Re: [vdr] cedarX on allwinnerA20, vdr-sxfe uses more CPU than mplayer
Hi Andreas, Thanks for your answer. I will try to get softhddevice to work on my system. I see two possible routes to persue this, but both of them have problems that will take me some time to solve: 1) Debian. SoftHDdevice is not packaged in debian, so I have to compile it myself. I get an error during compiling. I will post the error here, but I am now not at my A20 board. 2)Arch linux. I have found a collection of PKGBUILDS at https://github.com/VDR4Arch/vdr4arch. This looks promising, but i have seen arch linux freeze 3 times on my A20 on the day I tried to install it. Debian runs rock-solid on the same hardware. (abeit different uSD card). I suspect it has something to do with the SOC configuration, or kernel configuration, but it will take time to figure it out. Mayby the issue goes away when I use the bootloader, kernel and .fex file from the debian image, and the userland from arch linux. As a bonus, this will also give me a much much newer version of VDR. I am indeed very interested in running VDR on an allwinner soc. I am in the final stages of assembling all the needed parts (A20 board, dvb-T receivers, hub, HD, antenna splitter, power supply, card reader) into an old DVD player casing. For now it's working OK with software decoding and SD recordings. CPU has to be running at at least 600MHz for the video to be smooth. For me it's a step forward from the old x86PC I was using.

For me it seems, that xine uses software decoding for SD MPEG2 in your case. And I don't think anyone is working on an sunxi-integration atm to bring that forward. So I recommend you to try softhddevice as the output device. It's basically working together with libvdpau-sunxi. But don't expect it to fully work. Many VDPAU functions are not implemented yet. Basic intention of libvdpau-sunxi was to write some code upon a simple framework to test the reengineered CedarX-VPU of the Allwinner SoCs. Some people tried to improve the code to make a few programs - including vdr - work together with sunxi's vdpau integration. A handful of people are trying that at the moment. Feel free to join the group :p You can get the source from https://github.com/linux-sunxi/libvdpau-sunxi and infos in the wiki at http://www.linux-sunxi.org More developers are needed, that help to improve that code. Once this will happen and every DVB-S2 codec is supported, Allwinner devices can become a full featured native vdr client using hardware decoding. It's documented, that the SoCs are supporting are hardware deinterlacing, too. But there is missing the piece of software to use that atm. Some code snippets are available though. Hoping to have cleared up sunxi-vdpau a bit and found a new guy interested in sunxi-vdr :p Linux-sunxi community is a actively developing one and not that small compared to other SoCs.
