Gstreamer rtsp playing (with sound)


im newbie in gstreamer and simple try to wath rtsp video flow from Dlink 2103 camera.

When i trying it (just video):

gst-launch rtspsrc location=rtsp://192.168.0.20/live1.sdp ! \
rtph264depay ! \
h264parse ! capsfilter caps="video/x-h264,width=1280,height=800,framerate=(fraction)25/1" ! 
ffdec_h264 ! ffmpegcolorspace ! autovideosink

Its ok.

When i trying it (just audio):

gst-launch rtspsrc location=rtsp://192.168.0.20/live1.sdp ! \
rtpg726depay !  ffdec_g726 !  audioconvert ! audioresample ! autoaudiosink

Its also ok.

Next i try play both audio and video. gst-launch man page was used for generate something like this:

gst-launch-0.10 -m -vvv -e  rtspsrc location=rtsp://192.168.0.20/live1.sdp  latency=1000  ! \
gstrtpptdemux name=demuxer  demuxer. ! \
queue ! \
rtph264depay  ! h264parse ! capsfilter caps="video/x-h264,width=1280,height=800,framerate=(fraction)25/1" ! \
ffdec_h264 ! ffmpegcolorspace ! autovideosink demuxer. !  \
queue ! 
rtpg726depay !  ffdec_g726 !  audioconvert ! audioresample ! autoaudiosink

But video freez with first frame. I also try this classic way using decodebin (both 1 and 2 ver):

gst-launch-0.10 -v  souphttpsrc rtspsrc location=rtsp://192.168.0.20/live1.sdp  ! 
decodebin name=decoder decoder. ! queue ! audioconvert ! audioresample ! 
autoaudiosink decoder. ! \
ffmpegcolorspace ! autovideosink

BUT it also freez on first frame.

ONE way i have success it using playbin...

gst-launch-0.10 playbin2 uri=rtsp://192.168.0.20/live1.sdp

IS IT my bad pipeline or something wrong with dlink camera? Can you tell me key-word that i should to learn more?

thanks in advance !


Solution

  • Solution 1 (Tested)

    Ok I made my own RTSP server to test

    I created a RTSP server using video and audio test srcs using the following info ( http://www.ip-sense.com/linuxsense/how-to-develop-a-rtsp-server-in-linux-using-gstreamer/ )

    Makefile

    # Copyright (c) 2012 enthusiasticgeek
    # RTSP demo for Stack Overflow
    
    sample:
        gcc -Wall -I/usr/include/gstreamer-0.10 rtsp.c -o rtsp `pkg-config --libs --cflags gstreamer-0.10 gstreamer-rtsp-0.10` -lglib-2.0 -lgstrtspserver-0.10 -lgstreamer-0.10
    

    Tested the decoding pipeline. It works fine!

    gst-launch -v rtspsrc location="rtsp://localhost:8554/test" name=demux demux. ! queue ! rtph264depay ! ffdec_h264 ! ffmpegcolorspace ! autovideosink sync=false demux. ! queue ! rtppcmadepay  ! alawdec ! autoaudiosink
    

    solution 2 (Tested)

    Try using mux/demux combination

     `gst-launch-1.0 -e rtspsrc location='rtsp://localhost:554' latency=0 name=d d. ! queue ! capsfilter caps="application/x-rtp,media=video" ! rtph264depay ! mpegtsmux name=mux ! filesink location=file.ts d. ! queue ! capsfilter caps="application/x-rtp,media=audio" ! decodebin ! audioconvert ! audioresample ! lamemp3enc ! mux.`
    

    To decode the pipeline

    gst-launch filesrc location=file.ts ! typefind ! mpegtsdemux name=demux demux. ! queue ! h264parse ! ffdec_h264 ! autovideosink demux. ! queue ! mp3parse ! ffdec_mp3 ! audioconvert ! autoaudiosink demux.

    Solution 3 (Untested)

    Try using a Tee based approach. Also run gst-launch-0.10 -v playbin2 uri=rtsp://192.168.0.20/live1.sdp. Notice the verbose option. This will give you a lot of hints on how to construct the pipeline.

    Have a common source to Tee bin -> fork this into two pipelines one for audio decode and one for video decode.

    src -> tee (fork into two branches - sub pipelines) -> (branch 1 will have audio demux -> audio decoder -> audio sink) and (branch 2 will have video demux -> video decoder -> video sink)

    Give the following a shot (untested). You may have to tweak this pipeline a bit to get it to work but you will get an idea.

    gst-launch rtspsrc location=rtsp://192.168.0.20/live1.sdp ! queue ! tee name=t !\
    rtph264depay t. ! \
    h264parse t. ! capsfilter caps="video/x-h264,width=1280,height=800,framerate=(fraction)25/1" t. ! 
    ffdec_h264 t. ! ffmpegcolorspace t. ! autovideosink t. ! queue ! \
    rtpg726depay !  ffdec_g726 !  audioconvert ! audioresample ! autoaudiosink
