Oh, hi, Martin! Long time no see.
Are you still using the old softdevice? I would have never guessed someone is still using it :-)
Yes! I was in "stealth mode" for several years, until I finally upgraded the software (Debian+VDR) from 2006 less than a year ago.
I tried to contribute some patches to make softdevice work with current VDR. It seemed that the mailing list archive was corrupted. I have been thinking of cloning the old CVS repository and committing my patches on top of it. Not that I expect anyone else to use it. It is mainly for preserving the history. :) Do you have any tips how to do that?
I'm using an ARM-Based Qnap-NAS as vdr server, it works really well with an USB DVB-T Dual-Tuner, and xineliboutput. I'm in the process of upgrading to a Cubietruck and a raspberry pi as client, but due to lack of time I have not got very far.
OK, I see. I would prefer an all-in-one solution (HDMI output, DVB-T input, Ethernet and hard disk in a single device). This would seem to be doable with an ARM board that supports SATA devices. On the RPi I would not expect it to work, due to everything sharing the single USB bus.
I am also building an all in one box based on the olinux allwinner A20 board. I have everything working (DVB-T, digitenne decoding, SATA, HDMI playback). I have connected 3 DVB-T receivers via a hub on one USB port, and the board happily recorded 3 shows, one per receiver.
I am still struggling howto get accelerated video playback going. Now the A20 uses 70% CPU to playback a SD stream. I will look into using the android driver with a linux wrapper around it. It should be doable, somebody on this list reported success (but I didn't ask him for a howto)
The board can be clocked from 90MHz .. 1GHz. I have yet to measure the power consumption, but the chip gets quite hot (about 80 degrees) when running at 1GHz continuously without heat sink.
Kind regards, Cedric
