Mumudvb on NSLU2
Mumudvb run on Linksys NSLU2 http://www.nslu2-linux.org .
Someone reported me that it worked with some discontinuities in the stream on the 133MHz version of the slug.
On my 266MHz SLUG I'm able to stream three channels without problems, in the following I explain how to run MuMuDVB with OpenWRT. These explanations are also valid for other OpenWRT supported platforms :)
openWRT
Here I use an AF9015 dvb-t stick, you'll have to generate dvb.mk (see further) if you use another one which is not in the following list :

Install OpenWRT
opwnwrt Note package made following https://wiki.openwrt.org/doc/howto/creatingpackages
- get the latest version of openwrt
- install the mumudvb package file under package/mumudvb/Makefile :
http://gitweb.braice.net/gitweb?p=mumudvb;a=blob_plain;f=openwrt/package/mumudvb/Makefile;hb=refs/heads/openwrt
- install the makefile for dvb devices at package/kernel/modules/dvb.mk : (2.6.18 and a few devices)
http://gitweb.braice.net/gitweb?p=mumudvb;a=blob_plain;f=openwrt/package/kernel/modules/dvb.mk;hb=refs/heads/openwrt
- Or find the one which fit best your kernel here :
http://gitweb.braice.net/gitweb?p=mumudvb;a=tree;f=openwrt/package/kernel/modules;hb=openwrt
If you have a kernel version not listed above you can generate it using the following script (but take care about the options for the dvb core): http://gitweb.braice.net/gitweb?p=mumudvb;a=blob_plain;f=openwrt/generate_dvbmk.py;hb=openwrt
You just have to edit the kernel path at the beginning of the file and run it. It will generate a dvb.mk in /tmp/
- "make menuconfig", choose the good target, configure the IP,
- choose mumudvb under utilities
- choose your dvb card under the kernel -- DVB menu
- compile with "make V=2"
The menuconfig of the kernel will ask some questions about DVB devices, press enter until he is happy
- install the image on the slug
sudo upslug2 -i bin/openwrt-nslu2-squashfs.bin
- load the modules in the good order (on the slug)
Take care of force_pid_filter_usage=1
insmod dvb-core insmod dvb-usb force_pid_filter_usage=1 insmod dvb-pll insmod mxl5005s insmod tda18271 insmod qt1010 insmod mt2060 insmod af9013 insmod dvb-usb-af9015
- some symbolic links
mkdir /dev/dvb mkdir /dev/dvb/adapter0 ln -s /dev/dvb0.demux0 /dev/dvb/adapter0/demux0 ln -s /dev/dvb0.dvr0 /dev/dvb/adapter0/dvr0 ln -s /dev/dvb0.frontend0 /dev/dvb/adapter0/frontend0
- install pthread
opkg update opkg install libpthread
- Try MuMuDVB

No packets dropped, works perfectly :D
The limit, in my case is three channels
Issues
If the stick doesn't have hardware ip filtering, the slug is completely lost by the amount of data (frozen if the antenna is not removed)
A dma bounce buffer outside the pool size was requested. Requested size was 0x00009A38 The calling code was : Function entered at [<c00255dc>] from [<c0029fbc>] Function entered at [<c0029eac>] from [<c013cb44>] Function entered at [<c013c9f4>] from [<c013d764>] Function entered at [<c013d540>] from [<bf150b10>] r7:c1ebaa30 r6:c11df760 r5:c11df760 r4:c11df760 ...
To find out if the device can do hardware ip filtering, you have to search if the variable caps contains DVB_USB_ADAP_HAS_PID_FILTER in the description of the device, in the source code of the module, in kernelsourcedir/drivers/media/dvb/dvb-usb/
DVB T sticks with hardware filter (2.6.18 kernel)

Mumudvb on dreambox 500
Mumudvb works on a dreambox 500 but needs some modifications
I quote the e-mail of Serge GW
--- Unfortunaly dreambox firmware use old dvb api (named "ost"). So I created patch to downgrade dvb api: Here is patch: http://tipok.org.ua/downloads/iptv/DVB/dreambox/mumudvb.2136-work.diff And I used this archived GIT snapshot (with autotools): http://tipok.org.ua/downloads/iptv/DVB/dreambox/Archive/mumudvb.tar.gz
So I started it on my dreambox and IT WORKS!! :))
But:
- autoconf=2 - is not working because iconv_open not found in GLIBC (i
think that glibc for powerpc compiled without iconv).
- Mumudvb can send only 3 channels and 1 radio station, if more - dvb
buffer will overruned and CPU 100% used.

MuMuDVB on dreambox DM500HD, DM7025, DM800 and DM8000 using opendreambox
Andreas Oberriter, a developper of opendreambox, added a recipe for MuMuDVB to his Git tree: http://git.opendreambox.org/?p=obi/opendreambox.git;a=summary
This will be merged into the opendreambox main tree later.
http://opendreambox.org/ has a quick intro on how to build the distribution. Once you're done, you'll just have to run "bitbake mumudvb" to create an installable mumudvb_1.6.ipk package.
