I am running Opera on Slackware 14.2. 64 bit. I had various problems with video playback which I solved by installing additional ffmpeg codecs and setting LD_LIBRARY_PATH to where ffmpeg.so is. That is a directory where Opera is installed. It took me a while to figure it out. Currently I am starting Opera from the script which sets and exports LD_LIBRARY_PATH. I know there are other ways, but this quick and, at the moment, everything works like in a perfect world.
I wonder how is it on other *NIX platforms ? Is there an install script which does something about it, or something else, or everyone has to figure it out for himself ? Perhaps a man page might help. For example I didn't know about additional ffmpeg codecs. As a result video playback worked, but it was not nearly as smooth and I had problems skipping forward and backward during playback. I must admit that my initial reaction was like "video is screwed", but I decided to dig deeper. I have seen many messages on this forum about it.
I have another question. Is there a way to tell Opera to open new instance in another window ? For example I have window with video maximized and need another one. When I launch new instance a new tab is open. I can drag it to desktop and create new window, but I have to leave maximized mode before it.
