MYTHAVTEST(1)

✨ NAME ✨

mythavtest — the MythTV AV Tester, aka the lil bestie that lets you poke the MythTV internal video player directly 💖

---

🌸 DESCRIPTION 🌸

okay so first things first, bestie: this is mythavtest version: fixes/36 [v36.0+fixes.20260401.1385cbfc60-0ubuntu3], and you can find the whole squad over at www.mythtv.org ✨

MythAVTest is a testing application that gives you direct access to the MythTV internal video player. no middleman, no cap, just you and the player 💅

🎀 Misc. Options 🎀

• -O, --override-setting — override a single setting, and you define it as a key=value pair. one setting, one override, iconic.
• --override-settings-file — point this at a file full of key=value pairs and it'll load them all up as setting overrides. bulk override energy 🫶
• -h, --help, --usage — shows you this help printout, or gives you the detailed lowdown on whichever option you picked out. very "ask and you shall receive".
• --version — displays version information. the classic.
• -vrr, --vrr — tries to enable (1) or disable (0) variable refresh rate, which is your FreeSync or GSync situation. no guessing, you literally pass the 1 or the 0 🌈

🦋 Video Performance Testing Options 🦋

• -t, --test — test video performance. that's the whole vibe of this section, tbh.
• --infile — input file URI. tell it what to chew on 🍓
• -d, --decodeonly — it decodes the video frames but does not display them. decoding in the dark, main character with the lights off 💀
• --deinterlace — deinterlaces the video frames, and yes, even if they're progressive. it said what it said.
• -gpu — allows hardware accelerated video decoders. let the GPU cook 🔥
• --nodecode — after decoding a small number of frames, the last presented frame just gets displayed over and over again, and that's on purpose — it's how you test rendering speed. like holding a pose to check the lighting ✨
• -s, --seconds — how many seconds to run the test for. default is 5.

💜 Qt Options 💜

• -display, --display — Qt (QPA) X11 connection name, for when you're using the xcb (X11) platform plugin.
• -platform, --platform — Qt (QPA) platform argument.

🧚 Logging Options 🧚

• --loglevel — sets the logging level. every log message at a lower level than the one you pick gets discarded, periodt. in descending order the levels are: emerg, alert, crit, err, warning, notice, info, debug, trace. defaults to info.
• --loglong — uses the long log format for the console, meaning it shows you the file, the line number, etc. right there in the console log. receipts included, iykyk 😭
• --logpath — writes logging messages to a file in the directory logpath, with filenames in this format: applicationName.date.pid.log. this is typically used together with --daemon, and if you use it together with --pidfile, you can pair it with log rotators — using the HUP call to tell MythTV to reload the file. teamwork makes the dream work 🫶
• -q, --quiet — don't log to the console (-q). don't log anywhere (-q -q). and no, that's not a typo, you stack them.
• --syslog — sets the syslog logging facility. set it to "none" to disable it, and it defaults to none.
• --systemd-journal — uses systemd-journal instead of syslog. out with the old 💅
• -v, --verbose — specify log filtering. use '-v help' if you want the level info, bestie, it'll spill the tea ☕

👑 User Interface Options 👑

• -geometry, --geometry — specify window size and position, in the form WxH[+X+Y].
• -nw, --no-windowed — prevents the application from running in a window. it's giving fullscreen-or-nothing ⭐
• -w, --windowed — forces the application to run in a window. for the girlies who like to multitask 🌈

💀 reminder bestie: -q -q is a real thing and --deinterlace will deinterlace even progressive frames. read before you run, ok??
