FFmpeg multiplexer RTMP

[hknmtt]

Skusam rozbehat na localhoste ffmpeg tak aby som don streamoval video z OBS cez rtmp protokol a ten mi ho kovnertoval na hls stream. Nasiel som tento clanok https://www.martin-riedl.de/2018/08/24/using-ffmpeg-as-a-hls-streaming-server-part-1/

z coho mam

Kód: [Vybrat]

ffmpeg -listen 1 -i rtmp://127.0.0.1 -c:v libx264 -crf 21 -preset veryfast -c:a aac -b:a 128k -ac 2 -f hls -hls_time 4 -hls_playlist_type event stream.m3u8
Ale akosi to moc nefunguje. Ked spustim OBS stream tak to nic nerobi a po nejakom case to skape a vypluje mi to playlist s jednym kratkym videom ani neviem z ktoreho useku vysielania.

Toto mi to hodi do logu ale neviem z toho nic vycitat:

Zda sa akoby OBS neposielalo spravne stream, preto tam pise:

Kód: [Vybrat]

ale potom zase

neviem no, pride mi to ze tam ten protokol nefunguje ako by mal. Navyse tne stream sam skonci aj ked OBS vysiela. V OBS mam adresu pre stream rtmp://127.0.0.1 ale ocividne to nieco nahra takze konektivita tam je, komunikuje to medzi sebou ale nieco nie je ok proste.

Jak se povedlo nastavit výstup OBS jako rtmp server?
Měl jsem zato, že si musím spustit rtmp server mimo OBS a na ten pak nasměruji výstup z OBS.
Tak jsem to měl nastaveno při pokusech o přenos desktopu na televizi pomocí rtmp protokolu.
Použil jsem k tomu NMS https://www.npmjs.com/package/node-media-server

[hknmtt]

OBS je vysielalac ktory pouzije rtmp protokol. ffmpeg je zase rtmp server.
