ffserver-2.2 - 在 Debian 7.5 上使用 ffserver 将 ASF 视频流式传输为 OGG 输出

我正在尝试将 IP 网络摄像头 ASF 实时流传输到 ffserver 以输出 OGG 格式。服务器成功启动，但用于向 ffserver 提供数据的 ffserver 命令因段错误而失败。

输入流

$ ffprobe http://account:password@webcam/videostream.asf

Input #0, asf, from 'http://account:password@webcam/videostream.asf':
  Duration: N/A, start: 0.000000, bitrate: 32 kb/s
    Stream #0:0: Video: mjpeg (MJPG / 0x47504A4D), yuvj422p(pc), 640x480, 25 tbr, 1k tbn, 1k tbc
    Stream #0:1: Audio: adpcm_ima_wav ([17][0][0][0] / 0x0011), 8000 Hz, 1 channels, s16p, 32 kb/s

ffmpeg 提要

我运行以下命令失败

$ ffmpeg  -i http://account:password@webcam/videostream.asf http://ffserver_ip:port/webcam.ffm

这对我来说没有音频

<Feed cam1.ffm> File /tmp/cam1.ffm FileMaxSize 10000K ACL allow 127.0.0.1 </Feed>

<Stream vid.ogg> Feed cam1.ffm Format ogg VideoCodec libtheora VideoFrameRate 15 VideoSize vga VideoBitRate 320 VideoBufferSize 40 VideoGopSize 12 VideoQMin 1 VideoQMax 31 Preroll 0 AVOptionVideo flags +global_header NoAudio StartSendOnKey </Stream>

重新加载我的服务器

ffserver -f /etc/ffserver.conf reload

开始我的订阅

ffmpeg -f alsa -i default -f video4linux2 -i /dev/video0 http://localhost:8888/cam1.ffm

从 html 播放视频流

<video controls>
    <source src="http://192.168.1.104:8888/vid.ogg" type="video/ogg">
     Your browser does not support the <code>video</code> element.
