flexible pipline with Codec switching (AUD-2218)

[marrog86]

Hello,

Pleas help me with the correct way to switch the Codec in respect of the http header.

Problem: Http thread hangs; onliy working with the most first Codec

function for changin codec:

audio_pipeline_breakup_elements(player->pipeline, player->currentCodec);
char *list[] =......
ESP_LOGW(TAG, "switching Decoder to %s", player->codecs[type].name);
audio_pipeline_relink(player->pipeline, list, 4);
audio_pipeline_set_listener(player->pipeline, player->event_if);	
```	



My situation:

- setting up the pipeline for mp3 
- run http stream

-> works

- setupp the pipeline for mp3, 
- relinking to wav
- relinking to mp3
- run http stream

-> works




- setting up the pipeline for wav
- relinking to mp3
- run http stream

-> error:

@marrog86 How about your problem? As your description ,instead audio_pipeline_unlink break the pipeline, then linked a new one.

[marrog86]

It seems for me tat it is not possible to abort end reset he elements correctly. So y made a complete stop procedure (with wait until stop) like in the examples before starting new one. This takes a lot of time for Music which yet should not be played so i tried to avoid this.

Would be great having an fast cancel y forget all buffer data Procedure for starting new Tracks immediatly without making the hole stopping procedure.

I dont have my code here in this moment, If it helps i will take once again a look to my code vor giving you better information.

@marrog86 Did you find a good way to correctly to switch from one decoder to another at runtime ?
