Live Streaming to Client not working in 2.3.0

[dirkdamerau]

The Live UDP mpegts streaming from Server to Client is not working in Client 2.3.0 with Server 2.4.1, both running on Windows 10. Opening the UDP stream via VLC (udp://@:9250) on the Client PC is also not working. Using Client 2.0.8 works like a charm (tested Win + Mac) even on server 2.4.1. Throwing some "unused option" warnings due to the newer ffmpeg version, but working.

I can confirm, same trouble here on Windows 11.
I tried all 2.3.0 beta versions.
Live preview works fine with client 2.2.0 and lower

Presumably the updates to ffmpeg have broken the streaming command being used here. If someone can provide a new one that works, it can be updated and a new release made

I'm not sure the trouble is the ffmpeg command, it looks it is exactly the same.
If I compare the commands in casparcg server console between the 2.2 and 2.3 clients, I don't see any difference.
It looks more like a video display trouble (directshow...)...
Sometimes the preview window can appear, and I can see 1 (freeze) frame with a very big latency.

This appears to be some combination of:

• some changes in casparcg meaning the stream command is invalid (fixed by 2f77f50)
• casparcg doing something weird that means that these streams are only getting black frames (or no frames?) (confirmed with a combination of viewing the stream in standalone vlc, and forcing the client to play a stream from standalone ffmpeg)
• potentially the libvlc is not setup correctly in the client resulting in it failing to initialise. This needs confirming and fixing if true.

The logic would say it is something like your last proposition (libvlc trouble)
Because live preview works fine with clients 2.2.0 and lower (with all server versions, including last releases)
