[QUOTE="xppx, post: 489309, member: 55884"] [b]MPC-HC with DirectVobSub working with mix internal and external subs[/b] Perhaps this can be of interest to somebody. I stumbled on a bug (can somebody confirm this?) and looked for a solution and found one that solved the internal/external subs issues. [COLOR="DarkRed"]I managed to setup MP v1.02 in such a way with MPC-HC and DirectVobSub that [B]it currently plays anything with internal and external (or both) subtitles with CUDA[/B] ('Compute Unified Device Architecture', improved architecture and better than DXVA) [B]enabled[/B] (of course CUDA only if the movie format allows hardware acceleration).[/COLOR] [COLOR="Navy"][B][Alleged BUG][/B] In the MP Video configuration I finally needed to choose DirectVobSub over MPC-HC because MPC-HC has subtitle synchronisation issues with 1080p MKV's. [/COLOR] I tested it for 5 hours with different MKV's in different setup's (internal/external/mix subs, vobsub enabled/disabled (which shouldn't matter), etc...) but each time the subtitles were displayed 1-3 seconds too early (in case of internal subs) or too late (external subs in combination with a MKV with and without internal subs). And if you changed the subtitle language during play-time the delay would change randomly.[COLOR="Navy"][B][/BUG][/B][/COLOR] Note that this only happened with MKV's which were converted from bluray and were 1080p. All other MKV's worked fine. [B]Then I discovered that the MPC files that I put over the 1.0.2 had another great effect:[/B] [INDENT]Now the original[B] DirectVobSub also worked with internal subtitles in a MKV container out-of-the-box [/B]and on top of this it also worked for >720p MKV's [B]and with any mix of internal/external subs[/B]. You can even change the language without any effect on the subtitle synchronisation. It stays fully in sync. And icing on the cake is the [B]CUDA architecture which now enables you to run your video in HW acceleration even when using DirectVobSub[/B].[/INDENT] In my current setup in MP (via 'L') I now get the full list of all subs available: internal (if MKV) + external which is what MPC-HC promised. I tested this configuration out with different video formats (WMV, MPEG, AVI, DivX, XviD, MKV (internal, external, mix internal+external) and they all worked like a charm. And due to the specific setup of DirectVobSub the quality of the subtitles is perfect in any video resolution. =~=~= [B][I]SETUP[/I][/B] =~=~= [U]Software:[/U] [INDENT][COLOR="DimGray"]MediaPortal 1.0.2; MPC subs engine - Binaries for MP 1.0.2; MP-TVSeries v2.3.3491 (MediaPortal 1.0.2/1.1.0 Compatible); DirectVobSub 2.39; Haali Media Splitter (20090111); CoreAVC v1.9.5 (CUDA enabled); Nvidia 8500GT & Nvidia Display Drivers v190.38 (latest WHQL); FFDShow Beta 6 rev3040 (20090724) -> actually not necessary for subtitles; Xvid v1.1.3; XP SP3 (latest update 20090723) And no (polluting) codec pack(s) installed.[/COLOR][/INDENT] [U]Configuration:[/U] [INDENT][COLOR="DimGray"] [LIST] [*]MPC-HC installed over MP 1.0.2 [*]In MP Configuration:[LIST] [*]In Videos "DirectVobSub" chosen as subtitle engine with autoload ON [*]Via advanced in DirectVobSub properties:[LIST] [*]PAR compensation: Accurate Size [*]Vertical padding: extend to 16:9 (gives you the PowerDVD 'read-it-clearly' feature) [*]Double if smaller than 720x576 (produces great subtitles on lower resolution, cost is a small CPU increase) [*]Always load [/LIST][*]Personal setting: Shadow Depth of 1 [*]And finally the default language + subtitle you wish [*]For the codec settings I chose CoreAVC as H.264 video decoder.
