Vodcast Origin Operations

These are literal instructions, in time difficult parts can be replaced with scripts.

It's worth understanding each of these commands, tho, and examining the script by using cat scripts/thescript.sh before running it... it should be understood before too long.

Add a page

Assume you want to create a page A from the ispooge.com-v2 directory.

  • touch md-pages/A.md
  • Edit the page with your editor... nano in CLI, Bluefish in X.

From here we can fall back to Cryogen documentation.

Create a new playlist

Playlists are created in two parts. The playlist-Random post and optionally by the video post having the playlist-Random tag combined with a filter of same name in config.edn–creating a filtered playlist for rss readers.


+- md
   +- posts
      +- DATE-video-TITLE-ID.md
      +- DATE-playlist-NAME.md
   videos
   +- TITLE-ID.mp4
   playlists
   +- NAME-ID.json

From here, these are just pages.

Create a new video

Creating a new video is accomplished by copying it and a cover image to the $ISPOOGE_MEDIA/videos directory and running the following scripts from the ispooge.com-v2 directory.

Assuming you have files MyVideo.mp4 and MyVideo.jpg:

  • mkdir A.hls - directories can end in dot extensions, no worries
  • cd A.hls
  • ../../../tinydatacenter/ispooge.com-v2/scripts/segment-video.sh ../A.mp4 - will take time relative to length of video
  • ls -la - you should see out.m3u8 and out0.ts listed.
  • cd ../../../tinydatacenter/ispooge.com-v2
  • scripts/make-video-page.sh A > md-pages/video-A.md

The video page has in the EDN header

{:layout :video
 :tags ["video" "playlist-Random"]
}

That's it... see the Add a page section for more details.

Import a video from YouTube

Importing a video from YouTube is accomplished by using a tool to download the video file and a thumbnail. Currently it's done at the Playlist level and downloads all videos. Starting in the ispooge.com-v2 directory:

  • cd $ISPOOGE_MEDIA/videos
  • scripts/../../../tinydatacenter/ispooge.com-v2/scripts/download-video.sh VideoId
  • ls -l – note the name of the file, Title_of_Video-VideoId.mp4
  • Follow the steps from to in Create a video for the rest.

Start a live stream

Assuming you are familiar with LiveStreaming to YouTube or Twitch and use OBS, this setup should be pretty familiar. As of now the archiving and posting does not happen manually, but can be accomplished by recorded within OBS and following the process to create a new video.

If you are doing a simple local stream, you configure OBS to push to the URL

rtmp://$RASPI_IP/ispoogedaily_local` with sream key `ispoogedaily`.

Relay a live stream to YouTube, Twitch, FB Live, Periscope, etc

This is a one time setup for YouTube Live in the simplest case, or can be changed before a broadcast to change providers or use the Event system with a custom stream key for the event. From the ispooge.com-v2 directory:

  • cd ../rtmp-proxy-docker
  • Edit nginx.conf to include your credentials in the ispoogedaily_live section, configuring desired upstream providers.
  • ./build.sh
  • ./stop-proxy.sh ; ./start-proxy.sh to restart the proxy with new config
  • Ensure that OBS is pushing to ispoogedaily_live.

Use RasPi OMX Hardware Transcoding

You can safely run multiple transcoding streams via the OMX hardware. I use three and am experimenting with the best settings. Using a custom compiled ffmpeg you can get substantial speedups in video processing.
