Pi for Video processing and video hardware acceleration

Tue Aug 20, 2019 7:33 pm

Hi Geeks,

I am looking for a decent video platform which will capable for decode and encode hd videos at same time . Is Pi good choice for video programming ? If yes then which model is good , Any hardware expert please suggest me . Thanks in advance .

What are the specific requirements with regard to resolution and frame rate?

Jamesh thanks for quick reply !!

Following are the details for specific resolution and FPS:

3840 x 2160
4096 x 2160
1920 x 1080
1080 x 720
fps 25 - 30
I can also go for 60 fps as well .


Is Pi board have dedicated video hardware accelerator or it is using cpu for decoding or encoding frames .

Please let me know if you required any information related to my question . I hope now you can answer . Thanks !!

All Pis (including the Zero) can do 1080p30 H.264 encode and decode, via the OpenMAX stack. The Pi 4 can decode (only) H.265 at up to 4Kp60, via a discrete block on the chip which is not addressable via OpenMAX.

Please note that the H.264 encoder cannot handle interlaced content.

All of which has been mentioned around these parts on numerous occasions, and isn't difficult to find.

Hi Dickon ,

Thanks for reply . One more question in my mind before buying this beast . When I will do any heavy processing ,suppose CPU uses 90 - 100 % then what will the temperature of Pi4 . Is there any heating issue and any internal burns during high cpu uses for long hours ? Please let me know it is very important . If you have any practical experience please share .

Get a fan for the Pi 4. It can reach throttling if under full load. In a closed case it will definitely.
