This is a forward of an email that I sent to the Fedora test list, because I was having a problem with mplayer (and vlc). Hi, I'm running F25. On Friday, mplayer worked as expected. I then updated to the latest updates (I have updates testing enabled). I didn't use mplayer again, and the next day, updated to the latest updates again. After that mplayer doesn't work properly. It runs way too slowly, and any video I play runs at about 1/8 speed. It complains that my system is too slow to run the video, a video is has run before without problem. I experimented, and the same behavior is true of vlc when run in X. However, when I run mplayer in a virtual console (with -vo fbdev2), it works properly except that it doesn't respond to keyboard commands when using the full screen. This might be another unrelated error, since its been a long time since I did that. ffplay works properly in X, but doesn't play the complete video, as it gets seek errors towards the end of the video. There was no kernel update, so this is not a problem with the video driver (radeon in my case). To look at this further, I then went to my rawhide installation and updated it to the latest version as of Saturday night. The same problems occurred there, so this is something common to both F25 and F26. I then returned to F25, and pulled the mplayer subversion repository, and compiled it to see if it would point to a problem. It compiled without problem, but the executable still has the problem. There were hundreds of updates, so it is hard to say which is the culprit, but I did notice that the xorg packages were updated. I also saw on the devel list that they excluded some libraries that had been previously included. I don't know if that would be relevant. I have no idea where to go from here. These programs aren't working for me, but I'm not sure why. I don't think it it the program itself, but a library it is using that changed. But *which* library?
