X265 command line for UHD-BD

[jdobbs]

Anyone have a recommended command line that will create an HEVC file that would be compliant for integration into a UHD-BD structure? I've tried several, but when I mux them the I don't get a picture on my UHD player, only audio.

I've written code that can update a structure created by TSMUXER so that it is compliant with UHD-BD, and it works correctly if I use it with an HEVC steam from a UHD-BD -- but fails when used with my output from my attempts with X265 output.

I'm pulling my hair out -- any help would be appreciated.

Can you post the command-line you tried unsuccessfully? Did you also try with --no-info? Are you using 8 bit, 10 bit or 12 bit build (or multi)? Frame rate/resolution?

I'm using a 10 bit build. I think I may have found at least one issue... the version of X265 I'd downloaded wouldn't accept "--transfer smpte-st-2084". I found another build and am trying it now.

Including the piece of information that you want to do HDR would've been important (or if you're not, you should not be using smpte-st-2084)

Gee thanks. Typical response... you ask for help and instead get criticized because you didn't ask well enough.

How about a command line example of an encode that works? Maybe one with hdr and one without? Oh, I see, you're too busy nit-picking -- and probably haven't a clue.

I guess, as usual, I'm on my own.

The cli parameter names were changed some time ago. So it just means one build is older than the other. (The actual encoding didn't change.)

This should result in a uhd-bd compliant hevc stream for HDR10 material (P3 graded with 1000nits peaks).

How about instead of insulting people you actually answer the questions you were asked, so people can help you?

There is already a thread with discussion about UHD BD x265 encoding here: https://forum.doom9.org/showthread.php?t=174491, which has a bunch of examples from people which allegedly work (I didn't test all of them), but the basic answer is that it really doesn't require many special commands, primarily either --uhd-bd or the equivalent individual options (--aud --no-open-gop --chromaloc 2), and possibly enabling hrd. And for HDR, the long list of appropriate mastering options.

So... here's a quote from your previous post...

Maybe you can help by showing me the question you asked? Not there? Yeah, I didn't think so.

I read that thread several days ago and tried pretty much every iteration I could find. None worked. I'm doing something wrong. I'll run the example provided above by excellentswordfight and see how it works.

"ffmpeg.exe" -probesize 100MB...

Thanks. I'll try the settings you provided and let you know what I find.

Unfortunately I get the same result. If I mux it into UHD-BD format and burn it to a BD-RE, the playback is a blank screen with only audio. If, however, I take the original HEVC stream and mux/burn it in exactly the same way -- it plays back correctly.

The encoded and muxed M2TS file plays back fine on my computer with Media Player Classic -- but, of course, that's no real test.

Both streams appear the same when I look at them with MEDIAINFO.

Video bitrate must not exceed 100,000 kbps. Depending on disc type bitrates have to be much lower.

[jdobbs]

Has anybody ever actually tried any of these encodes on a commercial UHD-BD Player? It just doesn't seem to work.

I lowered it to 64000 in my tests (because it's on a BD-RE disc).

[sneaker_ger]

If MediaInfo doesn't show any difference try deeper (with e.g. Zond or CodecVisa).

I downloaded a trial version of CodecVisa -- honestly I couldn't make heads or tails of most of it. I tried comparing two streams -- but it didn't seem to do anything. Is Zond any easier? I tried downloading the demo package of zond and it keeps failing.

The original file works... the second one doesn't.

I meant compare VPS/SPS/PPS. In Zond should be "Bitstream" and then expand the first NALUs. Also look for differences in general NALU structure/order (same SEIs before the picture NALUs, same order?).

Or maybe we try it the other way: you test files created by us on your player: https://www.sendspace.com/file/ezphty

I have created a BD structure with the tsmuxer (UHD mkv). Then edited as specified with the TSMUhdmuxer. Unfortunately, only audio and no picture is playable on the player

What did you use as a source? Was it reencoded?
