Can't find, possibly not anymore?

Tested with some other file, and it fails with non-monotonic timestamps
unless you comment out some of the DVB special-case in ffmpeg.c.
So I don't think this is reproducible without the exact patch-set
that you are using.
I commented out those
//    if (enc->codec_id == CODEC_ID_DVB_SUBTITLE)
//        nb = 2;
//    else
lines, but then it works just fine, none if the issue you describe,
at least not with my sample file.
