Astrometa DVB-T2 (& linux)

PostitusPostitas warwas » 12:54, 01 Mär 2017

Ons kellegil siinsest rahvast olnud kogemust Astrometa DVB-T2 tüüneri linuxi all tööle saamisega?

Vaatamata värske V4L draiverite sortsust kokku laskmisele (või valmis mooduli proovimisele) jääb pool pulka nagu peitu - Realteki osa on näha aga Panasonicu demodulaator (mn88473) ei paista kuskilt.

Teine frontend (ehk siis see sama Pana) peaks veel näha olema. Tundub nagu pärast Realteki frontendi leidmist enam edasi ei otsitagi.

Sellises seisus on pulk tarkvarale nähtav aga ühtegi kanalit avada/leida ei suuda. Tundub nagu see Realtek'i küpsis ei suudaks iseseisvalt sisse tuleva andmevooga miskit peale hakata ja kuna Pana klots on kadunud, siis polegi pilti.
Samas Windowsi all töötab pulk ilusti- DVB-T/T2 pildi sain igatahes ette. Seega puudulikus signaalis ei saa ka asi olla.

Põhilised katsetused olen teinud Ubuntu 16.04 all (kernel 4.4) aga 16.10 on täpselt sama tark (kernel 4.8 ). Kuskilt jäi silma, et alates 4.7 kernelist peaksid need mn88473 seadmed vaikimisi toetatud olema.


Siit on näha, et seda on ikkagi võimalik kuidagi tööle saada. Samuti andis lootust üks Ungari Ubuntu foorum. Aga ise toimetades ei taha kohe mitte õnnestuda

See commit viitaks nagu hoopis sellele, mul ikaldub hoopis rtl28xxu, mitte too Pana moodul.
