Bug: Forced flag is not set on the forced subtitle streams

Post by _r0lZ »

When a "forced only" subtitle stream is selected in the GUI, MakeMKV does not set the MKV flag "forced" automatically.
It is relatively easy to set it manually (by typing "f" in the "MKV Flags" field of the stream), but that should be automatic. It's extremely easy for the programmer.
Please fix this bug. Thanks in advance.

Also, some BDs are authored with the forced subtitles in independent streams. In some of these BDs, all subtitles of the forced streams are flagged individually as forced. When MakeMKV detects that all subtitles of a specific subtitle stream are forced (during the creation of the MKV), it should also set the forced flag automatically. (I suppose that that can be determined only after having demuxed the whole stream, and therefore it is not possible to set the flag in the GUI before processing the title, but that doesn't mean that the flag should not be set.)

I suppose (but I have not verified) that the same bug exists in DVD mode.

Have you looked at the profile flag settings?

Code: Select all

    <!-- Common MKV flags -->
    <mkvSettings 
        ignoreForcedSubtitlesFlag="true"
        useISO639Type2T="false"
		setFirstSubtitleTrackAsDefault="false"
    />
You can change some of the default behaviors already.

Also, do you have experience with a player that actually LOOKS at the flags? I've heard mixed reports for kodi, and haven't seen a hardware player yet that uses them.

The Popcorn Hour Vten can do this. Tested it with makemkv (so subs are PGS) and had no problems.
