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
