+===== SRT Ingest  =====
+SRT is a relatively new streaming protocol featuring ARQ, which can theoretically support a wide range of container formats. Currently however only MPEG-TS is widely used.
+=== Stream-Format ===
+ * Transport: SRT
+ * Container: MPEG-TS
+ * Video-Streams:
+   * H.264**\*\***, 1920x1080, 25 fps
+   * For detailed recommendations see bottom of the page
+ * Audio-Streams:
+   * (atleast 1, up to 3)
+   * AAC LC, Stereo, 48KHz, 192kbit/s
+=== URLs ===
+ * Hosts:
+   * `ingest.c3voc.de`
+   * `ingest2.c3voc.de`

+ * Play:
+   * `srt://{host}:1337?streamid=play/{your_endpoint}/{auth_key}`
+=== OBS ===
+Same settings as with [[howto:3rdparty_ingest#obs-studio_example|RTMP]], but use the following in **Settings -> Stream**:
+* Service: `Custom…`
+* Server: `srt://{host}:1337?streamid=publish/{your_endpoint}/{auth_key}`
+**Audio:** Use [[https://github.com/lukas2511/obs-studio|this OBS Fork]] ([[https://cloud.cccv.de/s/bczAqcWHXX8EkL6|compiled version]]) to be able to stream multiple audio Streams (for translations).
