Title:
easycap kernel module; 12% dropped frames while playback
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
While playing any video source with the EasycapDC60 device (with or
without audio playback at the same time) ~ 10% frames are dropped with
mplayer (and also if the Easycap is used with VLC or Tvtime).
I suppose this issue is related to the staging/easycap kernelmodule.
I found this thread on lkml.org concerning the staging/easycap module:
