Nobody is able to answer your question because it is underspecified. Also there is no easy answer to your question, you are asking people how to write a multimedia streaming server. Anyway, I'll start with the possibilities and give you an idea on how to implement them. First use case is where we assume the asf file is already available on the server. This can be, for example, achieved by transcoding (google gentrans for a gstreamer based transcoder) and uploading an asf file to the streaming server. - stream asf over http: Install a webserver, upload the file, stream the file with http. No GStreamer involved here although you could write a custom web module that hands a file descriptor to a gstreamer pipeline that uses fdsink to stream to the client. I believe flumotion has code for this in the proprietary extensions. - stream asf over mms. This is basically writing a custom mms server, documents on how mms works can be found on the internets although my experience is that most documents are not very accurate. There is no code in GStreamer that you can reuse for this task. I'm also not aware of an open source implementation of such a server. I would not recommend walking this path, microsoft is discontinuing mms in favour of rtsp. - stream asf over rtsp. You'll need to write an RTSP server that configures the gstreamer transport pipeline. You'll also need to write an asf payloader both for udp and tcp transports. A document on how an rtsp server would work in gstreamer can be found here: http://webcvs.freedesktop.org/gstreamer/gst-plugins-good/gst/rtsp/README?revision=1.5&view=markup There are a bunch of helper libraries in the gstreamer plugins base module that can assist you in creating and parsing RTSP messages, SDP messages and RTP packets. Second use case would be when you need to transcode or encode into an asf stream on the fly. We're talking about live capture or live transcoding. For this you will need wma/wmv encoders and a good asf muxer. ffmux_asf is not a good muxer, I would not use it. I understand Fluendo can provide these encoders and muxers to you. Again I would recommend using either a http server or an rtsp server to prepare the gstreamer transcoding/encoding pipelines.

Hi all,
I am trying to mux the various audio/video elementry streams using ffmux_asf. I used following pipeline. 1)gst-launch filesrc location=/root/Desktop/teststreams/mpeg4/mpeg4_mp3.ASF ! ffdemux_asf name=demux demux.audio_ 00 ! queue ! mux.audio_0 demux.video_00 ! queue ! mux.video_0 ffmux_asf name=mux ! filesink location=/root/Desktop/test2.asf ffmpeg (FFmpeg MJPEG decoder) mp3lib (mp3lib MPEG layer-2, layer-3 2)gst-launch audiotestsrc ! ffenc_mp3 ! queue ! mux.audio_0 videotestsrc ! ffenc_mpeg4 ! queue ! mux.video_0 ffmux_asf name=mux ! filesink location=/root/Desktop/Muxed.asf 3)gst-launch filesrc location=/root/Desktop/teststreams/mpeg4/mpeg4_wma.ASF ! ffdemux_asf ! ffmux_asf ! filesink location=/root/Desktop/test4.asf ffmpeg (FFmpeg M$ MPEG-4 v2) ffmpeg (DivX audio v2 (FFmpeg)) I think there is something wrong in my pipeline structure. Can any one help me to find out how does ffmux_asf works for both audo, video elementry streams {videotestsrc and audiotestsrc}. I would be very thankful to you all if u explaing me with videotestsrc and audiotestsrc how does ffmux_asf works. Regards, Irfan.
