Thanks, Rocky . Dunno what gave me the wrong idea. Anybody interested in the Philco detector can look at page 88 here: https://www.worldradiohistory.com/Archive-Electronics/40s/Electronics-1946-10.pdf And page 37 here: https://www.worldradiohistory.com/Archive-FM-Magazine/FM-1946-11.pdf Curly, this ...

You are most welcome Mr hubblec4! It is my pleasure to be able to help you.

By checking for TrueHD bytes, the AC3 stream is left out when the PTSs are parsed.

Not quite. They are both reported separately, just as for EAC3/AC3.

Thank you Mister hubblec4 . You are very kind. You can come out and play with Alice and me any time! For EAC3/AC3 both pusi's have the 0xb77 syncword and then you check the extra bit to distinguish them. For TrueHD it's more accurate to say that THD and AC3 are merged (hence the utility thdmerge!) r...

I'm sure you will, Mr hubblec4!

Ask if you don't grok how this derives from the PES and audio specs, or if you need copies of the specs.

Please get main5.cpp. Everything is working according to my testing. Note that MAX_ACCESS_UNITS was increased to 10000000 to allow for the large number of TrueHD minor frames. Also, sorting was removed.

Lemme know if it is not OK or if there is anything else I can help you with.

You are most welcome. I have it coded and tested for EAC3/AC3 and just have to test all the audio formats. It will detect the audio format automatically.

Regarding LPCM, I have not studied the relevant specs. For now let's stick with your empirical finding. We can come back to it if needed.

I'll get busy on number 2.

Jiminy Christmas, guys! Signs of silver mica disease (SMD) have shown up in the 49-909. Right after I put everything together and started touching up the cabinet. Ain't that a bite. Well there are only 3 cans in the FM path so let's do the dirty to them. One of the slugs is stuck so I needed to bitc...

You can have PTS without DTS but not vice versa. But it's irrelevant after what I say next. You don't care about video. Great! That means all sorting can be ditched. Yes, TrueHD has major and minor frames but no re-ordering is involved, i.e., sorting is not needed. Regarding PTS interpolation, again...

Gotcha. No worries, I didn't think that.

I'm just wrapping up the Philco 49-909 (OMG, it sounds so great), I'll start experimenting with VPL shortly. I'll probably start on Windows and then port to linux later.

I suspect that I should parse other audio formats. But for example, with an AC-3 track, the duration is always fixed at 32ms. In that case, everything is known, but if I want to parse in m2ts, it would be enough if I recognized that it was AC-3 for the PID, right? Right. So the question is whether ...

Please get main4.cpp from my misc directory as before. Here is the output when given a PID for an EAC3 track: m2tsparse G:\Rips\A_NEW_HOPE\BDMV\STREAM\00902.m2ts 1101 EAC3 duration = 0.032000 ...............................................................................................................

It is supported as far as I can see. It will take some time to get familiar with this new environment so I ask you to be a little bit patient.

Sure Mr hubblec4. I'll get started on it right away.

That stuff is now unobtainium. We can only move to VPL. I'll check if it supports SW MVC decode.

A mere 8 days later and I already have a Philco FM radio that I have restored. Holy smokes, it plays great. It sounds better than the Zenith X337 and C845! Here it is for your edification -- Philco 49-909: https://www.radiomuseum.org/r/philco_49_909.html Some low-life jumpered a blown current-limiti...

Hiya Frankaboy ! Intel dropped MediaSDK some time ago and replaced it with Video Processing Library (VPL). VPL does apparently support MVC: https://intel.github.io/libvpl/latest/programming_guide/VPL_prg_decoding.html#multi-view-video-decoding I'd be inclined to move to VPL. The problem is that VPL ...

Even that crappy C845. I guess you were doing your nails when I completed a swept alignment on it and it's performance is now indistinguishable from the X337. And it even sounds a bit better after I replaced the tweeter with a new piezo tweeter. Check it out! Even your songs sound barely tolerable ...

Guys, it seems to me that Mr hubblec4 's advance is all about correctly transcoding (or more precisely remuxing ) from seamless branched bluray to MKV. The conventional approach is to demux with gaps correction and then remux to MKV. Mr hubblec4 's new approach avoids all that. Of course, it is a wo...

Should we have some kind of sanction for abandonment like this?

You're too funny Mr hydra3333. Curly's not gonna like it.

Did I tell you about Alice's new recipe? She tried to make me eat it but I don't like broccoli. Yuck!

That utility uses standard win32 api stuff, while current DGIndexNV uses nVidia driver calls, right Rocky?

Yes, that is correct. If you needed to identify them as core versus embedded we'd have to parse more deeply.

Good news, Mr hubblec4! I'll ask Rocky to mark this resolved then. Let me know if anything else arises that needs attention. Parsing doesn't have to be anything crazy difficult, as long as you follow the spec everything will be hunky-dory.

Curly is still looking.
