Rtpjitterbuffer does not output data

When I connect appsrc, rtpjitterbuffer and appsink together, rtpjitterbuffer uses RTP_JITTER_BUFFER_MODE_BUFFER mode. I have output a large amount of data through appsrc, but the entire pipeline cannot get the output.
May I ask what is the reason?

I found that when the percentage reaches 100%, gst_rtp_jitter_buffer_loop is not awakened. How can the data in the buffer be passed to the downstream?
