#define FE2_CODECPARAM_BITRATE

Codec parameter for stream bitrate.

Compressed stream bitrate in kbits/sec.

Definition at line 62 of file codec_common.h.

#define FE2_VCODECPARAM_KFFREQ

Video codec parameter for keyframe frequency.

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

Enumeration Type Documentation

enum FE2_CompressMode

Valid compress modes for VP6, influences encoder speed.

For use in calls to Flix2_CodecSetParam() and Flix2_CodecGetParam() for the FE2_VP6_CXMODE and FE2_VP6A_CXMODE. For general transcoding (i.e. decoding from one compressed format and encoding to VP6) COMPRESSMODE_GOOD will provide adequate results and the best possible encode time. The quality gain using COMPRESSMODE_BEST will only be visible when using clean raw source or compressing to extremely low bitrates.

Enumerator:

COMPRESSMODE_GOOD	default. provides faster encode speed w/minimal loss of quality.
COMPRESSMODE_BEST	provides best output quality, only necessary when encoding from a raw source.

Definition at line 41 of file codec_common.h.

enum FE2_VideoBitrateControls

Encoder rate control types, influences quality.

For use in calls to Flix2_CodecSetParam() and Flix2_CodecGetParam() for the FE2_VCODECPARAM_RC_MODE parameter.

Enumerator:

CBR_1PASSControl	single pass constant bitrate
VBR_1PASSControl	single pass variable bitrate
CBR_2PASSControl	two pass constant bitrate
VBR_2PASSControl	two pass variable bitrate

Definition at line 26 of file codec_common.h.

enum FE2_VideoKeyframeTypes

Key frame interval types, influences quality.

For use in calls to Flix2_CodecSetParam() and Flix2_CodecGetParam() for the FE2_VCODECPARAM_KFINTTYPE parameter.

Enumerator:

MAX_KEYFRAMES	generate keyframes at MOST FE2_VCODECPARAM_KFFREQ apart
FIXED_KEYFRAMES	generate keyframes at a fixed interval
