[gst-devel] ffmux_asf Query

[ved kpl]

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.
