In the following sections we try to collect some more information when to use which stream and client. Please add your own experiences.

RTMP

RTMP only works with native clients like VLC/mplayer or flash. They contain a h.264 stream and there is one stream per available resolution/quality which have to be switch manually if needed. This one of the stream types with lower latency. In the CCH you can expect around 15 seconds.

The player on the website falls back to rtmp and therefore flash if nothing else works.

HLS

HTTP live steams (HLS) contain h.264/MPEG AVC video and should work on

most iOS devices

Android with native (since Android 4) Daroon Player

PCs with VLC >1.2 current FFMPEG (see below) current mplayer Quicktime X Safari webbrowser



If you choose the "Auto"-Stream URL, your player will choose the optimal quality for your connection. Rewinding to the past, also known as VOD or Relive is currently not supported.

WebM

This http stream uses VP8 as video codec and Vorbis for audio. They should work natively in on PC in Firefox, Chrome and Android ≥ 4.

Audio

Audio only streams are good if you don't need video or only have low bandwidth (e.g. mobile phone). MP3 should be played with nearly every player out there. Opus works in VLC and is even more bandwidth-friendly.

Images

As an alternative to video or as an addition to audio-only there is a page, where you can follow the video streams by screenshots only. This uses very low bandwidth and gives you an idea of what's happening. You can read the slides and see a face to what you hear, but nothing more. 30c3.m00n.eu You can use the images provided to create your own screenshot page as well and post it here.
