Multicast + FEC local host issue #331

Closed TheSashmo closed 1 year ago

TheSashmo commented 1 year ago

Testing multicast on local host and another machine.

Source: ./UltraGrid-continuous-x86_64.AppImage -t decklink:4 -s embedded -c libavcodec:encoder=libx264:bitrate=20000k:preset=ultrafast --audio-codec=opus:sample_rate=48000:bitrate=256k --audio-capture-format channels=16 -m 1316 239.1.2.58 -T 64 --control-port 1234 -f a:rs:150:200 -f v:rs:150:200

Local host Destination 1: ./UltraGrid-continuous-x86_64.AppImage -d decklink:6 -r embedded 239.1.2.58 UltraGrid 1.8+ (master rev a2d8913 built Jul 19 2023 11:40:31)

Destination 2: /Applications/uv-qt.app/Contents/MacOS/uv -d sdl 239.1.2.58 -r coreaudio:186 UltraGrid 1.8 (tags/v1.8 rev 38c3c19 built Dec 9 2022 14:45:42)

The moment I enable UG with FEC, the local host "destination 1" crashes. Destination 2 has no issues whatsoever.

Update: Destination 2 has the same issue after updating to continuos. UltraGrid 1.8+ (master rev b77a4ac built Jul 21 2023 15:05:16)
