Hi:

In my current project, I am recording some video files from a DirectShow camera-----saved the file as mp4-----they can play pretty well on PC and Android. But on iPhone, there is no sound at all! only the picture!

the VLC command I use is:

:sout=#duplicate{dst=display,dst=\'transcode{venc=x264{keyint=15,bframes=0},vcodec=h264,vb=200,scale=1,fps=15,acodec=mp3,ab=128,channels=2,samplerate=44100}:std{access=file,mux=mp4,dst=xxxx.mp4


I have tried to change the command line as below but still no sound, the same phenomenon...

:sout=#duplicate{dst=display,dst=\'transcode{venc=x264{keyint=15,bframes=0},vcodec=h264,vb=200,scale=1,fps=15,acodec=mp4a,ab=128,channels=2,samplerate=44100}:std{access=file,mux=mp4,dst=xxxx.mp4

Does anyone know what the problem is and how to solve it? Many thanks!
