How do i control playback on pipeline_a2dp_source_stream example? (AUD-5951)

[hqMicro]

Hi everyone!

In my application i have two ESP32 WROVER. One in Sink mode and the other is the Source. The Source is able to startup, connect and stream the music. It's OK. But at the end of the current file i need to go to the next track. I looked for examples and tryed them out but can't get this to work. And further i need to do STOP / PLAY / PAUSE / NEXT / PREV.

My attemt is as below:

        // Advance to the next song when previous finishes
        if (msg.source == (void *) fatfs_stream_reader
            && msg.cmd == AEL_MSG_CMD_REPORT_STATUS) {
            audio_element_state_t el_state = audio_element_get_state(fatfs_stream_reader);
            if (el_state == AEL_STATE_FINISHED) {
                ESP_LOGI(TAG, "[ * ] Finished, advancing to the next song");
                periph_bt_stop(bt_periph);
                
                // audio_pipeline_pause(pipeline);
                // audio_pipeline_stop(pipeline);
                // audio_pipeline_wait_for_stop(pipeline);
                
                // audio_element_set_ringbuf_done(bt_stream_writer);
                // audio_element_finish_state(bt_stream_writer);
                // audio_element_stop(bt_stream_writer);
                // periph_bt_pause(bt_periph);

                // audio_element_reset_state(mp3_decoder);

                audio_pipeline_reset_ringbuffer(pipeline);
                audio_pipeline_reset_elements(pipeline);
                audio_pipeline_change_state(pipeline, AEL_STATE_INIT);
                
                if (sys_state.sd.music.track_current < sys_state.sd.music.track_count) {
                    sys_state.sd.music.track_current++;
                    audio_element_set_uri(fatfs_stream_reader, tracks_list[sys_state.sd.music.track_current]);
                    audio_pipeline_run(pipeline);
                    periph_bt_play(bt_periph);
                }
                else {
                    sys_state.sd.music.track_current = 0;
                    audio_element_set_uri(fatfs_stream_reader, tracks_list[sys_state.sd.music.track_current]);
                    if (sys_state.sd.music.loop == true) {
                        audio_pipeline_run(pipeline);
                        periph_bt_play(bt_periph);
                    }
                }
                ESP_LOGI(TAG, "TRACK CRR: %d/%d %s", sys_state.sd.music.track_current, sys_state.sd.music.track_count, 
                                // tracks_list[sys_state.sd.music.track_current]);
                                audio_element_get_uri(fatfs_stream_reader));
            }
            continue;
        }

I (205494) TASK_BT_SRC: [ * ] Receive music info from mp3 decoder, sample_rates=44100, bits=16, ch=2, duration=0

According to the above log, the music stream starts after 90115 and ends at 199391. In my code, I set the new URI and attempt to play, but nothing happened after the last log line. I am unsure if I am checking the correct FLAG for end of play detection or resetting the pipeline operation correctly.

Thanks in advance!
