gstreamer管道，用于在两个覆盆子pi之间传输多路复用的h.264和aac音频

Question

I have been stuck on this for days now. I am trying to come up with a GStreamer pipeline that will stream h.264 video and compressed audio (aac, mulaw, whatever, I don't really care) over a single rtp stream. The problem seems to always be with the multiplexer. I've tried asf, avi, mpegts, Matroska and flv multiplexers and it seems they are all oriented towards files (not network streaming) and are therefore requiring header information. Anyway, here's my latest attempt:

gst-launch-1.0 -e --gst-debug-level=4 \\ flvmux name=flashmux streamable=true ! flvdemux name=flashdemux ! decodebin name=decode \\ videotestsrc ! 'video/x-raw,width=640,height=480,framerate=15/1' ! omxh264enc ! flashmux. \\ audiotestsrc ! 'audio/x-raw,format=S16LE,rate=22050,channels=2,layout=interleaved' ! flashmux. \\ decode. ! queue ! autovideoconvert ! fpsdisplaysink sync=false \\ decode. ! queue ! audioconvert ! alsasink device="hw:1,0"

This pipeline removes rtp and simply feeds the decoder with the encoder. Also, this attempt uses raw audio, not encoded. Any help will be greatly appreciated!

Answer 1

1. To stream video+audio you should use 2 different ports.
2. Using rtpbin element to manage rtp session
