There are two problems here:

1) gst-rtsp-server seeks to position 0 after the PLAY command, which then
flushes away the first packet (and whole first encoded frame). It should at
least check if a seek is necessary at all, most of the time it isn't.

2) GstVideoEncoder should make sure the next frame after a flush is a keyframe.
