Other Parts Discussed in Thread: OMAP3530
hi
I'm using monta vista kernel 2.6.32 and dvsdk_3_10_00_19, and ti gstreamer is the newest version down from svn.
my bootargs is 'mem=65M console=ttyS0,115200n8 root=/dev/mtdblock3 rootfstype=yaffs2 rw video=davincifb:vid0=OFF:vid1=OFF:osd0=800x480x16,4050K dm365_imp.oper_mode=0 davinci_enc_mngr.ch0_output=LCD davinci_enc_mngr.ch0_mode=800x480 vpfe_capture.cont_bufoffset=0 vpfe_capture.cont_bufsize=6291456'
The start up log message and image can be display on the lcd use /dev/fb0 device, and use ti gstreamer to decode video stream output to TV with ntsc/pal mode succesful.
my gstreamer scripts like this
gst-launch -v filesrc location=/opt/davincieffect_ntsc.mpeg4 ! TIViddec2 codecName=mpeg4dec engineName=codecServer ! dmaiperf print-arm-load=TRUE ! TIDmaiVideoSink useUserptrBufs=TRUE displayStd=v4l2 displayDevice=/dev/video2 videoStd=D1_NTSC videoOutput=composite sync=false
This scrpits works well, but when I use this scrpits:
gst-launch -v filesrc location=/opt/davincieffect_ntsc.mpeg4 ! TIViddec2 codecName=mpeg4dec engineName=codecServer ! dmaiperf print-arm-load=TRUE ! TIDmaiVideoSink displayStd=fbdev displayDevice=/dev/fb0 videoStd=VGA videoOutput=LCD sync=false
it decoded failed, and show the error message like this,
.......................................
Setting pipeline to PLAYING ...
New clock: GstSystemClock
ERROR: from element /GstPipeline:pipeline0/GstTIDmaiVideoSink:tidmaivideosink0:
Unable to initialize display
.............................
hence, I followed along with Eric's suggestion to modify gsttidmaivideosink.c to support LCD output at the case VAR_VIDEOUTPUT.
The orignal code:
#if defined(Platform_omap3530)
else if (!strcmp(sink->videoOutput, "DVI"))
return Display_Output_DVI;
else if (!strcmp(sink->videoOutput, "LCD"))
return Display_Output_LCD;
#endif
Does it mean that only omap3530 can support output to LCD?
I commented define Platform_omap3530, and recompiled it, but when I use "videoStd=VGA videoOutput=LCD" , show the same error message.
Any suggestion?
thanks a lot.
