Matrox M264 S1/S2/S3
Matrox M264 cards feature hardware-based H.264 encoding and decoding capabilities. Depending on the card used, up to three UHD XAVC streams can be encoded/decoded simultaneously.
VizEngine as well as ChannelRecorder are capable of using the M264 cards for playback and capture of XAVC material, without affecting CPU performance.

The models S2 and S3 host (respectively) two and three encoder/decoder chips, so the number of possible streams is doubled/tripled.
M264 configuration
VizEngine
To enable VizEngine to use M264 cards, the serial number of the M264 needs to be added to the configuration file after the serial number of the installed X.mio3 or DSX LE 4 card.
Matrox.Devices = A123456,A654321ChannelRecorder
ChannelRecorder detects any installed M264 card automatically and uses it for encoding, when the XAVC UHD codec is used. No further configuration is necessary.
GPU Direct currently is not supported in combination with M264 hardware.
