Posted: Fri Jul 25, 2008 10:04 am Post subject: [Asterisk-video] mp4save file format
Hey everyone,
I just installed a new machine with the fontventa applications on Asterisk 1.4.18.1 (rev 222).
On my other machine I have rev 210 running on Asterisk 1.4.17 and mp4save would record in h263/amr file format.
With the new machine however it records the sound into ulaw instead of amr. Is there a way to change this?
Now ->
Track Type Info
1 video H.263, 19.915 secs, 39 kbps, 176x144 @ 9.389907 fps
2 hint Payload H263-1998 for track 1
3 audio G.711 uLaw, 19.940 secs, 64 kbps, 8000 Hz
4 hint Payload PCMU for track 3
Before->
Track Type Info
1 video H.263, 10.210 secs, 43 kbps, 176x144 @ 9.794319 fps
2 hint Payload H263-2000 for track 1
3 audio AMR, 10.320 secs, 13 kbps, 8000 Hz
4 hint Payload AMR for track 3

Hi,
First have you patch your new Asterisk with the AMR support ?
I have propose to force the AMR recording with the 3GP file extension.
I have made a patch for that proposed in this forum.
3GP -> Force AMR recording.
MP4 -> Authorize linear encoding codecs
Extract of the app_mp4.c code source :
/* Lock module */
u = ast_module_user_add(chan);
int length = strlen(data);
if (!strcmp(&data[length - 4], ".3gp"))
{
if (ast_set_read_format(chan, AST_FORMAT_AMRNB))
ast_log(LOG_WARNING, "mp4_save: Unable to set read format to
AMRNB!\n");
}
else
{
if (ast_set_read_format(chan,
AST_FORMAT_ULAW|AST_FORMAT_ALAW|AST_FORMAT_AMRNB))
ast_log(LOG_WARNING, "mp4_save: Unable to set read format to
ULAW|ALAW|AMRNB!\n");
}
/* Send video update */
ast_indicate(chan, AST_CONTROL_VIDUPDATE);
Regards,
Borja

Hey Borja,
I have patched with AMR. After applying your patch (below) and using 3gp as extension the audio recording is now saved as AMR.
Thanks a lot.
Have a nice weekend!
