12 Codec Licenses
License keys for the hardware MPEG-2 and VC-1 codecs are included with the custom 16GB Raspberry
Pi Compute Module 3 NEC Edition. The licenses are programmed into the processor during production. It
is not necessary to purchase license keys.
All Compute Modules include hardware codec support for MPEG-4.
For the standard Compute Module 1 and 3, license keys for the MPEG-2 and VC-1 codecs can be
purchased from Raspberry Pi and added to the config.txt file for the following section:
# License Keys
decode_MPG2=
decode_WVC1=
Support for individual codecs can be confirmed using the following commands in a terminal window:
vcgencmd codec_enabled MPG2
vcgencmd codec_enabled MPG4
vcgencmd codec_enabled WVC1
