 # yt-dlp Web UI

 A not so terrible web ui for yt-dlp.  
 Created for the only purpose of *fetching* videos from my server/nas.

+-   **It says that it isn't connected/ip in the header is not defined.**
     - You must set the server ip address in the settings section (gear icon).
 -   **The download  doesn't start.**
     - As before server address is not specified or simply yt-dlp process takes a lot of time to fire up. (Forking yt-dlp isn't fast especially if you have a lower-end/low-power NAS/server/desktop where the server is running)
--   **Background jobs are not retrieved.**

+
+### Systemd integration
+By defining a service file in `/etc/systemd/system/yt-dlp-webui.service` yt-dlp webui can be launched as in background.

+`yt-dlp-webui` now exposes a nice **JSON-RPC 1.0** interface through Websockets and HTTP-POST
+It is **planned** to also expose a **gRPC** server.

 ## FAQ
 -   **Will it availabe for Raspberry Pi/ generic ARM devices?**
     - Yes, it's currently available through ghcr.io

       If you plan to use it on a Raspberry Pi ensure to have fast and durable storage.
 -   **Why the docker image is so heavy?**
     - Originally it was 1.8GB circa, now it has been slimmed to ~340MB compressed. This is due to the fact that it encapsule a basic Alpine linux image + FFmpeg + Node.js + Python3 + yt-dlp.
--   **Am I forced to run it on port 3022?**
-    -   Well, yes (until now).
+
 -   **Why is it so slow to start a download?**
     - I genuinely don't know. I know that standalone yt-dlp is slow to start up even on my M1 Mac, so....

+## What yt-dlp-webui is not
+`yt-dlp-webui` isn't your ordinary website where downloading stuff from the internet, so don't try asking for links of where this is hosted. It's a self hosted platform for a Linux NAS.
