Hello,
I tried with below versions of ffmpeg and lib264. And didn't get any
artifacts in the video. I have attached the output video.
trupti@debian64:~$ dpkg -l ffmpeg libx264-165

Thank you for your work, but unfortunately the bug persists. On the
pcc64el host platti.debian.org, I ran the following commands inside a
sid chroot:
(sid_ppc64el-dchroot)rafael@platti:~$ dpkg -l ffmpeg libx264-165
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)

(sid_ppc64el-dchroot)rafael@platti:~$ wget https://raw.githubusercontent.com/opencv/opencv/master/samples/data/vtest.avi
(sid_ppc64el-dchroot)rafael@platti:~$ ffmpeg -i vtest.avi -vcodec libx264 -to 2 out_h264.mkv
and the resulting file (attached to this message) still has the same
artifacts as before.
Best,
