  1. Encoding:

    It is best to encode the video using a low bitrate, frame rate and low encoding complexity. For mobile streaming a total bitrate of between 64Kbps to 250Kbps is probably best. Many mobile devices may not be able to handle a full 30 frames per second (fps). A frame rate of 15 – 24 fps may be best for mobile. It is best to encode to a lower H.264 complexity. Most mobile devices only support H.264 Baseline. Encoder complexity and level is discussed here.

  2. Networking (UDP and TCP setup):

    UDP: It is best to open all UDP (0-65535) ports for RTSP/RTP streaming. On the incoming side, Wowza tends to try to use ports between the range of 6970-9999. Outgoing the port choice is made by the receiving device. So it is best to open all ports to outgoing UDP traffic. Getting the UDP setup correctly is sometimes difficult and dependent on your router and firewall setup. If behind NAT (network address translation) it is important that all UDP ports are mapped to the server running Wowza.

 

Android: Most Android devices support RTSP/RTP streaming. Newer Android devices that are running version 2.2 or greater (Froyo) also support Flash player 10.1 and can play RTMP and Flash HTTP streams. Android devices cannot play MP3 streams over RTSP/RTP in any combination (audio/video or audio only). Android devices that support Flash player 10.1 can play MP3 using RTMP or Flash HTTP. When streaming to an Android device using RTSP/RTP, the RTP portion must flow over UDP. Android does not support RTSP/RTP interleaved (RTP over TCP). This means if UDP is unavailable for RTP playback, RTP over TCP will not work as a failover and your stream will not play.

Customers have reported issues with RTSP/RTP playback on the DroidX and Droid2. It seems that only a few frame sizes will play properly on these devices:

  • 800×480
  • 480×320
  • 240×160
