Hi,

I am experiencing kernel crashes with my RPI3B+. Basically I am trying to build a Linux/RPI based broadcast to multicast server. The crash occurs after I run the "azap" command (part of DVB-Tools) for a few hours (within 2 to 7 hours). I am using the Ada Fruit recommended power supply and dont see any power symbols on the screen so I am pretty confident that the power supply is fine.

OS on the RPI is Raspbian 4.14.x.

To catch the ATSC TV/Video signals, I have attached a Hauppauge WINTV HVR 950Q TV Tuner to the RPI.

I was hoping someone can help me with this.

The following is the /var/log/messages dump capture:

Please be precise in your reports. azap is part of dvb-apps, not dvb-tools.

Based on https://linuxtv.org/hg/dvb-apps, azap hasn't been updated in 4 years. The DVB APIs have been updated. Can you use dvbv5-zap (part of dvb-tools) instead? It appears to support ATSC, and is currently supported.

You are right about the dvb-apps package and I confused the two. "azap" works very well on my Intel NUC and many tutorials (https://www.instructables.com/id/Multicast-TV-Using-Raspberry-Pi-3-WinTV-HVR-955Q/) recommend using azap/tzap etc and "dvblast".

My ultimate goal is to use "dvblast", but that crashes the RPI in a very similar way to the "azap" crash. Last night I tried this on a RPI 2 with similar results, so I am assuming this is a software issue.

My next step is to try the dvbv5-zap as you recommend and see what happens, although "dvblast" is a must.

Thank you for the help and I will post my results here.

Sorry, but there's little we can really do to help. We don't have the hardware, and being based in the UK we don't have any ATSC broadcasts anyway.

The snippet you've posted from the kernel logs just tells us that a CPU has generated a Non-Maskable Interrupt (NMI) but not why. If you post the complete output then there may be more useful information. Generally we're only fussed about the kernel log part, so /var/log/kern.log or the output of dmesg are generally sufficient.

You can test with older kernels. If you use the rpi-update tool, you can provide a git hash for what you want to download. The hash corresponds to commits at https://github.com/Hexxeh/rpi-firmware/commits/master. eg sudo rpi-update fe5ebb5 would download the kernel from May 31st. If you can find the commit where the issue first arises, then it may be possible to isolate the cause of your issue without being able to reproduce it. I note from the instructables comments that people have got it working around 3 months ago. That may give a timescale for when the issue started happening.

Thanks. I will try the different kernels and get the log soon.

6by9 thanks for your suggestion about dvbv5 tools. I tried the dvbv5-zap and it has survived and overnight test run on the RPI3B+. Now there is only one more test to do with dvblast and if that doesnt produce any crashes, I will close this ticket. If that test does produce a crash and a related log, I will post them here hopefully by tomorrow.

So today I tried to run dvblast on the RPI3+ with Raspbian 4.09. I let dvblast run for about 8 hours and the RPI crashed. I am giving the kern.log below and in addition, I am getting a flashing red thermometer symbol on the display monitor. Please let me know if this makes any sense.

If you've gone back to 4.9 then you've gone back far too far. You've also gone back before the Pi 3B+ was released, hence the issues with temperature control.

Based on the instructables link people have had it working in the previous 6 months, therefore going back before that is very unlikely to be helpful.

I am starting the test now with 2018-03-13 release, which falls in the same 6 months ball park figure. Will post my results here when available.

Its crashed with that release as well. The kern.log is below. Any ideas why this might be happening?

(kern.log follows):

You didn't say at what time you started dvblast running, but I'd guess 22:14, and the crash at 22:17.

First question always in the case of random USB events is what PSU you're using and are there any low voltage warnings (lightning bolt icon in the top right of the screen). It'd be worth trying via a powered USB hub to confirm it isn't power related.

lsusb -t would be helpful to confirm which devices are disconnecting.

From a quick read I'm not 100% clear on what dvblast is streaming over the network - a single channel, or the complete multiplex? One obviously takes considerably more bandwidth than the other. dvblast is still actively developed by the looks of it. Probably worth checking out the latest code by building manually based on the instructions at https://github.com/videolan/dvblast/blob/master/INSTALL

The USB events happened because I disconnected the keyboard and mouse. I don't see any low voltage warnings (bought a Ada Fruit recommended adapter at 2.4AMPS), but I will try your suggestion about an external hub any way.

DVBLAST will zap/tune the TV TUNER to a frequency, capture the converted MPEG2 video, packetize (convert to TCP/IP/network) it and send it over a UDP multicast stream. It is a single channel.

Thanks for your support.

Slight ambiuity in your comment there.

With digital TV a single frequency will typically carry between 3 and 12 channels (more if they are radio). That is why they are typically called a multiplex or mux. They are carried as an MPEG transport stream (TS) with the total available bitrate being 15-30Mbit/s (it varies between and within ATSC, DVB-T and DVB-T2 before we even look at the satellite standards).

Either your tuner hardware or software will choose which PIDs (Packet IDs) are desired for a specific channel, or the whole mux can be received eg to allow recording of two programs within the same mux using only one tuner.

It sounds like your tuner should be picking out the PIDs for a single channel, in which case the bitrates involved should be relatively low. I'll see if I get a chance to try dvblast with DVB-T at home (there's no TV aerial in the office).

You are right with the DTV explanation, but at one time I can only get one PID with this tuner, so I am only working with one "TV channel". The bitrate is manageable at about 17 mbps for video and about 500 kbps for audio(checked with ffprobe). DVBLAST allows me to choose which PID I want after scanning (azap/tzap/dvbv5-zap etc for getting frequency/channel configurations). Good to know you are interested, but an antenna is a must.

For my next experiment, I have attached an external powered USB hub to the TV tuner instead of connecting directly to the RPI.

Ultimately, I would like to use the RPI as an IRD and maybe even an FFMPEG based transcoder (I think its too underpowered), which will eventually feed into a MPEG DASH/HLS packager for CDN based over the top video that can be played anywhere.

Not long after starting the experiment with the external hub, the RPI crashed again and the following is the output of the kern.log. This time I do see "under voltage detected". The RPI itself is connected to a 2.4AMP recommended power adapter, and the TV TUNER card to an external HUB.
