Hi, Thanks. I wil definitely mention you of any issues that I come across.
I have a few updates in mind: [1] Double buffering. I saw a few of the video_output samples in the vlc code and feel we may require it here as well. Are you seeing any tearing issues with the current code ? [2] I notice your driver calling clutter_texture_set_from_rgb_data and this will as I understand copy over the frame. Can there be some way to avoid this overhead ? There has been a mailchain initialited by Filippo Argiolas sometime back regarding sharing textures between 2 GL contexts and his findings may give us some lead. Do you agree ? Ethan.
