5.16 VP8 67
5.16.2.13 #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.
Note:
Valid range: [0,25]
Default: 0
Definition at line 245 of file vp8.h.
5.16.2.14 #define FE2_VP8_MAX_Q
Codec parameter for maximum quantizer.
Determines the quality of the output. A lower maximum number produces higher quality output.
Note:
Valid range: [0,63]
Default: 63
Attention:
Setting this value too low will likely cause the encoder to miss (i.e., overshoot) the target datarate
specified by
FE2_VP8_BITRATE and, should FE2_VP8_DROP_THRESH be enabled, result in a
large amount of dropped frames. The table mentioned above should be used as a guide in choosing a
reasonable value based on the bitrate.

5.16.2.15 #define FE2_VP8_MB_STATIC_THRESHOLD
Threshold for macroblocks treated static.
Note:
Default: 0
Definition at line 229 of file vp8.h.
5.16.2.16 #define FE2_VP8_MIN_Q
Codec parameter for minimum quantizer.
Determines the quality of the output. A lower minimum number produces higher quality output.
Note:
Valid range: [0,63]
Default: 4
