Addon: mplayer plays correctly, but mencoder loses the dimensions
information when transcoding into another format using libavcodec.
E.g. transcoding the sample file using -ovc lavc -oac mp3lame -o
aspect_ratio_sample.avi results in a file that is played using the
wrong dimensions, and also at the end of the transcoding job, it
segfaults after hitting the assertion:
Assertion v>0 && v<=(1 ? 32 : 16) failed at libavutil/mem.c:225
@Carl Eugen: Is this the one you were referring to?
Transcoding using -ovc x264 -oac mp3lame -o aspect_ratio_sample.avi
does work, however, does not segfault and retains aspect ratio
