Decode a single picture (field or frame) More Post-process and map a video frame for use in cuda. To optimize video transcoding using FFmpeg with NVIDIA hardware acceleration, options like -hwaccel cuda and -hwaccel_output_format cuda are used to keep decoded frames in GPU memory, reducing latency and increasing throughput by minimizing PCIe bus transfers. It requires Netflix’s vmaf library (libvmaf) as a pre-requisite. I am trying to decode a video using the NVIDIA cuvid hardware acceleration with ffmpeg. They used to be called CUVID. 7k次，点赞5次，收藏25次。本文探讨了GPU硬解码原理及其实现方式，对比了不同硬件解码接口的特点，并详细分析了cuvid和VDPAU在视频解码 When I try to configure ffmpeg, it says: ERROR: cuvid requested, but not all dependencies are satisfied: cuda Newer ffmpeg will show a similar, re-worded message: ERROR: cuda requested, but not all ======================= Environment ======================= System: ubuntu 18. /configure - Custom commands for ffmpeg video conversion (CUDA): Here we can find a set of commands to use in video conversion with ffmpeg and common configurations (resolution, bitrate, encoding, etc), some This was true, but newer ffempeg implementations now use CUVID as a way to call NVENC/NVDEC, which is now reflected in the link provided in the documentation link at the bottom: FFmpeg is used by many projects, including Google Chrome and VLC player. After installing the library it can be enabled using: . c, which don't lose any functionality, even though > > half of the code is removed. 2. ffmpeg -init_hw_device cuda=gpu:0 -hwaccel cuda -hwaccel_output_format 文章浏览阅读3. The question is whether it's possible to use CUDA cores to CUDA (NVENC/NVDEC) NVENC and NVDEC are NVIDIA's hardware-accelerated encoding and decoding APIs. c > > and ffmpeg_cuvid. But the issue is about the decoder. When I check NVDEC Support Matrix, it says both encoding and decoding for H. I am using a NVIDIA GeForce GT 745M Graphics card (GPU:GK107), which is compatible with cuvid as specified by When I control available decoders using “ffmpeg -decoders | grep cuvid”, it gives the response given below. org/ffmpeg. You can easily integrate NVIDIA hardware-acceleration to these applications by Records using the H264_CUVID decoder in FFMPEG, Programmer Sought, the best programmer technical posts sharing site. 04 Architecture: x86_64 Display Card: NVIDIA GeForce 820m Display Card Driver: NVIDIA > On Fri, Feb 10, 2017 at 01:35:34PM +0100, wm4 wrote: > > From: Anton Khirnov < [email protected] > > > > > This will be useful in the following commit, after which linux freebsd ffmpeg gpu vaapi vdpau transcode nvenc cuvid Updated 2 hours ago Shell. 虽然FFmpeg本身有cuvid硬解，但是找不到什么好的资料，英伟达的SDK比较容易懂，参考FFmpeg源码，将NVIDIA VIDEO CODEC SDK的数据获取改为FFmpeg Broken by the previous Libav commit (even in Libav, thus a separate commit). c and Mirror of https://git. 文章浏览阅读7. It only accepts CUDA frames. More Context-locking: to facilitate 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.

And more specifically, about Cuvid decoders (h264_cuvid, hevc_cuvid and so on).
