Hello All,

Here's a new patch for DVB-S, DVB-S2, DVB-T and DVB-C support using S2API in combination with VDR 1.7.0. By accident I used an old source tree for the patch from 04-10-2008, which resulted in problems getting a stable lock on DVB-T and/or perhaps DVB-C. The included patch will fix that.

Enclosed are two patches. The clean patch is for a clean VDR 1.7.0 source tree patched with Reinhard's vdr-1.7.0-h264-syncearly-framespersec-audioindexer-fielddetection-speedup.diff.bz2 patch. The patched patch is for those who have used the patch from 04-10-2008.

Again, any feedback on this patch is highly appreciated!

Regards,

Niels Wagenaar

Steve can you comment the differences between s2 and s2-mfe trees and 
whether those are planned to be compined in near future?

To my understanding the only difference between s2 and s2-mfe branches 
is the support for hvr-4000 style of devices. So:

- s2:
 	--> would support only 1 frontend for 1 card at a time. Therefore 
one would need to select during the driver loading time whether to want to use 
hvr-4000 in DVB-S/S2 mode or in DVB-T mode.

So in dev-tree following are available:

[root@tinka vdr-1.7.0]# ls -la /dev/dvb/adapter0/
total 0
drwxr-xr-x  2 root   root     120 2008-10-05 10:56 ./
drwxr-xr-x  4 root   root      80 2008-10-05 10:56 ../
crw-rw----+ 1 lamikr video 212, 4 2008-10-05 10:56 demux0
crw-rw----+ 1 lamikr video 212, 5 2008-10-05 10:56 dvr0
crw-rw----+ 1 lamikr video 212, 3 2008-10-05 10:56 frontend0
crw-rw----+ 1 lamikr video 212, 7 2008-10-05 10:56 net0

- s2-mfe:
 	--> can create multiple fronends for single card eventhoughg only 
one of those can in reality to be used simultaneously. Thus one 
does not need to select between DVB-S/S2 mode and DVB-T mode 
during the driver load time. So following nodes are available:

[root@tinka vdr-1.7.0]# ls -la /dev/dvb/adapter0/
total 0
drwxr-xr-x  2 root   root      200 2008-10-05 10:56 ./
drwxr-xr-x  4 root   root       80 2008-10-05 10:56 ../

s2-mfe is work in progress. in fact there are a number of patches here:
http://dev.kewl.org/v4l-dvb/patches/

Some are specific to your card and some are related to s2api and
some are multi-frontend only.

mfe has been tested on cx88 cards but adds support for others
which has not been tested extensively and needs evaluation.

The only difference from an end-user perspective is how you describe.

If you want to rename/re-order your frontends then refer to udev
rules/script here: http://dev.kewl.org/v4l-dvb/udev/

Plus, if you use an application that can make use of both frontends
then you should apply this patch:
	http://dev.kewl.org/v4l-dvb/patches/s2-mfe-shared-retry-9036.diff

Success or failure reports when using this patch are very welcome.

Cya!
