[vlc-devel] [VLC] #4319: libvlc_media_player_set_xwindow has some problem(bugs ?) :(

[ryanevans]

i got a following comment. 

>> ` The XID cannot be changed while the video is playing. This is not a
bug.`

so, I rebuild it using addWidget(insertWidget) and removeWidget with one
widget. next log for the widget(drawable).

[normal] addWidget id - 0x 88f4e88 (top level = 0 )
[full] removeWidget id - 0x 88f4e88 (top level = 1 ) 

but, output video failed. 
could you explain what i got a mistake ? 

thx.
