Note:
By default, the percentage is 15%.
The range is 0-100%.
The codec type must be
CODEC_VP6ALPHA .
For example if the maximum video bitrate was set to 500 through video_options_-
SetMaximumBitrate() , and the alpha percentage was set to 15% then the bitrate for the VP6 video
would be 425 and the alpha bitrate would be 75.
Deprecated
Use the Codec Interface along with FE2_CODEC_VP6ALPHA and the FE2_VP6A_ALPHA_-
BITRATE parameter. This function will be removed in a future release. See also: Video Codecs .
5.56.2.14 on2sc video_options_SetCompressMode (FLIX2HANDLE flix, FE2_CompressMode
mode)
Set the VP6 compression mode.
Parameters:
← flix Handle to the Flix Engine returned from Flix2_Create() or Flix2_CreateEx()
← mode Compression mode (one of FE2_CompressMode )
Return values:
ON2_OK The compression mode was successfully set in the engine.
ON2_INVALID_PARAMS The value is out of range.
ON2_NET_ERROR The underlying communication layer failed.
Note:
This setting affects VP6 only. COMPRESSMODE_BEST provides a slightly better quality image, but
takes approximately twice as long to encode as VP6 set to COMPRESSMODE_GOOD .
The default value is COMPRESSMODE_GOOD .
Deprecated
Use the Codec Interface along with FE2_CODEC_VP6 or FE2_CODEC_VP6ALPHA and the FE2_-
VP6_CXMODE or FE2_VP6A_CXMODE parameter. This function will be removed in a future re-
lease. See also: Video Codecs .
5.56.2.15 on2sc video_options_SetImageQuality (FLIX2HANDLE flix, const int32_t
lImageQuality)
Set the image quality factor.
Determines the image "quality" level. Higher numbers will generally result in higher quality video, at the
cost of higher bitrates and file sizes.
Parameters:
← flix Handle to the Flix Engine returned from Flix2_Create() or Flix2_CreateEx()
