Follow @c3streaming on twitter to get up to date information.
In the following sections we try to collect some more information when to use which stream and client. Please add your own experiences.
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.
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.
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 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.
