To see which hardware codecs have been enabled, use “vcgencmd codec_enabled CODECNAME” whereCODECNAME is one of H264, MPG2, WVC1, MPG4, MJPG, or WMV9. For example:

1 vcgencmd codec_enabled H264

To see how the memory is split between the CPU and the GPU use:

vcgencmd get_mem arm && vcgencmd get_mem gpu

see how much free memory is available to the system use:

1 free -o -h
