h265 file to MKV

[Music Rockz]

Hello Guys,

I encoded AVS file to .h256 using the "x265GUI"

Preset I used:

--frame-skip 0 --bitrate 260 --tu-inter-depth=1 --tu-intra-depth=1 --rd 0 --subme=1 --me=1 --max-merge=2 --no-amp --no-rect --no-tskip

After encoding it, I muxed it with mkvtoolnix to convert to mkv, but the video didn't work properly!

I checked the avs script with AvsP and it works fine...!

Here is the screenshots and media info of the muxed video..
