# BUGS
Direct mode (**-k**) does not yet support multiframe media. It'll read them
just fine, but only show the first frame. This might or might not change in
the future. Direct mode is kinda fundamentally suboptimal for multiframe
media. Until that time, **-k** is exclusive with **-d** and **-L**.
Direct mode is kinda fundamentally suboptimal for multiframe media, and
is not yet supported with **-L** nor **-d**.
