Just start it.

Additional information

I have Python 3.9.2 (accessible via python) on this machine, maybe it is related?

By the way I think it has nothing to do with python version
Haven't tried to build from source

xfangfang · 2021-08-21T15:32:46Z

It seems that this is similar to win11 启动后无法投屏
But I can't reproduce this problem on my computers win10 20h2 and win11 dev build 21996.1

Yes, this problem is not related to the local python version

The log indicates that Macast exited for some reasons when it was just starting even before the initialization was completed. Because I removed some logs that I thought will not have errors, it is regrettable that it is difficult to obtain more meaningful information from the log.

I will improve the log output of the program tomorrow. hope this can help solve the bug.

Remove all Python instances from PATH yields this (I was surprised that I have 6 Python on my PC):

The order of error messages is different (but consistently different)

xfangfang · 2021-08-21T16:27:36Z

Someone remind me that the application crash are caused by the failure of MPV to run on win11. I use MPV 0.33.0 in Macast. Can you test whether this version of MPV can run on your computer?
Or can you find an available MPV version?

chengyuhui · 2021-08-21T16:56:17Z

The package you provided works normally on my machine, at least when launched normally. However, I don't know the status of IPC, which might be the problem.

chengyuhui · 2021-08-24T05:18:48Z

The SSDPServer error seems to be coming from this:

Macast/macast/ssdp.py

Lines 97 to 100 in 17f003c

    
           try: 
        
               header, payload = data.decode().split('\r\n\r\n')[:2] 
        
           except ValueError as err: 
        
               logger.error(err)

which should be safe to ignore (malformed packets from the network)?

Now I wonder why MPV is being commanded to stop even before it is started (the message mpv ipc socket start connect never showed up, which explains why we were getting a NoneType).

For reference, a correct startup should look like this (captured on another 21H1 system):

Macast Loading Default Language en_US
MPV started
ERROR:Render:mpv ipc socket start connect
INFO:Render:{'event': 'property-change', 'id': 1, 'name': 'volume', 'data': 100.0}
INFO:Render:{'event': 'property-change', 'id': 3, 'name': 'pause', 'data': False}
DEBUG:Macast:tag_name: v0.5

xfangfang · 2021-08-24T05:53:58Z

ERROR:SSDPServer:not enough values to unpack (expected 2, got 1)

This line is caused by the closing of the SSDP thread, because the SSDP thread will be blocked while waiting to receive data, which will cause a random delay when closing this thread. Therefore, before closing the thread, I sent an empty packet to wake up the blocked thread.

Check the 1068 port of your system, Macast uses port 1068 for HTTP service. Check whether other devices can access http://[your computer's IP]:1068, such as http://192.168.1.101:1068

In my PC:

It seems that listening has failed, but I can do python -m http.server 1068 and access that server just fine, and there is nothing listening on 1068 before and after Macast is started according to resmon.

xfangfang · 2021-08-24T12:31:29Z

I still feel that some services on your system already used port 1068.

try this ?

netstat -ano | findstr 1068

chengyuhui · 2021-08-24T12:40:02Z

That command outputs nothing.

xfangfang · 2021-08-25T05:36:30Z

I wonder if this can solve your problem: https://bbs.csdn.net/topics/391900623

chengyuhui · 2021-08-25T05:44:52Z

I ran into this last weekend when writing my own SSDP/DLNA implementation in Rust for a smart speaker, and I'm pretty sure that I have fixed this problem (Python gives 10013 instead of 10048 in this case). It's not this.

xfangfang · 2021-09-02T00:08:38Z

This build adds HTTP port checking. If there is a port conflict, it will automatically switch to an available port.

xfangfang · 2021-09-11T03:16:52Z

Do you have time to test the new release? I feel this problem has been fixed.

There may be many reasons why Macast cannot be searched.
check: https://github.com/xfangfang/Macast/wiki/FAQ#unable-to-find-macast-from-your-dlna-client

After the recent update(v0.6.1), there is almost no bug feedback about this.

xfangfang · 2021-10-02T05:35:45Z

Because the original problem has been solved, closing this issue now.
If there are other problems, welcome to open a new issue.
