5.56 Deprecated 263
← lImageQuality Quality Factor (0 to 100)
Return values:
ON2_OK The quality value was successfully set in the engine.
ON2_INVALID_PARAMS The value is out of range.
ON2_NET_ERROR The underlying communication layer failed.
Note:
The default value is 75.
Deprecated
The image quality functions have been deprecated in favor of the maximum bitrate functions. Use
video_options_GetMaximumBitrate() instead.
5.56.2.16 on2sc video_options_SetKeyframeInterval (FLIX2HANDLE flix, const int32_t
lKeyframeInterval)
Set the interval between keyfames.
Determines the interval (in frames) between keyframes. Keyframes "refresh" the player with the best pos-
sible quality image, and subsequent images are derived from that image. In addition, the keyframe interval
determines the granularity at which seeking can happen (i.e., the player can only seek to a keyframe). Re-
ducing the keyframe interval increases the number of seekable points in the video. However, keyframes
take significantly more bits to encode than non-keyframes, which can result in unnecessarily large files if
the value is set too low. For most purposes, the default value is preferred.
Parameters:
← flix Handle to the Flix Engine returned from Flix2_Create() or Flix2_CreateEx()
← lKeyframeInterval Keyframe interval (in frames)
Return values:
ON2_OK The keyframe interval was successfully set in the engine.
ON2_INVALID_PARAMS The value is out of range.
ON2_NET_ERROR The underlying communication layer failed.
Note:
The default value is 12 ∗ f ramerate (12 seconds worth)
Deprecated
Use the Codec Interface along with the FE2_VCODECPARAM_KFFREQ parameter. This function
will be removed in a future release. See also: Video Codecs .
