Hi all, I had used the mp4play and mp4save applications in Asterisk 1.4.21.2.
Recently I had downloaded the above mentioned (1.4.26) version from Asterisk
website and installed it together with the MP4 application package. However,
when i try to use the save function, if there is no audio, it creates the file
though there is no sound heard when i play it in vlc. But, when I use video, it
produces teh following error message and the file created will contain video. I
used mp4info to check the type of content.

I am using Linphone. I used ulaw and h263+ codecs. Are there issues related to
sound with mp4 application and also with Asterisk version 1.4.26? Please advice
me what to do. Even when i record audio only I get no sound while the status
bar is moving in VLC.
Thank you.
