Rasperry Pi: jerkiness and interrupted audio during OSD

Reported by: Peter Bennett <pgbennett@…> Owned by:
Priority: minor Milestone: 0.28
Component: MythTV - Video/OSD Rendering Version: Master Head
Severity: medium Keywords: Raspberry pi
Cc: Ticket locked: no


On raspberry pi when the OSD is displayed the video becomes jerky and the audio cuts in and out. The bigger the area of screen in the OSD the worse it is.

I have a fix for this. Currently testing and improving it. I will post it here soon.

Fix is in the below referenced pull request

These fixes optimize the softblend process in several ways.

  1. Prevent blending OSD into frames that will be skipped.
  2. Multi threading designed by LVR to speed the OSD blending.
  3. Eliminate merging of areas of the OSD that are either opaque or invisible. For invisible areas: skip, for opaque areas: overwrite, instead of existing code that calculates a merge every time.

Performance with OSD is now almost perfect.
