No issue - question about composite video #62

Hello, I was following bitluni tutorials but composite video was not working on my car dvd player which has an AV input. I then tried the dali clock project which uses part of your code and ... it works ! What are the differences between your process ? Is that an issue with frequencies ? Thank you

Bitlubi library uses a different way to send the samples. It works fine only with NTSC.

I think that the ESP-8-bit based library is better. It works fine with PAL and NTSC signal.

What is the TV system in your country?

Hello I bought my DVD player in europe so I suppose it's PAL I tested both modes of ESP_8_BIT (NTSC/PAL), they both work, NTSC has overscan (some pixels are out of screen) whereas PAL displays image smaller and there are some black borders around, about 10% of screen is unused. Bitluni's code is working fine if I downgrade espressif boards version in arduino IDE to v. <=2.0.0

What's the best way to understand the code in video_out.h ? I think I will stay with this library because everything work very well !
