Hi ST Team ,

previously i used the MP1 processor where the video lagging issues, so know i decided to move on another processor who can play the high resolution video above 1080 P @30FPS, 
Note: i do not want any HDMI IC's  , i want direct pin(RGB) through the processor to our HDMI port,

please suggest me which Processor should be better.

Hi @asadullah4571 

STM32MP2 series are able to play 1080p60 thru LTDC in RGB (depending on blanking required).

Note that ~150MHz clock with 24 bits RGB parallel data bus is challenging in term of general power noise and signal integrity. LTDC bus must be very short and with very low capacitive load.

We recommend to use DSI which could go up to 2048 × 1536 60 fps with much less pins and far much easier signal integrity as using low voltage differential pairs.

On STM32MP257F-DK board, we provide 1080p60 HDMI using the onboard DSI2HDMI converter (ADV7535BCBZ).

Hi @PatrickF 

I am making the project on STM32mp257 board, as you suggested but i want to  know form your side that, will it support for Chromium browser or Firefox?. in your yocto Distribution package there will be no issues with font decoding and as well as video playing.

Hi,

I don't know, MPUs product with embedded Linux are not focusing to be used with 'PC-like' browsers. You could evaluate on your side using STM32MP257F-EV board.

As far as I know, when product has an UI, it is usually done using Weston/Wayland/Gtk or Qt.

Hi @PatrickF 

I added the 3rd party layers meta-browser with x11 for MP1 board, it works and when i try to play the youtube video, it works but so much lagging issue. So i decided to move on MP2

Now I am going to purchase MP2- DK or EV board, but it should be play youtube video minimum 1080@60 without any lagging issue using  DSI2HDMI  converter . and i will use  2GB RAM DDR4.
please suggest me will it works?
