Hallo, ich habe Dreambox Two. Es hat alle funktioniert bis software update am 17.03. Ich habe bei mir software update check einmal pro Tag aktiviert und am 17.03 waren einige updates und seit dann funktioniert Decodierung von H.256/HEVC. Wenn ich alte nonstable image von Dreambox Two installiere - zB. dreambox-image-dreamtwo-20201010.tar.xz es geht wieder, aber es kommt Meldung für updates und wenn ich die installiere - dann geht es wieder nicht. Ich habe probiert, die updates check zu deaktivieren, aber wenn ich ein neuen plugin instabilerem möchte, dann kommen die updates auch dazu und es gehrt wieder nicht. Bitte um Info wie kann ich es umgehen? Ich habe auch DM920 und und nach letzte softaware update funktioniert alles ohne Probleme. Ich habe eine Aufnahme gemacht, downloaded und dann mit vlc angeschaut. Ohne Probleme. Alles perfekt. Nur auf Dreambox ist nicht möglich. Anbei ein Sample .ts File. Danke und LG

No,
Eurosport 2 HD Eutelsat 16A 11094/V 27500 4/5 DVB-S2 QPSK A1 Broadcasting X
North East
service ID: 1201, video PID: 1101 (HEVC/H.265), audio PID: 1102, NID: 366, TID: 30401, pilot: off
-
can you attach a recording?
-
-
assumption, maybe because of QPSK and HEVC, usually 8PSK and HEVC go together, UHD and HEVC is OK on satellite, HD and HEVC for DVB-T2 not for satellite, it is scrambled, I can´t check the picture though I can tune to the transponder
-
modulation has nothing to do with used codecs...
-
can you attach a recording?
Hello, a .ts recording is also attached in my first post

Here is a video

Thank you veravera.

Thats too short, makes no sense for testing.
FYI the root cause is that your providers broadcasting interlaced H.265 which is not really supported for by H.265 codec (H.265 must use progressive in general). Also it didn't really work before the update either, aspect ratio was broken so you saw only half sized picture and you also get only 540i not 1080i.

But on my cheap other box Amiko MINI HD is working normally same station/Eurosport 2 on 16 e/
-
Yes maybe, but still HEVC doesn't support interlaced content, there is some strange workaround which is used.
Google for "HEVC interlaced" and you'll see what I mean.
Many (or almost all) software tools can't handle it (including VLC, MPC, ffmpeg, x265...) also a lot of hardware. As said this is out of spec.Ghost may be able to make a workaround, but still the providers shouldn't use interlaced at all in combination with H.265.

So am I unlucky that i bought a dreambox two to upgrade ,,my living room" and do not go the channels I wanted to watch ?
-
As said I'm not sure this can be fixed properly, it may result in 540 lines instead of 1080. That's what you had before.

Hi, but why it is working on DM920 without a problem? If there is a recent change by provider for example last week, when it stopped working on Dreambox Two but it is still working on DM920. When I put old image(from 2020 for example) to Dreambox Two it is working again. And then when the software update on Dreambox Twois is done, it is not working anymore.
-
It's also not working properly on older Images, or do you like wrong aspect ratio and half resolution?
-
Thats too short, makes no sense for testing.
I can provide longer record for testing, but because of maximum attached size I cannot put it here as attachment
