I use VLC to record Webcam+Microphone into mp4 files.My transcode:
:sout=#transcode{vcodec=h264,vb=512,scale=0.5,acodec=mp4a,ab=128,channels=2}:duplicate{dst=std{access=file,mux=mp4,dst="D:\Program Files\VideoLAN\VLC\demo.mp4"}}
But when i play the recorded file,I found video is play faster than audio(audio is normal). VLC version is 1.02 . Then i use VLC 0.86i do the same job. the record file is play normal.What is problem?

This is a known issue with the MP4 container in v1.0.x serie. See ticket #2715.
You can remux your MP4 file with MP4Box (a part of the GPAC project) to create a new working MP4 container.
On Windows this can be easily done with YAMB as a GUI. Latest binary of MP4Box for Windows can be found here.

Thanks you for your reply.
