Last Ubuntu OS Update Breaks ffmpeg
And help and/or advise appreciated. I am using 18.4 and apply all updates. I have been using ffmpeg for many years to convert file formats. I am now getting errors that have me confused. Here is the command line: ffmpeg -i 101.Cat.avi -c:v libx264 -c:a copy 101.Cat.mp4 I now get many errors: libGL error: unable to load driver: i965_dri.so libGL error: driver pointer missing libGL error: failed to load driver: i965 libGL error: unable to load driver: i965_dri.so libGL error: driver pointer missing libGL error: failed to load driver: i965 libGL error: unable to load driver: swrast_dri.so libGL error: failed to load driver: swrast X Error: GLXBadContext Request Major code 155 (GLX) Request Minor code 6 () Error Serial #55 Current Serial #54 I Google the errors and everything seems to focus on bugs in Android Studio which I don't use. So I am at a loss for how to fix this. -- Stephen
Could be a power state issue. I just recently added intel_pstate=skylake_hwp to my grub while working on my own build. If it is a similar issue, perhaps the instructions on this page will help. IIRC I added this to F27 but not yet to F28, just to make sure I didn't break anything. My video stuttering issue is really with F28. https://blogs.igalia.com/vjaquez/2017/12/07/enabling-huc-for-sklkbl-in-debia... On Thu, Sep 13, 2018 at 8:16 AM Stephen via talk <talk@gtalug.org> wrote:

I have no particular knowledge of this, but I'll take a whack at it. What is libGL? Read this: <https://dri.freedesktop.org/wiki/libGL/> It looks as if ffmpeg is trying to use your graphics card to help with the conversion. libGL is unable to load a driver. Since one of the later choices appears to be a pure-software driver "swrast_dri", your problem isn't missing hardware. I'd guess the libgl used by ffmpeg is obsolete and out of sync with /usr/lib64/dri/. Or perhaps you are using a 32-bit ffmpeg on a 64-bit system, or vice versa. Have a look in /usr/lib64/dri/ and /usr/lib/dri/. Are both populated? For example, on my system, I have: /usr/lib64/dri/swrast_dri.so Did you install ffmpeg from the ubuntu repositories? If not, it might be out of sync with the other components (like libGL) which do get updates from the ubuntu repositories. How did you update ubuntu? Sometimes you need to use "apt-get dist-upgrade", not just "upgrade".

I always update with dist-upgrade, precisely to avoid missing drivers and other auxiliary files. I haven't experienced problems yet (~5 years of doing this). --Bob. On 14/09/18 11:04 AM, Lennart Sorensen via talk wrote:
