    Hi,

    I don't know what to say !
    But like in MP audio switching with MPC MPEG doesn't work each time, maybe some improvement must be make, i try to see the code, but i didn't succeed.
    On some m2ts, it find 3 audio stream, but only 2 is present and on some other all is good.
    Seb.

    I am using MPC-HC from xvidvideo.ru and with internal Gabest spliter (embedded into mpc-hc.exe) I have never observed bugs with presense of tracks or subs in m2ts files.

    But - there is one exception.
    If you move m2ts-file from BDMV/STREAM folder to some other place and try to open it with MPC-HC - most probably, you will observe the following bugs:
    - some tracks or subs are not shown;
    - some tracks or subs have wrong language displayed in context menu.
    MPC-HC always checks presence of ../BDMV/PLAYLIST/*.mpls data in case of m2ts-file. If these data not found, MPC-HC does wrong decisions regarding content of m2ts-file.

    So it would be difficult on only .m2ts.
    For BD structure, its maybe possible to analyse .mpls.

    On my remux, the .mpls shown this :

    I think not many information on it, could you past an example ?

    So i remake test :
    Like i try to explain, MPC Mpeg Filter has the same output pin like Haali. (So the code in MP works same.)

    But like you say for MPC-HC with .m2ts outside of his place, MP didn't find good information, the same sample in MPC-HC soft with my .m2ts (not in BD structure) it find 2 stream Audio and not 3 like MP.

    In Mediainfo (soft) all seems good too. (it find 2 audio stream) why MP find 3 ? (Maybe some ajustement must made in GetStream code).

    :D
    Seb

    EDIT :

    I try to play and it find 2 streams :
    I stop playback and restart it :

    Actually, I am not an expert on BD structure.
    Let me tell you how I guessed about importance of presence of mpls files.
    I had a lot of BDMV folders with remuxes. Basically I played m2ts files in MPC-HC and was quite satisfied with it.
    Suppose my movies' catalog structure was like this:
    Code (Text):
    1. MyMovies
    2. |- Terminator      - BDMV – STREAM – 00000.m2ts
    3. |                         - ...
    4. |                         - ...
    5. |- Face Off        - BDMV – STREAM – 00000.m2ts
    6. |                         - ...
    7. |                         - ...
    8. |- Predator        - BDMV – STREAM – 00000.m2ts
    9. |                         - ...
    10. |                         - ...
    11. |- La Vita e Bella - BDMV – STREAM – 00000.m2ts
    12.                           - ...
    13.                           - ...
    One day I decided to remove extra files kept in BDMV folders and leave only m2ts-files (which contain movies). I wanted the following structure:
    Code (Text):
    1. MyMovies
    2. |- Terminator      - Terminator.m2ts
    3. |- Face Off        - Face Off.m2ts
    4. |- Predator        - Predator.m2ts
    5. |- La Vita e Bella - La Vita e Bella.m2ts
    But when I opened some single m2ts file (which BDMV extra files I deleted) I realised the bugs with tracks & subs mentioned above.
    Then for some particular movie I restored the original BDMV extra files (which I deleted) - and again the corresponding m2ts file played properly in MPC-HC.
    Then I again started to delete those BDMV extra files - one by one.
    The minimal structure for properly played m2ts file was:
    Code (Text):
    1. SomeMovie - BDMV - STREAM - 00000.m2ts
    2.                  - PLAYLIST - ...some mpls file made by tsMuxer
    If delete this mpls file or delete PLAYLIST folder - I observed bugs.

    Unfortunately, I am not so fluent in DS-filters :(.
    Could you give me some samples? I will check them on my setup.

    Sebastiii:

    Looks like bug in M2TS splitter.
    Use DS mux to remux m2ts in to MKV. It will be working after that.

    Not all m2ts have this issue - this need to be fixed on splitter side.
    You can put subtitles in to MKV in MKV merge.

    Of course, we can convert m2ts to mkv:
    - first demux m2ts to separate video & audio streams + subtitles (using tsMuxer);
    - in case of PGS subtitles - we need to convert them to sub+idx subtitles (using BDSup2Sub);
    - next gather everything to one mkv container (using mkvmerge).

    But there are 3 difficult issues:
    - if m2ts contains PCM track - at demux it will be splitted to several files (each not more than 2 Gb);
    - if m2ts contains DolbyTrueHD track - some people could not play it using Haali splitter;
    - not all the PGS subs can be easily converted to sub+idx - I mean nice graphical subtitles (with pictures etc).

    The main advantage of mkv - possibility to name tracks & subs - like "Voiceover AC3 5.1 (over Spanish)".
    But anyway the convert described above takes a lot of time. Also we loose possibility to burn remuxes to BD-disks in future.

    So, it is not a good idea to solve the discussed problem by changing a format.

    So what is the "real" solution (not work around) right now - wait for someone to fix the filters, or?

    cheers,
