While trying this command:
kvazaar -i video.yuv --input-res 1280x720 -o video_tiled.hevc --roi roi.txt --slices tiles
I get this error:
Reading ROI file failed.
invalid argument: roi=roi.txt
Any ideas? Thanks!

Can you give the version of the encoder? `kvazaar --version` – Ahresse Sep 20 '17 at 11:08

Can you specify the content of `roi.txt`? – Ahresse Sep 20 '17 at 11:10

Thanks for your answer, @Ahresse. The version of Kvazaar is v1.1.0 and the content of roi.txt is: 64 64 20 40 40 64 64 20 40 40 64 64 20 40 40 – Sophie Sep 22 '17 at 07:18

Then `roi.txt` should contain "64 64 " followed by <64*64 = 4096> values. – Ahresse Sep 22 '17 at 08:39

Understood, thank you! – Sophie Sep 22 '17 at 09:42

Your roi.txt file must be incomplete and inadequate to the specified size.
About the roi.txt file:
(...) the first two values are the width and height, followed by width*height delta QP values in raster order.
Here is a link to the source code giving the error: [ https://github.com/ultravideo/kvazaar/blob/f8c5bb18a4604175f20dea673d14ca66257ac0c0/src/cfg.c#L1103 ]
