I am confused about the ai saying DMA
DMA (Direct Memory Access) is King:
The ESP32-S3's highly optimized SPI with DMA is the dominant factor. It allows the ESP32-S3 to transfer large amounts of data to the display with minimal CPU intervention.
The RV1103 (Luckfox Pico Mini A) lacks the same level of DMA optimization. This forces the CPU to handle a much larger portion of the SPI data transfer, creating a significant bottleneck.
Is this true?
Its only 172x320 24fps video mjpeg low quality that i wana play
CONFUSE ABOUT SPI?

Hello，the RV1103 has weaker DMA optimizations, but for this low-resolution, low-frame-rate video its performance is probably still adequate, especially if you're not demanding on CPU usage.
