FLV4 is the Flash Video file format, apparently inside the Matroska (mkv) file container. You can read for example http://en.wikipedia.org/wiki/Flash_Video http://en.wikipedia.org/wiki/Matroska Flash video should be playable in general by mplayer, with the usual codec suite, nothing special. So if it doesn't work for you, there are two possibilities: 1) The file is broken. Are you able to play it elsewhere? On Windows? Where did you get it? Maybe the download was bad, can you check md5sum or similar? 2) Your mplayer configuration is broken somehow. Post the complete output of "mplayer -v insertfilename". The line > > = Cannot find codec matching selected -vo and video format 0x34564C46. is begging the question what video output driver do you use (do a "mplayer -vo help" to see all options available for you, see "man mplayer" and other docs to read about them). The usual driver is xv, and if that doesn't work for some reason, the usual second choice is x11. You can try to force mplayer to use one of them: mplayer -vo xv insertfilename mplayer -vo x11 insertfilename The video output driver of mplayer is usually determined by the capabilities of your graphics hardware. What card do you have ("lspci | grep vga")? What drivers do you use for it? Do you see anything suspicious while playing other movies with mplayer?
