The following replacement makes code compile (and run):

template <class TraitsType>
struct ChannelFormatConverter
{
//
//  ... code skipped ...
//
    template <class OtherTraitsType>
    inline static typename traits_type::value_type from(typename 
OtherTraitsType::value_type value)
    {
        return OtherTraitsType::template 
convert_format<traits_type::channel_format>()(value);
    }
//
//  ... code skipped ...
//
};

should be replaced with:

template <class TraitsType>
struct ChannelFormatConverter
{
//
//  ... code skipped ...
//
    template <class OtherTraitsType>
    inline static typename traits_type::value_type from(typename 
OtherTraitsType::value_type value)
    {
        typename OtherTraitsType::template 
convert_format<traits_type::channel_format> converter_type;
        return converter_type(value);
    }
//
//  ... code skipped ...
//
};


Imho, the first version just should not compile (no typename on a dependent 
type), it should report "undeclared type XXX" or something like that.
