Linux server with HD HOMERUN DUAL DVB-C

[mwnswiss]

Hi,

I try to switch from the SageTV 7 to the new open source while in the same time switching from my old Windows XP to an Ubuntu 14.04 server.

I have a HD HomeRun Dual DVB-C which works just fine with SageTV 7 and Windows XP.

With the open source version and on Ubuntu 14.04 I get a strange behaviour, SageTV detects both tuners but it sets them as boradcast_standard=DVB-T and it obviously finds no channels during scan. I tried to just stop the server and change it to DVB-C in the Sage.properties but that doesn't work, Sage sets it back to DVB-T as soon as I start a scan.

Are there some limitations on the HD HomeRun on Linux for DVB-T? I did not spot something in the code. I have to say that I use the EU version in Switzerland.

Any hints?

OK, seems that this is the case with the built-in hdhomerun library in SageTV. I have tried now with the dvbhdhomerun (https://github.com/h0tw1r3/dvbhdhomerun) and it is most likely the same as in the other thread "Linux: Core Dump Scanning HDHR QAM". Will need to get the debug build and use gdb ...

Having discovered that, which HD HomeRun products work with the build-in hdhomerun libraries? For sure not my HD HomeRun DUAL EU version.

Cheers, Martin

I tried replacing the libhdhomerun library with the latest version from Silicon Dust but it wouldn't compile

[Taddeusz]

I successfully replaced the libhdhomerun library with the latest version from Silicon Dust. Apparently SD deprecated hdhomerun_device_firmware_version_check. There is an hdhomerun_device_get_version function so I replaced the deprecated function and got it the libHDHomeRunCapture.so to build. However, it still crashes when it hits the first channel that has something being broadcast.

[mwnswiss]

After the fix it works now, with the dvbhdhomerun driver from github . It finds channels but just when the scan finishes, it crashes with a core dump.

Stack: [0x00007f1fba47c000,0x00007f1fba57d000],  sp=0x00007f1fba57b680,  free space=1021k

v  ~StubRoutines::call_stub

This seems to happen in the C library, but I have currently no gdb setup.

The frq file for the adapter is available.

Just for info, I used the following dvbhdhomerun setup:

git clone https://github.com/h0tw1r3/dvbhdhomerun
cd dvbhdhomerun
dpkg-buildpackage -b
cd ..
dpkg -i <builtpackages>.deb (dkms and utils)

I don't know if it's helpful, but I was able to do a channel scan without crashing, using the older two-tuner HDHR device. However I couldn't get live TV to play. This was with the unmodified Linux server.

Under 64-bit scans now work ok but video capture from an HDHR does not work. Both work fine under 32-bit.

Did the scan find channels and correct you were not using the dvbhdhomerun kernel moduls?
I certainly can say that the built-in hdhomerun finds my tuners and I can start scan, but I see that it never connects to the HD HomeRun device and the list is of course always empty after scan. I saw as well that it thinks I use my HD HomeRun as DVB-T, but I use DVB-C and could find a way to change that (did not go into the code yet).

It seems related, but mine crashes as well at the end of scan, but both trace back to sage.DVBCaptureDevice.closeEncoding0 which is in source https://github.com/google/sagetv/blo...aptureDevice.c

Did not spot something obvious on 64bit, needs debugging which is next what I want get done :-)

Yeah, it found channels fine. There were a bunch of weird ones at the start. Pictures here: http://imgur.com/a/zW58v

I get signal strength, but no actual signal.

The no signal is a problem with 64-bit. Works fine in 32-bit. Don't know what causes the weird channels. On successive scans they will be disabled in favor of a real channel.

I glanced at the file a bit. Looks like you can run it in "standalone" mode, which might be useful for debugging. Some steps:

1) cd native/so/DVBCapture2.0

2) Use this pull request to fix the Makefile: https://github.com/google/sagetv/pull/25

3) Edit line 100 to enable logging to the file "Native.log"

4) make dvbtest

5) Run it something like this: LD_LIBRARY_PATH=. ./dvbtest DEVICE CHANNEL OUTFILE

It's looking for the device under /dev/dvb/DEVICE/frontend0. I don't have that. Also, I'm not sure what the channel should be. I suppose the OUTFILE format would be MPEG2 or whatever the device natively outputs.

[mwnswiss]

I made now some changes which deals with my HDHR DUAL EU (DVB-T and DVB-C). I made changes to the HDHomeRun2.0 library and now it uses correctly DVB-C if I'm on cable and DVB-T if I'm OTA.

As well I fixed the hardcoded tuner setting (alway 2 tuners), now it discovers correctly 2 or 4 tuners or whatever.

I made changes to compile this library (and only this library) on OS/X, as my DevEnv is OS/X

Only the 64bit video stream is a show stopper right now.

I know this is an older thread, but if anyone is still following this and is experiencing the same crash I think I may have a fix. I just fixed the same issue in the IVTVCapture library which was also crashing in the closeEncoding0 function on 64-bit Linux with HD-PVR.

I don't have the DVB hardware for testing, so if someone is willing to test a fix please let me know and I will post the code changes.

Yes please! I don't know if it's the same issue I was seeing, but I'd be happy to test. It's been a while since I updated my setup, so please give me the before and after code so I can test it properly.

Great! I'll put something together soon for you to test.

[mwnswiss]

The bug you refer was closed with the 64bit corrections in the native c libraries from Qian (see https://github.com/qianzhang5/sagetv...0f89a2a74bef69)

I don't have this crash anymore and it runs stable. My link referred to the HD HomeRun which is different to the HD-PVR! Could be that you still had a 32bit issue in your IVTV library but in HDHomeRun2.0 it is save now.

I recommend to make an own thread as it is most likely not related to this thread.

[troll5501]

Just to confirm, are you saying you no longer experience the crashes in sage.DVBCaptureDevice.closeEncoding0 when using 64-bit?

I am asking because the code I fixed for HD-PVR in native/IVTVCapture is nearly identical in native/DVBCapture2.0, so I'm assuming a crash will occur there for the same reason as it did with HD-PVR.

Maybe the important question is which tuner devices actually use native/DVBCapture2.0? It sounds like your devices are using the code in native/HDHomeRun2.0 so maybe that explains why it's working for you with the commit that you referenced.

Yes you are right, I messed it up. The HD Home Run devices I use and test with rely on HDHomeRun2.0 and not on DVBCapture2.0. And yes I don't have recording issues on my linux 64bit using HD HomeRun devices. I would guess now that DVBCapture2.0 probably is related to hardware DVB devices which get exposed to by a dvb kernel module.

That's exactly right. I have submitted a pull request for a similar fix to the DVBCapture2.0 library
