How can I get ffserver to work?

  • 772

I have a mp4 file which I wish to compress, resize and stream via RTSP.

My ffserver.conf file looks like this:

Port 9091
RTSPPort 5454
BindAddress 0.0.0.0
MaxHTTPConnections 2000
MaxClients 1000
MaxBandwidth 1000
CustomLog -
NoDaemon



<Feed feed1.ffm>
 File /tmp/feed1.ffm
 FileMaxSize 500M
</Feed>



<Stream live.mpeg>
 Format rtp
 File "/tmp/rtp.mp4"
 Feed feed1.ffm
 VideoCodec mpeg2video
 VideoFrameRate 15
 VideoBitRate 200
 VideoSize 400x320
 #AudioCodec mp2
 #AudioBitRate 32
 #AudioChannels 2
 #AudioSampleRate 22050
 NoAudio
 #Preroll 10
 ACL allow 127.0.0.1
</Stream>



<Stream stat.html>
 Format status
 # Only allow local people to get the status
 ACL allow localhost
 ACL allow 192.168.0.0 192.168.255.255
</Stream>

From what I understand, I don't need to feed in a video stream using ffmpeg as I am using the File attribute, so ffserver does the work for me?

When I try to use totem to playback the video (ffplay just times-out), I get the following error:

$ totem rtsp://127.0.0.1:5454/live.mpeg
** Message: Error: Could not read from resource.
gstrtspsrc.c(4408): gst_rtspsrc_send (): /GstPlayBin2:play/GstURIDecodeBin:uridecodebin0/GstRTSPSrc:source:
Got error response: 454 (Session Not Found).

ffserver's log looks like this:

What am I doing wrong?

  1. You can achieve resizing, re-encoding to mpeg2 and RTSP streaming with gstreamer, but I didn't manage to change the frame rate. If this is sufficient, here's how:

    • Install gst RTSP server development package: sudo apt-get install libgstrtspserver-0.10-dev
    • Get a copy of this example launcher
    • Compile it with gcc -o test-launch $(pkg-config --cflags --libs gstreamer-0.10 gst-rtsp-server-0.10) test-launch.c
    • Start streaming: ./test-launch "( filesrc location=/tmp/rtp.mp4 ! decodebin ! videoscale ! video/x-raw-yuv,width=400,height=320 ! ffenc_mpeg2video ! mpegtsmux ! rtpmp2tpay name=pay0 pt=96 )"
    • Watch video: gst-launch-0.10 rtspsrc location=rtsp://127.0.0.1:8554/test ! decodebin ! xvimagesink

    A few caveats:

    • to change the port, you have to add a call to gst_rtsp_server_set_port(server, 9091); in test-launch.c, between lines 44 and 45
    • totem reads the stream, but does not display anything, not even error messages
    • mplayer does not support the stream type
