H264
[Video Codecs]

---

Detailed Description

The H264 video codec.

Example Usage:

   sc = Flix2_AddCodec(&codec, flix, FE2_CODEC_H264);
   // Use 450kbit
   if(sc == ON2_OK)
       sc = Flix2_CodecSetParam(codec, FE2_H264_BITRATE, 450.0);

Attention:

Both width and height MUST be multiples of 4 for codec setup to succeed

Apple device support

As of version 8.0.10.1 preliminary support for the iPhone has been added.
The following settings are required to enable video playback:

• FE2_H264_PROFILE set to BASE_H264PROFILE
• Resolution <= 640x480. iPhone native is 480x320, 480x360 is recommended for 4:3 content
