Stream selection (audio and subtitle) of both mp4 and mkv should work. The feature was added in MC12.
Chapter selection feature is not in yet. I can not figure out what interface is used by Haali Media Splitter for chapters.
I must have hit my head or something... I knew it worked for MP4s (I use it for that) but for some reason I thought MKVs didn't get the same love. Since the vast majority of my files are MKV instead of MP4 (due to AC3 not being supported by the MP4 container), I needed MKV support.
2) How can I set subtitles to default off?
This is a setting in VSFilter. First, do this:
1. Go to the CCCP Settings application, page 2.
2. Enable "Autoload VSFilter (WMP & MC Support)"
3. Click Apply.
That is the proper way to get VSFilter to always autoload when a subtitle stream is detected. CCCP does not do this by default because both of the included players (Zoom and MPC-HC) include built-in subtitle stream handling and don't need VSFilter.
Secondly, to configure VSFilter to load but be OFF by default (only showing subs when you request them, rather than the other way around), do this:
1. Open the
VSFilter Configuration Utility under Start --> All Programs --> CCCP --> Filters
2. Switch to the
Misc tab.
3. Check the
Hide Subtitles checkbox.
Now, VSFilter will load when Subtitle streams are included in the playing file, but no subs will be rendered unless you go into the Task Tray icon and manually enable them.
EDIT:
Please note: Setting these options works perfectly, but will cause your Taskbar to flicker at the bottom of the screen when Thumbnails are being built in the background process. This is the only way to effectively use Subtitles with MC, though.
Yet another reason why thumbnail generation should be suspended when full screen playback is active.
