Re: I cannot play "mp4" and "m4a" files

My code has several differences from the example "pipeline_sdcard_mp3_control": - It reads USB pens instead of SD cards - It reads mp3, aac and wav files, instead of only mp3 files - It used a I2S DAC instead of a codec IC The behavior is similar if I apply a mp3 decoder in a wav file. Error is simi...

I cannot play "mp4" and "m4a" files

I am using a code altered by me from example pipeline_sdcard_mp3_control (https://github.com/espressif/esp-adf/tree/master/examples/player/pipeline_sdcard_mp3_control) and from example cli (https://github.com/espressif/esp-adf/tree/master/examples/cli) with changes to work with USB (form example msc...

Get artist a music name from MP3 file

While playing music using pipeline of audio decoding of ESP-ADF I need to get information about the mp3 music that is paying. Example of code: https://github.com/espressif/esp-adf/tree/master/examples/player/pipeline_http_select_decoder It is not clear for me that ESP-ADP libraries can easily read t...

Re: Example "msc": crash HUB: Short device descriptor transfer failed

I invested my time with ADF examples I needed to try.
I retried to compile msc example from the master branch ESP-IDF v4.4.
Now the example compiles and runs correctly.

I have no explanation. Problem aparently solved.

Re: Example "msc": crash HUB: Short device descriptor transfer failed

I redeleted the git folder and copied the original v4.4 that I made a backup "just in case". My salvation!!!! My ESP32 code now compiles again. "msc" example became more condemned because now has new errors. Miss of files in v4.4 ... what an example. I'll return to this problem again in a few days. ...

Re: Example "msc": crash HUB: Short device descriptor transfer failed

Hi ESP_Dazz. I've had a lot of problems installing the IDE. I started with VSCode + ESP-IDF for ESP32 (suggested on internet). The first uses were ok and I could develop for sometime, waiting the ESP-PROG arrival (12 days later). I had difficulty putting ESP-PROG to debug and I went to the net and i...

Re: Example "msc": crash HUB: Short device descriptor transfer failed

Thank you again @ESP_Dazz I've followed your suggestion. ESP-IDF now seems updated. I do not have yet experience with git, only svn. Unfortunately, the msc example still does not compile because of a Python error: ... File "C:/Users/emartins/ESP-IDF/tools/ldgen/ldgen.py", line 16, in <module> from l...

Re: Example "msc": crash HUB: Short device descriptor transfer failed

First, thank you @ESP_Dazz. I changed the folder of the msc example by the newest one. Now there are errors because the example uses newer libraries. For example "usb_host.h" has struct "usb_host_config_t" that is different from the stable "ESP-IDF v4.4". So I replaced the full "esp-idf" folder with...
