Hi everyone,
I'm using the following pipeline to stream a mpeg2 video within mpegts stream with rtp.
gst-launch -e videotestsrc num-buffers=100 ! video/x-raw-yuv, width=176,height=144,framerate=25/1 ! decodebin ! ffmpegcolorspace ! queue ! videorate ! video/x-raw-yuv,framerate=25/1 ! ffenc_mpeg2video quantizer=4 gop-size=5 ! queue ! mpegtsmux ! rtpmp2tpay ! udpsink host=127.0.0.1 port=5000
gst-launch -e udpsrc port=5000 caps="application/x-rtp, media=video, encoding-name=MP2TS" ! rtpmp2tdepay ! mpegtsdemux ! queue ! ffdec_mpeg2video ! ffmpegcolorspace ! xvimagesink
Since mpegtsmux fragments the video stream, the rtp packets are composed of several mpeg2ts packets.
Hence my question is :
What is the meaning of the rtp buffer timestamp ? Is is the most recent / old mpeg2ts timestamp ? Is it meaningless ? something else ?
I'm mostly interested by the reception buffer timestamp (rtpdepay on the streaming client) but I guess the meaning is the same on the pay and depay side, isn't it ?
thanks a lot
Maxime
