Skylive-CLI

SkyLive provides non-custodial streaming solution, so you can broadcast live videos without a centralized server. This repo contains command line, however, we have some other user-friendly stuff here:

How to start stream

If you are NOT a programmer, SkyLive-GUI will be a better choise :)

• Download & extract the latest binaries from releases

• Register a SkyLive account and scheule a new stream.

• Open command prompt and start the uploader with this command: "C:\\path\to\stream_hls.exe" --record_folder "C:\\path\to\record_here". If you want to save the stream on your computer, use the --keep_files true argument.

• Enter the generated stream token from https://SkyLive.coolhd.hu/studio

• Setup OBS (below) and start recording into the 'record_here' folder!

How to finish the stream

• Click Stop recording in OBS

• Wait for every segment uploaded

• Close stream_hls.exe

• Open https://SkyLive.coolhd.hu/studio and Finish the stream (after this, the video will be seekable)

Setup OBS:

• Download & config OBS

  Currently, there is a bug in OBS, so you can't record more than 14 chunks into m3u8. While the issue is not fixed, we need to use the custom ffmpeg output, so please use the settings what you see below:

  

  • Output mode: Advanced

  • Type: Custom output (FFmpeg)

    Without FFmpeg, the recording may be stuck after 14 or 33 chunks

  • File path: .../Skylive/record_here

    You need to pass this folder in the --record_folder parameter later.

  • Container format: hls

    It records small .ts chunks, compatible with HTTP Live Streaming

  • Muxer settings: hls_time=10

    10 seconds chunks are acceptable - too large cause more delay, too small causes upload congestion.

  • Video Encoder Settings: preset=veryfast

    Saves the CPU. Available presets: ultrafast, superfast, veryfast, faster, fast, medium, slow, slower, veryslow, placebo

    Try out some, but be careful: if encoding is overloaded, viewers will experience buffering

Restream m3u8 from Youtube/Twitch

You can restream any public Youtube/Twitch stream to SkyLive without any transcoding or screen recording. The stream_downloader.py will download live stream on-demand, so you can re-upload it to SkyLive with stream_hls.py.

Start downloader:

stream_downloader.exe --record_folder "C:\\path\to" --url https://www.youtube.com/watch?v=kG5araSvvLI

Start uploader:

stream_hls.exe --record_folder "C:\\path\to"

Other tricks, notes

Build

pyinstaller --onefile stream_hls.py --hidden-import=pkg_resources.py2_warn

pyinstaller --onefile stream_downloader.py

pyinstaller --onefile benchmark_portals.py

Export HLS to mp4

After the stream, you can easily convert the .ts chunks into one mp4 file:

ffmpeg -i "http://host/folder/input.m3u8" -bsf:a aac_adtstoasc -vcodec copy -c copy output.mp4
