Other Parts Discussed in Thread: TVP5146
Hello,
Our requirement is to demonstrate composite Video input streaming from DM365EVM using gstreamer to a Ubuntu 10.04 host PC. The encoder we desire to use is H.264 HP.
To test gstreamer pipelines, we have setup our development envt. as per http://processors.wiki.ti.com/index.php/DMAI_GStreamer_Plug-In_Getting_Started_Guide
We have managed to test some gstreamer pipelines using gst-launch but were unable to stream video from a composite Video input source, this is where we need your support.
We have managed to run the following successfully using gstreamer.
1) Display of composite video input source on TV (TV's composite input) after resizing it.
2) Streaming of a MPEG4 file after H264 compression to a Host PC through LAN.
To test composite Video input streaming from DM365EVM using gstreamer we tried the following:
# gst-launch v4l2src always-copy=FALSE input-src=composite num-buffers=800 ! TIVidResize contiguousInputFrame=TRUE ! 'video/x-raw-yuv, format=(fourcc)NV12, width=352, height=288, framerate=30000/1001' ! TIVidenc1 codecName=h264enc engineName=encode ! rtph264pay ! udpsink host=192.168.1.24 port=10000 -v
The response of "gst-launch" was as follows:
(gst-launch-0.10:1535): GStreamer-WARNING **: Failed to load plugin '/opt/gstreamer/lib/gstreamer-0.10/libgstmad.so': /opt/gstreamer/lib/libid3tag.so.0: undefined symbol: id3_fr

The above debug messages appeared 'OK' to us but as you can see the "caps = " messages is missing. Given below is an example of the "caps = " messages I am referring to.

We understand that to receive the streamed video the "caps =" string shown above needs to be passed to the "gst-launch" command on host PC but we are unable to find any "application/x-rtp" message in our current debug messages. Please let us know how could we sort out this issue.
