[gst-devel] [gst-embedded] transfer of video via udp/rtp/rtsp

Hi Wim,

As you said, I have edited the TIVidenc1 (mpeg4 encoder element) to include the missing headers. Now, the caps are properly set for the rtpmp4vpay and the udpsink, but I am still unable to see the video via UDP. For RTSP, I am able to see the first few frames only (Actually I see a constant image which corresponds to a frame for some time) and the output ends with a Bus error. I am also attaching a GST_DEBUG=2 output.

Thanks in advance.

Regards,
Neel.

Syntax 1:
gst-launch-0.10 -v filesrc location=foreman_422_vga._swap.yuv ! TIVidenc1 codecName=mpeg4enc engineName=encode contiguousInputFrame=FALSE iColorSpace=UYVY resolution=640x480 ! rtpmp4vpay ! udpsink port=1234

uh? if you fix the encoder/payloader the rtsp server will work as
expected.
