OS Broadcaster app for iPhone and iPad

Live RTMP audio/video streamer to Flash Media Servers (Adobe Flash Media Server, Wowza, EvoStream, C++ RTMP Server, Red5, NGINX-RTMP-Module etc.).

Supported codecs:

- Video: Sorenson Spark (H.263)
- Audio: Speex, NellyMoser

Unfortunately we are not able to add support for H.264 and AAC codecs (these codecs are not supported by Adobe AIR). Solution for streaming in these codes to any screen is re encoding stream on the server side to the required format (with e.g. FFmpeg, Nginx-rtmp-module, Evostream, etc.).

Considering to missing H.264 and AAC codecs is not possible broadcast to mobile devices and YouTube.


Features:

- Video: Width, Height, FPS, KeyFrame, Quality, Codec Sorenson Spark
- Audio: Gain, Quality, Codec (NellyMoser, SPEEX)
- Stream: FMS URL (RTMP, RTMPT, RTMPE, RTMPS), Name, Bandwidth, Publish (Live, Record, Append)
- Monitor and Mute Functions for Camera and Microphone
- Settings AutoSave
- Logs

Connection and Stream Status Messages:

- Connecting ... (connecting to the media server)
- Connection Failed! (connection status: failed or rejected, e.g wrong URL or server rejected connection)
- Connected (connection status: success)
- Disconnected (connection status: disconnected , streaming closed)
- Streaming (stream publish start)
- Stream Failed! (e.g. bad stream name - name is already used, depends on media server type)

Some settings tips:

1. To indicate that bandwidth use takes precedence, pass a value for bandwidth and 0 for quality. OS Broadcaster transmits video at the highest quality possible within the specified bandwidth. If necessary, OS Broadcaster reduces picture quality to avoid exceeding the specified bandwidth. In general, as motion increases, quality decreases.

2. To indicate that quality takes precedence, pass 0 for bandwidth and a numeric value for quality. OS Broadcaster uses as much bandwidth as required to maintain the specified quality. If necessary, OS Broadcaster reduces the frame rate to maintain picture quality. In general, as motion increases, bandwidth use also increases.
This is Adobe AIR application.

3. To indicate that both bandwidth and quality are equally important, pass numeric values for both parameters. OS Broadcaster transmits video that achieves the specified quality and that doesnt exceed the specified bandwidth. If necessary, OS Broadcaster reduces the frame rate to maintain picture quality without exceeding the specified bandwidth.
