I hav been looking into the source code of ffmpegs muxer code. I have been trying to mux the videotestsrc and audiotestsrc using ffmux_asf. but i am not able to get any output file. Will you please help to achieve o/p ASF file. I used,         gst-launch audiotestsrc ! ffenc_g726 ! queue ! mux.audio_0 videotestsrc ! ffdec_mpeg4 ! queue ! mux.video_0 ffmux_asf name=mux ! filesink location=/root/Desktop/vidaud.asf This is also not working, Please help me regarding this pipeline if this works i fine i will be half way through, Since i can conclude if i use appropiate encoders for file formats needs to be supported ffmux_asf can work properly. Will finish going through the source code by Evening so as to be more clear about ffmux_asf plug-in.

If its just an elementary stream then u need a parse ( h264parse) in between.  (filesrc ! 'video/x-h264' ! h264parse ! ... ) . But then its  a DAT file, so probably you need to strip off the unwanted bytes in it before giving it to h264parse. ffmux_asf , guess does not take h264 so add h264 decoder and supported encoder also. What mpeg4 data does mpeg4_mp3.asf have? Check the formats that ffmux_asf supports.
