Description

When I play a recorded file in VLC or XBMC, I got a 4/3 aspect ratio for a 1080p stream.

File is attached.

It is rather a 1/1 aspect ratio:

+ Display unit: 3
+ Display width: 1
+ Display height: 1

This is what is specified in the ITU-T H264 document:

aspect_ratio_idc specifies the value of the sample aspect ratio of the luma samples.

Table E-1 – Meaning of sample aspect ratio indicator
aspect_ratio_idc     Sample aspect ratio       (informative)Examples of use
0                    Unspecified 
1                    1:1 ("square")            1280x720 16:9 frame without horizontal overscan                                       
                                               1920x1080 16:9 frame without horizontal overscan (cropped from 1920x1088)              
                                               640x480 4:3 frame without horizontal overscan 

So I don't think we can copy this into the mkv (according to me, it is not the display aspect ratio)
