RTSP Streaming to AMINET 110

Postby __mami » 25 Mar 2006 11:04

As we have understood till now:

VLC can not be used as a RTSP server for amino AMINET Devices, bacause they use their special kind of RTSP implementation.

RTSP uses mainly RTP for transferring the video stream but AMINET uses RTSP along with UDP for transferring the video.

I know VLC uses LIVE555.com package for RTSP Implementation.

Now my question:
live555.com claims that it fully supports AMINET devices and as far as I understood there are many successful cases for this.
VLC is based on live555. then, why VLC is not able to serve AMINET correctly?

OK!
no reply?

I tested it personally,
I made a MPEG2 Transport stream, then I gave it to LIVE555 example program and it could successfully communicate with aminet.

Again i gave the same ts to vlc, and i did all of the needed configurations, i tested my config using another vlc connecting to my first vlc via rtsp and every thing was ok. but when i try to get the stream using aminet nothing happens.

i think that a very small change is needed in the source code of vlc so that every thing work correctly.

To stream to the amino net box you have to put on your address link igmp://239.255.0.0.0:0000 and it should see the Vln stream. Remember that your VLN steam set up depending on what you are doing if you have it to stream to the amino net box directly you have to set up a udp stream. If you are having the amino net box listen for the stream from the Vln server its a Mulitiplex stream. Unless you know what you are doing its no easy to get into th amino box to change the IP adress that set up by default. I suggest just doing the muliplex stream. It took me a long time to get on to work. Hope that helps

What????

I'm talking about RTSP streaming and VOD.

What????

I'm talking about RTSP streaming and VOD.
I have written a patch to permit VLC to be used as a RTSP VOD server for Amino STBs which can be downloaded from the vlc-devel mailing list archive at http://www.via.ecp.fr/via/ml/vlc-devel/ ... 00544.html - The changes associated with this patch are to modify the command sequence response header (from "Cseq" to "CSeq"), add command-line support to set the mux for raw UDP streams and add support for the RTSP GET_PARAMETER command.

It's work :)
Compile vlc from subversion and start like this:
vlc --rtsp-host 0.0.0.0:554 --rtsp-raw-mux=ts --ttl 12 -vvv --color -I telnet

then:
telnet 127.0.0.1 4212
> new test vod enabled
> setup test input /mpeg2l.m2t

and then on amino 110:
type=VOD;servertype=MediaBase;src=rtsp://10.1.2.6:554//10.1.2.6/test

request is seems like:

OK! So I see, finally the problem is solved,

what about jump, fast forward, rewind and so ... are any of these supperted?

As I remember LIVE555 does not currently support these options, it just supports pause, but no for example to jump from one location of video to another.

Play and pause are currently supported, and while the Amino STB will happily send through a PLAY command with a Scale header for fast-forward or rewind action, this header is currently ignored by the VLC RTSP server interface. I am intending to investigate this further once I have time to do so. Likewise position jumping is not supported currently through the VLC RTSP server interface (although can be achieved through the RC interface for active streams).

So,
For adding the jump feature ( and rewind ) we can use RC or Telnet interface. yes?

The video is sent to AMINET using RTSP, and pause is managed by RTSP. for other actions like, stop, jump and rewind, we should develope the needed codes for managin telnet or rc interfaces. correct?

Now, I'm wondering about AMINET side. As you know, when you press a key of the remote control for aminet, the pressed key can be obtained using a java script. ( the script which is running under Ant Fresco ) now, I'm wondering what will happen when you are sending the video through RTSP, will you still be able to capture the pressed key, or may be, this process will be done completely by the RTSP related code in AMINET.

Here is some html code you could play with allowing the user to press
buttons and then examine the code send to RTSP routines:

<script language="javascript">
function keyAction(e) {
var keypressed = e.which;
switch(keypressed)
{
case 1073742136: // Pause
AVMedia.Pause();
break;
case 1073742131: // Play
AVMedia.Continue();
break;
case 1073742132: // FF
AVMedia.SetSpeed(10);
break;
case 1073742134: // Rewind
AVMedia.SetSpeed(-10);
break;
case 1073742133: // Stop
AVMedia.Kill();
break;
default:
// un-comment this statement to determine teh key codes for additional keys
alert("unhandled key press: "+keypressed);
break;
}
}
</script>

Hi RichC,
Do you have more examples on the javascript that the Fresco browseer uses on the Aminet boxes?

VLC 0.8.6-svn (rev. 15380) can't start TELNET interface

Postby Paul Yarkov » 17 Jan 2007 16:41

I try to compile 0.8.6-svn (rev. 15380) with lastest CygWin under Win2k. This revision has patch for Aminet 110 by Rob Casey. I am badly need for it. So I use contrib-20060428-win32-bin-gcc-3.4.5-only.tar.bz2 and cygwin-compile.txt recomendations. Compilation was almost normal exclude some warnings. But then I run vlc.exe from command-line:
vlc --rtsp-host 0.0.0.0:554 --rtsp-raw-mux=ts --ttl 12 -vvv --color -I telnet
program is "drop" and
telnet localhost 4212
command has no effect and write about connection error.
Any ideas?
PS. Excuse me for my bad English.

Compile vlc from subversion and start like this:
can you paste your configure line? what was enabled... i try to make my own too.

Is there any further progress on this? Does VLC support RTSP trick-play on AmiNET 110? Thanks! 8)
Of course, that's just my opinion. I could be wrong.
