[Asterisk-video] MP4 Application not working in 1.4.26

[Zelalem Sintayehu]

Hi Hemanshu, thank you for your response. I think the application doesn't work with h264. I allowed h263 and/or h263+. But even in the absence of video, it creates the file (with ulaw codec) but I can hear nothing when i play the file using VLC. What could be the reason?

Regards,

allow=h264
allow=ulaw

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.
