Comment 10 for bug 661735

Same problem on xenial in an Acer Aspire One 255 (AOD255E), also in VLC. gnome-mplayer shows the video but at a very slow frame rate, and in cases where it has to scale the image up to make it fill the screen, the image quality is worse than on an Acer Aspire One 360 with VLC (same resolution, full screen, no frame skips). I guess that gnome-mplayer used software rendering, most probably because hardware video acceleration was unavailable. The latter would explain why other media players failed.

Also a Thinkpad on precise started to have the all-black video problem some time in spring or summer of 2016; I had thought this was just an end-of-support thing precise is quite old now. On the Thinkpad, VLC and gnome-mplayer also show the video as just black.
