Using Opus codec in VoIP example

[goliveira]

Hello,

I am trying to use the opus codec in the VoIP example for the ESP32-LyraT V4.3, but I am having same issues.

I changed the audio stream configuration

Code: Select all

    av_stream_config_t av_stream_config = {
        .algo_mask = ALGORITHM_STREAM_DEFAULT_MASK,
        .acodec_samplerate = AUDIO_CODEC_SAMPLE_RATE,
        .acodec_type = [b]AV_ACODEC_OPUS[/b],
        .vcodec_type = AV_VCODEC_NULL,
        .hal = {
            .audio_samplerate = AUDIO_HAL_SAMPLE_RATE,
            .audio_framesize = PCM_FRAME_SIZE,
        },
    };
 

but I get the following error:
I (20386) AUDIO_THREAD: The algo_fetch task allocate stack on external memory
I (20394) AV_STREAM: audio_dec started
W (20398) SIP: CHANGE STATE FROM 16, TO 32, :func: sip_uas_process_req:1024

I tried changing the ADF Delegate stack size, ESP System Settings Event loop and main task stack sizes, but the issue persists.

Am I forgetting something ?

Thank you for your time,
Gabriel
