hi,

i read https://www.ridgerun.com/developer/wiki/index.php/Using_DVI_Output_on_DM365Leopard.

i find gst-launch videotestsrc ! TIDmaiVideoSink videoStd=PRGB
the tidmaivideosink has only videoStd property.where dose tidmaivideosink output video to,composite or lcd or dvi?what is videoOutput property of tidmaivideosink?

if videooutput is null ,i could not find its default value in tidmaivideosink source code "gsttidmaivideosink.c".

any comment? thanks

Hi,

Well I dont think that the videooutput default values is something that may help you, but i'm sure that the PRGB is there, when I run gst-inspect TIDmaiVideoSink i get (i'm just pasting what is important):

videoStd : Video Standard used

AUTO (if supported), CIF, SIF_NTSC, SIF_PAL, VGA, D1_NTSC

D1_PAL, 480P, 576P, 720P_60, 720P_50, 1080I_30, 1080I_25

1080P_30, 1080P_25, 1080P_24, PRGB

flags: readable, writable

String. Default: null Current: null

videoOutput : Output used to display video (i.e. Composite, Component, LCD, DVI)

flags: readable, writable

and I follow the same guide that you used, and used this pipe:

gst-launch v4l2src chain-ipipe=true always-copy=false ! "video/x-raw-yuv,format=(fourcc)NV12, width=1280,height=720,framerate=(fraction)23/1" ! dmaiaccel ! TIDmaiVideoSink videoStd=PRGB sync=false enable-last-buffer=false

Maybe your missing something
