[gst-devel] FW: ffmux_asf Query

[Irfan Shaikh]

Hi ved,

	As per ur suggestions i hav been trying to use ffmux_asf. 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.

Regards,
Irfan

HI,

Is the dat file elementary stream or some container format?. 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.
