Matrox M264 S1/S2/S3/S4
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. Viz Engine and Channel Recorder are both capable of using the M264 cards for playback and capture of XAVC material, without affecting CPU performance.

Note: Since the S2 and S3 models host two and three encoder/decoder chips respectively, the number of possible streams is doubled/tripled.
M264 Configuration
Viz Engine
To enable Viz Engine to use M264 cards, the serial number of the M264 must be added to the configuration file after the serial number of the installed X.mio3 or DSX LE 4 card.
Matrox.Devices = A123456,A654321
Note: GPU Direct is not currently supported in combination with M264 hardware.
Channel Recorder
When the XAVC UHD codec is used, Channel Recorder automatically detects any installed M264 card and uses it for encoding. No further configuration is necessary.
