Bare H264 bytestream have no time information. Use a container like
MP4, MKV, FLV, TS, etc in order to store you videostream with
appropriate time information. As an example:

gst-launch-1.0 ksvideosrc ! image/jpeg,width=1280,height=720,framerate=60/1 ! jpegdec ! videoconvert ! x264enc ! matroskamux ! filesink location=video.mkv
