[Asterisk-video] app_mp4 -- need help

[Wu Ui Kok]

hi

I have successfully compiled app_mp4. I can record and play mp4 ( thanks
sergio :) ).  the problem is I got warning as below:

Dec 21 12:28:20 WARNING[5765]: chan_sip.c:2572 sip_write: Asked to transmit
frame type 4, while native formats is 524288 (read/write = 0/0)
Dec 21 12:28:20 WARNING[5765]: chan_sip.c:2572 sip_write: Asked to transmit
frame type 4, while native formats is 524288 (read/write = 0/0)
Dec 21 12:28:20 WARNING[5765]: chan_sip.c:2572 sip_write: Asked to transmit
frame type 4, while native formats is 524288 (read/write = 0/0)
MP4ERROR: MP4Array::[]: index 28 of 28: Numerical result out of range
MP4ERROR: MP4Array::[]: index 28 of 28: Numerical result out of range
  == Auto fallthrough, channel 'SIP/herman-1ed04ad8' status is 'UNKNOWN'

this warning keep came out during playing the mp4 file and the SIP Client
hung up automatically , which I believed mp4 file finished play. is this
normal?

in my extensions.conf  like this :

[sip]
Exten => 100,1,Answer
Exten => 100,2,Wait(2)
Exten => 100,3,mp4save()

Exten => 200,1,Answer
Exten => 200,2,Wait(2)
Exten => 200,3,mp4play()

thank you
