I have a question regarding an .m2ts streams overhead.

Since the launch of the Blu-ray disc format, way back in mid 2006, has anybody found a way to reduce an .m2ts streams overhead for non disc based applications. Or is its design set in stone?


Cheers

Yes it is set in stone: at a minimum, on each 192-byte packet there is 8 to 10 bytes of time stamp/header. Plus 3 to 4 additional packets (PMT/PAT/PCR/NIT) at least every 100 ms. Plus sync to sector size, etc.

The main purpose of a transport stream (aimed at broadcasting) is to be error resilient, so there are tons of flags and timestamps along the stream.

Yep... I can understand why broadcast TV requires to very error resistant but I find it weird that the Blu-ray disc format and the more recent AVCHD camcorder format requires the same level of resilience...

Probably the transport stream format was chosen not because of its "resilience" but because it can contain more than one program
(read: the secondary (P.I.P.) video feature).

In the new nightly 09-01, the V3 option has been put in the Blu-ray tab option, as tsMuxer now switches automatically to V3 for HEVC. The manual V3 option can still be needed e.g. to mux AVC streams, to include the m2ts along with other V3 m2ts on a disk.

Actually, you can do it yourself in any HEX editor. Open MovieObject.bdmv, find 42 82 00 00 00 00 00 00 00 00 00 0A and insert next digits BEFORE 42 82 00 00 00 00 00 00 00 00 00 0A:

51 C0 00 01 80 01 C0 01 00 00 00 00
where:
1 - number of default audio track
1 - number of default subtitle track
C - all elements in selected PGS are shown. If you need to show only elements that marked with Forced="True" flag - you need to use 8 instead of C

Additionally it is needed to replace 03 80 00 00 05 for 03 80 00 00 06

But i agree that it would be more convinient to select needed default and forced tracks from gui or cli.

Hi tymoxa, what you're explaining is also valid if it's a bluray java?

No. It's only for remuxes made by tsmuxer.

I thought maybe I could put it all together to make a menu bluray and keep that condition with the audio/subtitle. Thank you for the clarification.

Doesn't seem too difficult. I've put it as an enhancement issue on Github for the record.

Edit: the additional command can also be easily added on BDEdit.

Hi, if you want a simple thing, both ISO and folder there is the Rotty program:

Edit: I' sorry, I read that you are using the Apple system.

Sure, but not for BD3D.iso

many thanks for the update. DV remux works great on my Sony x700.

but I'm having an issue with srt subtitles which was fine using the old tsmuxer.

It looks like an issue someone raised on GitHub - is your locale set to one which uses commas for decimals?

Was the UHD Folder/ISO removed on purpose or better say merged with Blu-ray Folder/ISO on the nightly build from w64-nightly-2020-01-11--01-10-45?

Blu-ray version is now automatically switched to V3 in case HEVC is detected, so the additional combo box was unnecessary. Perhaps this pull request gives you some more information.

So when I remux a UHD I need to check V3 under Blu-ray pane?

Giving a try to the latest sub-pseudo-"release", I found:

1) the archive still doesn't include a blank .INI file; as I said before, the current developer of Roman's tsMuxeR doesn't want to know very well how Windows works and what the Windows users expect;

2) the typos weren't fixed and the stupid default settings weren't changed;

3) the "About" tab doesn't list MPEG-1 audio as a supported audio format;

4) apparently the UPX compression doesn't harm the .EXEs so I don't know why justdan96 doesn't use it. Probably he sent me to his IgnoreList because I am not sufficiently "civil" for his pusillanimous taste...

Following on from this....

I've never really understood the logic behind the 'AVCHD folder' output option, as it's never been capable of generating muxes that are compatible with the AVCHD camcorder specification (which is supposed to place all content within a 'PRIVATE' folder). Does anybody actually use this output option? Is there any point keeping it?

That being said... As I'm an OPPO player owner, it would be handy to have an 'OPPO Player' output option that created an AVCHD folder for you
