[Matroska-users] last frame duration

Hi guys,

I have an MKV video here
https://dl.dropboxusercontent.com/u/89678527/testsmall_video.mkv

for which the whole movie duration is 4:29 and the last frame position is
3:29

The default duration is set to 0 and block_duration not set, according to
spec, I assume frame duration then will be calculated by next pts - current
pts. But the thing is, when this movie is played in MPC-HOME, total
duration shown is 3:29, when played in MPV, total duration shown 4:29 and
when it reaches 3:29, immediately jumps to the end instead of staying at
last frame for 1 min.

Could anyone help to check if the file is 100% spec-compliant ? If default
duration is 0, do I need to set last frame duration? or should it be
calculated by whole duration - last frame position?

Thanks
