gst-launch -- Debugging suggesting to try to create compatible pipelines....

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


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
