Example GStreamer Pipelines

To try out the TVP5150 board, the first thing you need to do is run the /bin/loadmodules.sh script.

Then connect a monitor to the NTSC output of the Leopard, and connect your video source to the RCA input connector of the TVP5150 board.

For a simple loopback, which displays the video source on the Leopards video output, try this pipeline:

fbset -disable; gst-launch -e v4l2src always-copy=false ! dmaiaccel ! TIDmaiVideoSink sync=false displayStd=v4l2 displayDevice=/dev/video2

If you have Darwin Streaming Server running on your Leopard, you can stream pretty decent live video with a pipeline like:

gst-launch v4l2src always-copy=false queue-size=6 ! videorate ! video/x-raw-yuv, format=(fourcc)UYVY, width=720, height=480, framerate=(fraction)15/1 ! dmaiaccel ! priority nice=-15 ! queue ! dmaienc_mpeg4 maxbitrate=3000000 targetbitrate=2000000 ! priority nice=-10 ! queue ! dmaiperf ! priority nice=-16 ! rtpmp4vpay ! udpsink port=5434 &
