IIRC, the maxmum pixel clock rate is 72MHz. Even if decoding speed can reach 30fps by assistance of DSP module, the display rate can not.

The maximum supported pixel clock is 86MHz. If you're lucky, you can push it a bit higher. 1080p30 uses a pixel clock of 74.25 MHz, well within the supported range.

The memory bandwidth figures I gave apply equally to decoding on ARM, DSP or some combination of both.
