Is there any function where I can process my encoded frame under GstVideoEncoderClass ?

Take a look at the existing hardware encoders based on GstVideoEncoder,
or most of the decoders based on GstVideoDecoder.

You can take the input from the video codec frame, and then at a later
time fill the output buffer in the frame and call
gst_video_encoder_finish_frame() on it once you're done. handle_frame()
and finish_frame() can even be in different threads, as is done in gst-
omx and the Android MediaCodec elements for example.
