Ok, I think I understand the 'filter' syntax better (thanks for the feedback) in gst-launch.
I am now trying to get the video source to output a stream that is compatible with the TIVidenc plugin.
% gst-launch videotestsrc pattern=1 num-buffers=60 ! "video/x-raw-yuv, format=UYVY" ! TIVidenc codecName=h264enc engineName=codecServer
WARNING: erroneous pipeline: could not link videotestsrc0 to tividenc0
Using gst-inspect, it looks like the TIVidenc needs a UYVY format (as I selected above). See below.
Since the TIVidenc wants a framerate, width and height, I tried to include a filter for that, but this gave the same error.
root at overo:~/data/videos# gst-launch videotestsrc pattern=1 num-buffers=60 ! "video/x-raw-yuv, format=UYVY,width=720,height=480,framerate=15" ! TIVidenc codecName=h264enc engineName=codecServer
WARNING: erroneous pipeline: could not link videotestsrc0 to tividenc0
root at overo:~/data/videos#
Any suggestions on how to debug this to find a compatible pipeline?
Thanks,
Charlie
