Step 2: In the directory containing the FFmpeg. Working command without using GPU to scale: /usr/local/bin/ffmpeg -y -v warning -c:v hevc_cuvid -an -sn -dn -reconnect_at_eof 1 -reconnect_streamed 1 -reconnect_on_network_error 1 -i -c:v h264_nvenc -pix_fmt yuv420p -vf scale=1280:720 test_hevc.mp4īut when I try to scale using GPU for example scale_cuda or scale_npp I get this error:Ĭommand: /usr/local/bin/ffmpeg -y -v warning -c:v hevc_cuvid -an -sn -dn -reconnect_at_eof 1 -reconnect_streamed 1 -reconnect_on_network_error 1 -i -c:v h264_nvenc -pix_fmt yuv420p -vf scale_npp=1280:720 test_hevc. Step 1: Download and extract the necessary FFmpeg executables to aid in the task to turn H.265 into H.264. To install FFmpeg with support for libvpx-vp9, look at the Compilation Guides and compile. I was also using scale_npp=w=1280:h=720:format=yuv420p and scale_cuda - > no result. 265/HEVC AV1 VP9 Which is the Best Video Codec for Streaming. I use hevc_cuvid decoder and h264_nvenc encoder. How to convert pix format in hardware when transcoding 10 bit HEVC to h264 Accelerated Computing GPU-Accelerated Libraries tprice March 16, 2018, 9:17pm 1 Using the latest ffmpeg (3.4.2) compiled with the latest CUDA (9.1) I am unable to encode 10 bit h264 (see below output). How do I convert pix format in hardware, since apparently scalecuda does NOT support pixel format changes even though it can take that as an argument. (4K HEVC HDR to 1080p x264)>Is this ffmpeg command retaining HDR (4K HEVC HDR to 1080p. Default input is 10 bit hevc but I also try it on 8 bit hevc. tprice March 16, 2018, 9:17pm 1 Using the latest ffmpeg (3.4.2) compiled with the latest CUDA (9.1) I am unable to encode 10 bit h264 (see below output). ![]() For example, for h265 or hevc (these strings are interchangable) Codec: h265 Video Codec. Mit ffmpeg und einer anstndigen GPU (wie einer Quadro P4000) bekommt der h265/HEVC-Encoder von FFMPEG einen Geschwindigkeitsschub mit bis zu 90 fps beim. ![]() I am trying to transcode hevc to h264 using GPU. The NVENC plugin in FFMPEG supports the following codecs: h264nvenc - H264 Encoder hevcnvenc - HEVC Encoder av1nvenc - AV1 Encoder The command lines in this document use h264nvenc, and should be replaced by hevcnvenc for HEVC encode and av1nvenc for AV1 encode. Notes Codec: h265hevch264 Video Codec Parameters: h265hevch264.
