Could you please also test with ffmpeg version 7.1.2? This is the only difference that I see between our two cases.

Best,

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.

# forgot to close the bug in the changelog close 1103936 2:0.165.3222+gitb35605ac-2 thanks

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)
    ||/ Name                Version                    Architecture Description

    (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,

Rafael Laboissière
