Re: [Bino-list] native 3D-TV support (request)

[Daniel Fratzscher]

Hi Martin!

tried your latest patch this weekend. The orientation of both frames 
seems correct (both frames at the same position in 3D-Mode) but at least 
in HDMI-mode they are half in heigt (like top-bottom-half). I did not 
tried the top-bottom of top-bottom-half modes if they behave the same, 
maybe I will do tonight.

Another question: since some time I compile bino against ffmpeg-mt. I 
remember you changed bino to support multithreading. Maybe it is better 
to compile against regular ffmpeg?

Best,
Daniel
