Hi,
At my company http://www.streamtheworld.com, we have ADTS AAC Plus V2 streams and for some strange reasons, VLC is not able to playback the streams.
Here is an URL of such stream:
http://208.80.52.90/CITFFMAACCMP3
I say strange because if I dump the stream into a .aac file with wget, vlc will play fine the file. If this can help, the mime type returned by our servers is audio/aacp
and winamp is able to play our ADTS AAC streams.
The problem has been observed with 0.9.6 and 0.8.6
Greetings,
ADTS AACPlus V2 streaming problem with VLC 0.9.6

Ok,
I think that the message in my previous post was clear but I'll try one more time...
I think that the operating system is irrelevant but if you insist to know I am using Windows XP. I said that the mime-type returned by the server was "audio/aacp" but to make the message clearer to you, here is the full server reply:

VCL works fine.
It is not a codec problem because if you do:
wget http://208.80.52.90/CITFFMAACCMP3 -O CITFFMAACCMP3.aac (for few seconds)
and open CITFFMAACCMP3.aac with VCL, it plays the file fine.
How to reproduce:
In winamp:
open URL: http://208.80.52.90/CITFFMAACCMP3
It works
In VCL 0.9.6:
open URL http://208.80.52.90/CITFFMAACCMP3
It does not work.
Very easy to reproduce.

Re: ADTS AACPlus V2 streaming problem with VLC 0.9.6
Thank you, this is very useful, because it seems that the VLC is not able to find a correct demuxer when taken from http.
What demuxer is used when dumped on file ?

Re: ADTS AACPlus V2 streaming problem with VLC 0.9.6
This is indeed a bug, since when I do vlc -vvv HTTP:/.... --demux m4a, I have audio for just a couple of seconds...
You have to fill a bug then.

The bug seems to be that VLC cannot demux m4a straight over http... Is it even a spec ?

Re: ADTS AACPlus V2 streaming problem with VLC 0.9.6
Ok thanks. I will log a bug.
This is just an opinion but I think that if a multimedia format has an official mime-type than it should be possible to transport it over HTTP.
I'm just the messenger and ultimately, it is the VLC developers that will need to decide. All I can say is that at my workplace VLC has the reputation to be the most liberal player. Usually, you throw something at it and if it is playable, it will play it.
Greetings,

Re: ADTS AACPlus V2 streaming problem with VLC 0.9.6
J-B,
I went to your trac page, created an account but I do not have the permission to create new bugs because new trac accounts need to be validated by someone from VideoLan.
Is this something that you can do or send an e-mail to someone who can grant me this right?
Otherwise, I'm afraid that someone will need to fill in the bug on my behalf...
My trac username is olanglois.

Re: ADTS AACPlus V2 streaming problem with VLC 0.9.6
This is fixed in 1.0 development.
The issue is that those streams are not answering exactly like normal Icecast streams.

Re: ADTS AACPlus V2 streaming problem with VLC 0.9.6
J-B,
I have checked the code change that you refer in the ticket:2299 and I think that the change is unrelated to the problem that I have reported. The code change is related to shoutcast metadata interval. BUT... I have looked a little bit in the same file and I have seen this:
1381 else if( !strcasecmp( psz, "Server" ) )
1382 {
1383 msg_Dbg( p_access, "Server: %s", p );
1384 if( !strncasecmp( p, "Icecast", 7 ) ||
1385 !strncasecmp( p, "Nanocaster", 10 ) )
1386 {
1387 /* Remember if this is Icecast
1388 * we need to force demux in this case without breaking
1389 * autodetection */
1390
1391 /* Let live 365 streams (nanocaster) piggyback on the icecast
1392 * routine. They look very similar */
1393
1394 p_sys->b_reconnect = true;
1395 p_sys->b_pace_control = false;
1396 p_sys->b_icecast = true;
1397 }
1398 }
The comment about forcing demux for Icecast seems to be related. With the server reply that I have provided, the server name is MediaGateway hence the player will not execute the conditionnal block of code.
As a side note, it looks that this:
1204 /* ICY meta data request */
1205 net_Printf( VLC_OBJECT(p_access), p_sys->fd, pvs, "Icy-MetaData: 1\r\n" );
is a new addition since VLC 0.9.6 does not seem to ask for meta data. The MediaGateway server support meta data like this.
Do you want me to reopen the bug or you will take care of it?

Re: ADTS AACPlus V2 streaming problem with VLC 0.9.6
ok I get it!
If the server accept the metadata request then VLC consider the server as an Icecast server and from there, the demux forcing code kicks in.
If that is the case then everything is good.

Re: ADTS AACPlus V2 streaming problem with VLC 0.9.6
Well, no, the thing is that VLC didn't understood it was an icecast server, so either VLC is not following the spec, or the server is. So this 2-lines patches is MORE laxist, and makes it work with that server...
So when 1.0 is released, this will be fixed.

Re: ADTS AACPlus V2 streaming problem with VLC 0.9.6
J-B,
I have though about the issue overnight and I still think that the player could be improved further.
First the Icecast detection conditions are somewhat brittle. From what I have understood the conditions are:
If server name is Icecast or nanosomething.
The condition value is not much because since Icecast version 2.3.2, the server name is configurable by editing the Icecast XML config file. So in theory, you could have as much different server names than there are Icecast servers on the Internet.
secondly the server is Icecast if it returns an HTTP reply and accept the client shoutcast metadata request. This might not be always true in the future and depending on the multimedia format used by the stream.
I can give you an example. My server is not Icecast. In some aspects, it will behave like Icecast but it does more than Icecast. For instance, my server streams FLV streams. Something that you cannot do with Icecast and since Flash players do not support shoutcast metadata the server will ignore the metadata request. So based VLC would not consider my server as Icecast and demux detection would likely failed.
What I do not understand about VLC logic is why it insist on detecting Icecast to consider the Content-Type reply field. I mean the content could be served by a regular HTTP server and VLC player would not work properly because it is not Icecast. Unless someone explain me, it does not make much sense!
My suggestion is that the player should consider the Content-Type no matter what type of server is replying. In my opinion, the Content-Type is as valuable as filename extension. That would make your player much more robust.

Re: ADTS AACPlus V2 streaming problem with VLC 0.9.6
It is simple: Content-Type is not reliable for a lot of servers (file servers).
In the general case, our internal demuxer detection code works better.
On the other end, with icecast/streaming server, the first frame sent is often broken (start in the middle), while Content-Type is always right.
So we use Content-Type only when we can detect that its value is reliable.
Do you know a better way than checking on icy-meta to detect icecast-like server when it does not use ICY protocol ?

Re: ADTS AACPlus V2 streaming problem with VLC 0.9.6
Cool,
thank you for the explanation. I didn't know that HTTP server content-type was not reliable. Probably that very often the generic "application/octet-stream" mime-type is returned. I guess that there is no ideal solution then.
One way that you could improve the detection is if you look for any reply header field starting with "icy-". This might not catch all cases but certainly it would be more general than just checking specifically for "icy-metaint".
Keep up the good work!
I'm not saying no for some code contribution eventually but I do not want to take commitments now on something that I am not sure to have time to deliver as I am very busy on plenty of other things...
