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....</blockquote><div><br>
one more guess: <br>
1) is vlc able to successfully encode amr_wb to a file (instead of streaming) ?<br>
2) if so, can QTPlayer (or any other player) play this file ?<br>
3) if so, then my guess is that vlc does not properly apply the amr_wb
(sawb) encoded content to the rtp stream. That was the reason for
amr_nb (samr) not working when I tried it about 4 months ago. VLC
Developers told me that the packetize_amr (in
<a href="https://trac.videolan.org/vlc/file/trunk/modules/stream_out/rtp.c">https://trac.videolan.org/vlc/file/trunk/modules/stream_out/rtp.c</a>)
function does not work properly. It is described in RFC3267
(<a href="http://www.apps.ietf.org/rfc/rfc3267.html#sec-4">http://www.apps.ietf.org/rfc/rfc3267.html#sec-4</a>) how to implement it.
That's where I gave up... <br>
<br>
Maybe some VLC developer can help implement the amr packetizer for rtp?<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 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">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

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">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>
