If you use the MKV file to generate the Blu-ray Disc structure then txMuxeR assumes VBV values to generate NAL-HRD if no information exists.
I thought open-gop gives more efficiency (probably only slightly) so that file sizes decrease. I do not intend to encode Blu-ray compliant streams.



I ran my file (encoded with the latest rev of x264 with open-gop and muxed with mkvmerge) through mkvalidator and it returns a huge amount of messages like: "ERR0B1: Block at -1234567890 track #4 is not a keyframe". Does this have to do with open-gop and does it help to fix the issue?
