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 capable of using the M264 cards for playback and capture of XAVC material, without affecting CPU performance.

Info: The values above list the theoretical number of streams accelerated by the hardware. This does NOT state that a Viz Engine is able to process the same number as a lot of other factors influence the performance like Disc Speed, IO performance, Transfer Rates etc.

M264 Configuration

Viz Engine

To enable Viz Engine 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,A654321

Note: GPU Direct currently is not supported in combination with M264 hardware.

Channel Recorder

Channel Recorder detects any installed M264 card automatically and uses it for encoding, when the XAVC UHD codec is used. No further configuration is necessary.
