vorbis_encode_setup_vbr

+ +

declared in "vorbis/vorbisenc.h";

+ +

This function performs step-one of a three-step variable bitrate +(quality-based) encode setup. It functions similarly to the one-step +setup performed by vorbis_encode_init_vbr() but +allows an application to make further encode setup tweaks using vorbis_encode_ctl() before finally +calling vorbis_encode_setup_init() to +complete the setup process. + +

Before this function is called, the vorbis_info struct should be initialized by using vorbis_info_init() from the libvorbis API. After encoding, vorbis_info_clear should be called. +

+

+ + + + +
+

+extern int vorbis_encode_init_vbr(vorbis_info *vi,
+			      long channels,
+			      long rate,
+			      
+			      float base_quality);
+
+
+
+ +

Parameters

+
+
vi
+
Pointer to an initialized vorbis_info struct.
+
channels
+
The number of channels to be encoded.
+
rate
+
The sampling rate of the source audio.
+
base_quality
+
Desired quality level, currently from -0.1 to 1.0 (lo to hi).
+
+ + +

Return Values

+
+
  • +0 for success
    • + +
  • less than zero for failure:
