Android krabicka k TV

[Dunar]

Zaleži čo za tv maš. Na novych Philipsoch je android snaď najsvižnejši system.

Nakoniec idem vyskusat spominany W95 box, nahodim LibreELEC a uvidim. Ide hlavne o passtrough dts, cize ak to pojde, zbytocne mi davat 140e za Vero a pod.

Ja nejak nechapem, ze niekto vyuziva v Android TV nejake aplikacie

Praveze Kodi na svojej telke mam pustene dost casto a spokojny, hovorim, keby nebol teraz problem pri kupe domaceho kina, ze neprepusti dts signal tak ani dalsiu krabicku neriesim.

Nuz, to sa velmi mylis. Kodi pouziva standardne Android Audio API. Realna implementacia je uz nasledne zavisla od ovladacov, ktore riesi vyrobca zariadenia, resp. mu doda vyrobca cipu (v tomto pripade Mediatek).

To su informacie priamo od vyrobcov (overene), nie tvoje dohady. Takže nie, nemylim. Skus im to vyvratiť, že ty vieš lepšie ako to maju dohodnute a poriešene. Oni do androidu nijako zasahovať nemôžu. Ak zisti vyrobca v systeme nejaky bug, problem (napr. ak ma odozvu od ľudi že niečo nejde), vyrobca to len referuje Googlu a oni to riešia. Nie vyrobca.
V tomto pripade je ale problem aj tak inde, kedže nativny prehravač v Sony to podporuje. Problem je len s aplikaciami tretich stran.

mylis takto nejako ?

I think Sony blocked Kodi's package id.
Me and some users tested, both Kodi 18 64bit and 32bit cannot be installed.

I compiled Kodi 32bit, changed it's package id to com.amazon.aiv.eu .
Kodi get installed and runs just fine.

Na Android TV osobne napriklad pouzivam Kodi pre lokalny content, zaroven ale napriklad aj Horizon Go (od UPC) pre streamovanie TV stanic v spalni, kde nemam coax kabel.

Mediatek ovladace (a tym teda Sony/Philips Android TV) nemaju implementovane standardne Android passthrough API, a teda preto to nefunguje korektne. Taktiez napriklad Rockchip mal specialne API, ktore ale Kodi nema zaujem podporovat/udrziavat, lebo takychto hackov by potom museli mat doslovne desiatky na nahodnych miestach.

udio Passthrough
As for audio, passthrough of multi-channel audio is pretty broken for 3rd party apps on Sony via the public Android AudioTrack APIs. While Lollipop only supported Dolby formats (AC3/EAC3) to be bitstreamed, Marshmallow finally added DTS support via API level 23. Sony/MediaTek however missed to implement it in driver land. So no DTS via the standard APIs on Sony.

There is however also another way of passing on compressed multi-channel audio by misusing the uncompressed PCM pipeline. This method is also known as “PCM hack” which Google strongly discourages app developers from using as the compressed bitstream can easily get altered along that path (e.g. by mixing it with another source like system sounds or the speech of some assistant), effectively garbling the audio that is being output, potentially harming audio hardware and even your ears.

So depending on the content and the passthrough API used by any given 3rd party app, you might very well run into one or the other problem with multi-channel audio.


Keep in mind that TVs typically only feature HDMI inputs, so no outputs, meaning that we are limited to HDMI-ARC, over which lossless audio (like True HD or DTS-HD) is not explicitly specified due to bandwidth limitations. This will only change with the upcoming HDMI 2.1/eARC standard. I still believe that the good old lossy Dolby and DTS formats with 5.1 channels are enough for the average home user anyway. And all modern audio formats by Dolby and DTS have some sort of backward compatibility baked in.

Dolby Atmos can work when being carried via lossy Dolby Digital Plus (instead of True HD), but the receiver obviously also has to support that.


The pre-installed media player called Video does not suffer from the VC-1 hardware decoding and DTS passthrough restrictions as it has access to some private APIs, but is otherwise awful. Since the app lacks folder tree support, it always indexes the whole medium at once, also creating a thumbnail for each found video file. Needless to say that loading only few media files from an USB storage might already take forever, navigating them is pure horror. Using this app really makes you wanna throw a stone into its developer’s garden.


Sony/MediaTek should concentrate on standard Android APIs. What is Android’s app advantage good for anyway if the APIs don’t work as specified?

Takze mensie ozivenie, krabicka vcera dosla, neviem ako pri fullhd ale u 4k telky ked som to zapol tak to vyzeralo dost cudne, dost kostrbate by som povedal, aj ked bolo v nastaveni nativne rozlisenie. Skusil som len tak zo srandy co to ako dokaze, v nativnom prehravaci co tam bol som pustal film z externeho hdd, no hroza dost to trhalo, obraz cudny, ale dts a pod. bez problemov prepustilo. Potom hned som zacal riesit Librelec, akonahle som to nahodil, tak hned som mal usmev na tvari kodi slape ako hodinky, rozlisenie, menu normalne, predtym neviem preco to bolo kostrbate, a hlavne, passstrough funguje na vsetko, ci dts, dolby truehd atd. Takze tymto aj dakujem hubulovi, ktory ma nasmeroval, kde co hladat, a samozrejme aj za usetrenie dalsej stovky ak by som isiel do vero 4k. Cize za tu cenu spokojnost, na to, na co som to potreboval mi to ide jedna basen, cize neni o com a odporucam ak to chce clovek kvoli kodi, ale urcite radsej nahrat Libreelec.

Ktorý si objednaval? Ja som teraz máme zobral ten 96mini majú staršiu telku tak tam nemajú ani YouTube keď tam je malý chce rozprávku pustiť ani to mu nemôže a jeden ešte žene do kuchyne na Skylink až nemusím ťahať 300 kablov. Ale vyskúšal by som na tom aj toto keď už to bude doma. KODI máš ktorú verziu? Funguje aj novšia 18?

[|lucas|]

Jaj srry, mal som link pripraveny, tento, https://www.gearbest.com/tv-box/pp_7361 ... id=1640583 . Kodi tam je 17tka. Neviem ci funguje, ci sa da nahrat novsie, ono to hned po zapnuti nabehne Kodi, ak tam mas ten libreleec na karte, ktory to ma predinstalovane.

[Sugyi]

Prepinanie rozlisenia/hz funguje?

[hubula]

Ano

No prostredie ide v 60fps, akonahle zapnem film mi telka prepne na 1080/24p, 4k pri 60hz to tato kokretna krabicka nedokaze. Na to treba krabicku s procesorom s950x.
