[vlc-devel] mp4 file no sound on iPhone

[Jean-Romain]

Hi,

I ran into this issue.
It's due to bugs in VLC and in Apple's players.
Here is a trail of my research on the subject, since I've not yet been able to get to work with only one VLC command I've posted this on superuser to save it and hoping someone could help be finish.

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!
