Hi,

I tried transcoding some anamorphic pal mpg files to MKV using avidemux.

In the encoder settings i checked for PAR settings: "As Input: Keep the PAR of the source video"

When playing the file in xbmc it is played as a 4-3 image in stead of 16-9. (The original MPG files plays fine (16/9) in xbmc.

This is what i find in the logging when i play the file:
tream #0.0: Video: h264, yuv420p, 720x576 [PAR 64:45 DAR 16:9], PAR 1:1 DAR 5:4, 25 fps, 25 tbr, 1k tbn, 50 tbc

xbmc seems to read the PAR & DAR correct, but then seems to change it to 1:1 and an almost 4:3.

Also the on screen info shows that is should be 64/45 ratio.


Is this an XBMC bug, or is there something wrong with the file?
Anybody know how to solve this problem?
Why does XBMC reports 2 PAR's and DAR's

I did some more testing.

It seams SMPlayer 0.6.8 (SVN r3213) also plays the file correct in 16/9 format.
Also the latest ffplay plays the file correctly. Here's the logging...

So it looks to me that it is a bug in XBMC.
Can somebody confirm this please?

I can confirm this bug using xbmc 11.0 Eden beta 1
Did you find a fix?
Did you post a bugreport?

No, I never found a solution.
The reason i wanted to recode my mpeg's to mkv was that i wanted to deinterlace them because xbmc deinterlacing was horrible at that time.
Now deinterlacing seems to work pretty well and the aspect ratio op mpeg files is ok. So for me the problem is not that urgent any more.

I did make a ticket http://trac.xbmc.org/ticket/10972 but up till now no reaction to it.

Actually I can't create a trac account, so I can't write on your bug to get attention.
I don't know what I can do

If you have a forum account then you have a trac account. They are linked. Same username and password.
