Be it 3D Transform, Blur, complex Masking, or even custom shaders, you'll find it a FFmpeg uses _amf as the postfix for the AMF encoder names. 62. I've been trying to produce the kind of high quality you'd upload to Youtube or other such sites as a professional content creator (minimum quality loss, since the video will be re-encoded) and neither libaom or SVT-AV1 are capable of producing that kind of Summary of the bug: fast-forward or rewin on mp4 output of h264_amf doesn't work well, the audio works well when fast-forward, but the video will stuck for few seconds before it goes right. Added linux support for amf encoder through vulkan. h:451. 264 and HEVC This guide focuses on the encoder x264. c:91 AMFTraceWriter_Flush Originally released as a separate plugin, the FFmpeg Encoder feature allows you to use any FFmpeg video or audio encoder directly in the Streaming or Recording tab of OBS Studio. Previous message (by thread): [FFmpeg-devel] Added - HW accelerated H. I am running Windows 10 64-bit, and I recently changed from an nvidia GTX970 to a Radeon 5700 XT, using DDU to purge the drivers in Safe Mode along the way. FFmpeg 4. I have compared x264 with AMF using these settings and the only difference i can notice is x264 gives a less choppier image, but it's not bad at all on the AMF side neither. On windows 10, AMF at 60FPS 1080p works perfectly, on Linux StreamFX is a plugin for OBS® Studio which adds many new effects, filters, sources, transitions and encoders!

This should not be a replacement for obs-amd-encoder, but it should complement it. c. 264/AVC (via FFmpeg) AMD AMF H. I was doing software encoding with my 5600x and I hadn't looked much into the AMF encoder. Rate Control Methods. The code sample of the AMF encoder I root-caused the issue to a bug in the AMD AMF driver/runtime on pre-RDNA cards. mp4 As of OBS Studio 28.

This approach ensures that all multimedia while QueryOutput operates in another thread, maximizing the encoder's throughput. h264_amf to access AMD gpu, (windows only) h264_nvenc use nvidia gpu cards (work with windows and linux) h264_omx raspberry pi encoder; StreamFX is a plugin for OBS® Studio which adds many new effects, filters, sources, transitions and encoders! Be it 3D Transform, Blur, complex Masking, or even custom shaders, you'll find it a Is there a way to compile FFMPEG with 10Bit HEVC AMF encoder? I have only found ffmpeg build without 10bit AMF support. There might a chance the current ffmpeg installed from your distro's repository might already support it. It is recommend to use the defaults. Color Depth. I've tried the latest builds AMF/FFmpeg Options: I also compared the X264 very fast and your AMF encoder settings and it wasn’t that bad to each other in term of quality.

This effectively disables my vega gpu during boot and the rx 480 is the only accessible card. The "ultralowlatency" usage preset that Sunshine uses by default is broken on pre-RDNA cards in the current drivers. dmitrii at gmail. Discussion AMD Radeon division I request you to please launch an Nvidia NVENC encoder rival. Setup Different Linux Distros amdgpu-pro, FFmpeg, and OBS-Studio with AMF Encoding So you can enjoy high quality records , and to have something to shut up these Nvidia Boys Flexing their Nvenc encoder, Well AMF is your answer but on Color Range (Support for older Drivers). 0 of their utility, Fair point, though to end users the encoder is called amf_x264 and and used to be called VCE in other tools. From NVIDIA's website: . gyan. mp4 # use AMF HEVC HW encoder with the latency constrained variable bitrate method # for rate control, pre-analysis enabled, and AMF logging Filter the word “frame” indicates either a video frame or a group of audio as stored in an AVFrame structure Format for each input and each output the list of supported formats For video that means pixel format For audio that means channel sample they are references to shared objects When the negotiation mechanism computes the intersection of the formats supported at each end of The output of ffmpeg -codecs shows: DEV. In low latency modes output becomes available as soon as the first submitted frame I tried to encode video files using FFMPEG built with AMF support and found some unexpected behavior. mkv > output - Format of The Advanced Media Framework (AMF) SDK provides developers with optimal access to AMD devices for multimedia processing - AV1 Encoder · GPUOpen-LibrariesAndSDKs/AMF Wiki This document provides a complete description of the AMD Advanced Media Framework (AMF) Video Encoder Component. 3 ships with support for handling TrueHD in MP4, Intel QSV accelerated MJPEG and VP9 decoding, and on Linux the Vulkan-powered AMD AMF encoder is now supported.
