Frequency out of range when tuning DVB-S

[echoes]

Hi all,

I'm in the middle of upgrading to v9 and moving over from XP to Linux (Mint 17.3, 64-bit). I'm in the UK and use 2 x DVB-T and 1 x DVB-S/S2 cards

I have struggled to get a stable server working with the latest 64-bit binaries and 64-bit JVM, but I have a stable server working with the 32-bit JVM by dropping in the 9.0.4-232 Sage.jar and tweaking the startup scripts.

My Hauppauge NOVA-T-500 scans and tunes fine. (I suspect there is an issue with using both tuners on this card simultaneously, but i need to confirm).

My Hauppauge NOVA-HD-S2 card which does not find any channels when I do a scan from Sage. I can do a scan using the dvb-apps utilities and all channels are found - so the card, firmware and drivers seem to be fine.

I see errors in dmesg reporting 'frequency out of range' that appear to be due to the tuning frequency being double what it should be when doing a Sage channel scan.

I suspect that the problem may be due to line 1814 in native/so/DVBCapture2.0/sage_DVBCaptureDevice.c (tuneDVBSFrequency ) where the frequency is initially assigned to an unsigned long.
(This does not happen in the tuneDVBTFrequency function.)

So I would like to modify and rebuild the 32-bit DVBCapture2.0 library. How do I produce a 32-bit version on a 64-bit linux box using the build scripts in the github repo? Is it just a matter of setting CFLAGS in the Makefile as per this post: http://stackoverflow.com/questions/1...bit-using-make

My c days are mostly behind me, so any help is much appreciated.

Update for anyone who's interested:

No problem with using both DVB-T tuners at the same time - I had bad lineup configs.

Fixed stability issue on 64-bit by changing int types to void* types in thread_util.c/h - there is a pull request for this.

Frequency out of range problem fixed by setting lnb.high_val,low_val and switch_val properly for the IF frequency calculations. All that unsigned long stuff was a complete red-herring, and I now have sorted out a development environment.

Next steps are to use the non-legacy v4l APIs to enable DVB-S2 tuning.

Also seems to be a problem in reading the PredefinedDVBS.frq file which is resulting on a very quick and unproductive channel scan on the DBV-S card.

Could you tell me how you set these values? Think I am getting the same issue here
