Can you share the way you do to test the library , any online free streaming server or any pc software ?
Sorry, i can´t really help on this. I just wrote the wrap and was using the wowza server from a tester to test it.

https://www.wowza.com/products/streaming-engine

the wowza streaming-engine server for example is a windows software to download. I never configured a wowza server.

how to enable the audio?
set the audioencode to 3 or 5... (See Example-Code in post #1)
/** Can be used with {@link #setAudioEncoder}. */
public final static int AUDIO_NONE = 0;
/** Can be used with {@link #setAudioEncoder}. */
public final static int AUDIO_AMRNB = 3;
/** Can be used with {@link #setAudioEncoder}. */
public final static int AUDIO_AAC = 5
;

Dear Expert,

How to know another parameters value not just int 1 for setVideoEncoder?

thx

You can use any static names for them...

B4X:
/** Can be used with {@link #setVideoEncoder}. */
    public final static int VIDEO_NONE = 0;

    /** Can be used with {@link #setVideoEncoder}. */
    public final static int VIDEO_H264 = 1;

    /** Can be used with {@link #setVideoEncoder}. */
    public final static int VIDEO_H263 = 2;

B4X:
dim VIDEO_NONE as int = 0
dim VIDEO_H264  as int = 1
dim  VIDEO_H263 as int = 2

Hi.
Is any way to stream audio only like the official Wowza app do???
I need to stream audio only, no video needed.
Thanks a lot in advance.

Did you tried all variants of

setAudioEncoder (encoder As Int) As SessionBuilderWrapper
Sets the audio encoder.

One of the AudioEncode is NONE i guess... Did not use the lib a long time

Edit:

/** Can be used with {@link #setAudioEncoder}. */
public final static int AUDIO_NONE = 0;

/** Can be used with {@link #setAudioEncoder}. */
public final static int AUDIO_AMRNB = 3;

/** Can be used with {@link #setAudioEncoder}. */
public final static int AUDIO_AAC = 5;

Hi Don, i have a problem with your wrap.
When i connect to my RTSP server, it writes this messages:

2020/04/17 17:38:58 [RTSP client 192.168.8.100:40380] connected
2020/04/17 17:38:58 [RTSP client 192.168.8.100:40380] ANNOUNCE
2020/04/17 17:38:58 [RTSP client 192.168.8.100:40380] SETUP
2020/04/17 17:38:58 [RTSP client 192.168.8.100:40380] ERR: transport header does not contain mode=record
2020/04/17 17:38:58 [RTSP client 192.168.8.100:40380] disconnected

How can i set the trasport header with mode=record ?

Thank you!
Roberto

I think the original libStreaming project on GitHub was discontinued quite some time ago.
For your information, I will be releasing a library shortly which supports initially only RTMP but I will probably add RTSP to it as well.
When released, I will announce it here in the forum.
