DVRRDK graphics output

Hi all,

I'm a little bit confused about the following in multich_progressive_vcap_venc_vdec_vdis.c:

grpxId[0] = SYSTEM_LINK_ID_GRPX_0;

grpxId[1] = SYSTEM_LINK_ID_GRPX_1;

#if 0 /* Enabling graphics only for ON CHIP HDMI and OFF CHIP HDMI */

grpxId[2] = SYSTEM_LINK_ID_GRPX_2;

#endif

You can find this in DVRRDK 3.0.0., 03.0.1. and 3.5.

Currently I use 3 graphics display outputs "/dev/fb0", "/dev/fb1", "/dev/fb2".

What's the relationship here ?

Best regards Holger

There are two options to use graphics in DVR RDK:

1. Use standard Linux fbdev

2. Use graphics links which run on M3 and similar to other links can be controlled via linkControl

The grpx links are not created in the multich_progressive_vcap_venc_vdec_vdis.c usecase so you can ignore the setting of grpxId.
