srthaishinkit.swift's Issues

Can't add the package

Describe the bug
When I try to put the package in the package dependencies, and try to compile it says

"Failed to resolve dependencies Dependencies could not be resolved because root depends on 'srthaishinkit.swift' 0.1.2..<1.0.0.
'srthaishinkit.swift' >= 0.1.2 cannot be used because no versions of 'srthaishinkit.swift' match the requirement 0.1.3..<1.0.0 and package 'srthaishinkit.swift' is required using a stable-version but ' srthaishinkit.swift' depends on an unstable-version package 'haishinkit.swift'."

To Reproduce
Steps to reproduce the behavior:

Click on "File"
"Add Packages..."
Enter the package url on the top right "https://github.com/shogo4405/SRTHaishinKit.swift"
Default settings for Dependency Rule "Up to Next Major Version: 0.1.2<1.0.0")
Click on "Add Package"

Expected behavior
When I add the package, it doesn't give dependency issues

Two way connections

In SRTConnection two srt sockets are established when calling SRTConnection.connect(:).

From SRTConnection.swift:31:

outgoingSocket = SRTOutgoingSocket()
outgoingSocket?.delegate = self
((try? outgoingSocket?.connect(addr, options: options)) as ()??)

incomingSocket = SRTIncomingSocket()
incomingSocket?.delegate = self
((try? incomingSocket?.connect(addr, options: options)) as ()??)

My question is: is this specific for a server you (@shogo4405) are working with, or is this part of the srt protocol, as I have not been able to find any mention of this in the srt documentation or srt sample code.

connect method is not available

I have installed the framework but it says there is not method called connect.

Connecting to srt-live-server v1.4.x or ffplay endpoint fails/disconnect

Describe the bug
A clear and concise description of what the bug is.

When using the Example iOS app on a physical iPhone 8(14.4), connecting to srt-live-server results in a socket connection but immediate disconnect.

To Reproduce
Steps to reproduce the behavior:

run srt-live-server locally(on ZeroTier VPN) on mac with this config:

srt {                #SRT
    worker_threads  1;
    worker_connections 300 ;
		
    log_file logs/error.log ; 
    log_level info;
    
    #stat_post_url http://192.168.31.106:8001/sls/stat;

    #vod  file name: /tmp/mov/sls/$listen/$domain_publisher/$app_publisher/$stream_name/vod.m3u8
         
    server {
        listen 3000; 
        latency 200; #ms

        domain_player output;

        app {
            app_player live ;           
            app_publisher live ;

            #relay {
            #    type pull;
            #    mode loop;#loop; hash;
            #    reconnect_interval 10;
            #    idle_streams_timeout -1;#s -1: unlimited

            #}
            #relay {
            #    type push;
            #    mode all; #all; hash
            #    reconnect_interval 10;
            #    idle_streams_timeout 10;#s -1: unlimited
            #    upstreams 192.168.31.106:8080?streamid=uplive.sls.com/live ;
            #}          
        }
    }
}

run Example iOS app with this connection string:

    var url: String = "srt://172.27.125.195:3000?streamid=input/live/iphone8"

Adding Framework to project

Hi, I'm wondering how I add the SRTHaishinKit framework to my current xcode project. I didn't see a cocoapods for it so I wasn't sure how I have to add it in.
-Thanks

How to compile SRT packages to xcode？

hai：
I used the build-srt-iOS.sh script to compile the srt library, but all failed. The libsrt.a library has not been compiled. Can you talk about the compilation steps?
thank！

Connection setup failure: connection time out

I can build this project successfully, but when I run in my iphone device ,
I click the button to push stream then I can see some errors in log;

[Error] [com.haishinkit.SRTHaishinKit] [SRTSocket.swift:102] createConnectionException() > Connection setup failure: connection time out

i cann't push stream , I don't konw how to fix this bug , Can you help me to fix this bug. thanks very mush.

Use correct Transport Stream standard for SRT

Unable to stream to SRS 4.0

https://github.com/ossrs/srs/
https://github.com/ossrs/srs/blob/4.0release/trunk/src/srt/ts_demux.cpp

Crashes SRS with error
srs: ./src/srt/ts_demux.cpp:415: int ts_demux::pes_parse(unsigned char*, size_t, unsigned char**, size_t&, uint64_t&, uint64_t&): Assertion 0x80 == p[pos]' failed.
`
I believe this is due to TSWriter. OBS and FFMPEG work fine so I believe it is the config in Hashinkit.
Here is the defaults for FFMPEG
https://ffmpeg.org/ffmpeg-formats.html#mpegts

I am looking into this but I would love it if someone else can also attempt to take a look at solving this.

VTDecompressionSessionDecodeFrame fails with OSStatus=-12909

Discussed in #56

^{Originally posted by martinzsapka May 10, 2023}
Hello!

I'm trying to receive an h264 srt stream, but the decoder fails with error OSStatus=-12909. Specifically, the VTDecompressionSessionDecodeFrame call. Of course because of that, I don't get any imagebuffer.

Do you have any guesses as to what I may have misplaced? Maybe some configuration is missing?

Thanks!
