I am trying to test out the TI H264 video encoder for the OMAP. I have managed to build the DVSDK and the GStreamer-TI plugins for my OMAP.
Now I am working on more general gstreamer issues, and (as a newbie to this package), I am flummuxed! I wanted to create a video stream in YUV format and just test that I can get it generated and saved. So, I used the following: > gst-launch videotestsrc pattern=1 num-buffers=3600 ! "video/x-raw-yuv, > format=I420, width=720, height=480" ! filesink location=sample.yuv But, when I run this, I get: r...@overo:~/data/videos# gst-launch videotestsrc pattern=1 num-buffers=3600 ! "video/x-raw-yuv, format=I420, width=720, height=480" ! filesink location=sampl e.yuv WARNING: erroneous pipeline: could not link videotestsrc0 to filesink0 I removed the filter in the pipeline and it worked, but I don't think I have control over the format of the video this way. r...@overo:~/data/videos# gst-launch videotestsrc pattern=1 num-buffers=3600 ! f ilesink location=sample.yuv Setting pipeline to PAUSED ...

Did I use the wrong syntax?
