ffmpegを使ってデスクトップ画面をテレビのブラウザにストリーミングしようとしているので、ここにCLIがあります
./ffmpeg -probesize 1000M -framerate 60 -video_size 1680x1050 -f x11grab -i :0.0 -f alsa -i default -c:a aac -c:v libx264 http://localhost:8090/feed1.ffm
そしてこれが私のffserver.conf
<Stream h264>
Format webm
Feed feed1.ffm
VideoCodec libx264
VideoFrameRate 24
VideoBitRate 100
VideoSize 480x272
#AVPresetVideo default
#AVPresetVideo baseline
AVOptionVideo profile main
PixelFormat yuv420p
#
AudioCodec aac
AudioBitRate 32
AudioChannels 2
AudioSampleRate 22050
AVOptionAudio flags +global_header
</Stream>
そして、私が得ているエラーはこれです

それで、私は何を間違っているのでしょうか?
