Re: Occasional Failed Recordings

Possible but not likely that the recent mythtv 29 changes would have impacted recordings, a couple of changes were related to EIT scanning, but these were to do with resuming EIT scan after a timeout and only running EIT on visible channels. I only set EIT on one tuner per Video Source as this minim...

Re: Unable to watch TV

It does look like permissions issue, although I would have expected mythtv-setup complain on exit. recording folders/directories need to be owned by mythtv and also have certain permissions, so try the following to resolve sudo chown -R mythtv:mythtv /home/ed/Videos sudo chmod -R u=rwx,g=rwxs,o=rx /...

Re: Fresh load of Mythtv 0.29 on Ubuntu 18.04 database failed to start

I use the following to install mythtv 29 (or 30-pre master) on a clean install *Ubuntu 18.04, after which you can restore any previous mythconverg database backup if required. Everything is done in a terminal session. First make sure Ubuntu 18.04 is up to date sudo apt update sudo apt upgrade # if n...

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

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, i...

@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-media-tree-kernel-builder/issues/51 There is a utility w-scan that scans for channels which may provoke the mpeg risc errors (you are seeing a lo...

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

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

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: dmesg | paste...

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

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: sudo add-apt-repository ppa:mythbuntu/0.29 s...

Re: Capture cards

Before running mythtv-setup make sure mythbackend is not running, mythtv-setup on some systems does not always shutdown mythbackend. mythtv-setup requires exclusive access to the Capture Cards. For modern systems using systemd e.g. *Ubuntu 16.04/18.04, Debian Stretch/Buster etc. the sure way is to u...

Re: Encoding Failure - MPEG RISC OP CODE ERROR

I am a little surprised that you are using HauppaugeTV-quadHD DVB-T/T2/C card when your location is USA (according to this board), normally I would expect the ATSC version of the card. You can rebuild V4L to get the latest upstream media drivers, but for the way to do please see Basic approach at ht...

Re: Backend will not start

As you can get into mysql using mythtv for the user and mythtv as the password (I presume you changed it in mysql) , the other thing that might be causing issues (depends on how the Ubuntu server has been setup) is that mysql by default does not listen on external ip addresses. To allow mysql to lis...
