#8599: ffplay with -left ignores -alwaysontop -------------------------------------+------------------------------------- Reporter: bposert | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: I am trying to play a file positioned on the left side of the screen in a topmost window. ffplay -alwaysontop [input file] displays on top as expected ffplay -left 0 -alwaysontop [input file] does not display on top. FYI winexplorer from nirsoft shows WS_EX_TOPMOST set when it works, and not set when it doesn't work. I've tried this on multiple input files of different types.
