you did good things!
btw:
Technicolor's mp3 licensing program for certain mp3 related patents and software of Technicolor and Fraunhofer IIS has been terminated.
info
but i do not think, that IIS MP3 is (free) without payment - i think its only the MP3 Standard now free.
MP3 is an open ISO-MPEG-Standard but MP3 Software from IIS i think ( understand ) remains chargeable.
best wishes

Hi,
Great work on this. When I try and stream music from my Galaxy S4 phone after a while the sound slows down slightly then gets slightly choppy -- almost seems like a buffer is getting filled somewhere?
Does anyone else have this problem, is it related to the new audio_renderer refactoring?

There is a 32k buffer, when that runs empty it might get choppy. You can see it on the serial console as "buffer fill". If it gets choppy and the buffer is full, I'd like to know - that shouldn't happen.

Hi,
No mention of that
On my S4 I get
Code: Select all
I (39515) BT_APP_CORE: bt_app_task_handler, sig 0x1, 0x1
I (39515) BT_AV: a2dp audio_state_cb state 2
E (42475) BT_AV: audio data pkt cnt 100
E (45425) BT_AV: audio data pkt cnt 200
E (48325) BT_AV: audio data pkt cnt 300
E (51285) BT_AV: audio data pkt cnt 400
E (54255) BT_AV: audio data pkt cnt 500
E (57315) BT_AV: audio data pkt cnt 600
E (60835) BT_AV: audio data pkt cnt 700
I decided to test on my old galaxy s2 and it sounds perfectly good.
On both devices I get a selection of
Code: Select all
E (92955) BT: xBtuQueue failed
E (92975) BT: xBtuQueue failed
E (92995) BT: xBtuQueue failed
E (93025) BT: xBtuQueue failed
E (93045) BT: xBtuQueue failed
E (93065) BT: xBtuQueue failed
E (93095) BT: xBtuQueue failed
E (93105) BT: xHciH4Queue failed
E (93115) BT: xBtuQueue failed
E (93125) BT: xHciH4Queue failed
but that doesn't always correspond with drop in audio quality.
Puzzling!

Ah, you mean bluetooth. Didn't test that a lot, ESP-IDF does most of the work anyway so I'm not sure I can fix that. The "xBtuQueue Failed" is triggered in btu_task.c, which is Broadcom code. Its possible that we don't consume the PCM buffer fast enough, but I have no idea really.

Hi,
I'm trying to connect the web radio player to an mpd server to play locally streamed music. Are mpd http streams supported by the player? If not what are the options of streaming locally stored music to the ESP32.
Thanks,
Ethan
I'm getting this error

Looks like no proper mime type header is returned by your server. For MP3, you should return audio/mpeg. Which software are you using?
