Hi all, I am using the below pipeline to work as a RTSP client. gst-launch rtspsrc location=rtsp://localhost:8554/jurassic.mp4 latency=200 name=d d. ! queue ! rtph264depay ! ffdec_h264 ! ffmpegcolorspace ! ximagesink d. ! queue ! rtpmp4adepay ! faad ! audioconvert ! autoaudiosink I wanted to handle PLAY & PAUSE operations on client side. So I have modified the "rtspsrc" plugin's source code to handle the keyboard inputs. I have created a thread which calls a callback function in the file gstrtspsrc.c to detect the key hit. I am creating & running this thread from the gst_rtspsrc_init() function. When I hit the key 'p' from my keyboard I change the state of the of the "rtspsrc" element to PAUSED & with the next hit of key 'p' I change the state to PLAYING. This addition does play & pause but the play after pause change doesn't happen immediately and sometimes the video isn't smooth. Am I doing PLAY & PAUSE properly? If not could someone suggest me a better way to do the same. If its right how do I improve the video display & avoid the delay for play after pause. Thanks in advance.
