Comment (by wammer):

 I'm seeing the same error with a Tesla T4 GPU:

 {{{#!bash
 ffmpeg -i in.mp4 -init_hw_device vulkan -vf
 hwupload,libplacebo=format=yuv420p,hwdownload,format=yuv420p out.mp4
 }}}

 {{{
 [AVHWFramesContext @ 0x55dc4152e640] There are no supported modifiers for
 the given sw_format
 [Parsed_hwupload_0 @ 0x55dc4152ac00] Failed to configure output pad on
 Parsed_hwupload_0
 }}}

 Ubuntu 22.04.1 LTS
 Vulkan Instance Version: 1.3.231
 CUDA Version: 11.7
 Input file: Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709,
