I'm trying to transcode H.264 Stream to HEVC. Everything just working 
fine when I'm using the in-built CPU decoder, but when I turn on the 
Hardware-accelerated CUVID module, it throws some error with most of my 
/root/bin/ffmpeg -hwaccel cuvid  -c:v h264_cuvid -i 
'udp://' -map 0:0:v -map 0:1:a -c:v hevc_nvenc -f 
mpegts test.ts

[h264_cuvid @ 0x3d2b800] Video height 14 not within range from 16 to 4096
Error while opening decoder for input stream #0:0 : Invalid argument

My video height with all of streams is HD or PAL resolution, so probably 
within that range.
stream #0:0 is the video stream.

I've tried to add -analyzeduration 10M -probesize 10M flags, the results

*It says: *
data partitioning is not implemented. Update your FFmpeg version to the 
newest one from Git. If the problem still occurs, it means that your 
file has a feature which has not been implemented.
[h264 @ 0x31df240] If you want to help, upload a sample of this file to 
ftp://upload.ffmpeg.org/incoming/ and contact the ffmpeg-devel mailing 
list. (ffmpeg-devel at ffmpeg.org)

I've already sent a mail to ffmpeg-devel at ffmpeg.org but I got no 
response from it.

Sample from input: https://1drv.ms/v/s!AlIDARy55xh44F7_i2Ak_q8bmTTF
The output file is empty.

My FFMPEG version is the newest: 4.0

CUDA Version: 9.2 (Patch installed)

Card: NVIDIA Quadro P2000

Using Ubuntu 17.10 and I've Centos 7  server with the same parameters.

If using something like this:
/root/bin/ffmpeg -i 'udp://' -map 0:0:v -map 0:1:a -c:v 
hevc_nvenc -f mpegts udp:// or file

It runs without an issue/warning.

I made a sample of a working stream too:
Input: https://1drv.ms/v/s!AlIDARy55xh44GA4yH34AIke-8Op
Output: https://1drv.ms/v/s!AlIDARy55xh44F-uJFXcvHsLTBw3
Sorry I can't provide the same sample, because the source stream coming 
from TV.

Is there anything which solves this kind of error? Am I doing something
