I am new to Gstreamer and looking for some basic testing of our DM365 EVM board.
I am running DVSDK4.01
- ti-dvsdk_dm365-evm_4_01_00_09
- linux kernel 2.6.32.17 (psp/linux-2.6.32.17-psp03.01.01.38)
- Component outputs hooked to monitor
- using NFS filesytem.
Following the 4.01 Software Development guide, I have successfully ran the H264 video on the display with the following command.
# gst-launch filesrc location=/usr/share/ti/data/videos/davincieffect.264 ! TIViddec2 codecName=h264dec engineName=codecServer ! TIDmaiVideoSink videoStd=720P_60 videoOutput=component sync=false hideOSD=true numBufs=3 useUserptrBufs=TRUE -v
I have tried to follow the examples listed here
http://processors.wiki.ti.com/index.php/Example_GStreamer_Pipelines#DM365
but it appears these are no longer valid with this version of Gstreamer..
So I wanted to build up the Gstreamer commands from the start and use "videotestsrc".
When I run
# gst-launch -v videotestsrc ! TIDmaiVideoSink

It looks like its complaining the video size is too small
"davinci_v4l2 davinci_v4l2.1: sizeimage is less, 691200"
I also try

Can you please comment on what I need to do to get this to work? Is this a bug or lack of documentation and understanding.
Thanks
