--- Comment #4 from Randeep <randeepk at tataelxsi.co.in> ---
Hi,

I need to use 'omxh264enc' gstreamer plugin to encode a video stream. When I
gst-inspect, it is showing the plugin details correctly (libgstomx.so), but
when i'm running it using a gstreamer pipeline i'm getting error as 'Could not
initialize supporting library' and additional debug info as:
videoencoder.c (1428): gst_video_encoder_change_state (): Failed to open
encoder.

    Is there any dependent library that we need to provide for this plugin to
work ? Can anyone please help me with this issue.


gst-launch-1.0 -v videotestsrc do-timestamp=true num-buffers=300 ! \

videoconvert ! video/x-raw,format=NV12 ! \
omxh264enc target-bitrate=3000000 ! \
