the mobile tries to load the stream (instead of telling you that this

issue...<br>
One thing to test if aac is supported at all might be:<br>
1) encode a video with mp4/aac using vlc<br>
2) hint the encoded file with mp4box and put it in DSS' streaming
dir<br>
3) access the encoded file directly without using an sdp file (e.g.
<a href="rtsp://server:port/myfile.mp4">rtsp://server:port/myfile.mp4</a>)
to see if aac sound works.<br>
==> If it does not work, i bet it's the phone not soppurting aac. Then
we are sure that there's nothing wrong with the sdp (because it's not
involved here) and it's also not the fault of VLC's mp4a packetizer
(because this one is not involved when VLC encodes to file)<br>
==> On the other hand, if it works, then there must be something wrong
with either the sdp or the packetize_mp4a method -- or something
completely different :-/</blockquote><br>
I encoded a mp4/aac file, and hinted it with mp4creator , and sound is
not working. For this one, i think its a DSS issue, because the
sample_100kbit.mp4 (with aac) doesn't work either with DSS.<br>
I'm trying to find a streaming server that can stream mp4/aac to mobile
phones.<br><br>
<blockquote type=cite class=cite cite><blockquote type=cite class=cite cite>when
playing with the sdp file,i can make my mobile phone loading my aac
stream, but not playing it (player stuck at the end of
loading).</blockquote><br>
Unfortunately I can't test the stream right now, because my current
provider does not allow any other traffic than http :(<br><br>
<blockquote type=cite class=cite cite>looking at the code of the rtp
module, i noticed amr / mpa4 sections seems inappropriate for mobile
streaming (looks normal). unfortunatly i'm not able to implement such
thing. Maybe i'm completely wrong ...<br>
correct me in this case.</blockquote><br><br>

<blockquote type=cite class=cite cite>Well,<br>
back again !<br>
streaming amr_wb is the same as amr_nb.. it doesn't play in QTplayer
because it doesn't have the codecs, but the mobile player seems to accept
it, but no sound is coming.<br>
switch back to amr_nb and play with the sdp file....<br><br>

<blockquote type=cite class=cite cite>I came to the same conclusion as
you .<br>
For now, i'm working on the sdp stuff which i think is the problem. Or it
might be the reflector module of DSS (in this case i doubt i could do
anything for it).<br><br>

I talked on irc with some guys, and it seems that it's not very possible

as i want to take an already running stream and transcode it to 3gp , i
think i cannot do that with opensource or free software.
</blockquote><br>
I think it is possible with vlc+dss, as soon as the sound issue is
solved. Even though the stream might not be 100% 3gp spec compliant, it
worked (at least with video only). <br><br>
<blockquote type=cite class=cite cite>I noticed that DSS is not able to
stream mp4+aac to mobile phone -> nokia 6630 , sound is not working,
even with the sample which comes with the server. Making aac streaming
working on the mobile would be the solution.(amr is not my
preference).</blockquote><br>
I think that's not possible with the 6630, because it can not play aac
streams :( <br>
On the other hand DSS _is able_ to stream mp4+aac (as you can see the
stream with different players, such as QT), so imho it is definitely the
mobile, which is _not able_ to play rtsp-streamed aac.<br>
But you are right, amr_nb is no solution because it is too crappy...
amr_wb might be okay, even though not as good as aac.<br><br>
<blockquote type=cite class=cite cite>if you know a streaming server that
can do that.. pls tell me.<br>
maybe tomorrow i will try amr_wb . i will keep you informed.<br><br>
NB : 3gp or mp4 generated by vlc doesn't play on the mobile phone on
local playback (possibly beacause of the lack of hinted
tracks)</blockquote><br>
Right, for local playback you need to hint the files. I used mp4box for
hinting and got it work to play locally with mp4+aac and mp4+amr (both
encoded with vlc). Don't remember if it worked with h263 video too, but i
guess so.<br><br>
Good luck with the amr_wb
stuff!</blockquote></blockquote></blockquote></blockquote></blockquote></blockquote></body>
