h264_nvenc: InitializeEncoder failed: invalid param (8): Frame Dimension less than the minimum supported value.

[kvsico]

When I use h264_nvenc, small video(width < 145 or height < 145) always failed, the command is w=144 h=144 node nvenc-frame-dimension.js, it throws error like

`
[h264_nvenc @ 0x55a8a4356100] InitializeEncoder failed: invalid param (8): Frame Dimension less than the minimum supported value.
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!
`

but w=145 h=145 node nvenc-frame-dimension.js works successfully, does the minimum value is 145?

That error is coming right from the driver.
The minimum resolution might even vary depending on driver or hardware version, but there's nothing ffmpeg can do about it, it's a limit of the driver.
