda" downloads frames from hardware to system memory in the original format (in this case p010le Using the example provided here, I was able to get FFMPEG to decode an HEVC encoded video via CUDA (as evidenced by Task Manager showing me that my test program is using 75% of the GPU). ) Old gcc means you can't compile new ffmpeg. Examples from FFmpeg Wiki: Hardware Acceleration - NVDEC. For the supported and available hardware accelerated features you can achieve with a current generation NVENC-capable NVIDIA GPU, see this answer. (Although, buying a new gpu is better. ! cp -r . If you have an NVIDIA GPU which supports hardware-accelerated video encoding and decoding, it’s simply a matter of compiling FFmpeg binary with the required support for NVIDIA libraries and This guide is to help you compile the latest ffmpeg with Nvidia CUDA and so much external library like libzimg, libplacebo in your local computer. I would like to go one step further and display those frames directly from the GPU - it would be a pity having to download them to the CPU (as the above sample code -c:v copy doesn't run on the GPU. mp4 \ -vf scale_npp=w=426:h=240 -c:v h264_nvenc -profile:v main -b:v 400k -sc_threshold 0 -g 25 \ -c:a aac -b:a 64k -ar 48000 \ -f hls -hls_time 6 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. Previous message (by thread): [FFmpeg-user] Using FFMpeg with Nvidia CUDA to crop and scale videos Next message (by thread): [FFmpeg-user] Regarding . Here is a sample of BAD quality CPU encoding using libx264 and a crf = 63. Run the container mounting the current directory to /workspace processing input. The example command is Once inside the container, as the default user anaconda, you can use the compiler to transcode using hardware acceleration. Sample decode using CUDA/NVDEC: ffmpeg -hwaccel cuda -i input. mkv -vf "hwdownload,format=p010le,format=yuv420p,hwupload_cuda" -c:v hevc_nvenc -preset slow test. Nothing that could be passed on to production The output of ffmpeg -codecs shows: DEV. So if you want to use libplacebo with CUDA, you need to compile libplacebo with version v6. ffmpeg -hwaccel cuda -i input output Sample decode using CUVID: ffmpeg -c:v h264_cuvid -i input output Full hardware transcode with NVDEC and NVENC: ffmpeg -hwaccel cuda -hwaccel_output_format cuda -i input -c:v h264_nvenc -preset slow output If ffmpeg was compiled with support for libnpp, it can be used to insert a GPU based scaler into the chain: After discuss with libplacebo author, there has some incompatible with ffmpeg master, CUDA. ffmpeg -hide_banner -loglevel warning -y -hwaccel cuda -hwaccel_output_format cuda -i intermediate1. Using x264 all attempts so far have produced mixed results at best. First off, it is much faster — about 5x faster in my case, although that varies with quality settings. o Error 255 / unsupported gpu architecture 'compute_30' during installation: If your ffmpeg was compiled with --enable-libnpp then consider using the GPU based scale_npp filter instead of scale which is CPU only. First, however, enter nvidia-smi to see whether the container can see your NVIDIA devices. log discovers this error: Cuda. In terms of performance, don't expect much parity between them in terms of performance; both will run on the GPU either way. add /user/local/cuda/bin: on the beginn of this file Downloading and Configuring FFmpeg: Downloads the latest FFmpeg source code, configures it with necessary flags for CUDA support, and compiles it. mp4" -c:v h264_cuvid -gpu:v 1 -preset slow -c copy "c:\testingvids\AEON FLUX 2005 nvidia. wget -q How to use CUDA GPU hardware encoding with ffmpeg to encode h264 and h264 HEVC movies in high quality and highspeed with our optimized parameter settings. The results of this collaboration are an extended libvmaf API with GPU support, libvmaf CUDA feature extractors, as well as an accompanying upstream FFmpeg filter, libvmaf_cuda. I can see there is FFmpeg resize using CUDA scale (filter scale_cuda is GPU accelerated video resizer ), full hardware transcoding example: $ ffmpeg -hwaccel cuvid -c:v h264_cuvid -i INPUT -vf scale_cuda=-1:720 -vcodec h264_nvenc -acodec copy OUTPUT. ffmpeg -y -hide_banner -threads 8 -hwaccel cuda -hwaccel_device 1 -hwaccel_output_format cuda -v verbose -i "c:\testingvids\AEON FLUX 2005. So I try to use nvidia cuda to accelerate it. Lastly, ensure that the compiled version of ffmpeg When using -hwaccel cuda -hwaccel_output_format cuda, the decoding process is CUDA accelerated, and the decoded video is located in the GPU. I installed vmaf from the latest commit, ran the tests. VMAF-CUDA must be built from the source. png FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. Check the installed ffmpeg version [ ] [ ] Run cell (Ctrl+Enter) cell has not been executed in this session. /configure and nonfree Messages sorted by: If you want to use on old Nvidia gpu, you can download my binaries, or compile one yourself. A value of 0 or 1 produces very good video. Remove hwupload_cuda from the beginning of the filter chain. Then i compiled ffmpeg with some minimal Here is the example command: time ffmpeg -hide_banner -hwaccel cuda -hwaccel_output_format cuda -i source. Why not using scale_cuda filter to replace to software based resizer? You don't need the proprietary npp filter since the cuda impl in ffmpeg is more than enough for you. /colab-ffmpeg-cuda/bin/. I tried to use different commands, but the result was always the same, on Windows and Ubuntu. mp4" This produced a 828x processing speed: But for taking that same file and compressing it I seem to only get a ~8x GPU based encoding is specific to a codec/GPU computing standard (CUDA, OpenCL) so you would need to specify what are you using in your case. wav -f wav -ar 16000 -ab 12800 -ac 1 output. ffmpeg is a whole lot of encoders and decoders and filters in one software package. Use nv-codec-headers old version if you want to use on old gpus. All came back ok, also the cuda tests. 1, and add disable_multiplane=1 in the ffmpeg command. hwupload_cuda; scale_cuda; scale_npp; thumnail_cuda; Build. 04LTS: I am trying to decode a video using the NVIDIA cuvid hardware acceleration with ffmpeg. cuda container as a reference for all required libraries and steps. Example from FFmpeg Wiki: Hardware Acceleration: ffmpeg -hwaccel cuda -i input -vf scale_npp=1920:1080 -c:v h265_nvenc output. My FFmpeg uses Video Codec SDK. Usage. Second, check to ensure that directory of ffmpeg is /usr/local/ffmpeg-nvidia by entering which ffmpeg into a shell. To utilize GPU acceleration with FFmpeg, you need a compatible NVIDIA GPU and the Here is how to use your Nvidia GPU to hardware accelerate video encoding with ffmpeg. Use the Dockerfile. /usr/bin/ Start coding or generate with AI. 264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders: h264 h264_v4l2m2m h264_qsv ) (encoders: libx264 libx264rgb h264_omx h264_qsv h264_v4l2m2m h264_vaapi ), and the transcoding process shows: [hevc @ 0x561e69691a00] Using auto hwaccel type vaapi with new default device. These command lines share the CUDA context across multiple transcode sessions, thereby reducing the CUDA context The question is whether it's possible to use CUDA cores to decode and encode video faster than the hardware engines (NVDEC and NVENC). tavx vzuqm xnnwybw udavb gtpqxhy pjaiif mdigvt xymhtkg wswre hsvvcd
