All Recordings are Failing as Damaged at Between 1 and 5 Mins in Length

Post by crum » Tue Aug 28, 2018 2:44 am

I've completed the initial setup of my MythTV and have been experimenting with recording. All of the recordings I have tried over the last week are failing between 1 and 5 mins in length w/ file sizes varying between 82 mb and 440 mb.

BACK-END SETUP:
Operating System - Ubuntu 18.04.01 LTS (Server)
Kernel - 4.15 (tried both the generic and the hauppauge media tree version) -- current output of uname -a is: Linux mythtv-server 4.15.0-29201807270420-generic #0+mediatree+hauppauge-Ubuntu SMP Fri Jul 27 18:09:45 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
System - SUPERMICRO SYS-5018A-FTN4 1U Rackmount Server / 16 GB RAM / 2 TB HD WD Purple @ 5400 rpm - https://www.newegg.com/Product/Product. ... 6816101837
Capture card - Hauppauge 1609 WinTV-quadHD Four Tuner Digital TV Receiver
Software - "mythtv-backend-master” pulled from ubuntu bionic. e.g. - .29

ERRORS and LOGS:
I am getting following error to standard output from every few seconds to few minutes... sometimes as [0] and sometimes as [1].

Code: Select all

[kernel time...] cx23885: cx23885[0]: mpeg risc op code error
[kernel time...] cx23885: cx23885[1]: mpeg risc op code error
I am getting this error with both the standard 4.15 kernel and the Hauppauge media tree version

This is the dump of /var/log/mythtv/backend.log from when an example recording starts and fails. In this case the recording failed 4:36 after starting.

EFFORTS SO FAR / TROUBLESHOOTING:
(1) I'm limiting the back-end to 1 task at a time.

(2) I've disabled auto-encoding after recording.

(3) As I've alluded to - I tried loading the Hauppauge built kernel per the instructions here: http://www.hauppauge.com/pages/support/ ... linux.html NOTE: I'm getting the cx23885 error with both kernel versions.

(4) Walking through the logs didn't give me much to work with...but I'm not a computer scientist.

(5) I found this other Mythtv-forum string that might apply - viewtopic.php?t=2249
It suggests updated V4L-DVB Device Drivers - which is why I tried the Hauppauge ppa.

(6) I've tried searching the error code and get a few threads, but I don't know what to do with them. Examples:
- https://github.com/b-rad-NDi/Ubuntu-med ... /issues/17
- https://www.linuxtv.org/pipermail/linux ... 24103.html

Not sure where to go from here. Any suggestions would be much appreciated. Happy to provide logs, etc.

I noticed that kern.log is getting really really big. Here is less than 1 second of logging... Lots of the cx23885 error.

/var/log/syslog
syslog is the same story. Again - less then 1 second of logs. Lots of the cx23885 error.

Searching for the Bug

The more I read - the more I think I have a new version of the bug discussed here.
https://github.com/b-rad-NDi/Ubuntu-med ... /issues/17

It seems that they tried to address this 6 months ago. I'm using the Hauppauge kernel. Any ideas about reaching out? I could do it directly, but I would love some help to make sure I'm communicating the right data. ALSO - I don't have a github account...

Re: All Recordings are Failing as Damaged at Between 1 and 5 Mins in Length

Post by MikeB2013 » Wed Aug 29, 2018 8:23 am

There are a few things to check/update, which may narrow down the issue.

1. The mythtv-backend-master version in Bionic repository is old, so it would be worthwhile to update to the latest version of mythtv 29 by doing the following in a terminal session:

Code: Select all

sudo add-apt-repository ppa:mythbuntu/0.29
sudo apt-get update
sudo apt-get upgrade
2. Using mythtv-setup change some settings for each of your Capture Cards, but first stop mythbackend and then go into mythtv-setup using a terminal session:

Code: Select all

sudo systemctl stop mythtv-backend
mythtv-setup
For each of your Capture Cards (there should be 4)

untick "Open xxx card on demand"
untick "Use xxx card for active EIT scan" on all but one of the Capture Cards, suggest this is only ticked on the 4th Capture Card. It is possible to have this ticked on more than one Capture Card, but it is not useful and really only serves to increase processing load.

Exit from mythtv-setup (say no to any prompts relating to starting mythbackend and mythfilldatabase)

EDIT:
Now start mythtv-backend, by rebooting the system, the mpeg risc errors you are seeing are not always cleared by restarting mythbackend.

Normally you should restart mythbackend using:

Code: Select all

sudo systemctl start mythtv-backend


Note: I am running the same Hauppauge kernel on Xubuntu Desktop 18.04.1 on motherboard Asus STRIX B250F GAMING, BIOS 1205 05/11/2018 with mythtv master (pre 30 built from source) with the QuadHD DVB version, with no issues.

Regarding logs, snippets can be misleading, it is best to post the whole log to somewhere like pastebin and post the link pastebin responds with to the file on this forum.

As an example, to put the output of dmesg command to on to pastebin, just use the following in a terminal session:

Code: Select all

dmesg | pastebinit 
http://paste.ubuntu.com/p/9RtydDZkYN/
For the mythbackend log use:

Code: Select all

pastebinit /var/log/mythtv/mythbackend.log
http://paste.ubuntu.com/p/8CckFZGryx/

Re: All Recordings are Failing as Damaged at Between 1 and 5 Mins in Length

MikeB2013 - Thank you. I didn't know about the pastebinit - very helpful.

Actions:
I added the mythbuntu PPA, upgraded and rebooted.
I also adjusted my backend settings per your comments.

Results:
- The frequency of the cx23885 error slowed down at first, but started again after the first recording.
- My recordings are still failing - but one made it almost 17 mins this time (835 MB). The others failed between 5 and 10 mins.

Logs:
dmesg log is here:

Thanks for the logs, the full dmesg output is very useful and I have raised a new issue at:

MikeB2013 - Wow! Thank you. Very kind of you to take the time.

This is a sole-purpose machine so I'm willing to experiment as needed (e.g., happy to break stuff). Note that I'm a junior hobbyist so I might need a little hand holding - or a point to a good reference - for advanced tinkering.

@crum

Brad Love at Hauppauge has responded, due to my time zone difference , I suggest you monitor the issue thread at https://github.com/b-rad-NDi/Ubuntu-med ... /issues/51

There is a utility w-scan that scans for channels which may provoke the mpeg risc errors (you are seeing a lot of these errors) so I think it is worth a try.

You need to do the following in a terminal session:

Install w-scan (sudo apt install w-scan)

stop mythtv-backend (sudo systemctl stop mythtv-backend)
disable mythtv-backend from auto starting at boot (sudo systemctl disable mythtv-backend)
reboot (sudo reboot)
then run, again in a terminal session
w_scan -fa -A1 -c US -a 0

w_scan will likely take a few minutes to run (on my system it takes around 15 minutes).

Then have a look a dmesg output for the mpeg risc errors, if present send complete dmesg output to pastebin
And finally re-enable mythtv-backend (sudo systemctl enable mythtv-backend) and start it (sudo systemctl start mythtv-backend)

@mike

I'll follow the github thread. Gonna need to buy both of you a beer after this.

TESTS:
- I installed w_scan, disabled mythtv and rebooted.
- Ran "w_scan -fa -A1 -c US -a 0" and checked for the event in dmesg three times. No dice.
- If it's important - my system did each search in about 4 mins.

LOGS:
http://paste.ubuntu.com/p/xWw7CtSF5F/

On another note:
I did see some lines indicating denied access of some type. I assume not related to this issue.

Code: Select all

[   49.213856] audit: type=1400 audit(1535675106.201:25): apparmor="DENIED" operation="open" profile="/usr/sbin/mysqld" name="/sys/devices/system/node/" pid=1349 comm="mysqld" requested_mask="r" denied_mask="r" fsuid=111 ouid=0

Running w_scan was a long shot, Brad Love thought it probably would not show the problem, he was correct. The problem is how to easily trigger the mpeg risc errors on demand. I get these errors (non-fatal) maybe one every few weeks from my QuadHD DVB card.

The w_scan run time of 4 minutes is fine, in UK we have a different standard (DVB rather than ATSC) so it takes w_scan a lot longer as there are more frequencies and transmission modes to scan.

You are correct the "audit.... " messages are not related and can be ignored.

Can you paste the output of "cat /proc/interrupts", no need to use pastebin for this - the output will be relatively small.
