[FFmpeg-user] How to use ffserver to provide a valid source for Window Media Services 2008

[曾若瑜]

Hi,

I'm using ffserver (ffmpeg 2.2.2) with this config

----------------------------------------------

<Stream qtstar.asf>

Feed feed1.ffm

Format asf

NoVideo

AudioCodec wmav2

AudioChannels 2

AudioBitRate 128

AudioSampleRate 44100

StartSendOnKey

AVOptionAudio flags +global_header

</Stream>

----------------------------------------------

Then I ran ffmpeg

ffmpeg -loglevel debug -i <some_live_source> http://localhost:8090/feed1.ffm

Everything seems OK with stats:

Now I met two problems here:

* The ASF stream is NOT a valid source for Windows Media Services
Error Description: The server is not a compatible streaming media server.
Error Code: 0xc00d2ee8

* When I try to play it with ffplay, outputs contains warnings like these:

Does this mean I can only generate a valid source for WMS 2008 with Windows
Media Encoder?
