我有时使用此命令将 4k 视频转换为 1080p，使用工具“ffmpeg batch”和 ffmpeg 5.1 没有问题？ “2022-08-10-git-8fc7f0fdec-full_build-www.gyan.dev 版权所有 (c) 2000-2022 FFmpeg 开发人员使用 gcc 12.1.0 构建（Rev2，由 MSYS2 项目构建）”：
-map 0 -map -0:t -filter_complex "scale_cuda=1920:1080:format=yuv420p:interp_algo=lanczos,hwdownload" -fps_mode:v passthrough -c:v h264_nvenc -preset 18 -profile:v high -level 4.1 -b:v 13000K -rc cbr -c:a copy -c:s copy
这与预输入“-hwaccel cuvid”
现在，如果我尝试使用最新版本的 ffmpeg (6.1.1) 进行相同的操作，则它不起作用。我尝试使用“-hwaccel cuda”更改预输入，但仍然没有任何结果，它给我错误“无法找到未标记的输入板scale_cuda的匹配流：默认”。
如果我尝试在“scale_cuda”之前添加 [v:0]，我会收到此错误（在编辑命令之前也存在 pgs subs 错误）：

如果我尝试使用 -vf 而不是“filter_complex”：

有人可以告诉我现在使用 rtx 4090 执行此操作的正确方法吗？
显然我已经通过使用最新的 ffmpeg (v7) 和这个命令解决了：
-fps_mode:v 直通-filter_complex "scale_cuda=1920:1080:format=yuv420p:interp_algo=lanczos,hwdownload" -c:v h264_nvenc -preset 18 -pix_fmt yuv420p -profile:v 高 -b:v 13000K -an -sn
预输入：
-hwaccel cuda -hwaccel_output_format cuda
