I finally merged your patch and also reworked subtitles rendering according to 
your comments. So now there is _input_subtitle texture that is prepared in 
prepare_next_frame and than blended into _color_srgb_tex in 
display_current_frame. Hope this is what you wanted.

Can you please test the new code and see if subtitles are rendered without 
OpenGL errors now? The only problem I see is alpha blending of video and 
subtitle textures - result is very dark.
The problematic code seems to be here: 
https://github.com/cuchac/bino/blob/master/src/video_output.cpp#L766

I think texture is created correctly in ARGB with transparent background and 
problem is in blending function, but I don't know how to fix it.

Bye,
Joe.
