[GTALUG] Last Ubuntu OS Update Breaks ffmpeg

[Stephen]

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.
