#1997: setdar/setsar on webm transcoding produces files with wrong aspect ratio on
Ubuntu 12.04 32 bit

-------------------------------------+-------------------------------------
I want to transcode mp4 files (with wrong DAR=5:4 and SAR=1:1) into webm
using ffmpeg and thereby set the aspect ratios to DAR=4:3 and SAR=16:15.
This works well on a machine with Ubuntu 12.04 64 bit and also on Centos
6.
However I am running Ubuntu 12.04 32bit on the production machine and
exactly this setup produces erroneous files with SAR=212:199 and
DAR=265:199 on the very same input.
The ffmpeg console output thereby contains the correct values (DAR=4:3 and
SAR=16:15) for the produced vp8 stream but ffprobe tells the afore-
mentioned values.
The result was the same for an uncompressed avi with no values for
DAR/SAR. Using setsar=16:15 and both setdar and setsar does not make a
difference.
I tried Ffmpeg versions 1.0, 1.0.1 and the current one from git with the
same result.
Differences on the other machines are:
Ubuntu 64 bit: nothing but the runtime environment.
Centos: more recent libogg (1.3.0), libvorbis (1.3.3) but older gcc (GCC)
4.4.6 20120305 (Red Hat 4.4.6-4)
I already tried both libvpx from the Ubuntu repository (1.0.0.1) and the
current git version (1.1.0) built upon
{{{
./configure --extra-cflags="-fPIC" --enable-pic --enable-shared
}}}
How to reproduce:
