Chapter 6, Using the Matrox M264 Hardware Codecs
Overview of the Matrox M264 codecs
In order to use the Matrox M264 hardware codecs, you must have a Matrox M264
card.The codecs enable you to encode and decode 8- and 10-bit, 4:2:0 and 4:2:2
H.264/AVC multi-stream data. The Matrox M264 codecs support YUV 4:2:2 (8- and
10-bit) and v210 YUV uncompressed formats.You can use a Matrox M264 hardware
encoder for compression or a Matrox M264 hardware decoder for decompression
with resolutions ranging from proxy to UHD. However, this requires that you access
and control the codecs that you would like to use. For information on how to access
and control the Matrox M264 encoder, see
“About the Matrox M264 hardware
encoder” on page 25 . For information on how to access and control the Matrox M264
decoder, see “About the Matrox M264 hardware decoder” on page 29 .
¦ Note
On the Matrox M264/420 card, it is not possible to encode or decode
4:2:2 H.264/AVC content.
General characteristics
The following applies to compression and decompression operations:
• Although multiple instances of the encoder or decoder can be created, only one
compression or decompression stream can be opened on any instance.
• Up to 32 processes can be created at the same time.
