 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?
