I tried to mux a mpeg2-ts file with h264video and aac audio.
I used the mpegtsmux in gst-plugin-bad-0.10.9.

My pipeline is this :
gst-launch -v --gst-debug-level=$dbg \
        filesrc location=davincieffect_ntsc.264  \
        ! h264parse ! mux. \
        filesrc location=davincieffect.aac ! aacparse ! mux. \
        mpegtsmux name=mux \
        ! filesink location=out_264_for_6446.ts

When I played the ts file using mplayer, 
Only video can be seen.
Audio is missing.

The following is  messages from Mplayer:

Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.

FAAD: Failed to initialize the decoder!
ADecoder init failed :(
ADecoder init failed :(
