Question

我正在尝试将flv流转换为另一个mp3或ogg流。关键是我想在HTML5页面上使用mp3 / ogg流，因为flv流不能用HTML5播放。所以，我配置了avserver.conf：

Port 8090
BindAddress 0.0.0.0
MaxHTTPConnections 2000
MaxClients 1000
MaxBandwidth 1000
CustomLog -

<Feed feed1.ffm>
    File /tmp/feed1.ffm
    FileMaxSize 200K
    ACL allow 127.0.0.1
</Feed>

<Stream test1.ogg>
    Feed feed1.ffm
    Format ogg
    AudioBitRate 64
    AudioChannels 1
    AudioSampleRate 44100
    NoVideo
</Stream>

<Stream stat.html>
    ACL allow localhost
    ACL allow 192.168.0.0 192.168.255.255
</Stream>

<Redirect index.html>
    URL http://www.libav.org/
</Redirect>

我使用的命令：

avconv -i http://some_stream_service?format=flv -acodec mp3 http://localhost:8090/feed1.ffm

控制台输出：

它看似有效，但我在网页http://localhost:8090/test1.ogg上不断获得0个字节。有没有人知道我做错了什么？

使用avconv将流转换为流
