Error Intel QuickSync video and FFmpeg

Dear Master,

I want to make IPTV with a topology like this:

Restream / source -----> IPTV server -----> User

The problem at the moment is the question of bandwidth that is still large.

Finally I announced by IPTV software providers to transcode with Intel QuickSync video and FFmpeg.

I followed the steps given by the software provider at the following link:

Which comes from the link below:
https://www.intel.com/content/dam/www/public/us/en/documents/white-paper...

I installed IPTV software on a laptop with an Intel processor, chipset and VGA.

but when I do a transcoding test, an error always appears :
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.

Please help.
