Detailed Description

The H263 codec ....

Example Usage:

    sc = Flix2_AddCodec(&codec, flix, FE2_CODEC_H263);
    // Use 450kbit
    if(sc == ON2_OK)
        sc = Flix2_CodecSetParam(codec, FE2_H263_BITRATE, 450.0);

Define Documentation

#define FE2_CODEC_H263

Codec name for use with Flix2_AddCodec().

Specifically this codec refers to the H.263 profile used within FLV.

Definition at line 42 of file h263.h.

#define FE2_CODEC_H263_BASELINE

Codec name for use with Flix2_AddCodec().

Specifically this codec refers to the baseline H.263 profile (profile 0) supported within 3GPP files amongst others.

Attention:

The baseline profile only supports the following resolutions:

• sub-QCIF (128x96)
• QCIF (176x144)
• CIF (352x288)

#define FE2_H263_BITRATE

Alias for FE2_CODECPARAM_BITRATE.

Codec parameter for stream bitrate.

Compressed stream bitrate in kbits/sec.

#define FE2_H263_KFFREQ

Alias for FE2_VCODECPARAM_KFFREQ.

Video codec parameter for keyframe frequency.

Value is in video frames. The interpretation depends on the setting of FE2_VCODECPARAM_KFINTTYPE
