Actually cedarX hw decoding was another question I forgot in my
previous post. I've read that it's working in linux but I didn't know
if any output devices supported it (yet)?. Was hoping softhddevice
does, or would if I sent Johns an A20. :)
I suppose you missed that vdr + softhddevice libvdpau-sunxi is working on A10/A20 hardware already and makes these devices nice fanless energy saving vdr clients. Including deinterlacing.

So first, forget the cedarx binaries and take a look at There is a libvdpau backend driver for A10/A20 devices, that supports hardwares accelerated video decoding and presentation. With johns' help we tried to improve that piece of code in the last few weeks and have now something, that is working very well imho. But it's not finished yet and not all vdpau functions are implemented. Because of the way libvdpau-sunxi uses the hardware, there are still some limitations, especially when working in windowed mode. But it's quite good useable.
You may give it a try:

There are already a few threads and howtos in the german and in iirc. It also should be no problem to make a vdr server out of one of these boxes. It's nothing else than linux on an arm box. I recommend to take a device, that has sata and put your rootfs there instead of sd card or nand. And maybe you will have some limitations due to the bandwidth (usb etc.) as with the other arm boxes as well.

Thank you. I indeed missed that vdr + softhddevice + libvdpau-sunxi exist. I will take a look at it. When I succeed in creating a functional VDR box with it, I'll add it to these howtos:

I have used the olimex A20-OLinuXino-MICRO-4GB with 3 DVB-T receivers all connected to one USB port of the A20 via a hub. my receivers can't filter the data, therefore the entire datastream is sent to the A20. When recording 3 TV shows concurrently, this is 24MB/s (192Mb/s) of data. I have almost never seen glitches in the recorded shows.

When used with samba (and large files), the A20 delivered 11MB/s from the SATA HD to the 100Mb NIC.

I can say both the USB and the SATA buses are quite capable.

Kind regards,
