dmconf - Create, and load video format combinations for DM5 and Vpro Graphics
As shipped in IRIX 6.5.19. Added in IRIX 6.5.19.
NAME dmconf - Create, and load video format combinations for DM5 and Vpro Graphics SYNOPSIS /usr/gfx/dmconf [destination] [options] DESCRIPTION dmconf creates and operates on video format combinations, descriptions of raster sizes and timings to be used on video outputs. The resulting combination can be used as the current video configuration, or saved to a file for later use with the setmon(1G) command. To download a combination, dmconf requires write access to the /usr/gfx/ucode/STINGRAY/cmb directory. Options -destination [active | file <filename>] - This option specifies the destination of the video format combination. active specifies that the combination will be loaded as the current, active video configuration. The combination will be lost when graphics is reinitialized, or the system is rebooted. file specifies that the combination will be saved in a video format combination file <filename>. <filename> is specified relative to the current working directory. Combination files must be located in /usr/gfx/ucode/STINGRAY/cmb to be downloaded to the hardware. The following options modify the specified video format combination. -vpro [parameter|parameter=value,...] - Modifies the attributes for the vpro video output. format= <filename> - Specifies the video format to be used by the VPro graphics video output. -dm5 [parameter|paramteter=value,...] - Modifies the attributes for the DM5 video option colorspace= [ REC709_10 | REC709_8 | CCIR601_10 | CCIR601_8 | REC240_10 | REC240_8 ] - Specifies the colorspace to be output by the DM5. In the DM5 option, the RGB pixels from the framebuffer are converted into one of 3 colospaces, at either 8 or 10 bits per component. The three colorspaces are REC 709, CCIR601, and REC240. The default colorspace is REC 709 at 10 bits per component. decimationfilter= [ OFF | NARROW | SMPTE ] - Specifies how the 4:2:2 decimation filter is to be used. OFF turns off the decimation filter. DM5 will drop samples to get a 4:2:2 output. NARROW uses a 27 tap filter (... 0 0 1/4 1/2 1/4 0 0 ...). The primary use of this filter is for source images that are hard-edged, non-anti-aliased graphics where the decimation (no filter) would have serious color artifact aliasing and the SMPTE filter would show severe ringing. SMPTE uses the SMPTE standard decimation filter. The default is SMPTE. ecc= [ON|OFF] - Specifies whether the DM5 error correcting code option is to be used. The DM5 ECC attempts to detect and correct errors sent over the DVI link. The default value for ecc is ON. format= [ 1080I_5994 | 1080I_60 | 1080I_50 | 1080PsF_2398 | 1080PsF_24 | 1080P_2398 | 1080P_24 | 1080P_25 | 1080P_2997 | 1080P_30 | 720P_5994 | 720P_60 | 525I_5994 | 625I_50 ] - Specifies the video format to be output from the DM5. 525I_5994 and 625I_50 will be output from the SD output of the VBOB. All other formats will be output from the HD output of the VBOB. origin= w + h - Specifies the origin of the DM5 output in the framebuffer. The location is specified in pixels, and is relative to the upper-left corner of the screen. The default origin is 0+0. syncsource= [INTERNAL|EXTERNAL] - Specifies whether the DM5 is to attempt to genlock to an external source, or whether it is to free run. The default is EXTERNAL. EXAMPLES dmconf -destination file 1920x1154_2997r2+1080I.cmb \ -vpro format=1920x1154_2997r2 \ -dm5 format=1080I_5994 Creates a combination file 1920x1154_2997r2+1080I.cmb with the vpro running at 1920x1154_2997r2, and the DM5 outputting 1080I_5994. dmconf -destination file 1080I_offset.cmb \ -vpro format=1920x1154_2997r2 \ -dm5 format=525I_5994,origin=100+100 Creates a combination file 1080I_offset.cmb with the vpro running at 1920x1154_2997r2, and the DM5 outputting the 720x486I region with its origin at 100,100.
