Join a AV group (you need to have been invited first.)
Audio data callback format (same as the one for toxav_add_av_groupchat()): audio_callback(Tox *tox, uint32_t groupnumber, uint32_t peernumber, const int16_t *pcm, unsigned int samples, uint8_t channels, uint32_t sample_rate, void *userdata)
Note that total size of pcm in bytes is equal to (samples * channels * sizeof(int16_t)).
