Thanks for the reply.<br>1. Please tell me how to convert mpeg4-generic encoded audio data to PCMU encoded audio data in .mp4 file. I tried with ffmpeg, but couldn't succeed.<br>2. If you have any mp4 file with PCMU sound track, please share with me.<br>
3. Does freeswitch comes with mpeg4-generic codec support?<br><br><br>Thanks & Regards,<br>Muqtheear.S<br><br><div class="gmail_quote">On Thu, Jan 10, 2013 at 4:59 AM, Seven Du <span dir="ltr"><<a href="mailto:dujinfang@gmail.com" target="_blank">dujinfang@gmail.com</a>></span> wrote:<br>

Sorry, for the sound track, I guess you need convert to PCMU, if I remember right, the last time I look the code it said only PCMU is supported.

<span><div><div><pre>mod_mp4 module is looking for Hint tracks in the .mp4 file.
"Hint tracks are a series of instructions in a mp4 container file that
tell a server how to transmit packets."
To create hint tracks for a mp4 file is fairly simple with the mp4creator
program, we just executed the:
mp4creator -hint=<track to hint track number> [-p <payload>] <mp4file>
As we know .mp4 has both video+audio data in it. We could also find audio
and video encoding information of a .mp4 file as shown below.
#mp4info minnale.mp4
mp4info version 1.5.0.1
minnale.mp4:
Track Type Info
1 video MPEG-4 Simple @ L1, 97.833 secs, 136 kbps, 176x144 @
12.000041 fps
2 audio MPEG-4 AAC LC, 97.568 secs, 64 kbps, 32000 Hz
3 hint Payload MP4V-ES for track 1
4 hint Payload mpeg4-generic for track 2
Metadata Tool: mp4creator 1.6
Now we are getting "Invalid codec mpeg4-generic!" error.
Please guide me. Do we need to have mpeg4-generic codec in Freeswitch server?<br><br><br>Thanks & Regards,<br>Muqtheear.S</pre>
