Description (last modified by danielk) (diff)

Per Danielk I'm creating this ticket and attaching a copy of the output of mythtv -v playback for one of the files I have which when played with the xv-blit renderer have a line of green pixels overlayed at the very bottom of the video.

Pics of it are here: http://www.phaze.org/mythtv/greenline/

Both videos showing the line have a height of 304 pixels, and it shows up in all X resolutions I've tried.

(In [15034]) Refs #4248. Fixes the main 'clear to black' function to use the buffer strides rather han the frame width.

greg, did [15034] fix the greenline for you?

  • Status changed from new to closed
  • Resolution set to invalid

Greg discovered that MythTV was applying a 105% scaling to his frames due to a missing config parameter in his DB.

There is a bug in the nVidia drivers which sometimes cause this type of problem when a negative offset is applied to an XVideo frame :[

Changing this to "invalid", since it appears to be a driver bug causing the green line.
