Impossible to convert between the formats supported by the filter 'Parsed_scale_npp_0' and the filter 'auto_scaler_0' Error reinitializing filters! Failed to inject frame into filter network: Function not implemented Error while processing the decoded data for stream #0:0 Conversion failed!Īlso there's things like hardware upload and download which I can't figure out. Use the command ffmpeg -i video1920.mp4 -vf scale640:360 video640.mp4 -hidebanner. To import your video, you need to open the command prompt or Powershell in the folder containing that video file. This code ffmpeg -y -hwaccel cuvid -i INPUT c:a copy -c:v hevc_nvenc -vf "scale_npp=w=1920:h:-1:format=yuv420p:force_original_aspect_ratio=decrease,pad=1920:1080:(ow-iw)/2:(oh-ih)/2" OUTPUT First of all, download FFmpeg and launch it on your computer. This code can't leave the video as it is if it's smaller than FHD. I'm not sure if I'm going to have problems using -hwaccel cuvid and nvenc but it seems to work fine. ffmpeg -y -hwaccel cuvid -i INPUT -c:a copy -c:v hevc_nvenc -vf "scale_npp=1920:1080" OUTPUT I want to use something like this -filter:v "scale='min(1920,iw)':min'(1080,ih)':force_original_aspect_ratio=decrease,pad=1920:1080:(ow-iw)/2:(oh-ih)/2"īut I've only gotten a very limited version of it to work. I have a 1070 with a recently compiled version of ffmpeg with just about everything enabled. (Not sure about OpenCL but it probably can) ffmpeg is a very fast video and audio converter that can also grab from a live audio/video source. ![]() I'm aware that Scale_Cuda, Scale_NPP and Vulkan that can do this. Software filters take forever, and since my encodes use nvenc anyway I thought I might as well give gpu resizing a shot. ![]()
