Use a PNG with alpha-channel as Logo source.
If your logo source is PNG with alpha-channel, set logo_mode equal to 1, to keep transparency.
Note: the logo_transparent tag is only for usage with the vp6_flix output via XML.
Example XML:
<?xml version="1.0"?> <query> <format> <logo> <logo_source>[LogoURL]</logo_source> <logo_x>[LogoLeft]</logo_x> <logo_y>[LogoTop]</logo_y> <logo_mode>1</logo_mode> <logo_threshold>[LogoTreshold]</logo_threshold> <logo_transparent>[LogoTransparent]</logo_transparent> </logo> </format> </query>
