Migration to IDF 5.3.x

1. Use IDF version 5.3.x.
2. Create a new example directory. Disable the external demo project.
3. Add ESP Registry support.

hi @aquaticus
in func
static void set_dac_frequency(void)
before call
rtc_clk_apll_coeff_set(...);
need add
rtc_clk_apll_enable(1);
one of "case switch" in this function , seems to be like that:

switch(g_video_signal.dac_frequency) { case DAC_FREQ_PAL_14_75MHz: //= 14.750004 MHz rtc_clk_apll_enable(1); rtc_clk_apll_coeff_set(2, 0xCD, 0xCC, 0x07); ESP_LOGI(TAG, "DAC clock configured to 14.75 MHz. PAL 640 pixels."); break;

Thanks for spotting this.
