selectPixelEncoder()

Channel::PixelEncoder fl::Channel::selectPixelEncoder ( const ChipsetVariant & chipset )

staticprivate

The chipset is fixed when a Channel is constructed, so bind its pixel encoder once instead of switching over every supported chipset on every frame.

The encoder callbacks remain channel-side: drivers receive ChannelData only after it has been encoded.
