streaming task paused, reason not-negotiated (-4)

[pavan]

Hi Weipeng He,

Thanks for the input. Its working now. But actually i need to use the
omxh264enc to check the latency of the gpu in raspberry pi. But again im
getting the same problem. i've constructed the pipeline for omxh264 as
follows.

gst-launch-1.0 v4l2src do-timestamp=true !
video/x-raw,format=I420,width=640,height=480,framerate=30/1 ! timeoverlay !
omxh264enc ! video/x-h264,width=640,height=480,framerate=30/1 ! decodebin !
autovideosink sync=false

but i'm getting the same problem as v4l2src0: internal dataflow error.

I tried using the videoconvert as follows

gst-launch-1.0 v4l2src do-timestamp=true !
video/x-raw,format=I420,width=640,height=480,framerate=30/1 ! timeoverlay !
omxh264enc ! video/x-h264,width=640,height=480,framerate=30/1 ! decodebin !
videoconvert ! autovideosink sync=false

But the result is same. Plese provide me the suitable pipeline to use
omxh264enc on raspberry pi.
