Orange Pi+ 2 & rpi-tv & hardware transcoding

Recommended Posts

In  a brainfart i thought the rpi gpio is compatible with most arm boards. so i took one witch i had laying around and i connected the Raspberry pi DVB-T HAT module (TV uHAT).

 

I checked if the SPI bus pins where compatible and with the help of the "Hardware_Allwinner_overlays guide" i created a overlay for the rpi-tv (used the original from the raspberry pi github).

to my surprise (after some struggle) it  work.

 

// rpi-tv HAT

/dts-v1/;
/plugin/;

/ {
	compatible = "allwinner,sun4i-a10", "allwinner,sun7i-a20", "allwinner,sun8i-h3", "allwinner,sun50i-a64", "allwinner,sun50i-h5";

	fragment@0 {
		target = <&spi0>;
		__overlay__ {
			/* needed to avoid dtc warning */
			#address-cells = <1>;
			#size-cells = <0>;

			status = "okay";

			cxd2880@0 {
				compatible = "sony,cxd2880";
				reg = <0>; /* CE0 */
				spi-max-frequency = <50000000>;
				status = "okay";
			};
		};
	};

};
sudo armbian-add-overlay rpi-tv-overlay.dts

I quickly install tvheadend and went to watch some TV :p

 

Why i did this because the H3 GPU/CPU has h265 encoding (in the Nederlands tv is transmitted with the h265 1080p 50fps)

with the recent Sunxi-cedrus update libav can work with hardware encoding (in theory, i don't know it is fast enough )

But i can not find a proper recent guide the install then,  does any one installed the Sunxi-cedrus? And do i have to compile the complete  custom kernel to do this? or is this already in the main line?

onlything is can find is this: https://linux-sunxi.org/Sunxi-cedrus
