@denisftw I have lost count of the number of different solutions that have been put forward for these problems, all involving somehow obtaining a different version of libffmpeg.so which may not work with any other piece of software, and which can not be relied on to work with a particular version of Opera.
We're told it's because of patents, or mismatched library versions, or a library version needed specially for the new version of Opera which hasn't been released yet (and that all seems to miss the whole point of a library).
I am getting confused, and I am beginning to doubt if anyone else really knows a reliable answer. There seems to be too much of "It works for me so it must work for everyone."
I am trying to stay polite, but if "Tee-Emm" were still around and were dealing with computers, an award of The Most Highly Derogatory Order of the Irremovable Finger would already be in the post. Some of you deserve Season Tickets for your local ambulance service. The gabbling puts me in mind of a flock of chickens arguing over which end of the egg to to hatch from.
The most reliable fix seem to be to stop using Opera to read Twitter.
