Hello, I'm running FFMpeg Windos build from gyan.dev, in particular:
ffmpeg version 2021-11-03-git-08a501946f-full_build-www.gyan.dev I've got a NVidia GTX 560, which is running the latest possible driver 391.35. I also have a NVidia GTX 1060 running the latest possible driver 496.49. No matter what I do I cannot seem to get FFMpeg to use hardware acceleration. As per the wiki page (https://trac.ffmpeg.org/wiki/HWAccelIntro), I'm using the command: ffmpeg -i input -c:v h264_nvenc -profile high444p -pixel_format yuv444p -preset default output.mp4 This produces the output: [h264 @ 0000015275e66600] Cannot load cuvidGetDecodeStatus [h264 @ 0000015275e66600] Failed loading nvcuvid. [h264 @ 0000015275e66600] Failed setup for format cuda: hwaccel initialisation returned error. [h264_nvenc @ 0000015275ac4600] Driver does not support the required nvenc API version. Required: 11.1 Found: 8.1 [h264_nvenc @ 0000015275ac4600] The minimum required Nvidia driver for nvenc is 471.41 or newer Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height Conversion failed! I'm assuming this is due to the GTX 560 set as device 0, even so if I attempt to specify the use of device 1, which would appear to be GTX 1060: ffmpeg -hwaccel_device 1 -hwaccel cuda -i input -c:v h264_nvenc -profile high444p -pixel_format yuv444p -preset default output.mp4 I recieve the same error. In fact, even following the advice of Gyan (albeit 5 years old now) to list all GPUs (https://stackoverflow.com/a/40425932): ffmpeg -f lavfi -i nullsrc -c:v h264_nvenc -gpu list -f null - I'm receiving the same error: [h264_nvenc @ 0000020023f89ec0] Driver does not support the required nvenc API version. Required: 11.1 Found: 8.1 [h264_nvenc @ 0000020023f89ec0] The minimum required Nvidia driver for nvenc is 471.41 or newer Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height Conversion failed! Am I missing something here?
