我怎样才能让 ffserver 工作?

我有一个 mp4 文件,希望对其进行压缩、调整大小并通过 RTSP 进行流式传输。

我的 ffserver.conf 文件如下所示:

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>

据我所知,我不需要使用 ffmpeg 输入视频流,因为我正在使用 File 属性,所以 ffserver 可以为我完成这项工作?

当我尝试使用 totem 播放视频(ffplay 超时)时,出现以下错误:

$ 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 的日志如下所示:

我究竟做错了什么?

您可以使用 gstreamer 实现调整大小、重新编码为 mpeg2 和 RTSP 流,但我无法更改帧速率。如果这足够了,请按照以下步骤操作:

  • 安装gst RTSP服务器开发包:sudo apt-get install libgstrtspserver-0.10-dev
  • 获取副本此示例启动器
  • 使用以下方法编译gcc -o test-launch $(pkg-config --cflags --libs gstreamer-0.10 gst-rtsp-server-0.10) test-launch.c
  • 开始流式传输:./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 )"
  • 看视频:gst-launch-0.10 rtspsrc location=rtsp://127.0.0.1:8554/test ! decodebin ! xvimagesink

一些注意事项:

  • 要更改端口,您必须gst_rtsp_server_set_port(server, 9091);在 test-launch.c 中的第 44 行和第 45 行之间添加一个调用
  • totem 读取流,但不显示任何内容,甚至不显示错误消息
  • mplayer 不支持流类型
