ive had this for quite some mpeg2 sources now (non d-theater), so apparently it does not only happen quite rarely. would be nice if eac3to could be used for those as well.

@Madshi

How long do you think until there is a version that "officially" supports m2ts joining? I have a major issue with a title that requires joining of about 40 segments and which includes a TrueHD track. No matter what I do (copy /b, tssplitter join -> tsremux, etc) the audio seems to be borked and doesnt stay in sync with the video. Xport and eac3to report discontinuity issues as well.

We *really* need proper m2ts joining support within eac3to!

If it is necessary - yes. However, I've not seen a Blu-Ray title where it was necessary as of yet.

Patience, young Padawan, patience! The first eac3to version with m2ts support is just 2 days old. Code doesn't grow on trees.

h264tsto was never meant to do anything more than just automating some DirectShow filters. h264tsto never did any real work on its own. It just connected some DirectShow filters and that's it. As such there's not much that I can do to improve h264tsto. It does what it does well, and the limitations are dictated by the DirectShow filters (which are written by other people).

eac3to is a totally different thing. It does a lot of stuff on its own and only uses external software (DirectShow filters, dlls, exes) when absolutely necessary. In eac3to I've replaced several DirectShow filters which didn't work well enough (for my taste) with self written code.

until madshi tackles the multiple-m2ts titles, demuxing truehd from each m2ts separately and converting each of them separately to wav/pcm and then joining them should get you a synced track.

Don't know. Maybe? I usually don't plan that far into the future, especially not with hobby projects. I'm usually just checking what needs to be done next and then look from there...

Actually that's exactly what I did: I demuxed the True-HD track seperately from each m2ts using xport, and then converted to ac3 with eac3to. In the end I joined the ac3 segments, but still the track is borked and goes out of sync in a few scenes, apparently the track doesnt go out of sync progressively. It randomly goes out of sync on some scenes, and basically this can't be fixed by adding a delay or through stretching.

Should I rather convert the demuxed True-HD segments to WAV and then join them, and then covert them to AC3?

yes, to wav, then join, then to ac3. you should be getting progressive desync with wavs -> ac3s -> join though so don't know if joining before encoding to ac3 will help either

Feature Requet:

Madshi have you thought about adding an option for "continue to next .evo" like the one in EVOdemux? This would also be very nice once m2ts joining is implemented since there seem to be some BD titles with many .m2ts files.

I have an .m2ts file from Mr' Magorium's Wonder Emporium that makes eac3to crash. There is the chance that I'm not doing something right in preparing the file to be fed to eac3to, I'm not sure, this is my first attempt at BD. The .m2ts plays in fine in MPC with the exception of an issue seen below. How can I chop out a piece to post for inspection?

Is this what people mean by rainbow frames?



This problem seems to be only at the very end of the movie during the credits.

That won't work because audio can overlap from one segment to the next. In other words, some m2ts streams will have extra audio at the end (past the last video frame), and other streams will also have extra audio at the beginning (before the first video frame).

You would need to slice off the extra audio in WAV format before joining them to maintain sync!

How can I slice off the extra audio? And how do I know which tracks need slicing off?

vwpassion, it depends - every soundtrack may have a different slice point (ie. PCM can be off by up to 5 milliseconds, while AC3 can be off by as much as 32 millliseconds).

You would need to use a WAV editor like Adobe Audition or Audacity to check the WAVs. You would load the WAV file from one segment, then load the WAV file from the next segment, then use your eyeballs to determine the overlap point, and cut one of them so that there is no more overlap.
