Re: Error parsing parameters

I haven't given us much to go on /work with.. That topic thread was DOA. Need to know version on MythTV & distro/kernel .. Need to know TBS model. I think / recall that TBS had pretty good out-of-the-box support. https://www.linuxtv.org/wiki/index.php/TBS_Technologies You could check startup logs to...

Re: Myth 29 - channel scan finds no channels when previously worked.

briggella w_scan is deprecated. Even if you build it from source (which you must), I recall it does not work with T2 & later T2 tuners. It may not work with current kernel v4l2-dvb media drivers. Your new ganged array antenna is much better for dvb-t/t2 than directional hi-gain as dvb-t/t2 modulatio...

Re: Diagnostic videos?

Over the years I've tried to collect every ticket or post's video sample to use for testing stuff. I was going to suggest the (in)famous 'CheeseSlices' for de-interlacing tests until came across this. https://www.isovideo.com/deinterlacing_quality_assessment.php They have a good explanation of the l...

Re: DVD menus freezing in episode section since updating to v31

Robert I doubt this has any affect on your DVD playback but.. Your GT1030 is not listed (by Nvidia) as supported by the latest legacy driver 390.. Should be using 440. Last DVD I played in MythTV was excellent (VDPAU & similar build to v0.31) The whole linux desktop/Xorg is a train wreck. Was better...

Assessment of master (new render & avsync)

Just a comment after comparing recent master to a point back near end of last year (Nov 2019). The comparison was made over a couple of nights of watching normal broadcast recordings & playing some test tracks. I tried out master (several weeks ago) after messing up my own branch so it would not com...

Re: Mythpreviewgen Not Happy

Did you pull into a new clean folder or over the top? You're using your own patches as well? I would suspect 'distclean'.. but you probably already did that. But make clean & distclean have to be run in the build folder before you pull the latest source to be totally robust & successful. Plenty of t...

Re: "No Recordings available, or screen loading..."

Could just be that the mythbackend server is not running. I would guess some update changed or broke some configuration or required component.. You could check using some system log or "top" or something similar to below... ps -AH | grep myth *buntu 18.04 or later: journalctl -xe sudo systemctl stat...

Re: Metadata lookup causes Backend to deadlock

Yes, FE was always running when it happened but that could just be down to chance & the pop-up message notifications in FE make you fully aware.

I try might disable metadata lookup for month & see if this issue stops. TV guide data here has problems anyway (everything is a movie etc).

Re: Metadata lookup causes Backend to deadlock

@jksj A very similar error happens for me (running version master from couple months back). Occurs once a week lately .. was 3 times a week a few months back. Logs imply it is metadata lookup. For me, the backend can still successfully record & respond to 'mythbackend --testsched' just all network/s...

Re: mythpreviewgen fails on MKV files with H264 video

I presume you are replacing the recorded file with the transcoded version "in-place". The original file has a seektable as recorded & it is possible that mythpreviewgen converts time t to seektable keyframe (18858) to grab an image at t. MythTV can not generate a seektable for mkv container (& MKV i...

Re: Testing Master 31pre on a ION core dumps all the time

I guess this is could be DB driver error & not a MythTV code fault/failure. There is yet another FOSS confused mess w.r.t. maria v.s mysql.

Re: Need help/advice on downgrading MythTv/MythBuntu

About 1 year ago was running master (0.30) on 14.04 & it was an appliance. Now not so much. Building master on 14.04 become very difficult (Qt etc) & a new tuner card required building LinuxTV media backports. MythTV master about 1 year ago could play Blurays titles directly of the disc.

Re: Some "media keys" not recognized in key mapping?

I wouldn't trust showkeys? or any of the X11 utilities (xbindkeys, xev etc) as they now high level event consumers. Are you sure the key events you see are complete? I find that OS or systemd or other (pulseaudio, display-manager ?) steal the special keypress events & remove/modify the keycodes. Try...

Re: v30 Could not open Decoder on LiveTV

The unwritten MythTV rule in the DVB world is never re-scan (without DB backup plan). And you do not have the same problem. Scanning for channels has nothing in common with the FE LiveTV stream probesize ffmpeg nonsense. PCTV 290e is NOT a decoder, it is a tuner that has more than its fair share of ...
