This page is documenting a work in progress feature do not assume it is available on the mainline branch.


AVResample is getting extended and some resamplers and mixers have additional parameters that can be user-tuned. In order to match AVScale an AVFrame-based API will be introduced.

API Design

The API extension includes

Additional options

The new avresample_open2() will match the similarly-named functions in AVCodec and AVFormat.

int avresample_open2(AVAudioResampleContext *avr, AVDictionary **opts);

AVFrame based API

The main focus had been to simplify the setup and make AVResample simpler to use.

int avresample_open_frame(AVAudioResampleContext *avr, AVFrame *out, AVFrame *in, AVDictionary **opts);

int avresample_convert_frame(AVAudioResampleContext *avr, AVFrame *out, AVFrame *in);
