• #define FE2_VP8_MB_STATIC_THRESHOLD
Threshold for macroblocks treated static.
• #define FE2_VP8_TOKEN_PARTITIONS
Number of token partitions.
• #define FE2_VP8_LAG
Allow lagged encoding If set, this value allows the encoder to consume a number of input frames before
producing output frames. This allows the encoder to base decisions for the current frame on future frames.
• #define FE2_VP8_THREADS
Number of threads to use A reasonable selection would be the number of cores on the system.
5.16.2 Define Documentation
5.16.2.1 #define FE2_CODEC_VP8
Codec name for use with Flix2_AddCodec() .
Definition at line 40 of file vp8.h.
5.16.2.2 #define FE2_VP8_2PASS_MAX_SECTION
VBR_2PASSControl maximum section datarate
This value is given as a percentage. The highest datarate, i.e., FE2_VP8_2PASS_MAX_SECTION% ×
FE2_VP8_BITRATE
, that can be streamed, and also the highest datarate that the encoder will allow, no
matter how difficult the section is.
Note:
Default: 400
Definition at line 198 of file vp8.h.
5.16.2.3 #define FE2_VP8_2PASS_MIN_SECTION
VBR_2PASSControl minimum section datarate
This value is given as a percentage. The lowest datarate, i.e., FE2_VP8_2PASS_MIN_SECTION% ×
FE2_VP8_BITRATE
, that the encoder will allow for any section, no matter how easy the section is. This
value is used to prevent difficult sections from stealing too many bits from easy sections.
Note:
Default: 40
